Photoshop: Image with pixels of multiple sizes

I'm a painter and was wondering about Pointillism with multiple brushes with different diameters. Using large diameter for background and small for figures, or large diameter for shades and small for light. If that idea is applied to the pixel screen, could it create a 3D effect? It would be an image with pixels of multiple sizes.

Hi Ana, by the absence of replies here I'm guessing I'm not the only one having trouble understanding your question.

I do know that the resolution of an image, the DPI or PPI, dictates the physical "size" of a pixel, and that it's a fixed value for any given document.

Hi. I guess it is impossible unless you have a screen with multiple layers that become active in certain areas and inactive in other areas. For example, the layer with an active background will have the areas of the figures inactive, and the layer of the active figures will have the area of the background inactive.

I think you're thinking of different masked layers with a live pixelate filter set at different strengths, but I wouldn't know how to make that. That's also a guess, as I'm having trouble understanding your terminology.

• What's a screen with multiple layers?
• How can a layer have an "active" background? - AFAIK a layer either is, or isn't, the backmost (background) layer.
• What's a "figure area"?

The screen would be physical, like in a tablet, phone, monitor, laptop, etc. Now it only exists in my imagination and I don't know if it is possible.
By active I mean with light and inactive without light or turned off.
Each layer would be of a different pixel resolution, from a greater size to smaller.
The layer of the background could be of a low resolution, the layer of the figures with a high resolution.

#1 Make your document the highest resolution you need.
#2 Make documents of lower resolutions, as needed.
#3 Import them as smart objects into your high res document. Take care to use a scaling method (I'm guessing nearest neighbor) when upscaling the smart objects.
#4 Sort them to your heart's desire.
#5 Maybe use an extension panel like "Canlinkit" (http://www.canlinkit.com/ ) to stay on top of changes in your smart objects.

*edit* make sure you make the low-res files with the same aspect ratio, and then scale them to the full "size" in the high res document.

Fun fact: illustrator has a sweet live pixelate filter, too.

Thanks for your replies. ^_^ I'll check the pixelated filter on illustrator.

I guess my question has more to do with screen manufacturers and less with an image created with a program like Photoshop.
