Pixelated

I saw a post on usenet that reminded me of this old puzzle I keep trying (unsuccessfully) to solve.

Take a photo, any photo, and make it look like it's getting progressively more and more pixelated until they actually start to fly apart.

I guess the hard part is the pixelation. Once a way to attractively pixelate an image is found, we can work on making a progressive version.

By the way, "pixelation" is when pixels get so big you can see them. I'm looking for a way to make an image look perfectly normal on one side, and the pixels get smoothly larger towards the other side. The 'fly apart' part is a frill, and easy enough to do.

Not even close, but I had FUN trying!

I fiddled and struggled (mostly the latter) with this on and off today. Came nowhere close to where I think Doug is trying to go and after a couple hours of frustration found myself strolling aimlessly down Experimental Filterland Blvd. - AGAIN!

Of the many images I just trashed (I think I had a day like Fugitive has once in awhile), here's one that was (to me) at least interesting, so I titled it appropriately (see attachment filename).

Thanks for the inspiration, Doug. I'll try again another day. If possible would you post a link to the image that caught your attention?

If nothing else I got a couple ideas for future projects. That made the journey fruitful.

That's getting there, but more tile-like than pixel-like. And it wasn't a specific image that caught my eye (although I do remember seeing a logo that used a variation on this somewhere).

Try II...

Closer?

Forgive the not stellar layer blending. I'm about to head off to the county fair and wanted to get this posted predeparture.

Danny: Looks pretty cool, and is very similar to what I had in mind, but it still looks like the print is falling apart, and not the pixels.

I wonder how the news pixelates people's faces when they want to hide their identity?

pixelated

If you are talking about the same thing I am thinking of, the pixels separated and some turned different directions and they were different sizes. It is a program, or plug in, and right now I can't think of the name but I saw it in a magazine, later I will try and find it for you.

Doug, when I first read your post, this is what I thought you meant and it's been really bugging me how to do it so I can't sleep and here I am at 2:30 in the a.m. trying to figure it out.

What I finally settled on is this:

1. zoom out so your picture appears very small on the screen
2. take a screen shot of the little bitty picture
3. paste the screen shot into a new document with resolution set to half that of the original
4. zoom out on this second picture until you see the amount of pixels you want (or you run out of screen room whichever comes first LOL)
5. take a screen shot of this pixelly zoom
6. go back to the original picture and paste the pixelly screen shot into a new layer - you will need to adjust the size of the image you just pasted so it matches the original - I selected the content of the layer and used free transform to make it fit
7. take another screen shot of the original layer and paste it into a new document with resolution half what you set in step 3
8. zoom out again until you get the effect you want and do the screen shot and paste again
9. repeat as many time as you want "steps" in the pixalation - when pasting each new layer, make sure the one you just pasted is at the top of the pile.

Now you should have a document with 5 or 6 layers probably called "Background", "layer 1", "layer 2" etc.

Close the eyes of all but "Background" and "layer 1". Make sure "layer 1" is active and add a layer mask to it. Make a rectangle marque at the left side of layer 1 and fill the rectangle with black - this will allow some of the background to show through. Now add a layer mask to layer 2 and make and fill a bigger rectangle. Repeat with the remaining layers one at a time.

Each of the layers you pasted will have a different amount of pixalization so when you're done with the layer masks, you should be able to see the different amounts. I went with a big soft brush and painted black along the edge of each "step" to soften them up a little.

Of course, you will have to adjust each layer for tone and color so they match up and probably have to move the layers a bit so the features line up.

Anyway, with some tweaking, this might do what you want - please excuse any fractured English in the above explanation - I'll try to correct it once I've had some sleep.

Here's the result of my efforts - I didn't worry about making it perfect, I just wanted to show the pixels.

Please excuse the long winded explanation above - it was late (or early depending on how you look at it LOL)

I think I simplified it a bit.

Zoom your original layer until it's around 3 inches on the longest side. Do a screen print of the image at that zoom. Paste the screen print into a new document that has a resolution at something less than the resolution of the original. What resolution you chose depends on how many "steps" you want in the gradual pixalization.

Now zoom the new document until some pleasing degree of pixalization occurs. Take a screen shot of the pixalated image, paste it back onto a new layer in the original document.

Zoom the original again to make it smaller, take a screen shot and repeat the above instructions setting the resolution of the new document lower each time and also zooming the original so it keeps getting smaller.

Make sure you always paste each new layer at the top of the stack or move it there.

When you think you have enough layers, start at the top of the stack and using layer masks, clear away the top layer to reveal the layer beneath and continue doing this until some of all the layer is revealed in a stepwise fashion.

Adjust colors, move layers to line them up etc. and voila, you have a gradually pixalated image. Takes some trial and error until you get the right amount of pixalization etc, but it makes an interesting effect.

Hope this makes sense.

Margaret
