A week ago at our camera club we watched a Harold Davis video on flower photography, and editing with LAB color in Photoshop was mentioned. I had watched many of his videos several years ago and had been inspired to buy a lightbox, which I use often when I shoot flowers. But I had not played with LAB color since that time. So I was inspired to try this editing technique once more with photos I had already taken. Basically, I used color channels to invert colors and blend modes to apply to the regular image. This is definitely not my usual style, but it was fun to do.

It seems as if there is fire within it. Spectacular!
