Hi Robert,

ImageJ can import 32-bit images; it opens them as 32-bit floating point
(which results in some loss of accuracy for high pixel values). You can
then apply a color LUT of your choice or any other processing you like.

Use File>Import>Raw or the corresponding IJ.run command (Use the Macro
Recorder in 'Java' mode).
