How to create a rectangular picture from a distorted one ?


Recommended Posts

In a museum I took a Photo of a painting from an angle, both horizontally and vertically. The resulting picture is distorted.

Now I would like to correct the perspective to a frontal view.

In AP I have not found a solution for this task (See first screenshot). The transformation studio seems not to be up to this seemingly simple task of a coordinate transformation of the pixel cloud. Even my iPhone-Scanner does it in an instant, on each document.

Then I have tried Snapseed which contains an option to do this modification easily - of course this is not what I want to do (see 2 further screenshots). I did not use the original photo but transformed the screenshot taken from AP before. So the AP-User interface is transformed as well.

Anybody got an idea ?

There’s a Perspective filter in the Filters Studio (accessed via the filter funnel icon on the right-hand side).

If the Source/Destination control is set to ‘Destination’, the image should change as you drag on the corners of the grid (and its final appearance should be fixed when you tap on the check mark).

O.K.

I tried to place the grid on the edges of the picture. This is how the other apps work - they blow this shape then up to the designated rectangular format.

AP works exactly the other way: The edges of the grid have to be moved outside of the picture area until the edges of the object meet the pictures outline. Because each movement affects the other sides of the object as well, this is more complicated. It took me 3 passes until the fit was acceptable to me.

So it is done, but I do not like it. It is practically impossible to make a really good perspective correction „to the pixel“ this way.

Anyhow, thank you for the assistance.

My method on iPad version, steps are the same on desktop:-

  1. Create a rough cutout of picture
  2. Create a dimensionly close new frame
  3. Use perspective filter tool and position into new frame
  4. Remove new frame and use it as a clipping mask to remove uninteresting details
  5. Export
