Hi, I am working in archaeology and a problem we face is that we take pictures of archaeological features in the field, but they are almost always taken in an angle. Therefore, these pictures are somewhat different/off in perspective and not correctly scaled from for instance a drawing of the same feature. I wanted to use the transformation tool 'perspective' for this, but I have the idea that the whole picture is distorted.
In the attached images, there is one that is from the field and taken in an angle and one that I tried to change the perspective. In the third picture I have placed arrows at the spots where I put nails in at the same distance of each other, so that I could scale the picture to the correct perspective.
So, did I do the correct transformation/correction to my picture to correctly scale it to a kind of horizontal perspective or should I use another function in Photoshop or any other Adobe program?
If I did it correctly, is it possible to use the four nails as a kind of reference points to fasten the process? Or is it maybe even possible to automate this process?
Anyway, thanks for the help.
