Can anyone tell me whether Photoshop Elements is capable of dark frame subtraction?

Thanks,

Never use jpeg to do all your processing of your images on. JPEG is a lossy compression image protocol which reduces the size of the images by taking out data using a weighted or averaged, nearest neighbour interpolation and reduction of the numbers of pixels present in an image. You lose resolution and (sometimes) colour depth when that happens. It may take a little longer to process, but use FITS, TIFF's or RAW files to do all your processing on, then create your final images as jpegs, or better still, PNG files. PNG files are lossless files, so you don't lose any information from the files when they're created.

Liz,

I've tried several software packages like Gimp, Photoshop, etc to do my processing but I now almost exclusively use StarTools. It has everything I need, is easy to use and will produce images that I could only dream of when I was using Gimp and Photoshop. That's not to say I couldn't produce the same image with those software packages but it's a hell of a lot easier using StarTools!

Just my 2 cents worth!

Cheers,
Mario
