how to generate this photoshop pattern?

hi

i discovered a very nice pattern in the original photoshop texture library
(no, it could be, that i installed it also, when i installed the extra plug ins:
http://www.adobe.com/support/downloa...jsp?ftpID=4047
"Adobe Photoshop CS4 Optional plug-ins"
"• Bigger Tiles
• Picture Package (ContactSheetII)
• ExtractPlus
• PatternMaker
• PhotomergeUI
• TWAIN
• Web Photo Gallery (WebContactSheetII) plus presets
• Textures for Texturizer
• script for Layer Comps to Web Photo Gallery"

its named "strands 1.psd"

do you know if i can build exactly this pattern on my own with photoshop cs5 or is it a cgi based pattern?

my goal: i would like to build this pattern again, but in much higher resolution and zoomed in 2 or 3 times. (bigger pattern)

thanks!

Re: how to generate this photoshop pattern?

I didn't dig up the original texture, but you should be able to make something similar just with the built-in tools.

Here I made three layers on a black background. Then i painted using the brush tool with a custom brush.

For this quick test I just took the default grass straw brush that comes with Photoshop, and turned up size/angle jitter and scatter. Painted with white on the three layers, added a drop shadow to each layer (perhaps darken the lower layers).

Making it tile well could be a bit annoying, but have a look at the other>offset filter for help. Perhaps offsetting the layers differently will help hide the seams.

Re: how to generate this photoshop pattern?

oh, could it be possible, that cs5 cant do hires brushes?
i tried your suggested brush, but i need very high resolution and image size,
so i set up an image before at 1270dpi and 20x20cm. then i painted.
(10.000px) and the lines of the brushes are shattered, broken and unsharp, looks like very high jpg compressed. maybe i did a wrong setting in the defined brush?
or maybe because i set the brushsize to its highest possible size (2500 px)?
is it too high?

look please:

Re: how to generate this photoshop pattern?

The Strands texture was included in the Extra Content folders supplied by Adobe with CS3 & CS4. They were in the Goodies folder: CS3>Goodies>Textures For Lighting Effects and CS4>Goodies>Presets>Textures.
If you run the Filter>Other>Offset using 256 px on that image, you can create a Seamless tile of any size and resolution you like.

Re: how to generate this photoshop pattern?

The grass brush I used was just an example. You should create your own brush at whatever size you require. The brush is sharp at the default ("original") brush size, but if you scale it up it won't be sharp (just like any image - a brush is usually just like a grayscale image).

Re: how to generate this photoshop pattern?

i see. whats the original size of a brush?
i would need that strands image zoomed into, like double or 4th times or much bigger at 1270dpi. but i cant interpolate, as i gets blurry and bad quality. hm...

Re: how to generate this photoshop pattern?

Just create your own brush at whatever size you need. Don't use the one that comes with Photoshop.

To make a brush, paint/create one large strand in black on a white background (like my attached sample, but longer and thinner). Select it, and hit Edit > Define Brush Preset... Then go to the Brush panel to edit the size/rotation/scattering/etc.

Ps: "DPI" (ppi) doesn't tell us anything about the actual size of your image. You should give it as pixels (or ppi+in(or cm)).
PPI = Pixels/Inches
Pixels = PPI * Inches

Re: how to generate this photoshop pattern?

yes right, i got it now! thanks

i created a huge document, 20.000 pixels square, 500px/cm and painted with the original brush size.
its very sharp and nice now and double as big as before! i wonder how you made it as big as your sample image? as i cannot increase the size of the brush (112) in order to avoid unsharpness and pixelated views.
although my cs5 is nearly stuck with this image, as it needs 20GB in RAM, and my disc is close to full

actually, your brush and latest image enclosed is beautiful, how did you do this exactly please? (doc. size, pixel, shadow?)

finished the job, thanks!

Re: how to generate this photoshop pattern?

i have explained all the steps, but i can try again. i do not know the specific sizes i used.

i used a hard black brush (with reduced spacing) to draw the black line in a blank document. i guess it was like 1000px big - look at the image. i then made a brush from it (explained above). you might want to make it thinner than mine to make it more like your example. maxed out scattering, size jitter and angle jitter. increase the minimum size to avoid super-tiny ones. perhaps a little bit of roundness jitter.

in the main document (your 20.000x20.000 px monstrosity) i made the background black. then on a new layer i brushed across the entire image with a dark gray.
then another layer, and repeat with a brighter grey.
then another layer, and repeat with a brighter grey.
then another (top) layer, and repeat with white.
(Here i used four layers - you can try even more layers, with less strands on each)

then layer styles on the top layer to add a weak and soft black inner glow. i believe i used 15 % opacity and 20 px radius. then a drop shadow. size, distance and opacity to taste. you probably want a low distance and opacity. tweak until happy. then i copied the style to the other layers. due to the shadows you might want to adjust the brightness of the lower layers until it looks good.

that's it. sorry about capitalization, but i am on a phone :p
