RawDevJS – JavaScript raw image developer
- canadaduane 10y agoCan someone explain what this is?
- cooper12 10y agoSo images from most cameras are stored in the JPEG format, and that is after all the in-camera processing is done to it. (what the camera sees has to be corrected for stuff like lens distortion, color as a human would see it, and has stuff like sharpening applied) Two major problems with this is that JPEG is a lossy format, and the original image that was captured by the camera had a lot more information that can be used. (for example raw images are often able to be used to save blown out highlights or shadows) So professional cameras offer a "raw" capturing mode which saves that information in its own format like DNG. (which itself is pretty much TIFF + metadata) These formats aren't widely supported outside of image editors though and require manual processing before they look good. RawDevJS [0] seems to be a browser-based editor for that and the author also released other repositories such as a tool that renders DNG in the browser and a command-line converter.

- bergos 10y agoThanks cooper12! Very well explained. I would be happy if somebody would join the development team. I'm very busy with other projects, but if you have a look at the further ideas I have already collected [1] this tool could be very useful for many people, not only users of DSLR cameras.
