sRAW/mRAW
« on: April 18, 2018, 01:52:38 am »
Hi

I just learned that DXO Photolab does not process Canon sRAW/mRAW
i
As I have many such images what would be the workflow I should use.

I do have Adobe Lightroom  I use Canon 70D

Thanks so much

Ted

Maybie use DNG Convert and open this DNG  with DPL.

For a while I shot mRAW with my Canon until I found that I could not process them with Optics Pro (this was some years ago). I think I tried using the Adobe dng converter and processed those images but I am not sure if that worked or not.

I liked OP so much that I stopped using the mRAW setting rather than give up OP.

Hi tedweitz,

 The mRAW and sRAW are compressed format ( regardless the extension in all cases are .CR2 ), that is why PL doesn't take care of them.
You can convert them to TIFF or JPG in a 3rd party app ( a lot of free app also able to do it ). Keep the resolution as big as possible. The Canon free DPP4 can do it also.
The handicap of all conversion is the reduced resolution. Here are my EOS-7D facts:

RAW original Image Size   5184x3456 ( after JPG conversion same size )
JPG original Image Size   5184x3456 ( made by camera L resolution )
mRAW original Image Size   3888x2592 ( after JPG conversion same size )
sRAW original Image Size   2592x1728 ( after JPG conversion same size )

After conversion to JPG, PL is able to open, but with limited tools availability.

The best option is probably to use Canon Digital Photo Professional (DPP) version 4, or version 3 if your computer is too old.  You can download the latest versions and the lens modules for free from Canon.  DPP does a good job and has the same colour characteristics and the camera.  Edit them to your taste, use the distortion correction, digital lens optimizer etc if it is a supported lens.  Then export a 16bit tiff for futher editing in Photolab if more is needed.  Then remember to use full RAW files in the future.

One more comment to the sRAW file editing.

If someone was careful enough and made in camera a full resolution JPG file beside the sRAW, its resolution is still the full of pixel numbers - regardless to the sRAW file resolution is reduced.
