I have only had one previous attempt in this thread and I made a ballhooks of that. I’m a bit slow on the uptake, its an age thing, not sure about drop box and such?, but any way I’ll have a go.
OK, here goes. In PS.
Open image, add 25% to canvas, using the crop, if you are using 5 or 6, if not, do it with canvas size. Copy layer.
Pull out seven vertical guides, RH main brickwork, inner RH brickwork, the open door, LH inner brickwork, outer LH main brickwork; LH extended building brickwork, pipe on building.
Then four horizontal guides, along the black bricks, along the windowsills, along the guttering, along the top of the roof.
Using the magic wand select the added canvas (white), inverse the selection.
Go to Edit-transform-skew. Pull out the sides and generally move the image sides until it lines up to the guides. Ignore the shape it will now extend into the added canvas.
SAVE.
At this point, depending on which Photoshop you are using, you can either crop to exclude the stretched parts or as I did, using the polygonal lasso select the white triangle shaped area on the lower left, overlapping slightly into the image.
Now go to edit-fill and with content - aware in the use box, fill the area. I was lucky it made an excellent job; the outcome is different every time. You may have to do a bit of extra work to get the desired result, clone etc.
Repeat this for the RH side, I had a lot of work on this side the content-aware failed, I had to make smaller selections, clone, and make small new layers from the area to move and blend.
SAVE.
The road on the left had lost its white line, to correct this I made a selection across the road including the centre line, copied and pasted it to put the selection into a new layer then moved it across and stretched it with transform until it looked right.
Crop to get rid of any white canvas that’s left over.
SAVE.
Copy and rename the new layer “mono”
Change the layer to mono, use whatever method you prefer.
Create a new layer, on this layer, add a 45% gray grad to the sky, pull it down to the lowest roof level.
Pull another grad up from the bottom up to the top of the railings. Alter the opacity if its too dark or add another grad if its not having enough effect, now on the top image layer dodge and burn the sky, windows, gates and signs, when happy
SAVE.
Switch off the colour layer. Merge the grad and mono layers. Switch the colour layer back on, select the mono layer, add a mask to this layer (the box with a circle in it at the bottom of the layer pallet) click in the mask, it’s the box at the side of the mono in layer in the layers pallet.
Select a soft round brush, make sure the back and foreground colours are set to black and white and then with black as foreground and the brush set to about 25% opacity paint over the main colour elements in the picture the phone box, railings, doors, bin, signs the blue in the sky.
SAVE.
Now reduce the opacity on the mono layer to let the colour from bellow start to show through, when your happy flatten the layers and SAVE.
Done! I think.
