   Saving and Loading Floating Point images on mac
  Hi,I need to load floating point textures from disk for use in an openGL floating point texture for the first time and I have no Idea where to start. First of all I would like to save it from Photoshop (I am on a mac) or convert it afterwards without loosing precision. What format would be most suited for that? Also what c++ lib could load it for me? Maybe freeImage? Also when I want to create my texture in Photoshop, is it correct, that I have to go to Image > Mode and make it 16 or 32 bit channel to make it work?I hope someone can give me some hints on that topic!Thanks!   
  You can use OpenEXR to store 16 or 32 bit float data.   ;  hey, thats exactly what I did.- FreeImage handles them very well too!
