Speziell für die A1 programmiert. Ich hab's noch nicht getestet, aber...:
HotPixel is a Photoshop-compatible plug-in designed to remove "hot pixel" noise from digital images.
"Hot pixel" noise often occurs when taking a photograph with a digital camera using a long exposure in low light situations. It appears as coloured spots of around one pixel in size.
This filter allows automatic detection and removal of these hot pixels without degrading fine image detail. It should work on all but the most noisy of images.
This filter is free to use.
