Convert Image into Dots

[defaultovwfkbch51xl]

Hi Adobe Folks,

I am very interested in turning an image into a series of dots. I want to have the same size dots but just clustered differently if possible. Does anyone have any suggestions on how to do this with Adobe software? Any suggestions would be appreciated!

There is some free software, Stipplegen,  which will do this. It processes the image repeatedly, each iteration providing finer results. It ouputs .SVG files, so Illustrator would be best for editing the results.

Image->Mode->Bitmap and play around with dithering methods.

I am more curious how you generated this image on the right with matlab. How did you do this?

I don't know much about Matlab, but I think this involves Voronoi diagrams.

That does seem interesting but the identically sized »dots« at varying distances and angles (depending on the original image’s luminance) (edit: but without overlapping »dots«) seem so far removed from a classic halftone screen that I suspect they are way beyond Photoshop’s default functionality; a Filter or Script might be able to achieve such results, though, I guess. 

But the software @Semaphoric linked to seems like an excellent match already.

I wonder if ImageJ has this capability as well?

Hi, @defaultovwfkbch51xl the closest you could get in Photoshop, create a white layer below, then use the Dissolve blend mode, strongly reduce the opacity of the image, then flatten and use Filters>Other>Minimum, with preserve roundness, but it is far from a perfec circle...
