X3F

Sigma Camera RAW Picture File

X3F is a raw image file format used by Sigma cameras, specifically those with Foveon X3 sensors. The format captures all the data from the sensor without any in-camera processing, allowing photographers to have maximum control over post-processing. The Foveon sensor is unique in that it captures full color information for each pixel by layering photodiodes, distinguishing it from other camera sensors.

JNG

JPEG Network Graphics

JNG (JPEG Network Graphics) is an image file format similar to PNG, but it uses JPEG compression for bitmaps and offers support for color and grayscale images with or without transparency. This format was designed to provide a simpler, more efficient method for transmitting images over the internet, and it allows for lossy compression to reduce file size without a significant loss in quality for certain types of images. However, JNG is not as widely supported as other more common image formats like JPEG and PNG.
