Source Victoria, a super cool band from Phoenix, asked me to come to their studio sessions. I definitely didn’t turn that one down. Not only did I shoot tons of photos of them making music, but I took some interesting shots with 2x, 10x, and 18x filters for my lenses. Depending on the zoom, I could generate a cool vignette around the sides. This was not created in post production.
The settings on my camera were pretty insane since there wasn’t much light in the studio. Alas, I think that Nikon did a good job.
So, all you need to do is find the correct diameter of lens you need, screw that thing on, and have a field day. The vignette is interesting and doesn't bother me, plus you're creating something that had restrictions. Have fun.
