In a forum thread somewhere, somebody asked about resolution in distant focus and that tickled me into writing this article on the influence of the environment on long tele work. I have taken several pictures of distant blobs at long focal lengths, so clearly I am the undisputed expert and my words should be taken as gospel (and if you believe that, I have several renowned landmarks for immediate sale as well).

Disclaimer: I'm not a scientist. Also, some of the science in this post has been simplified.

Update: Phase 2 concluded. During testing for phase 2 it became clear that the original tests for the eneloops was faulty, and that test has been redone, yielding radically different results.

When laying out photo books or posters, it's sometimes tricky to find a good layout that works. Here's some examples, both with gaps between the images as without.

About a year ago I tested the power usage of the E-510, which was interesting to me because I was planning a trip to africa at the time where every drop of battery juice counted. Hawing switched to the E-3 since, I've decided to run the same tests for the heavier camera.

While perhaps a bit esoteric for some, knowing how much power your camera actually uses in different configurations can be essential in stuations where you need to get the most out of your battery. Minimizing power usage can also speed up focussing with some lenses.
