Out of the box the Analyser Pro has the settings for Ilford MG IV. If you use a different paper YOU have to put the data into each channel. You can do this with the starting recommendations or do a calibration test. The recommendations are based on Ilford below the lens filters. I have a colour head so had to do a calibration test to use the filters in the head. Once calibrated the Analyser Pro gets me to a very good print very quickly. I don't agree that it eliminates test prints like their advertising says but it does save a lot of time in the darkroom.
