X3F or PNG: which should I use?

Use X3F for adjusting exposure and white balance with maximum latitude. Use PNG for screenshots, logos, text graphics and cut-outs. Keep in mind the main drawback of PNG: large files for photographs.

X3F is the RAW format of Sigma cameras with Foveon sensors, from the SD and DP series to the Quattro models. It stores the unprocessed sensor data for maximum editing latitude, so most apps can’t show it as a normal picture.
