Dark Frame software

[Astroman]

Hi all,

I am trying to find a free Dark Frame software that will remove hot/cold pixels from a batch (+300 frames) of lights, either in JPEG or RAW, but I also need it to resave the image either in the same or different directory. I am not interested in the stacking of the images.

Is there any software available to do this?

IRIS will do it.

You may specify as few as one light frame and multiple dark/bias/flat frames with deep sky stacker.

To get rid of cold pixels may require flats I believe.

I think DSS stacks the images also? I don't want it to stack the frames, just subtract the darks and resave them. Or it does do it but I haven't found out how yet...

I'll check out IRIS. Thanks

What I was thinking is that if you only specify one light frame then it is not going to do any stacking because it only has the one light.

It would only apply the bias/dark/flat adjustments to that one light frame.

From what you describe for so many frames you may want something that can do it all with scripts so you can let it chug away for hours rather than have to keep feeding it frames. I don't know if DeepSkyStacker can be 'scripted' or not. Some tools will allow people to make batch scripts. Have not progressed to the point of needing that just yet.

Thanks for your input, I had thought of doing it that way but yes, working with so many images it would take a great deal of time. If there was a useful way of doing this in photoshop without just subtracting the dark frames, but also removing the holes left behind, then that would be sufficient.

I will keep searching.
