Unwanted feather?

[fruffe]

Hey, I'm kind of new to Fotoshop (CS3), and have run into a small problem..

I have made a small 10x10 px. pic (lets say it's a diamond shape), and want to enlarge this to, say, 500x500 px. to get a sort of "digital" effect, where you can see the pixels clearly.
I use free transform to do this, and it looks fine until I press "enter" to confirm transformation.
Then the pic suddenly gets very blurry, like the "feather" effect.
So does anyone know if it's possible to enlarge pictures of this size, and keep the edges "un-feathered"? I've looked around, and can't seem to find a solution ("feather" and "anti-aliasing" is set to "0").
Alternative is if you know a way to make the same effect without having to enlarge the pic.

Any help is appreciated!

Thanks in advance

yeah theres filters in the pixellate you can play with. also just play around with the filters in general.

Well, as stupid as it may sound, but as it's a small picture (like 10 by 10 px, as you said), you can try to recreate it using the pencil tool.

You'll resize the pic to the size you want, and just fill every pixel with the desired pencil-color. Increase your pencil size (and make it square of course).

Another laid-back quickfix: when you resize it, as you say, the preview looks good. Resize it, take a screenshot and paste it into a new pic.

I know, not really solutions, but it may just work if it's all about this one pic..

Use a custom shape instead (they are basically vectors and are infitintely resizable) or convert your current raster into a vector (by way of custom shape).

If you resize, photoshop will do the math algorithms to make sure that the original and resized images look similar and belive me, they do a wonderfull job.
The effect you want is pixelate.
Draw your design (final size) and play with pixelate->mosaic.
PS will give you some "blur", easily removed by Ctrl+Click layer thumb, followed by Ctrl+Shift+i and del
