IMPROVING YOUR MICROPHOTOGRAPHS
EO Hoffmann, M.D. LSUHSC, New Orleans, LA.
Most of us have important photographs that are not used because they are defective: too light, too dark, with spots, with folds with holes, need additional structures, have too many structures, etc. Improving these photographs is rather simple if you have a good program. In this page we present digitalized photographs improved electronically with Adobe Photoshop 5.5 - 7.0. Other similar programs may be used. See REFERENCES below.
