    Hello Group: I have a hyperspectral image of an object, and an image of white reference and an image of "dark". I want to calculate reflectance by taking each band in the hyperspectral image, subtract dark image, and then divide it by (white-dark) image. How do I do this operation in ENVi or IDL? Thanks. Jeyam.

    It sounds like you could use the Band Math tool in ENVI.
