Just normalize all slices with enhanc contrast

no additional macro info necessary, just this line:


run("Enhance Contrast", "saturated=0.5 normalize normalize_all");



Best

As I am primarily interested in the movement and not in the absolute intensity, I tried to adjust B&C for every image in the stack so that I could compile a movie file. However, with the macro I used, I just modify the images once, but the saved correction is only adjusted for the last image. Is there a way to correct and save every single image of a stack?
