MRW to CAL Conversion: FAQ

What are MRW files?

MRW is a RAW image format used by some Minolta camera models. Professional photographers often prefer to shoot in RAW mode because this offers a significant increase in image quality and brightness. With RAW images it also becomes easier to adjust aspects such as under or overexposure, white balance and colour space. Using a RAW format, however, requires some knowledge regarding image correction using an advance editing program. So while professionals might find it highly convenient, for amateurs RAW images can be difficult to handle, as well as store and transfer.

What are CAL files?
