Why not leave the current situation as it is, but add a CTRL key modifier to allow the alternate behaviour?

Subject: Re: [darktable-dev] Crop tool is awkward for my use case
To: <darktable-dev@lists.darktable.org>


For some people that might be true, but the current system also has an
advantage: if the shot is already pretty good but just needs a slight
cropping, then only a little dragging in one corner may be required,
without much dragging. Then the click-in-square method for moving the
crop is actually useful. I would not want to have to drag a rectangle
for every little crop adjustment.

How is this a JPEG vs. RAW issue? I have done a great deal of cropping
in Darktable (on both JPEGs and RAWs) and I think that adding the
proposed single-drag interaction would speed up cropping a great deal
over the current process, no matter the format of the image being edited.

Although darktable handles JPG images very well, I think that its
primary market was targeted towards users who shoot RAW with an
expectation of doing more complex processing on individual frames.
Maybe darktable is simply the wrong software for your high production
needs.

I find the crop tool to be unwieldly for my common use case, namely
processing a large number of photographs from shooting sports.

I shoot a lot of basketball and (American) football games for my alma
mater.  My workflow is to import the typically ~2000 photos into
KPhotoAlbum, review them and select the ones I want (typically 300 or
so), and create a directory with symlinks to the selected files.
These are essentially all JPEG; RAW would simply consume too much
space and slow the camera (Canon 7DmkII) too much.

The postprocessing I do is limited to cropping and rotating, if my
camera was not level (typically it isn't perfectly level, as I'm
shooting handheld bursts).  I gave up on noise reduction last year;
the 7DmkII is good enough even at ISO 6400, and additional NR really
slows things down.

The difficulty is that to crop the frame (always freehand) requires
the following motions:

1) Position the mouse near one corner of the image (say, top left),
   which may be nowhere near where I want to crop.

2) Click and move the top and left edges (via the top left corner) to
   the desired spot.

3) Move the mouse to the bottom right of the image, which again might
   not be near where I want to crop.

4) Click and move the bottom and right edges to the desired spot.

With RawTherapee I simply place the mouse at the desired top left
spot, click and drag it to the bottom right, and I'm done.  The extra
motions with Darktable, especially since they have to start far from
what may be my point of interest, are awkward and cost maybe 5 seconds
per image.  With 300 images, that's an extra 25 minutes; this past
Wednesday I shot two games that totaled 700 images, so the extra time
would have been an hour.

I'd prefer to use Darktable for this purpose, since it's otherwise a
lot faster.  RawTherapee takes maybe 3 seconds or so to export an
image; Darktable is more like 1 second, not to mention that the rotate
function is easier in Darktable (right mouse drag).  But the current
behavior of the cropping tool is simply too awkward (I tried it for
one set and it really did take a lot more time).

I tried looking at the code (in src/iop/clipping.c), but it wasn't
obvious to me what would need to change to do this.  I understand that
dragging inside the frame is used to move the crop box, but that's
rarely something I need to do.  I have at least two more games this
season to shoot, and if we make it to the later rounds of the
tournament, I'm going to have a lot more photos (less selective about
what I keep).

Perhaps what I really need is a very minimalist program that lets me
set the crop and rotate and do nothing else, but I haven't found such
(on Linux).

Thoughts, anyone?
