I've been to Leeds music festival three or four times now. I usually just take snaps with my iPhone but one year I took my DSLR and a 50mm lens. I took some shots of my wife, and she repaid the compliment by taking a photograph of me. I processed the photos on my iPad using Snapseed as an experiment and I really liked the results, especially after I converted them to black and white.
I hope you like them too!
