title: working with tiff files in python
body: <p>First are tiff's grayscale? As I understand how tiff's work they can accept floating point numbers as most other image types cannot. I am attempting to do a linear interpolation for smooth coloring and need to put the floating point rgb array into this tiff image. What is the proper way to do this? As of right now I am using PIL and two for loops to iterate over the width and height of the new created tiff to put the pixels there and then converting to CMYK format, but when opening in a program such as Ifran it shows an apparently grayscale image and it doesnt look like the full image got generated, as in only half of it appears in the full image.</p>
