I just yesterday upgraded from darktable 1.1 to 1.2, and the first thing I noticed was the new keystone correction feature. I saw in the release notes that it is supposed to be "more intuitive" - but for me it destroys one of the things I liked best about darktable. Or perhaps it is just me who is too stupid to use it.
I have by now, in principle, figured out how to use it (clicking "ok" in the middle etc). That is not the problem. In 1.1 I used to set both the vertical and horizontal slider gradually down (most of the time they ended up having the same negative values) until the results were good. This was a quick and easy procedure. Now in 1.2, if I select "vertical" and drag the points so that the lines run parallel to vertical lines in my image, I get a distorted image. If I correct horizontally as well and align the horizontal lines parallel to each other, then I get _approximately_ what I want. But all in all it still sometimes seems to produce results that I didn't expect. All of this already takes considerably more time than just setting two sliders to the right value. Once I have gone through this procedure, I have to rotate the image again since it is now tilted. And I have to crop it to remove black borders - losing some pixels in the process. That way, keystone correction now takes more than 3x the time it took in 1.1. Or perhaps I am doing something completely wrong, in which case I would welcome instructions how to do it right. Keystone correction used to be hard to do when I used GIMP for all my photo editing tasks, and with darktable 1.1 I finally had a tool that made it easy. Now with 1.2 it is just as hard as it was in GIMP. :( Dear darktable developers, if you are reading this - could you bring back the possibility to use sliders, or at least otherwise make this less painful? After all you can also rotate with a slider. ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
