Hi, I have some pictures taken by a CCD camera that are 12-bit TIFF images. Photoshop (7.0) - even tough it opens them without an error message - obviously cannot handle these properly as all images appear totally black. However, AFAIK Photoshop *can* handle 16-bit TIFF images, so what I want to do is convert the 12-bit TIFF images to 16-bit TIFF images. Conversion to 8-bit TIFF images is not an option because the images are supposed to be used for quantitative evalutations (intensity values) and I do not want to lose any information. Hence, my question is: Which tool can convert 12-bit TIFF images to 16-bit TIFF images (or which tool allows opening 12-bit TIFF images correctly and saving as 16-bit TIFF images)? Peter
