djwalters Posted February 11, 2018 Posted February 11, 2018 Has anyone from the Affinity team looked into the extra embedded image in CR2 files when Dual Pixel Raw is enabled on select Canon Cameras? In DPP, one can already use this to fine-tune focus. However, recently some folks (FastRAWViewer) have tried to split the normal 'A' image (summed data from the dual photo-diodes) and 'B' image (single photo-diode), which can be used in photo stacking or HDR merging. The result seems to provide ~1EV of dynamic range improvement from a single "exposure", with the caveat that the image isn't 100% the same focus at extreme depths due to the parallax effect from the split photo diode locations.
