Hi Dr. Craft, John Harwell won't be in until a little later today, but I wanted to be sure the problem wasn't with the exported tiff images. Have you tried viewing the exported tiff images with a viewer other than Caret (e.g., PhotoShop)? Which operating system are you using? Many Linux distributions have a graphics viewing utility named "gimp"; I'm not sure what the corresponding utility would be for MacOSX. If you have viewed the exported tiff images in another graphics software package, and you don't see the resolution problem in that viewer, then you have made sure the problem doesn't lie with the tiff images themselves.
One thing worth trying is to export them in another file format (e.g., jpg). Try converting just one slice, and see how it looks in Caret.
