It's a little too wide, but rather than resize why not just crop a bit off the sides?
It does look good, and the technique is a way to keep the camera away from hot or corrosive zones.

Hello,
I found that using a stand for the camera can make a large difference as I seem to always be shaking, however small.
Some of the photo's I have uploaded are a disgrace so I am not lecturing.

Shaking is a problem. Thats why when taking these photos I take as many as I can and then chose the on that is the lest blurry.
I resized the pictures N_I. I never thought about keeping it away from corrosive materials because honestly this is the closest I was ever able to get
the camera to an object and still get a picture. For me its been a battle to get as close as I can and still retain clearity.

Stting up a tripod for every closeup can be a pain, but acceptable sharpness at 1/50 sec is possible.
Pressing the camera very firmly (to the pain threshold) to one's head so that the camera can't move without the head moving is an old trick.
Using the highest possible ISO, aperture and shutter speed often works wonders too. . .
Some DSLRs have a MUP (mirror up) setting and this is great off a tripod---using MUP handheld takes practice but it gives exceptional results.

I have changed my write-up about photography quite a lot. Some obvious things are added, the discussion, started by Vulture about aperture size has
been taken into account and a section is added on how to deal with high contrasts. I hope it even more helps people making good chemistry-related

Interesting read!
About the DOF discussion some posts earlier...
DOF can also be increased artificially in a process called focus-stacking. The process resembles HDR technique, only that photos are taken and
combined with different point of focus, instead of exposures. The program that I use for this is PhotoAcute studio, which also contains a large number
of predefined lens profiles, making things even more easy. Supposedly this feature will also available in PS CS4.
I usually shoot with drive set to single shot, and AF off, then just turn the focus ring and take like 3-5 pictures while moving the focal plane
through the subject.
It is like shooting with a pin-hole lens, but than sharp as hell! The results can look static for some compositions though...
Wonderfull exmple of focus stack use: (Although not chemistry related)

I thought you might enjoy this site Woelen. You may have seen it before but it contains quite a few very nicely done pictures of chemistry related
topics.

Various dyes transilluminated at 300nm
I had a good "science day". RGB ! I was looking for a third "yellow" to give
red, but didn't have anything that filled-the-bill on the shelf.
