Create Custom Textures in Photoshop (Seamless Patterns + Vector Export)
Custom textures add realism and character to your designs. This tutorial shows how to photograph and process textures in Photoshop, including equalizing uneven lighting, isolating grain on transparency, and defining seamless patterns. You’ll also learn how to vectorize textures in Illustrator for infinitely scalable assets you can use or share.
Step-by-step instructions
Capture strong source textures
Photograph interesting surfaces (grime, rust, paper, windows) in soft/overcast light to avoid harsh shadows.
Shoot straight-on and fill the frame; a phone camera works, but higher resolution helps for print.
Equalize uneven lighting in Photoshop
Duplicate the texture layer twice (Ctrl/Cmd+J twice).
Select the first duplicate → Filter → Blur → Average.
Select the top duplicate → Filter → Other → High Pass → 200 px, then set its blending mode to Linear Light and lower Opacity if too sharp.
Shift-click both duplicates and merge (Ctrl/Cmd+E) to create a flattened, even base.
Boost contrast and create B/W variants
Go to Image → Adjustments → Levels; deepen Shadows and Midtones and push Highlights to remove background.
Desaturate via Image → Adjustments → Desaturate.
Create an inverse version via Image → Adjustments → Invert for white-on-black or black-on-white use.
Export a transparent PNG of the texture
Open the Channels panel and Ctrl/Cmd+click the RGB channel thumbnail to load the texture as a selection.
Return to Layers, add a new layer, and fill the selection with black (Alt/Option+Backspace).
Hide other layers; if you see halos, go to Layer → Matting → Defringe → 1 px.
File → Save As → PNG to preserve transparency and 300 ppi.
Build a seamless repeating pattern
Crop to a square with the Crop Tool (hold Shift); trim soft edges from the photo borders if needed.
Note the exact size via Image → Image Size (round to a clean value).
Go to Filter → Other → Offset and enter half the image size for both axes to push seams to the center.
Use the Patch Tool to remove the seam lines, then go to Edit → Define Pattern; test with the Paint Bucket set to Pattern.
Optional: Vectorize the texture in Illustrator
Copy the processed texture (Ctrl/Cmd+A → Ctrl/Cmd+C) and paste into Illustrator (Ctrl/Cmd+V).
Open Window → Image Trace; enable Preview, check Ignore White, uncheck Snap Curves to Lines, set Corners to 0, adjust Paths/Noise/Threshold.
Go to Object → Expand to convert to vector paths; recolor using the Fill swatch.
Use Pathfinder → Minus Front to punch the texture through shapes; Arrange → Bring to Front if needed.
