Taken with my HTC Radar. No adjustments, cropping or any other effects were used except using Thumba photo editor and clicking on 'black and white.'
I am confused as how dpi translates into pixels, but the picture is in approximately 5x7 format and the picture is fairly small. Heck it's only 38 kilobytes.
Edit:
Also, no I didn't just walk up to somebody's eye and take the picture
It was kind of a hard shot to get the lighting right. The first shot I am submitting for the contest, the second shot is just for fun, since I didn't know which one to submit at first. The second image was cropped a little.
