How I make background textures, by sinecure.How to make a grunge-type background. I picked things up here and there and everywhere, but this is how I've been making mine.1. Open a new image to the size you want to make it. I've been doing mine at 800x600, but 1024x768 works too. It takes up a lot of memory on your computer when you're working on it though, so, be warned that things will run slowly.2. I sort of decide what colors I want to work with and flood fill the layer. It changes with blend mode colors though, so it can end up the complete opposite of what I started out with. PS default brushes are great to work with. I use the round ones, the square ones, splatter and chalk a lot, plus my own, and sometimes other people's. So, open your new image and pick a color, any color. ;) Flood fill your layer. I'm making one along with this tutorial, and the color I chose is #66562A3. New layer. Pretty much each new step is going to be a new layer. Selection tool, set to feather about 10 or so. Draw a shape somewhere, anywhere you want, and flood fill it with a color. I used #754507. I moved it, rotated it, and set the layer to Luminosity.4. New layer. I made another selection across the previous one and chose a lighter color. Luminosity, opacity at 35%.5. New layer. Another selection, this one over both the others. Color is #815A27. Soft Light, opacity 60%.6. New layer. I grabbed PS's default round brush. Size 1, Hardness 100 and just went around the canvas, painting lines here and there. Set to Soft Light and lower the opacity to 15%. Wet Edges is selected.7. New layer. Same thing as above, but with black instead. Soft Light, opacity 10%.8. New layer. I picked up a color from a light area of the BG, which was #79693D, and used the Splatter brush, size 58. I drew around the top right edge a little and then clicked it along the edges of the press, like stippling. Same on the middle left edge. Set the layer to Soft Light.9. New layer. Using the background color that I originally filled my first layer with I stippled over the previous brush strokes. I set it to Luminosity and then Gaussian Blurred it at 8.10. New layer. I unchecked Wet Edges and grabbed the square brush. I grabbed a darker color, #4B3E1A, and drew with the size 9 brush. I traced roughly around the edges of the entire BG, then drew some lines inside, haphazardly, here and there. I set the layer to Hard Light and the Motion Blurred it. Angle 50, Distance 320.11. New layer. I downsized my brush to 1, and my color to white. I drew around the edges, very roughly, like one would sketch. Set the layer to Screen, opacity to 5%.12. New layer. Color#AA8724. I used various blood brushes here and there, pretty sporadically with the larger blood drops. I set the layer to Soft Light. I changed the brushes about six times to vary the size and shape.13. New layer, smaller blood drips, I painted them in more places with a red color, #6D1E1E. Color Burn, 20%.14. New layer. Same color, different blood brush. Small droplets, but it has a square edge on all sides, so I placed it once on the top right corner and then used the Lasso Tool set to Feather at 5, and selected the inside edges, then hit Delete. Set the layer to Multiply at 25%. I liked this a lot, so I duplicated the layer, rotated it 180% and placed it over the previous blood drips and lowered the opacity to 20%. It gives the impression of depth.15. I made a brush of a taped up picture of a butterfly last night and decided to use that. You can get the image from Veronica Mars' caps. It's in her locker. Or, use mine.(Simply open it in PS and choose Edit/Define Brush, or in PSP, open it and open your brush palette and choose New Brush... I think. It's been a while since I used PSP. I know you have to select the image and then do it.) So, I used #DDD969 and clicked it once over one of the shapes I'd made back in the first steps and set the layer to Color Burn.16. There's a text brush that I got way back when. I didn't save who it was by at the time, because I was bad like that. I wanted to use it, but I'm trying to use just my brushes on this one, so I made my own. It's not even close to being as great as the other one, that I love, love, love, but it's decent. I used #508999 and clicked a little in the top left corner, the bottom middle, a little on the top right and once on the bottom right. I added another layer and darkened the color to #364846. I set the lighter layer to Screen 35, and the darker one to Color Dodge at 85. Although, a lot of the blend modes looked cool. I sometimes have trouble deciding which blend mode I like best, but I think that's what I want now... could change later.Yay, misquoted quotes!17. New layer. I picked up a dark color from the middle of the butterfly, #4A3003, and flood filled the layer. I went through all the blend modes, deciding which one I liked best, and again, it's a hard decision to make. I'm torn between Screen and Difference. I think I like Difference more though. So, Difference it is. However, now some of the scratches stand out too much, so I lowered the opacity of the first white scratch layer to 8%.18. New layer. I chose the Paint Bucket and selected Pattern instead of Foreground Color. I made some patterns a while back, one that I called Gingham, and flood filled the layer, set it to Soft Light and then used the Lasso Tool set to Feather at 5 and drew a squiggly frame around the entire thing and then hit Delete. I lowered the opacity to 30%.I'm trying to remember how I made the Gingham pattern. I think I opened a 100x100 transparent image and used the selection tool to draw a line horizontally and flood filled it with gray, then did one vertically and did that for ten rows each, then copy/pasted them until the entire thing was filled and lined up right, then merged and Defined it as a Pattern, just like you do with a brush. I'm sure there's a much easier way to do it, but that's how I just recreated it almost exactly.19. New layer. I used a denim brush that I made ages ago, and clicked four squares two wide, two high in #ACA694 and set it to Soft Light. I added another layer and clicked slightly over to the right, or up, but on top of the previous layer, in #7A7469. I moved the darked layer beneath the lighter one and set it to Multiply. I linked them together and rotated them to the left a ways and moved them to the lower right corner. I selected a jagged circle and inverted it, then hit delete from both layers.20. New layer. I went back to the 1-sized round brush, set the Hardness to 75 and drew lines in #294315, directly across the middle, but not perfectly straight. I added little pieces coming off of the line, and drew others around the edges here and there. I set the layer to Hard Light and duplicated it. Click the mover tool and, using the arrow buttons on your keypad hit left once and up. I set this layer to Screen, opacity 45%, then Motion Blurred it. Angle 4, Distance 15.21. New layer. I used #042758 and the largest chalk brush. I drew over the previous layer's lines and a little extra here and there. I set the layer to Screen and Gaussian Blurred it at 45. It gives us a little bit of light in some areas.22. Same color. I used the preset shapes tool. The one that looks like a donut. I drew a circle on the lower right corner, partially off-screen. I set the layer to Color Dodge and duplicated it twice, setting the middle one to Screen and the top one to Difference. I Gaussian Blurred the lower one at 18, the middle one at 30, and the top one to 10. I lowered the top layer's opacity to 10% and then Motion Blurred it at angle 4, distance 75. I did that twice.23. New layer. I selected an area around the circles and a little beyond and flood filled it with #0D161B. I set the layer to Hue. It's a very subtle difference, but it helps the previous layers to blend in a little.24. New layer. White. I used the size-1 round brush again, set to 100 Hardness and drew a few tiny lines here and there. I placed some dots around the entire image. Set the layer to Screen, 5% opacity.25. New layer. I used a gold gradient, set to Linear I drew from the top left to the middle right. I lowered the opacity to 25% and set it to Overlay.26. I drew a star from the preset shapes and duplicated the layer. I moved one to the middle left so that it was half off-screen. I moved the other to the bottom middle, half off-screen as well. I set them both to Overlay and Gaussian Blurred them at 32. I changed the blend mode of the bottom middle one to Soft Light and lowered the opacity to 60%.27. I didn't like the lines in the middle anymore, the ones from step #20, so I lowered the opacity of the Hard Light one to 30% and the Screen one to 10%.28. New layer. I roughly drew a long rectangle from side to side, not all the way though, and made it crooked. I filled it with the golden gradient and set the blend mode to Multiply. I moved it down to the bottom, where it's brightest and Motion Blurred it at angle 20, distance 200.29. I duplicated the gold gradient from step #25 and set it on top of all the other layers. I changed the blend mode to Color Burn, and the opacity to 15%.30. New layer. Because I can't stop messing with the color, I flood filled this layer with #B7E5B5 and set the blend mode to Overlay, 90%.31. I'm expirementing here, but I drew a rectangle in the middle and flood filled it with #B7E5B5 and set the layer to Difference. I duplicated it and set this one to Multiply. Again, and set it to Overlay. Again, and set it to Color Burn. Again, and set it to Overlay. I moved the Difference layer to the top right, lining it up with the edges. I moved the next layer to the left, overlapping it a bit and down. The next, I moved to the top right, overlapping all three layers. The next, I moved down to the bottom middle. The last one I filled in the last remaining space. Now I clicked the top layer and hit Ctrl. E to Merge Down. I did this for just those layers, which means 4 times. Kind of cool. I motion Blurred it at angle 0, 200 distance. Eh. I changed the blend mode to Multiply. Okay, I kind of like it. But, I'll have to leave it a while and then come back later to know if I really like it.32. Leave for a few hours. Check it, see if you like it. Seriously. A lot of times I work with something for a long time and think I love it like that, but then end up not liking it the next time I see it. So, now I try to walk away for a while, or just do other things for a bit online, and then flip back to it and see if it's still as cool as I thought. A lot of times I end up muttering, 'what was I thinking?' and changing it.33. I'm back. It's a few hours later, and I still like it except for one thing; the Screen and Dodge layers of the text brush in step #16 are too bright. I set the lighter layer to Soft Light, 100%, and the darker one to Color Dodge at 40%. And... I'm done.Clickety-click to see the end results.
