First of all, let me start off by saying that the color of the eyes is natural, and that is the way it came out of the camera (see original photo below). The green is made even more apparent by the fact that I took this photo on a green pillowcase. I honestly don't know why the eyes of jumpers show up as different colors, but they are beautiful nonetheless.
I was planning on taking it easy inside today as Friday I was attacked by ants and now my left foot is swollen, covered in sores, and itchy as hell. But I got bored this afternoon and headed out to the nearby field to see if I could find any bugs. Initially, I didn't have much luck, but as I was about to leave, this female jumper perched on a large blade of grass caught my eye. I couldn't believe she was a jumping spider at first due to her enormous size. I'm sure I've seen bigger ones, but she was at least 20mm in body size, she was huge!
I coaxed her into a zip-loc as it was getting dark and headed home to photograph. I set her (and some leaves I had collected) on a green pillowcase. I used a small bike light as a focus assistant (basically a spotlight so I could see through the viewfinder). I took all the photos I wanted and then released exactly where I had found her.
This photo (a crop from the image below) was taken with my usual 28mm (at f/8) reversed on a few extension tubes, which works out to be somewhere between 4:1 and 5:1. I really wish I had my bellows with me so I could have taken this photo at 10:1 as she was really being cooperative with all the picture taking.
