YMCK

The acronym photo developers use for Yellow (Y), Magenta (M), Cyan (C) and Density (K). I am no expert on this matter so I would really appreciate any input from anyone as to how I can better this experiment. This is an attempt to get better photo prints from any regular photo developer. Prior to this, I had to deal with overly dark prints (which show little or no stars) or overly bright prints (which look as if the sky underwent a really bad bleaching experience). My thanks to Kelvin & Patrick of OIS Konica for trusting me to twiddle with the photolab equipment.

Colour and contrast are subject to individual visual preferences. No scientific measure was used to calibrate false colour imaging in this experiment.
