Good morning guys, welcome to my first thread on the forum. I primarily work with colour using Ilford 2000 paper and what ever RA4 chemicals I can get my hands on. Currently I am using the SpeediBrew RA4 kit which although cheap is exhausted quickly. As a lot of my images are from a Holga, I usually work on a small print 6" until I get the right colour and dmax from the print. What I have noticed though is when I come to do an enlargement I need to increase the yellow filtering. I cant understand how the colour filtering should change depending on the size of the enlargement. I am keeping the light hiting the paper the same and I am keeping the exposure time the same. Chemicals are pretty fresh temperature is at 35c for 45 seconds before 10 seconds fix then 45 seconds BLIX. Exposure time is 5.5 seconds, I am using a Meopta Magnifax enlarger and putting the paper through a Nova processor. Oh and the lens is a Schneider Componon. Anyone else experience this?
