I'm going to be given some images taken on a Phase One P20 digital back, taken indoors where the colour temp on the P20, was left set on 'Daylight'. I will also be getting the colour temperature data from a Raw image (E-M1 camera) taken at the same time, under the same lighting conditions. It's at this point, that my brain has become 'frazzled' because I'm not too sure what the best way of converting the P20 files so they have the same colour temp as those from the E-M1 ... Do I just input (using PSP x10) the setting from the E-M1 image, into the 'box' showing the P20's colour temp, or the 'difference' between the two readings, or do something else? It's just that I'm seriously doubting my limited knowledge of this procedure! Sam.
