How I Create My Images.

Scurry64: Color looks real close. I edit it first removing too much orange on cents if they are to gold colored. After reducing with the "Hue/Saturation" choice, then I remove some of the hue by reducing the color to brown the coin a bit (instead of gold colored). Then I add color with the "color balance" starting with red, magenta and then yellow to get the final color. If a coin is too dark, I use the "hue/saturation" on the top line to adjust it with a bit of yellow to enhance the darken color, then contrast it to get the desired color. (Looks like I need to make up a thread for this?)

Why two bulbs? When you use two light sources, you create light on both sides of the devices and sometimes makes things appear that aren't really there. On a scope or a full image setup? Too much light is a disadvantage as it prevents light and shadow. Too much light/darkness hides varieties we really want to see the separation.
I experimented with a ring light for taking images under a microscope and the multiple light sources enhanced to much of the fields.

Note there is darkness around the devices, but not real helpful. Lowering the light and reducing the number of light sources helps the fields stay in the background:

Real nice photos coop!
