ตัวแปลงไฟล์ออนไลน์ฟรี X3F เป็น RB

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.

Was developed for the first mass-produced e-book reader – Rocket eBook. The format is written in Ruby. RB files are containers holding the entire content for a Rocket eBook device. It has DRM protection capability which is not used in the books published at present due to the format’s lack of popularity.
