This list of resources is all about acquring and processing aerial imagery. It's generally broken up in three ways: how to go about this in Photoshop/GIMP, using command-line tools, or in GIS software, depending what's most comfortable to you. Often these tools can be used in conjunction with each other.

Avenza Geographic Imager - Expensive but excellent plugin. Allows you to much of what GDAL does (plus things it can't) and preserve geographic metadata. http://www.avenza.com/geographic-imager
-
Without Geographic Imager, you need GDAL tools if you want to preserve geographic metadata:
Dump metadata from a file before messing with it in Photoshop
listgeo -no_norm original.tif > original.geo
Add the metadata back after saving back out
geotifcp -g original.geo modified.tif modified_geotiff.tif
```
