You just need a LP cover / and "blanc damage" images and layer them on top, then blend them over accordingly.
Sounds a bit complicated, but it makes sense if you know what that actually means.
For example:
I use the DeWolfe cover of "Working It Out". I have also selected my "damage" that I want to "inflict" over the clean image.
Normally, a new layer will always obstruct the one below. A layer is, just like in real life, an image or object. If you put your keychain on a letter, the keychain will be on top. (Duh
) But now we want to blend it over. There are many ways for a graphic program such as Photoshop, GIMP or, like I use for 15 years, "PhotoFiltre", they are called almost the same. By doing so, it will not overlay/cover, but merge with the underlying image(s).
Does not look very convincing yet, but now you can play with various parameters, filters, and different layers. For example, setting the "damage" layer only to a 30% opacity makes it more plausible. Maybe adding crispness to both images, simulate older print quality by changing colour values, play with contrast, add "edge filters" to create a bit of a sloppy printing quality/bad printing press et cetera. There are endless possibilities to play with. Also adding real-life logic to things make it also plausible in GFXing: If you have a picture and you drop ink on it, what happens? The ink is ON TOP of the image (the layer above) but mostly dried out (lower opacity, less colour saturation) and the ink will be sucked up by the underlaying cellulose (blending in).
Here I added more contrast to both the damage and the source image, added a lot of yellow colour imbalance to only the source image and added crispness to only the source image again, not the damages. I must admit I just pulled out random stuff, so this is why it looks so cheap and blurry
It's a mere demonstration though. You can find many "damages" on Google. You can use any thing (e.g. "old paper"), but if you happen to have an old, white paper sleeve of your LP, take an upside-down picture of it so you have the outlines of the disk visible. Now "layer" it onto the usually clean and perfect CD inlay, either by using the blend modes or by "Alpha channeling" (read as: Removing) the white sleeve so only the outlines and paper wrinkles stay. It is actually that easy.
In this example I added a layer of "dust" to it, again cheeply within 30 seconds, but it's just a demo again:
I make guides for a video game in the style of "old, gilded paper" but of course, the video game itself is modern and colourful. I use many "old paper", "vintage book", "wrinkled paper" et cetera, often layering 10+ more of them carefully together. After a while, you will get the hang of it and it's actually pretty cool. Since all the programs kinda work the same but use different steps and menus, I can only stay superficial like this.
