[QUOTE="SuperDave, post: 2425752, member: 1892"]Don't get me wrong; I'm utterly fascinated by it. For our purposes, given the relatively uncomplicated circumstance of coins with their lower relief, it'd be easy to rig a hemispherical LED array and in conjunction with remote shooting software script the entire shooting and lighting sequence into a one-click affair. Given the 45-50mm diameter of duplicating lenses, you could come closer to true vertical lighting than their full-frame lens setup. Then, rather than requiring the viewer to download and implement a software solution, you just pick and choose among the shots to create an HDR composite 2D image of the coin with no lighting weaknesses. Instant forum-postable, gradable imagery. :) Another potential usage is in conjunction with rmpsrpms' 3D imaging/.gif technique. Mount the camera - something like a Canon SL1, which barely exceeds 14 ounces - on a ball mount/arm, and vary camera position just like you do the lighting. That would require an open lighting framework rather than the matte black enclosed hemisphere I'm envisioning from above, therefore stricter environmental lighting control, but the result would be imagery of sufficient resolution to identify detail features without additional magnification. [B]That'd[/B] require me to go to 32GB of RAM in my computer, I think. [I]Serious[/I] CPU crunching required. :) You gotta see this, [USER=31773]@rmpsrpms[/USER].[/QUOTE]
