Is this a close-up of a small rock or further away of a larger rock so that it will all fit in the picture frame?
We need to see something we know along side to show scale. Either a bowling ball or golf ball, whichever fits.
Also, most people don't realize that they have a macro setting on their digital camera that lets them get the lens as close as 1"-3".
Extreme close-ups would help too.
Thanks
