Does NI help with hot pixels in long exposures?

Hi,

I'm very interested in NeatImage.

Does it also help with the little white "hot" pixels (and the big fat blue/red "stuck" pixels), that occur in long exposure shots?

Please see the shots at the following link:

Does NeatImage help clean up the slight long exposure noise? It is very slight, but depending on the subject, it can be very distracting.

Thanks,

Mike

No, Neat Image is not designed (yet) to remove hot pixels. This functionality will be added in the future.

It does remove high ISO noise, which may answer your second question, depending on the definition of "slight long exposure noise".

Pardon me if I´m too obvious, but I use an old trick to get rid of those anoyoing hot pixels...
Take a black shot (lens covered, same exposure time) after the original. You´ll get a black pic with only the hot pixels. Use this black pic in Photoshop to subtract/change color of the hot pixels... Worked well with a Sony 707 and a night sky.
Hope it helps!

Yes, it does. At least there are no problem with Canon S50 and shutter speed up to 15 sec. It absolutely cleaned the slight long exposure noise on night photos.
