Photo-Based Art - - Creative challenge 006: Halftones

DannyRaphael · #1 05-21-2005, 08:48 AM

There's a process referred to as "halftones" which involves dots (or other small shapes) to create an image. (For more in-depth information on the origin and application of the process, do a Google search.) There's a pretty good explanation/illustration here as part of the marketing info for a commercial plugin:

http://www.vanderlee.com/index.php?section=7&page=18)

Photoshop has a couple half-tone effects:
* Filter > Sketch > Half-tone pattern
* Filter > Pixelate > Color half-tone
* Image > Mode > Grayscale followed by Image > Mode > Bitmap (and select from among the options)

Elements probably has the filter effects, but may not have the Bitmap command.

Other programs probably have similar functionalty.

Anyway, if you've not experimented with this effect, here's your chance.

Use your own photo and apply halftone effects to it!

Let's see what you can do!

Here's an application of Sketch > Halftone pattern...

Note: Foreground colors count!
* Click D on your keyboard for (what you would consider) a normal grayscale effect
* Click D followed by X to get an inverse effect
* Set foreground / background colors to anything you like for something exotic!

Here's one via
* Image > Mode > Grayscale followed by
* Image > Mode > Bitmap > Halftone screen

I combined all 3 methods on different layers, experimented with blends, added a blue sepia. Masks

Good to see my "War Eagle" buddy online here. Good job Kiska.

Here is my first try. I didn't do anything that Danny said above

, and created my own abstract of an old grapevine. I liked it better black and white than colored. I've included the original just for grins.

Neat Janet. WHAT is Toadies RU???? Any relation to Toad Suck??

Janet Petty · #7 05-21-2005, 02:32 PM

Toadies are free plugins. The site has some interesting ones. I just wish I could remember how I got to it.

Tis the old age thing ya know.

I love the Toadies filters. Picasso's Last Word is my favorite.

Hope this is what you meant, Danny. I just saved this leaf pic as a WBMP, first as noise, and then as a pattern. I also included the original.

kiska · #10 05-24-2005, 04:55 AM

Oh, Mz Day. Could you elaborate on the above procedure????

WBMP = wireless bitmap????

Save as noise, pattern???

Enlighten me por favor.

raniday · #11 05-24-2005, 03:16 PM

Kiska, when you go to Save for Web, one of your options after JPEG is WBMP, and then you've got a couple of options within that one. Not something you'd want to use often, but it's good to know it's there.

kiska · #12 05-24-2005, 04:02 PM

OH! I was 'saving as', not for the web. Thanks

This is an example of what I LOVE about the Internet... I had NO IDEA this function existed. How very cool.

Inspired, I created an action to simplify duplicating the effect.

The only problem...
The action must be modified before it will work on any computer (except mine). That's because Photoshop "hard codes" the file path specified when the Save for Web (Export) and Open commands are recorded. There's no way to make the path "generic."

Need a favor:
* Try the action
* Give me some feedback on the Readme instructions that explain how to customize it for your computer.

How would you change them?

Thanks, raniday... You just made my day!

Danny, I'm not very literate in this kind of stuff, but I'm glad I made your day

kiska · #15 05-25-2005, 11:24 AM

Hello Danny. Just tried your action and am already stumped. Mac, pscs.

Bear in mind I am not the brightest candle on the cake.

1. Had to make screen shots of stops 3,4,5. Couldn't remember instructions.
2. Can I now, after completing all stop steps, trash the unchecked Export & Open commands??

The action seems fine.

Thanks

Just ran it on a 2nd image, got the attached. Clicked 'cancel', and FIRST image I ran action with popped up. But the end result was on the 'active', 2nd image.
