Contrast Enhancement

I am having some conflicts with the "Enhance Contrast" command in ImageJ and would like to know if anyone has insight into the two problems I am experiencing. I have written a simple macro to run thru a series of tiff images and enhance the contrast using normalization and then save each image as a jpeg. My two problems are as follows:
1) The macro saves each image successfully as a jpeg but when I go back and open them, only a few of them actually had the contrast enhanced, and some only had the contrast enhanced in a portion of the image down to a vertical line thru the image.
2) If I open one of the images in LabVIEW (one that was successfully enhanced in ImageJ), the image appears nearly inverted in greyscale, but not completely because if I invert the image greyscale, it still does not look correct.
Has anyone seen anything like this or have any ideas how to resolve either of these problems?


Thanks!
