I have a batch of .tif negative grayscale image files which I want to read on Matlab as a positive file. I converted the negatives into positives with Photoshop but then Matlab said the files got "unknown tags". Does anyone know how I can convert negative images into Matlab-compatible positive ones?

Either use imcomplement(), or do simple additive inversion.
