- Cadcorp Map Express – check the bottom of the page for downloads; also opens CAD files directly

- Monteverdi (Orfeo ToolBox) – this program does the best job at histogram stretching (i.e. color balancing) 16-bit imagery and then exporting to a GeoTIFF
- Quantum GIS (QGIS) – this is an advanced program that can do more than open imagery files; it also works on Mac operating systems! Mac users will need to install QGIS and GDAL from here; and NumPy and Matplotlib from here. For directions opening an imagery with QGIS, see this video.
