You're welcome! These are the steps I took, which are suggested as one way to accomplish what you want to do. Please note there are many ways to do the same thing and someone else may have a better/faster way to do the same.
- Open both images. On the B&W image, I made a slight crop to remove the black edge on the right.
- Make a selection of the tractor and people to remove the sky above and between the spokes. Output to a new layer with a layer mask (more on this step below).

Open the picture and add a blank layer. Use filter-Vanishing Point to make a grid of the wall. Click the bar symbol (upper left corner) and from the dropdown choose Export Grids to Photohop. Paste your mural on a layer above the grid and use distort to match the grid lines.
You’re getting some good options because there’s more than one way to do this, you just have to pick one.
Here is a quick demo of another way to get a first draft done in about a minute. You just need three layers and a mask, and it’s adjustable.
Notes:
- Dragging the Quick Selection tool over the wall rapidly isolates a selection of it.
- Adding a Solid Color Fill layer automatically creates a mask of that selection, so that your “wall paint” color affects only the wall, not the entire sce

@harleypublisher So this is a one minute example I made just to find out if this is what you are after or do you want something else altogether?
You're welcome! These are the steps I took, which are suggested as one way to accomplish what you want to do. Please note there are many ways to do the same thing and someone else may have a better/faster way to do the same.
- Open both images. On the B&W image, I made a slight crop to remove the black edge on the right.
- Make a selection of the tractor and people to remove the sky above and between the spokes. Output to a new layer with a layer mask (more on this step below).
- Drag in (or copy/paste) the layer to the Wall photo.
- Resize the image to match the area of the wall (however large you want the image to appear there; I went full size with the woman's hat reaching near the top of the building).
- Select Edit > Transform > Skew. Work on each of the four corners to bring them up or down to match the lines of the building.
That's it! Now, to get into finessing things. In preparing the B&W image (or others in your collection), you may not need to do any background removal. Here, I did this to show more of the wall behind the image. You could also try some stylization of the B&W image by applying a filter to mimic brush strokes. Those don't always go well but worth a test to see if you can get a slight look of paint instead of pixels.
Working with the artist, you could colorize the image based on their vision for the murals. You might want to keep the sky but change it to blue as I've done here, by making selections of different areas and using a Color Balance adjustment layer to add some hues. Again, I've done all this quickly as a concept but I think you'll get the idea.
Finally, when placing the image on the wall, you'll want to pay attention to placement. For this image, the tractor is cropped at the right edge, so I brought the layer all the way to the front corner of the building, otherwise you will see a "frame" (i.e, the right edge of the photo) on the wall. Which might be what you are after? If you didn't want straight edges all around, there are several techniques to try to blend the image into the wall some more. If some walls need a base color, I'd have to see the particular walls to know exactly how best to deal with them but you could try to make a selection of the wall and apply a Color Balance adjustment or another method to neutralize that space.
This sounds like a wonderful project. Are you able to share the name of the town where these will be done?
What projector will you be using? How much 'keystone' correction does it have? My projector does not have any keystone correction because it uses lens off-set like a technical camera, so if I am understanding you correctly, that sort of projector would not work for you.
So it might come down to producing a test image like below and projecting that on the building wall to see how it fits, and if you can correct any keystone error, and then using that as a guide to setting up your images.
A lot depends on the height of the projector of course. If it is located half the height of the wall and perpendicular to the wall's centre point, then it will not need any correction. Without being 100% clear on your objectives, we can only guess at how best to achieve them.
Open the picture and add a blank layer. Use filter-Vanishing Point to make a grid of the wall. Click the bar symbol (upper left corner) and from the dropdown choose Export Grids to Photohop. Paste your mural on a layer above the grid and use distort to match the grid lines.

Notes:
- Dragging the Quick Selection tool over the wall rapidly isolates a selection of it.
- Adding a Solid Color Fill layer automatically creates a mask of that selection, so that your “wall paint” color affects only the wall, not the entire scene.
- Because the wall paint is a Solid Color Fill layer, you can change its color at any time by double-clicking it, as is done frequently during the demo.
- After the farmer photo is added as a layer with drag-and-drop, Edit > Free Transform is used to fit it to the wall. The perspective distortion is done by dragging a Free Transform corner handle while holding down the Command key (Mac) or Ctrl key (Windows). [CORRECTION: You can also do this more simply, without remembering any keyboard shortcuts, by choosing Edit > Transform > Perspective. The way I did it was a more advanced way, using the key press to modify how Free Transform works.]
- The Solid Color Fill layer and farmer photo layer are blended with the wall (letting the wall texture show through) using the blending mode menu and Opacity value in the Layers panel; adjust these until they represent the mural visualization you want.
The animation quality is a little low because I had to compress it a lot to get it under the 10MB limit for an inline graphic in a post.
I am going to throw in another idea, since someone has woken this old thread. An idea I think way more fast and simple than some other ideas in the thread.
We have the tractor cutout and the building.
We make the tractor layer a Smart Object so that a) we keep the handles in their original corner locations, and b) because it is central to making this method work.
Note: I copied the foreground grass to a new layer at the top of the stack, so bottom of the tractor can be placed behind it.
The OP did not say how large the image should appear on the building, so I am going assume about 70% of the height of the building.
Double click the Smart Object to open in a new window so we can edit it, and add Relative 30% to the height of the canvas.
The bounding box will now surround an area relative to the full height of the building, and we can Ctrl/Cmd drag the corner handles into place keeping perspective close to spot on.
We can improve this in a couple of ways. 1) If you have Windows and Lazy Nezumi Pro, you can use its Vanishing lines preset to draw some accurate perspective lines as a guide. Note: I have a Curves layer which I have turned off in this screen shot. This was to temporarily increase contrast between the blocks and concrete pointing so I could more accurately position the lower Vanashing Line.
We can now get the perspective spot on when placing the tractor, and turn off the guide lines.
If you don't have Lazy Nezumi Pro, then a) I am sad for you, and b) use the grid graphic that we should all have in a CC Library. Open the SO to edit, and place your grid layer at the top of the stack. Use that to place the tractor on the wall. Open the SO to edit again, and turn off the grid layer.
