Create a repeating tile saved in PNG format to keep the transparent background and then you can overlay it over any image or make it any colour you need.
I would personally use the pattern generator in illustrator but if you don't have access, you can make repeat tiles in photoshop
I have made a quick video of how you can achieve this kind of effect. (let me know if you miss anything)
You will need to have a play with all the settings and how you do it overall but hopefully this will give you the idea of how to achieve it.
I hope this helps..?
Thanks, this looks promising - I'll make sure to test it at work on monday and see what I can come up with.
Thanks for the info, but I'm inquiring about this specific pattern, the one in the little box in the bottom of the image.
Thanks a whole bunch for the video.
Even though it's not exactly the same as the example I posted, I really like the effect and will use this! This leaves me wondering how you got to the effect you show around 3:35 in your video though.
Hi dennbern, the bit you see on the 3:35 frame is a pattern that I found to use as a reference on how to achieve the kind of effect you were looking for found here: http://upload.wikimedia.org/wikipedia/en/6/67/Homebrew_reaction_diffusion_example_512iter. jpg but like I said if you play around with the setting but use the same process you can achieve something very similar. I have just tweaked the setting I had and achieved this:
(this was created on 1000x1000 art board then I cropped the edges to finish, brush size of 31px, 400 spots on the art board, then recorded action of high pass setting 9.0, threshold setting of 102 and Gaussian blur setting of 4.6 then repeated 23 times then threshold of 190.
So very much like the frame you saw. :-)
The thing with the process is that you can achieve so many different outcomes and you will have to play around with the settings until you get what you want. If you want to add other looks you can throw a few lines into the original pattern like this:
outcome is this:
I hope this all helps you get the look you are after. :-)
Thanks very much, I'll experiment some more with it.
I used a scatter brush for the dots, this was with black dots on a white background.
in this one I also used a scatter brush with lines to get something closer to your example
I'll mess around with the settings, shapes, etc some more to see what else I can come up with.
Want to get them more connected with long lines like the reference you used, guess it's just more manual labour to get them like that.
They kind of look like those microscope images of diseases now, haha.
Great, glad you are starting to get the effect you were after.
