Looks wonderful. Well done. I was unable to fully grasp the significance of two liths. Can you help me hereThanks

The TP5+ is a transluscent material, not so much as a regular transparency, but close. I made four of these prints two were too thin and too were too dense for the light frame I made. The two thinner prints stacked atop each other gave the best density. Basically, there is the plexiglass front, the mat, the two prints, a spacer, a sheet of white plexi, a spacer, and then the light board. The frame for the whole thing is 3 3/4" thick, which isn't bad. I couldn't go thinner because there wasn't enough space for good diffusion. Even here in this crappy image, you can see the difference in the 5400K lights and the super warm 3100K bulbs in the clouds. There is still a bit of a 3D effect that won't come across on the monitor. Maybe later I'll put something up on the presentation forum. Now with LED's, if you have any sort of transluscent material there are many possibilites. The big frames are maybe $50, lots of things can be culled, wall warts from Goodwill, recycled resistors, wood, paint.. The actual component bulbs are .75 each. Mats and plexi are the main expense. Anyway, thanks for looking.

Rich , could you please explain what is the difference printing with cold and hot light ? Yes I see the 3d da vinci effect on clouds and less at orchids. If I take an ordinary bw negative , do hot lights gives the 3d on print ?I saw two books , one printed at germany and other was pirate. The pirate one printed hot reddish orange colored portraits and I asked myself , is it really leica or kodak lens I use or the color of print gives that 3d effect or the color of the light source at print- 3100 bulb - gives the 3d or the kelvin of the light at environment or the diffision , transmittance or reflectance of the optical glass or 3d optical transfer function where in one photograph there are two psf per dot interacted and increased the resolution.

Thanks Rich I hadn't realised that the material was transparent nor how much work went into constructing this effect
