In anticipation of writing about the "droplets on the legs" story I wanted to go play with the calibrated RAC images of Holy Cow. But the RDRs are 32-bit images, and I'm not sure how to open them. NASAView can at least open and display them, but it applies an automatic contrast stretch (I think) and only permits output as 8-bit GIFs or JPEGs. In an ideal world I'd like to be able to convert them all to 16-bit images in any format that Photoshop can read, using a common conversion from 32 to 16 bits -- does anybody have any advice?
Here is a sample image (the first, from sol 5). Text header is at the beginning of the file. I would be quite happy to track down and provide all the .IMG files for the Holy Cow images that have been released to date to anyone who wants to play with them.
