Way back when I made photographs on film I had a studio full of 5 big glowing light tables. Now with digital imaging, they are 5 big white tables. Now I am working on projects to see things very close. I am back to the light tables. I have designed a special studio. I have found that very close up macro images take on a strange phenomena when they are sharp throughout. They look like they exist as large as you print them. Something we are not used to seeing in close up images. To make all of my images sharp throughout I went back to my light tables and back to my engineering. My cameras are attached to motors that move them. The motor is attached to computers that control them and change the focus points in precise increments. Sometime as small as 1/100th of a millimeter. I make up to 50 exposures at different focal points of one object and then stitch them together in computer software. Much like making a panorama, but going vertically with focus.
