I made some duplicates picture (of negatives) with my digital camera using a bellows and a repro-dia.
The image is obviously in a negative format but in RAW.
Is the invertion function exists in Lightroom or I have to buy Photoshop or to find another software who can do this? I tried to invert the curve from the development in Lightroom but it does not work.
EDIT: It does not work becaue it is not only the inversion but also the orange filter to correct (which become cyan on the inverted picture).
