After some fiddling around, I have found out that even if I convert the stacked RGB to 8 bit grayscale before trying the Bandpass filter, I get the Out of Memory message. I had overlooked that, because the alert window is covered by any new image window which is created.
If I use 8bit gray images, and export as tifs, I get a grayscale image, not just black. But regardless which parameters I use, the resulting images are all the same. Meaning the Bandpass Filter operation is not performed at all, due to memory problems.
So I think it is a problem of memory management, maybe specific for the Mac. When I get back home, I'll try it on Windows.
So long.
