pixel intensity values significantly lower when using your own flatfield and darkfield images

[ghost]

Hi not exactly sure why, but when i use my own images for flatfield and darkfield correction, pixel intensity values are much lower. when i have basic perform its own estimate, intensity values are near the same range as the original image.

Hi, Peter. Basicpy should perform similar to basic. Could you give me how you set lambda-flat and -dark in both basic and basicpy. Could you also try to use flatfield correction only (ignore the darkfield) Peter Maye ***@***.***> schrieb am Fr. 13. Sept. 2024 um 18:09:

I figured out what was going on sort of. if i do flatfield correction with numpy then i would take my flatfield image and divide it by its np.max value to normalize and generate a much smaller number for division. Apparently Basic was not doing this and so my pixel numbers were all much smaller.
