Sigma Camera RAW Picture File
RAW photo format designed for Sigma cameras. It uses Foveon technology that extends the sensor's range of sensitivity, allowing you to record the maximum amount of information with each shot. It allows you to make subtle adjustments to the white balance, color, exposure, and other settings while preserving all of the details in the photo.
High Efficiency Image File
HEIF is a container that can be a single image or a sequence of images which makes it ideal for Apple's Live Photos. It is based on HEVC (High Efficiency Video Coding). The format is more convenient than the old JPEG mostly because it is twice smaller despite the fact that is has excellent quality. Therefore you can storage more images on your Apple device which is great. HEIF was developed in 2013 by MPEG (Moving Picture Experts Group) but has become popular only when Apple decided to replace JPEG with it in 2017. However, not so many programs are able to open it which is why you might need to convert it to another format.
