In Photoshop, there’s usually more than one way to skin a cat. Here’s another:
1.Choose the rectangular marquee tool (top left)
or any other selection tool.
2. Use it to select a suitable area of the brick wall (we say ‘select’, not ‘crop’
). I chose the top right area of the wall.
3. Ctrl-C for Copy (or go to Edit – Copy), then Ctrl-V for Paste (or Edit > Paste)
This has created a copy of the selected brick wall area, in a new layer atop the rest of the picture (like a transparency sitting atop the main pic). You can see these layers if you open the Layers window via Windows > Layers (F7).
Next you want to drag this pasted overlayer to the window area. Hold down ctrl and drag the mouse from the selected brick wall area. You’ll see the pasted image slid over the top of the pic. Move it into place over the window. Line it up so the bricks are suitably placed.
Now to get rid of the sharp edges of the overlayer, select the Eraser tool (left column, 6th tool). Go up to the tool presets bar, which is the bar just below the File/Edit/Image words. Where it says Brush and then it has a round dot and a number, click the down arrow. Select a fuzzy-edged brush (2nd group), of about 21 diameter. Go further right to opacity, and select about a 50 or 60, which means it will make the erased area transparent with fuzzy, soft edges, ideal for blending layers.
Go to the pasted overlay, and gently erase some of the edges to try to get it to blend into the pic better. If you erase too far into the window area, the dark window will show. Use UNDO or step backward to undo the erasing if you go too far. (Edit menu) Experiment with brush sizes and opacities until you get the effect you want. Don’t be afraid to play around and screw up – that’s how you learn.
Finally, if you really want to get it perfect, since the bricks you copied might be lighter or darker than those surrounding the window area, you might not get a perfect match. Just use ctrl-L or Image > Adjustments > Levels to open the Levels window, and pull the center arrow right or left to adjust the brightness of the pasted area until it matches perfectly.
If the alignment is still a little off (since the brick wall is a bit wavy), you might want to rotate the pasted area slightly (Ctrl T or Edit > Free Transform, then move the cursor outside the box which appears, and drag clockwise or counterclockwise for a slight adjustment; hit Enter when you’ve got it right.
Layer > Flatten Image will then collapse your two layers into one pic, and you can save it. Here’s my result:
Just a quickie of course, so it’s not perfect, but you get the idea.
