I have a 10" android tablet and 15" laptop. Darktable and GIMP is installed on my linux laptop.

Controlling sliders/curves etc of darktable /GIMP from mouse is not efficient, for me at least.

I see the following possibilities

  1. Either I need to make shortcut for all the different sliders and somehow remember them all
  2. Or I need to use tablet as control device
  3. If you have something else , please share.

I would like to go with solution 2.

For image processing a touch device mainly tablet can be a killer device , if an app can do everything from gestures,double tap,single tap, multi touch, drawing and tap-hold.

I know that tablet can be used as extended display but that's not the only thing I want even though it helps to certain extent.

So basically I want to increase my image processing efficiency using tablet beyond extending the display , is it possible ?

    You might get better results with this on the Android Stack Exchange, or the Unix/Linux one. Is there something specific to Darktable or Gimp (or really, image editing in general) here? – mattdm Dec 8 '14 at 20:23
  • Photo editing is the main purpose. Basicaly I want to control darktable and GIMP. On stack exchange answer is there for how to extend display using tablet. I posted here in a hope that I would get solutions optimised for image processing only. – Alex Dec 9 '14 at 3:57

    Can you help me understand why or how image processing applications would be special in this regard? – mattdm Dec 9 '14 at 3:59
  • @mattdm, I understand your concern. My idea was to eliminate general solution and stick to some specific "Photo editing" related solution like GIMP script/plugin/tool etc.In this forum I could find people who might be using some kind of tweaks in open source GIMP/Darktable similar to my needs because users of photo editors must be here if not in stackexchange. If it still doesn't make sense then I am happy to move this question from here :) – Alex Dec 9 '14 at 13:31

A combination of 1 and 3 is what I do. AFAIK, there's no tablet options for darktable

Setting keyboard shortcuts for the most frequently used options, once you've pushed the keyboard shortcut for the option you can do a couple of things.

  1. Pushing the mouse left/right will then adjust the curve up/down. (assuming your mouse is over the tools panel, not the image - you have to flick the mouse both ways before it starts working)
  2. Typing in a number directly allows you to jump to a particular number - it takes very little time to get an intuitive feel for the numbers involved.

I find option 2 to be the most productive way of editing. I normally get the exposure adjustment correct on the first go now, and a second adjustment is very quick.
