RW2 to CG4 Conversion: FAQ

What are RW2 files?

RW2 is a file format associated with RAW images shot using a Panasonic Lumix camera. Unlike compressed formats such as JPG and PNG, RAW images cannot be used as such but need to pass through post-processing. Professional photographers favor RAW images because they allow them to have more freedom to adjust the image and shape it the way they like. However, setting your Panasonic Lumix camera to shoot RW2 images might not be a good idea if you are an amateur photographer and do not have some knowledge about how to use an advanced image editing program.

What are CG4 files?

CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs.
