MDC to CG4 Conversion: FAQ

What are MDC files?

MDC (Minolta Digital Camera) is an image format associated with shooting in RAW mode with Minolta cameras. RAW images are often preferred by professional photographers because they allow the camera to capture a wider array of details than other compressed formats, such as JPEG or PNG. For amateurs, however, shooting in RAW mode might pose significant problems related to digital post-processing using an advanced editing software. Moreover, RAW images tend to be very large in size, and are difficult to store and transfer.

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.
