Sorry for the totally unrelated thread jack - but hey, you said you didn't mind pictures Puck!!
Here are some examples of what you can do with macro shots. I went browsing through my files and found some old pictures. Being "old", these were taken with now outdated cameras depending on your budget and who you ask. For all of the pictures you see in my growing thread, those are using a 7.1 MP camera which I'm sure theres a lot of peolpe who would consider that outdated now. The pictures below however were from cameras less than 5MP. During the part of my career I took these photos from I was using a 3MP and a 5MP. I went back as far as I could so I could use the least resoultion photos to show my point even better.
I beleive these are fom the 3MP. Which was nothing more than one of those Kodak point and shoot's that you can scoop up on sale for not a lot of money.
As for the subjects. I mentioned above, not only do they move around - but most were very small. Pictures one and two are of a species that is only about 2", 2.5". Not only do you want to take the picture, but your also looking to capture the fine detail of the hairs and Carinae (the bumps) on the head and the other parts of the body. Beleive it or not - their not only useful to the scorpions but also to reasearchers as they can (help) identify species, sub-species and local variations.
The last picture is of a species which full grown is <2", however this specimen was only about 1" at the time. Thats a 40 dram vial it's living in and as you can see she had more floor space than most college kids do in their dorms! Keep in mind a typical medicine bottle is like 15 drams maybe? Thats a tiny container realitivly speaking. Because of how tall the vial was though I couldn't get close enough to shoot the subject well, but you can see how good the mottling of the exoskeleton was captured. This right here is a truely beautiful animal - sad thing is they are TINY and can and do kill a lot of folks each year.
Anyone with questions at all on picture taking, feel free to contact me - as you can see I've photographed the tiniest of subjects!
