@reyalp,
Can you compile and post one without the shadowed lines so we can compare it to the jpgs that the A590IS produces.
Attached.
I think that most people would crop those shadowed linesif they have a choice. I wonder if the cam crops this too before creating the jpg internally.
Of course it does, camera jpeg is only 3264x2448
My thoughts on this:
- these pixels contain image data, so it is technically "active area". If I understand the DNG spec correctly it should probably be included. See
http://www.barrypearson.co.uk/articles/dng/specification.htm#areas The default crop area is already a separate item, and is set to JPEG size in the CHDK DNG code (although the origin is just set to the middle of the active area, which may not be the same as what cannon uses)
- people who take the time to set up a raw workflow are mostly going to crop their photos anyway. If you want to use snapshots as is, just use jpeg.
- these pixels could cropped (or quite likely, recovered) automatically in the workflow.
- the data is in the DNG regardless, so there is no time or space savings.
I am open to arguments to the contrary, or information on how other cameras do it.
