Juan,
After using ImageIntegration on a set of debayered Canon 5D2 files, I save the file using "32-bit unsigned integer" rather than the default "32-bit floating point". The file created from ImageIntegration looks great; however, after saving to "32-bit unsigned integer" and reopening the saved file, I've lost almost all the data. It becomes a black image even when using the aggressive auto STF. If you need an example, please let me know.
