Back in the old days black and white was the " photographers : choice, colour was for happy snappers. B/W users spent hours in darkened rooms mixing wonderful concoctions of chemicals,. On the other hand colour users took their films to the chemist, or sent them away for processing. Colour users were satisfied with En Prints or used the dreaded positive film to produce scores of slides which they insisted dragging out on every occasion, visitors normally lasted ten minutes and then died of boredom. No, photographers worked in B/W, colour was for snappers .......well I did say I was a snob. Anyway times change, Adopting the Fuji system I accidentally started looking at colour, amazing, it's rather good. It can't be that difficult, I find terms such as seeing monochrome or colour totally meaningless, I see a subject and I reckon any subject worth photographing will work in either. Anyway, I have a question. I use a 27" 5000K Mac Retina display, is it any use buying a calibrator, at the moment I am finding getting colours to print properly a rather hit and miss. affair. I think my monitor has only a brightness control..... Please help.
