Thank you for the play.

Thereafter GIMP and G’MIC:
Definitely needed to perspective-correct this one. I tried to bring up the contrast, but couldn’t quite separate the Cafe logo from the reflections well enough.
Is there a perspective correction tool in DT like there is in RT/ART? Perfectly straightening the lines is fully automatic in RT/ART.
There is definitely a perspective module, but IDK whether it meets your needs. The module is named “rotate and perspective”.
Yep. It offers manual adjustments, but also does some edge detection to find horizontal and vertical lines and can attempt automatic correction. That’s what I used here.
Bruce Williams has a nice tutorial on it: https://www.youtube.com/watch?v=HWT_LWP0dkY (The UI has changed a bit since this was made, but the function is still the same)
