Use Photographic Stretch to enhance the color of a true-color input image to produce an RGB image that corresponds well to the response of the human eye. These results look more like realistic color photos. The bands of the true-color input image are nonlinearly scaled then co-added to produce this stretch.

1. From the Toolbox, select Transform > Photographic Stretch. The RGB Photographic Stretch Input Bands dialog appears.
2. Select one band each for the R, G, and B fields, then click OK. The Photographic Stretch Parameters dialog appears.
3. To spatially subset your data, click Spatial Subset.
4. Click OK. The RGB Photographic Stretch Parameters dialog appears.
5. Select whether to output the result to File or Memory.
6. If the output is to a file, provide a filename in the Enter Output Filename field.
7. Click OK.
