Hi, what may the reason be, that one pic changed with tool trapez the perspective of a house shooted up, not with shift, is bad unsharp and anotherone is fine? Is there a way to go step by step to the same result? Some trys cut the house, some not.
I move helples the sliders... Thx, lars

Hi Lars
I think that you maybe asking about the "Keystone" tool.

I observe that the Keystone tool has 3 modes, "Vertical", "Horizontal" and "Vertical and Horizontal".

There are three buttons at the bottom right of the "Keystone" tool to select this mode. If you have not selected a mode, the sliders will not work.

If have not understood correctly, perhaps provide the exact spelling of the tool name in your language (German?) and I can try Google translate. (Google translate may give me a better understanding of your question, with my own knowledge and the assistance of Google translate I can usually get very accurate results for Dutch, German and Swedish)

Hi Eric, the sliders work. 1. One can use them first, the pic change then and one can use vertical keystone (in the German menu: Trapezkorrektur, english: trapeze correction) to change the perspective (vertical). But that is only "by the way".

2. But this tool needs one function more, to make a portrait format smaller. I did it in Affinity Photo with Meshes to get correct relationship, in the pic (above right) it is 3.6 high/ wide (as I see it in a photography made with shift; left). Regards, lars

Hi Lars
Perhaps the function you are looking for is the Crop tool, which selects part of the image and also increases the magnification.

Thanks, not the frame has to become smaller, but the object/ house itself. The relationship high/ wide must change, for the image of the house is pressed or the top of the house is cut off. lars

Lars - isn't this the same discussion we have already had in another thread?
