dude that is amazingly crisp. what were you shooting with?
Hand held Canon R3, Canon 100L IS Macro, manual focus, ISO 320@200, F9.0. Neutral lighting due to moderate overcast conditions helped a whole lot while I was trying to compose the shot because I didn't have to deal with high/low contrast. The lizard was square and parallel with the plane of the lens over most of the length of his body, so all I had to do was get nearly focused on his eyes and then gradually rocked back and forth until I thought it looked like it was focused correctly, all while trying not to spook the little fella from launching himself at my rig. In other words, I got damn lucky.
Oh, forgot to mention in PS, I used a bit of clarity, noise reduction, and a smidgin of vibrance and saturation and unsharp mask to tidy things up.
