Our group of PhotoScan users would appreciate it if TIFF images using the LogLuv encoding could be imported into PhotoScan. The LogLuv encoding is a high-dynamic range encoding using four bytes per RGB pixel. PhotoScan is already using the libtiff library to perform importing of TIFF images, and libtiff includes support for LogLuv, so the Agisoft developers should be able to add support for the LogLuv encoding with very little additional effort.
