I'm having problems selecting a single pixel in photoshop. Whether it be trying to use the clone stamp, the quick sharp mask or brush etc, I can never seem to select just one pixel. The brush size is definitely set to 1 pixel but when I click on a pixel it also selects the surrounding pixels. I've tried adjusting the the brush hardness and spacing etc but nothing seems to help. I don't remember having this problem before.

Anyone know of this problem and a possible solution?

Thanks,

Jim

Magnify the image until the pixels become easily visible squares, then use the rectangular selection tool (marquee) to select the pixel of interest. I verified this works in Photoshop CS.

Thanks. yes I've tried this and it works.....just a bit of a hassle though. I thought that setting the brush size to a single pixel meant that it only paints on one pixel.

If you do it in-between pixels it will paint on them both. Try making sure anti-aliasing is turned off, which should solve the problem.

Selecting a single pixel is not a problem whether anti-aliasing is off or on. My problem is when I try and paint on a single pixel. For example I paint directly in the centre of a pixel with my brush set to 1 pixel and no matter what it paints on it but also three other pixels directly surrounding it, so four pixels end up getting painted on instead of one.

I meant to turn anti-aliasing off on the brush. I'm not sure how to do this in PS, try making Hardness 100%?

You would think that making hardness 100% would do this, but it does not; interesting, though frustrating behavior.

For painting on a single pixel (as opposed to selecting/changing a single pixel), use the pencil tool, set size to 1px and hardness to 100%. this does work in photoshop CS, can't vouch for earlier versions.

Thanks, that works. Should have tried the pencil tool first:)

If this isn't caused by 'feathering' I'll be really surprised - make sure it's set to 0, anything else will select pixels from the surrounding area and apply the effect in decreasing amounts: dead useful, except in this particular situation.

Change from BRUSH to PENCIL.

Sorry if someone mentioned this already ... about half way down I started skipping some responses. :)
