I’m currently working on a project where I want to use a grayscale photo of a keyboard as a screened background image. This background will be used on various large scale banners and poster at an upcoming trade show.
The image I’m starting out with only really shows one key and I want to “zoom out” a bit more to expose more of the keyboard.
I’m going to start by opening my stock photo (right) in Photoshop. Since my photo is defaulted to a “Background” in my layers palette, I need to first make it a normal layer by right clicking the background layer and selecting “Layer From Background” from the menu.
Now my stock photo is on it’s own layer, but I still want to have a background to use for editing purposes (more on that later) so I’m going to add a layer and name it “BG”.
I want my finished image to be roughly 2 1/2 times lager on each dimension so my next step is to increase the size of my canvas. By clicking on Image –> Canvas Size (alt+ctrl+C) and I’ll bump the dimensions up as I see fit, in this case I’m checking the bottom right corner as my anchor so that when the canvas grows, my image stays in the bottom right.
Whenever I can, I always like to have my original photo to easily go back to should I make a mistake so I’m going to copy the background layer by right clicking and selecting “Duplicate Layer” or you can drag the layer to the page icon at the bottom of the layers palette.
As you can see I now have one full key with the shopping cart image and 3 parts of other keys. I’m going to start by filling in the key to the left. I begin by making another copy of my original layer. To make all the edges blend easier I’m going to use my eraser with a really fuzzy edge and erase the hard edges of this layer. I usually like to have the center of the brush on the edge, put the opacity at 100% and by using the shift key to constrain my movements to 90 degrees and go over each side.
Next I’m going to set the layers opacity to something like 75% and try to position it so that the key lines up over the next key. The reason I drop the opacity is just so I can see where I’m going. Once it’s lined up I’ll turn it back up to 100%. Now, I don’t really want 2 shopping cart keys so I need to get rid of the one on the new key. There are several ways to do this, but I’m going to use the clone stamp tool. Begin by finding a good area on the key that’s just white and while pressing ALT click the area to sample it. Now use the stamp tool to paint over the shopping cart. I’m doing this on the same layer but you can use a different one if you want. I ended up sampling various places on the key to get my results, your mileage may vary.
Okay now it’s time to fill in the space on that key. I did this by using the lasso and grabbing a similar area on the key to the right of it, pasting it in and then using the eraser to feather out the edges. Different photos will need different techniques.
From there it’s just a matter of using the key you just made to make more keys. I’m going to now make a row of keys in front of the row I just worked on. I’ll make a copy of the layer we were just working on. For this row I’m going to make the keys about 50% larger than the row we just did. Press CTRL+T to transform and hold the shift button as you resize it by dragging out one of the corners. Next I’ll move it down and line it up with the sliver of the key you can see on that row.
Now to do a row above the original row. Same story as above, I’ll make a copy but this time I’m going to transform it and make it smaller and line it up the best I can with the row above. This row required a lot more finesse with the eraser, a brush and the clone stamp. I can’t really tell you how to get things to look realistic, you’ll just have to work on your technique.
From this point it’s just a matter of filling in the blanks. If I have a transparent chunk between parts of the images, I like to use the BG layer discussed above to sample the color next to it and fill it in.
Now that my background image is complete. I plan to use Illustrator to put my banners and posters together.
