Sony software "ARQ" support #185

Open heckflosse opened 5 years ago

LebedevRI commented 5 years ago

There is not a single *.ARQ raw on RPU. Which camera is that?

heckflosse commented 5 years ago

It's not a native camera format. It's the format the sony software creates (not in camera) when you combine 4 pixelshift ARW files.

Camera is Sony 7R III

@LebedevRI I forgot to mention: I don't mean that kind of support, that gives me a combined image from the ARQ file as PixelShift2DNG does. To use RawSpeed in RT we need to get the 4 frames out of the ARQ file as in this code: https://github.com/Beep6581/RawTherapee/blob/dev/rtengine/dcraw.cc#L2527

shot_select is the number of the frame [0;3]

That is how i understood it, yes.

Up, any clue who has appropriate camera and can help contribute nessesary sample? I think @cryptomilk had some similar camera?

cryptomilk commented 5 years ago

I don't have that camera but I posted in a Sony A7R3 forum and asked for a shot. If we don't get it I could check a store it and ask if I could take a picture with the camera.

LebedevRI commented 5 years ago

Samples received by RPU, reviewed&accepted, thanks to whoever contributed them and to @cryptomilk for leading the search!

What is the state of the Sony ARQ file support? I can supply Sony A7RIV files that are gathered from 4 or 16 photos.
