The sunday challenge = take a picture straight out of the camera,
either use a non-zoom or set your lens to 35 or 50mm only, camera to ISO100, and lets see something SOOC, no crop, no post pro, just like in the old days of film, or even use ISO100 film, mono or colour. The only post processing allowed will be your watermark-signature.. whatever you call it.
------------------------------------
I used a fixed 50 mm lens, manual exposure, ISO 100, 1/400, f 2,8. Gave away my analogue gear some 15 years ago, so the only option left was digital.
