When I saw this challenge, I fell in love with it! I did have any what to shoot though.
I shot stuff all week, even today. I used 4 different cameras, of various calibers even a 35mm film. After all I acquired, I decided to go with a shot I made today.
Once all was said and done, going with this photograph, it was shot with my iPhone 6+
(Exif Data) iPhone 6+, f/2.2, 1/20th a sec, ISO 80, 29mm
