Straightening different aspects in an image

Hi all, 

Thanks a lot for all of your feedback, it was immensely helpful 🙂 

What is the problem?

To determine whether any of the frames are out of square choose View > Rulers and drag the reference lines from the rulers at the top and left of the image.

You already have some good suggestions posted. However, another idea is to make a rough selection using the Rectangle Marque Tool that includes part of the wall, click Command + J, which will make a copy of the selection on a new layer. You can then rotate/straighten the layer and retouch using the Clone or Healing Brush on the wall. You'd need to do this for each poster that needs adjusting.

Did you mean that the famed posters on the wall are not 100% straight? Looking at the image attached to your post, they looked quite good to me.

If this is a problem, here is another option beyond what Jane has sad.

• Select the area of the posters and copy and paste into new layers
• Fill the wall behind the posters (on the original layer) by selecting an area slighly bigger than each picture framed and choose Edit > Fill > Content-aware. This will guess the missing background. It may not be perfect. You could also use the Clone stamp.
• On each picture frame later, rotate to the right angle through - Edit > Transform > Rotate. 

As Jane mentioned, if you need more detail to the explanation, let us know.

Hi

One way is this:

• Select each frame with its artwork and jump it to its own layer, then straighten it
• Use the Clone stamp tool to paint the missing parts of the wall back in
• Save the layered file in case you need to make further adjustments, and save a flattened file if you need to have that in addition

You didn't say how well you know PS, so ask again if this isn't clear.
