I try to use 32bit exr files for displacement whenever possible, as generated by my texturing programs.
I am wondering if the following make sense. If one has a very high pixel size 8bit image that will be resized by 75% before use as a displacement map, would it be beneficial to convert it to 32bit before resizing and then exporting as an exr?
Would the data from the original larger pixel size image be retained but with substantial file size and memory savings?
