Here is something that can have a huge impact on how Canon shooters will aces their files. Up till now, they were dependant on Canon’s proprietary raw format – CR2. But a recent proof of concept from Magic Lantern shows that Canon bodies can shoot DNG right inside the camera.
As a short recap, each camera maker has their own closed proprietary format in which the provide RAW files. Canon uses CR2, Nikon has NEF, Sony uses ARW and so on. The thing is that each of those formats are proprietary. Adobe DNG, on the other hand is open, light and releases software makers from their dependency on camera makers.
Magic Lantern used “a1ex” (who seems to be very active in ML development) released a proof of concept snippet of code that makes Canon cameras save DNG files rather than CR2 files.
