Photoshop has one hidden gem ‘Pattern Maker’ that can be very useful for beginners and intermediate users. You can generate cool looking patterns from any selected part from any image. Final result can be very different and creative (sometimes gory!) from ordinary looking images.
Steps to Generate Pattern
1. Open Photoshop, then goto File > Open
2. Then browse to any image stored on computer and open it.
3. Then goto Filter > Pattern Maker, settings pop-up box will open. Using marquee (dashed) rectangle select any part of image and then click on generate button to see cool looking pattern image.
There are number of other options which can be used to refine final pattern. You can add boundary, select level of smoothness and sample detail for selected part of image. Get creative and generate some cool looking pattern images.
