Samsung Q1 Pentium ordered!
Thursday, November 16, 2006
Q1 Celeron or Q1 Pentium
Additionally you can now buy used standard Q1 UMPCs on ebay at around $800, and there are hardly any used pentium versions for sale yet. So the price difference between the used Q1 and the new pentium is then a bigger one. Along with the fact that I might get a used Q1 with the Samsung organizer and keyboard for around $850 makes it a pretty good deal. I guess the question then comes down to the following:
- Is the Celeron 900 MHz good enough for the few games I want to run on it. And will I actually run games on it at all or just as a novelty? I know the kids would love it, but those games dont require much power (games for children under 6 years and so).
- Is 40 gb enough space for the software, music, pictures and movies I want to have on it? I can see myself wanting to reserve at least 20 GB for photo backup on vacations. Around 5 GB would probably be enough for music, another 10 GB for some movies (mostly cartoons for the kids). That only leaves 5 GB for the OS, software and games. That might be a bit on the low side. That extra 20 GB of the pentium edition sure sounds tempting then...
Difficult choice...

Why do you need a mouse on a UMPC?
I read that many people say that the lack of the mouse stick on the Samsung Q1 was a dealbreaker for them. I was immediately thinking, either they have very dirty fingers or they are just too big. For UMPCs I generally see two categories of usage scenarios, one where I interface with big buttons where my fingers will be good enough. And the other where I have to do more detailed work on the device. For the detailed work in the field I saw that I would most probably use a combination of the pen and/or my finger or fingernails. When in the comfortable chair in my office at work or home I would most probably have access to a mouse and keyboard as well. Even with only a keyboard I can see myself picking up the pen and click something as a faster way to do stuff than to grab the device with both hands to navigate the pointer with one hand and click with my other hand. I just never was comfortable with these on laptops either so maybe thats why I feel so sceptic about the mouse pointer.
So what does e.g. the Samsung Q1 offer instead? It has a brilliant set of shortcut buttons instead. Something I can see myself using more often than a mouse. Like jkOnTheRun I would probably configure one to toggle the IE browser fullscreen and other nice things depending on which application I am using. For a UMPC I see that the major set of applications that I am likely to run on it will be very simple interfaces with big buttons or otherwise shortcut enabled though the buttons on the device.
Current selection of UMPCs
The UMPC that has been on the market the longest time is the Samsung Q1 and hence has the widest selection of accessories as well. The original Q1 come with a Celeron 900 Mhz CPU, 512 MB ram and a 40 MB drive. The unit also get nice reviews because of its stereo sound and array microphones. It has 2 USB 2.0 ports, one Ethernet port as well as a Compact Flash port. The CF port immediately drew my attention because I could see the advantage of having this for photography backup in the field. Unfortunately tests show that the CF port is almost useless because of its slow speed at around 0,7 MB/sek tranfer rate!!! This is truly terrible as you could plug in any other USB based CF reader and get up to 16 MB/sek with a SanDisk Extreme IV card. When you are out in the field you want to empty that card as quickly as possible.
All UMPCs come with a wireless lan which is one of its major selling points. Being able to sit around in the sofa and surf the net or jot down an email at the kitchen table is nice. All of the UMPCs also come with a bluetooth interface except a nerfed down European version of the Asus R2H during its initial release. The bluetooth is a vital addition since it allows you to use a wireless keyboard and mouse as well as a bluetooth headset if you wish. The Stowaway Bluetooth keyboard is one that jkOnTheRun praises and many seem to like as the first accessory to get for any UMPC.
The Samsung Q1 comes in many more versions. In Korea, a special version of the original was released, the Q1 SSD. It has a 32 GB flash drive instead of the 40 GB 1.8" platter harddrive. The advantage of this is obvious, no moving parts, silent and fast operation. With access times under 1 ms and decent transfer speeds it boots up and loads any application way faster than a disk based version. It also consumes less power, a major benefit in a UMPC. The disadvantage though is price. Its a very costly disk that will double the price on the device. By many this is still considered the cheapest SSD drive available though. Expect this to become available in all portable devices. SSD drives is the future!
Recently Samsung also released two more versions of the Q1. A version pretty equal to the original Q1 but with a Pentium M 1 GHz with speedstep technology, newer chipset, a 60 gb hd and 1 GB memory. This is the most complete specification of the Q1 series giving you the best performance UMPC. Imagine how this could be with an SSD drive in it. The second version they released was one kitted with a Via C7 1 GHz CPU and fitting chipset. They also improved the screen on this version, but nerfed some features giving it mono speakers and mono mic as well as removing the ethernet port and the CF port. The advantage is naturally way better battery lifetime. People report of up to 4 hours on the standard 3 cell battery which is almost double that of the original Q1. If you can live with the specs and lower performance then this is definitaly the UMPC for you.
This autumn, Asus released their R2H UMPC which has a nice brushed aluminium case instead of the black plastic of the Samsung. It also has an integrated GPS, fingerprint reader and webcamera! It uses the same Celeron 900 MHz CPU as the original Samsung Q1. The first version sold in Europe was nerfed without either the gps or the webcamera as well as a 40 gb disk and 512 MB ram. The US version however had all the bells an whistles, with a 60 gb disk and 768 MB ram as well as the extended battery instead. One major letdown on the original tests of the R2H was the short battery lifetime with the standard battery, shorter than the Q1. The extended battery solves some of this, but at the same time adds bulk and weight to a device that was already more heavy than the Samsung. It is also said to become very hot and the extended battery supposedly blocks the wireless signal pretty badly compared to the Samsung Q1. The fingerprint reader is nice if you have several users of the UMPC and/or want some kind of security. The GPS has a varying degree of reported success, with some praising it and some simply not getting any signal on it at all. I have still not seen any review showing the webcamera except that people say it doesnt handle low light situations very well. Reports are also coming that the Asus does not have any L2 cache, which I find really strange as I thought this to be a standard implementation of the Celeron 900 MHz CPU. Other than that the R2H has a mono speaker and a mono mic.
TabletKiosk comes in several versions, actually the same CPU selection as the Samsung. The TabletKiosks however come with an SD card reader instead of a CF reader, and this reader supposedly performs like it should also. One major benefit of the TabletKiosk is the docking station / cradle. This is a feature that I think all UMPCs should have since it makes it so much easier to hook the device up to a monitor/ethernet/sound/keyboard/mouse just by docking the device. Other than that the TabletKiosk has a mouse pointer and buttons like the R2H, something that is missing from the Samsung UMPCs. Many say that they simply cannot live without the ability to control a mouse pointer, while I dont really understand why you need a mouse at all when you have this brilliant touch screen. More about this in a later post. A drawback of the TabletKiosk UMPCs is their price. They are a few hundred dollars more expensive than the competition. This can be a dealbreaker for many. Oh and it only has a mono speaker and mic like the R2H.
There are many more UMPCs coming out now but these are the major ones that you should consider.
UMPC - a new kind of PC
The past months I have closely watched a new kind of device being made available to the masses - the UMPC. UMPC is a short for Ultra Mobile PC. So what is a UMPC? Its not a PDA and its not a laptop. A PDA is too small and not a general purpose PC, and a laptop is often too big and cumbersome, although also a portable device. A UMPC is something in between. It has many similarities to a tablet PC, and I believe the touch screen is one of the most important features of it. Many also feel that it doesnt require an integrated keyboard - if you do add one it only becomes yet another small laptop.Most UMPCs today come with a 7" screen which is just right for this kind of device. The reason is simple to see from the number of scenarios you can use this form factor in. I will list a few here:
- In your sofa, web surfing or playing games
- In your home or office, calendar and contacts
- In your car, playing music and using it for navigation
- On vacation, kids can watch a dvd
- In a meeting, you can take notes, show documents or presentations
- In the bed, reading an ebook
- In your photobag, backup of memory cards and a teethered shooting device
- Anywhere, a telephone or video conferencing tool
These are just some examples of use. If you compare these to a pda or a general purpose laptop you will often see that they either dont have a big enough screen, not enough CPU power, or will just be too cumbersome to bring with you. The only real alternative is a tablet PC - and in my eyes a UMPC is just a small form factor tablet PC. If you do require a keyboard you can always connect one in a USB port or wirelessly through bluetooth.
One selling point of the UMPC is the battery life, which unfortunately up to now has not been too good. Recently there is a shift to more efficient components to make the battery life stretch to 5 hours on a normal 3-cell battery, which is quite good for such a device. These devices arent meant to be used continously like a work PC, but now and then, having the device in standby mode when not in use. A UMPC can often be slow to boot up, but bringing it back from standby is very quick according to user reviews.
The UMPC shown in this article is the Samsung Q1, which exist in 4 versions today, one with a Celeron 900 MHz, another with a Pentium M 1GHz, a third with a Via C7 CPU, and finally the original Celeron 900 MHz but with an SSD drive instead of a harddrive. I will comment the UMPC choices in another article, but my good eye is now fixed on the Samsung Q1 Pentium M edition.

My ongoing HTPC project
I have for some while been tinkering with a home built HTPC based on the mCubed hFX case which is a totally passive cooling system. By connecting heat pipes to CPU and GPU and leading the heat to two massive heatsinks on either side of the case you can effectively cool a pretty powerful CPU. Mine is using a Pentium M 740 (1,7 GHz) which the system keeps very cool. I also use a passive PSU that doesnt even get lukewarm simply because the total powerdraw of the system is very low. The end result is a dead silent PC! One very well suited for living rooms! The only thing humming in the device is a 3.5" harddrive mounted in a Vertical Silence. This drive does get very hot though and I really wish I could swap this with a flash based drive so I can get that movable part out of the equation. Will probably experiment some with a SATA CF adapter and a sandisk extreme card.The software that I was planning to use, Meedio Pro, was suddenly discontinued because the people who made it was "bought" by Yahoo. So I looked around and I am now using the open source project called MediaPortal. This works somewhat, although it has required quite a bit of tweaking to get everything up and running as I want. Especially with the XMLTV epg downloading. A part of me want to get Microsoft WinXP Media Center just to make things easier, but I have to check if I get the flexibility I want with it.
Go to my dedicated website - my htpc project - to get more information about how to build an amazing HTPC. :) Dont hesitate to mail me anytime with questions.
Its been a while...
The main photographic event lately has been wedding photography for some friends who married high up in the Norwegian mountains, by a big dam, the Sysen-dam. The scenery is spectactular (hoping to link a few shots here) and the wedding was very unusual in this regard. My 20D and the two main lenses, the 17-40mm f4 and 70-200mm f2.8L IS performed brilliantly and I got some nice shots that hopefully will make the bride and groom happy.
However, I have also learned a few things about wedding photography (this is my second), and that is that its hard to take control and arrange a good shoot. We had a plan to rig a neutral background using a couple of bedsheets so that I could get some nice potraits. And it worked fine for that except that the sheets were too thin making the woodwork shine its yellowish hue through it. Still I managed to isolate them fine in Photoshop later to replace the background. However, the biggest problem proved to be that everyone else in the party wanted to take pictures as well. This often made the bride and groom look in different directions and there was all sorts of distractions. It didnt get much better as people wanted all kinds of constellations of the family in the shots too. Since the bedsheets didnt look very nice (very wrinkled) and they hardly was wide enough to fill the frame everyone in the party probably has som terrible looking pictures on their compact cameras now. This again requires me to fix a lot more pictures than I had imagined (I was aiming for shots only with the bride and groom). So I guess the real issue now is just to limit the amount of pictures to work with.
Digitally there is some new ground to cover since I have problems making a believable backdrop when their feet are visible. It almost looks as if they are floating, and it requires some work "grounding" them in the shots. I have had some success by keeping the wriggly bedsheets where they are standing and I think I will go with that in the end, but fading upwards into a better looking background. A real challenge to get that professional edge.
During the shoot I used one single Canon 550EX flash which pointing up to the white ceiling which reflected a nice and diffuse light that worked fine for me to shoot at ISO 100 and 200. There is a hint of yellowish hue due to the wooden panels on the walls around but nothing bad. Will add a shot here later if I am allowed by the happy couple! :)

Canon 24-105mm f4L IS lens
Yup, this is the lens I am saving up for now. Previously I have been seriously thinking about getting the older 24-70mm f2.8L, but realize that this lens will be a typical carry around lens meaning that IS will be very handy too. So I'd rather loose one stop of light and gain 2-3 faster shutterspeed steps instead on this new lens. From the reviews this lens is very sharp wide open too, meaning that it would do excellently as a portrait lens too. It is also the perfect zoom for a full frame camera if I ever can afford the new Canon 5D camera. My 17-40mm is actually 27mm on my 1.6 crop 20D, and I have kinda gotten used to that being my "landscape" wideangle. On a fullframe the new lenses 24mm will be even better, and even more a typical walkaround lens. Just have to start saving up some money now! :)
New Wacom Intuos3 A5 (6x8) Tablet
Finally ordered myself a tablet that I have been wanting for a long time! If you do extensive work in Photoshop you will definitely benefit from one of these. Being able to do precise selections and paint masks with a pen is so much better than fiddling with the mouse and trying to move it the right way. The supplied pen is also pretty broad so its less of a strain to hold than a normal pencil. The pressure sensitivety works wonders in photoshop where you can do very small details by applying pressure. Especially important for masks. It also has a number of shortcut keys as well as two touch strips. I have mapped some of the buttons to common photoshop shortcuts such TAB for switching between full screen and normal, as well as undo and some others. Defaultly the left shortcuts are well specified with Alt, Ctrl, Shift and Space. That way you can do quite a lot of work without even touching the keyboard. The left touch strip I use for zooming, which works well, and the right I plan to map to pensize adjustments. I wont be using the supplied mouse since I already have a good bluetooth mouse with the Logitech Dinovo keyboard. The size of the tablet is just right, A6 was too small and A4 was too big imo, so the A5 (6x8) size fits me perfectly. Its definitely a digital photographers must have tool!

New LCD monitor, PC, and baby! :)
I guess the greatest news is becoming a father to a little baby girl! But since this is a blog about photography and related issues I wont go into the specs. :) Its everything a baby can be, except the special little thing that I'm the father. Couldnt be more happy, she is truly beautiful!
Well, I borrowed a Canon 380EX flash from my brother to try it out for some indoor baby shots, and must say I have changed my view on flash photography. When using a white ceiling as a reflector, its simple to take hand held ISO 100 shots at shutter 1/60. Got some very nice shots of mother and child with this simple setup and I guess a flash is whats in store next for my photography gear. Except that I spent all my savings on a new computer instead. :)
The Dell 20" has both VGA and DVI inputs, but from reviews and experience, the VGA input is not very good. I'm sure its ok, but once you experience this screen with a DVI signal you'll know what I mean. Since my old graphics board, a GeForce3 Ti500, only had a VGA output I had to look for another card. I had wanted to upgrade it anyway since I like playing games now and then. So the decision fell for the new 6600GT which is good value for money. Since i also wanted to leave the old AGP world for the new PCI-Express systems I also got a new motherboard and a new CPU. The motherboard, an Asus P5GD1, is a very nice package at a decent price, and the CPU, an Intel 530J 3.0 GHz is good enough performance. Why pay almost triple the money for something that is 0.6 GHz faster? I already had a 1GB matched pair of 512MB PC3200 memory sticks in my old system so they went over in the new system, doing what they were made for, dual rate running at 800 MHz!
The new computer system is very nice to work with, and more responsive than my old, absolutely excellent for photography editing in Photoshop. I have some more ideas for the system which I will comment here in a later blog. But for now, please come with questions or comments if you have em, I'm always happy for some feedback.

Canon 20D arrives !!!
I have not yet made any image tests to see how good the pictures are but my first trials show that its less noisy at ISO 800 and 1600, which was as expected. It also seems to cope better with keeping highlights and avoiding the abruptness of over exposure that was so common on the 10D. It focuses very quickly and works brilliantly with my 70-200 f2.8L IS. The improved focusing on f2.8 lenses is probably kicking in, but it also feels more responsive on my 17-40mm f4 lens. However, it still doesnt focus right on the wide end which makes me think that my lens have a defect. I'll have to check this out some more.
The user interface in the menus are clear and understandable. In some ways better than the 10D. Its also far more responsive than the 10D, especially when browsing images. Its also nice that I dont have to wait for it to finish writing everything in the buffer before I can access the menu or playback functions.
Its lighter and a tiny bit smaller, but it feels just right for my hands. I guess the 10D was a bit more comfortable to hold for people with long fingers, but I dont have that problem. If I should pick on something it would be that the mode dial feels cheaper and more plastic than before, its also a bit loose. The same thing goes for the CF slot which is also a bit loose. The joystick feels a little strange at first but I guess I will get used to it. Its surely a better way to move about images than the button/wheel combo on the 10D. Its also a very good for adjusting the focus points quickly.
The 20D shoots away like no other camera I have used. It feels like a small machinegun when it fires away at 5 shots a second. I actually had to turn the mode to single shot now more often simply because I ended up firing two shots instead of one. On the 10D its a bit slower so you could have the mode on multiple shot always.
The only thing I miss from the camera is a faster way to switch on and off the mirror lockup function since I use this more often. I also assume mirror lockup will be even more useful in the 20D since the mirror slap feels a bit more heavier than the 10D (although I have no proof for this).
All in all a very nice camera! Looking forward to take some real pictures with it.

IStockaholic
My wife, family and friends kept saying that they loved my pictures and that I should start showing them to the world instead of having them lying around on my computer and some of the better ones hanging on the walls. I never really thought about it that way and wondered if I should try to show them in a gallery or something. After some months I started reading more about online stock photography sites and came to like the idea of uploading a picture, having it sold over and over again and making some money. Digital photography is becoming increasingly an expensive hobby, and I saw that my "wish-list" at B&H was growing faster than I would ever be able to afford as I ventured into different styles of photography.
I started looking around and tried an online stock agency where I could upload a small version of the picture and if there was any sale the buyer would contact me through the agency. I would get paid according to the use, so a sale could mean anything between $50 to $1000. I uploaded some pictures, nothing spectacular, about 10 pictures, and waited... Nothing happened, not a single sale still. I got impatient and thought I'll have to try more places. After some time I found another place www.shutterpoint.com where I could upload a full JPG version and set the price as I wished. It had a system where people could rate your pictures too, and it was quite fun to watch which pictures was considered good. Eventually I saw that the site seemed overly focused on the rating thing, and everybody gave 9 or 10's out of kindness - even really bad grainy out of focus pictures got good ratings from some just because they had rated kindly to others. I realised that there was just too many bad pictures there for buyers to even find the good stuff - hence less sales. In the 5 months I have been there I've sold two pictures at $25 each. Not much but at least some.
Well, then I found another place: www.istockphoto.com which I immediately fell in love with. It had its own pricing policy depending on the size of the download and each image had to be approved by an image inspector. And from the quality I saw there I knew they were very picky about the quality. I got sales almost immediately after my first uploads and I was quite hooked, regulartly uploading and checking sales. It was really addictive - and still is. Now the only gripe I have about this place is the royalty I get - only 20% of the sale! Thats not much, especially when you think of the prices where a high res picture is sold for $1.50 - veeery cheap in other words. I can imagine this place as a big blessing for designers and it opens up a marked untouched before. Thats why it is a successful business too with an amazing number of downloads every hour. I immediately noticed the popularity of this place when one of my pictures was chosen "Image Of The Week" (IOTW) with the picture placed on the front page after login. This picture is now closing 200 downlads in under a month and is set to go for the most popular page soon (it actually was there before as one of the higher rated pictures with pure 5/5 ratings until I got one 3/5 rating from one guy that dropped me off the list).
At IStockPhoto we have an expression - IStockaholic - and I must confess I am one, visiting the site several times a day to see whats selling and talk in the community which is an excellent one. If you are a designer you will love this place - you cant get better stock photography for such low prices anywhere. If you are a photographer you have to decide if you feel a 20% cut is fair. Still you will be competing with some very fine photographers, some having over 90.000 downlowads by now. In time those cents will make you a dollar... :)

In focus?
So what you need is to know how you get everything in focus - from the little flower in the foreground to the snow-topped mountain in the background. As most of you know, stopping down the lens to e.g. f/22 will do the trick, but you are still not guaranteed to have what you want in focus. Its because the focus point needs to be correctly placed to get optimum depth of field (DOF). Normally this means you need to manually focus. The focus point you are looking for is called the Hyperfocal Distance and will ensure you the longest distance in focus. Naturally this changes based on the focal length (mm) and the f-stop. Fortunately this is pure math and no magic involved, and some people have been so nice to make an online tool for calculating the hyperfocal distance. Try the link below and enter focal length and f/stop, then press the Calculate DOF button. The Hyperfocal distance will be shown. You can enter this in the Focus Distance and see that it will show you the closest Near Depth you get with Infinite Far Depth (thats where the snow-topped mountain is).
http://www.dudak.baka.com/dofcalc.html
For my 17-40mm, while shooting at 17mm, if I focus at hyperfocal which is 0.525 meters, I get everything from 0.263 meters to infinite in focus! Now that should bring everything in focus. Of course you also need a tripod for shots at f/22 or your images will be all blurry from camera shake. No point in fuzzying with hyperfocal distance then.
Note however that many lenses have a sweet spot where they perform best, that means that image quality is generally best at this f stop. On most lenses this is around f/8 and f/11. So if my foreground starts at around 1 meter you dont need to shoot at f/22 to get everything sharp. Actually, if I shoot with my 17mm at f/11 at the focus distance of 1 meter I get everything from half a meter in front all the way to the back in focus.
I've ruined one too many shot by relying on autofocus so now I am keeping a table for reference so that I can quickly find the hyperfocal distance at each f-stop at the most used mm ranges (usually this is 17mm).

The dangers of f2.8 L glass
However, if you are coming from the average f4.5-5.6 world of consumer lenses, going to f2.8 kind of glass can make you do some mistakes. Once you have such a light sensitive lens its tempting to keep shooting at f2.8 without thinking about the concequences. Although I have been used to this aperture with my 100mm macro lens, the macro was often used in more planned shoots, closeups and tripod shots. The 70-200mm has IS and it works brilliantly handheld. However, if you are not careful, shooting at f2.8 can ruin your pictures. You have to remember that the Depth Of Field (DOF) is very shallow, which also means your focus has to be spot on. Fortunately this lens is both quick and accurate when it comes to focusing. However, there are many times I have focused at an area that was deep into the object I wanted i focus, effectively rendering the front part of the object unfocused. Unfortunately you cant see this on the LCD since everything looks alright there. You just have to think about it and make sure you focus at the foremost part (or actually a little bit further than that might work too).
Just so that you were warned! It takes practice to shoot at f2.8 and get good results. You especially need to think quickly when shooting on the move.

The Canon 70-200 f2.8 IS has arrived...
My first day of shooting and this lens immediately proves its worth. The kind of images I can take with this I could only dream of before. Its pin sharp even at 2.8 which enables a whole new kind of photography. My first impression out of the box the sheer weight of the thing. Its gonna take some muscles hand holding this for a long time. But on my first day out I must say its really not a problem. Just need a new strap for my camera, one that isnt so hard on the neck. The lens is at least built like a tank.
The zoom ring is a bit harder to turn in comparison to what I am used to, but that too is no real problem and I guess its good so that you dont accidentally turn it by holding the ring. However, I wished the same was true for the four buttons on the side. The IS, IS mode, AF/MF and AF range buttons are all very easy to switch accidentally. It mainly a problem when you pull it out of the bag and I have already turned off AF and IS by accident this way. Still no real problem once its up and you have checked the buttons.
The auto focus is amazingly quick on this lens too. It locks on fast and in AF servo mode it follows the target happily without a hitch. The IS is also very quick compared to what I was used to on the 75-300mm. Its also very silent. Just have to make sure I am full stocked with battery because it will empty the batteries faster (30% less time the manual states).
But the quality of the glass is amazing, combined with the IS I can handhold and shoot almost anything. Here are some pictures you can click on to see some from a first days shoot.
Tipa Awards
Sandisk got the storage media price, which I think is correct also. The Sandisk Ultra II cards are really good.
Other than that I see that Epson got all the prices related to printing, which might be right. Well until they realise the thing breaks down after half a year and the usage cost is way higher than anticipated. Ok, maybe I have been burned once, and base my feelings on that. But thats me. :-)
Sigma got the best consumer lens award, which might also be right. I dont know much about this lens but it sounds like a good spec and I guess its true. My only experience with Sigma was a 24mm that would never work right on my EOS 50e/Elan2, and many friends who can hear parts falling apart inside the lens. While this was some years ago, I hope Sigma has improved their build quality. Well this is an EX lens so its the top of the line for Sigma, and if you are on a budget I guess its a good alternative to the Canon 16-35mm or the 17-40mm.
