Slightly confused about whether this should be in photography, cameras/lenses or here.

I seem to have acquired a hot/dead pixel. It's bright neon orange. Having googled, I have to point out that it's not when using long exposures; I'm working on trying to capture small birds in flight (that way lies madness) and am using speeds upwards of 1/1250th.

It's dead obvious in these photos, because I have a defocussed green background, but in other pics I can't find it at all, presumably because it more nearly matches the background.

I'm guessing all I can do is make a layer with a target around the pixel, and save it out as a transparent png so that every time I import an image from RAW, I put the png over it so that I can see and eliminate the pixel.

Is there anything I can do to easily find it in RAW - sometimes I haven't found it after five minutes at 200%? Or is there another way I haven't found yet?

(Yeah, I know the obvious thing is to buy a new camera, but that's out of the question ATM, especially with sales almost non-existent.)

Don't know what kind of camera you use but with mine I do a sensor cleaning with the lens cap on and the camera maps out the dead pixel then supplies that data with the raw file to ACR (LR does this too). Maybe that'll help.

I have something like 14 dead pixels altogether (5D Mk II).

Oh, mine is a 5D2 also. So I'll try that too. Tx.

Ooops, idiot question: once it supplies the data to ACR, what happens then, i.e. when you open the photo in ACR? Is it automatically magiced out?
