I've always been semi-intrested in macro photography. I probably won't ever get too deep into it, as it seems too meticulous, but it can leave some stunning results from this mini world.
I've heard of lens reversing near the beginning of my journey of photography years ago. Problem was, I just never had the correct gear to do it. But I just realized, now I do!
Reading around some quick guide online, I learn that I should stop down my main lens, keep the reversed lens wide open, if I divide the focal length of my main lens by the reversed lens, I can figure out the magnification, and to also use a flash.
So, I throw my 18-105mm Nikon lens on my D200 and zoom into 105mm, stop down to f/16, pop open the built in flash, hand hold my reversed 50mm 1.8 AI-S (wide open) on the front of my lens (reversed lens @ closest focusing distance), hold it all very close to something (inch or three away), let the AF figure it out and BAM. Picture. Holy crap.
(theoretically this is 2.1:1 magnification)

I really love that keyboard picture... so cool!
Thanks all for reading this. It was fun :P
