Why not start one yourself entitled something like:
Photographing Fossils - Tips and Tricks
and then a short post saying you are learning to photograph your finds and are hoping to solicit advice in a thread. I am sure Kevin will give some advice as well as a number of others that have struggled getting detail. If it gets enough attention, we can make it a sticky that stays at the top. You might include a note, requesting that the information poster always include a Tip title (through the Go Advanced button) to help keep topics easy to find.
What feature of the 510 made you give up your "deal" to go with the higher end camera?

Seriously though I haven't had time to touch the camera since the first day I got it, still busy tommorrow, hoping to spend time with my camera Thursday and hoping the weather co-operates, too much rain!
but never could focus a camera easily so good autofocus is one of my main criteria (remote firing and low light will be on my must have list next time). The other really helpful thing is the anti-shake stabalization for videos. We are interested in different targets though so I would think sharp macro auto focus would lead the list. DO NOT look at the digital zoom or consider it as part of your target list. OPTICAL zoom is what should interest you most and will produce a true magnification. IMO Digital zoom is software and pretty much worthless in a camera (helpful in printing but I use a computer program for that, not when taking the original picture).
but one accessory I cannot live without is a tripod. The difference in my pictures is dramatic with and without. They make a variety of very small ones you can use in the field. Some have very bendable legs (not surprisingly called an octopus) but I like the short metal ones with individually expendable legs for stability.
Sorry, there seems to be some sort of error on the page. I didn't get the first few, until fig. 3 came up, which was the one I found interesting.
I'll go through the pics. I have and see if there are any showing the rest of the rock better. If not I'll have to wait for a little sunlight to get a better shot.
