If you’re looking for something weird and fun to do with your photos, I’ve got a cool trick for you.

It’s called rasterizing.  I think.

Here’s what it does.  It cuts your picture into tiny little squares and then rounds those squares into circles. (Not the official definition.)


Maybe I should just show you.

Begin with a photo.

I think it works best with really active shots, but we’ll try this one.

Take a click over to www.homokaasu.org/rasterbator.  Don’t let the name throw you off.  It sounds foul, but it’s just an attention grabber.

Before you can rasterize your image, it needs to be in a file size smaller that 1MB.  If you have Photoshop, click File>Save for Web.  About half-way down the page, you’ll see constrain proportions and a percent box.  Change that percent down and click apply until you get under 1MB.

Then upload your image to the rasterbator.

After the image has uploaded, you’ll have the option of cropping it.  On the right side of the screen, you’ll see two buttons “Crop” and “Size”.  Crop indicates the size/proportions of the image.  Size means the size of what you are about to create.

And what exactly am I creating?  A multi-page image you print on your home printer.  I suppose you could send it to a digital photo lab, but the cool thing about the rasterbator is you can make HUGE images for free.

Well, almost free. You still have to buy computer paper and printer ink.

When you click on size, you can resize your image in the little grid.  Here, my image is four grid spaces high by four grid spaces wide.  That’s four by four print papers–sixteen papers.

At 8 1/2 by 11, that makes this a 34″ by 44″ photo.  Almost three feet by four feet!   That’s big. 

The next screen will ask you to set your preferences for color and dot size.  I chose the color option that uses the median color for each dot.  That makes the least amount of change to the image.  Black and white is cool too, though.

For dot size, I used the smallest, 7mm.  This will give you the least amount of distortion. 

I’d have to print the thing and photograph it to show you the result and this was just for illustrative purposes only. . .so I did it again making it one page this time.

The result is quite distorted.

The larger the output image is, the smaller piece of your picture each dot is, therefore less distortion.  With the image only one page in size, the dots were a fairly big piece of the image so it looks dotty.

But if I had done sixteen pages, you would be able to clearly see the picture. 

If that makes any sense.

Okay, Lady, what do I do with sixteen computer papers?  

Glad you asked.  You can paste them all to a board, foam core, or the wall. Or, you can buy sixteen of those document frames with hardly any frame and hang them super close to make one wall collage image.

My friend did this in her daughter’s room with a super cool cheerleading picture.  This one.


Imagine walking in to the little girls room and seeing a huge wall image of that.  It’s totally rockin’.

Maybe I can talk her in to taking a picture of the wall and sharing it with me through Flickr or Shutterfly.  Then I can add it to this post.



We’d love to see it.

Pretty please. . .

It’s important to note, if you’re going to use the letter sized frames, you should crop the picture to fill only the pages.  Notice in mine it used sixteen pages but it was only on a small strip of the last four pages.  I could have cropped it to be only twelve pages without really changing the size. 

Clear as mud?

Have fun photo-fiddling.


Yay!  Look, I talked her into sharing.  This is what a rasterized, framed image can look like on the wall. 

Totally Cool!

You can see that from a distance it looks like a poster.  But it’s SO much cheaper, and frankly more awesome, than a poster print of that size.

Thanks for sharing, Coco! 🙂
