DSS problem

Anyone know why DSS stacks my images just fine, and I adjust the RGB, luminance, and colour saturation o.k. but the saved TIFF image is monotone, no trace of colour at all? It doesn't happen if I use DSS on my old much slower laptop.

I never touch RGB, luminance and saturation in DSS, leave it alone. Plenty of time to play with that in Photoshop. So no i can't can't answer your question other than to point out it's not important. My saved TIFF files are always mono, and I convert them to RGB in Photoshop.

Hi Glen
I've had PS for well over a decade, and have never been able to get my head around it, have never really cottoned to computers. I was already 70 when I made the transition to digital imaging.I use JPEGs and in camera noise
reduction, and do my little bit of processing in DSS. My output TIFFS have
only recently become mono, and I can't see any way of changing it. They
are still colour on my older laptop.

Ok, if that has worked for you in the past it should still work. Did you upgrade DSS?

Perhaps something was changed...

I had a problem once (I changed settings un-intentionally) and my desperate way of fixing the problem was removing and then installing DSS from fresh... only then I found out what I have changed (it was automatic removal of hot pixels... big no-no! This results in all the stars look grey, and you had to have darks anyway).

Your problem may be RGB-calibration setting - it should be "Per channel calibration, I had problem with that once)

Thanks for the replies Glen and Bojan. After further investigation I have discovered that it is not saving the image in mono, but is in fact just saving
one of my original subs[ which in the selected part of the sky shows almost no colour] rather than the image resulting from stacking.
I have reinstalled DSS, and it does the same thing, so it would appear to be a problem with my laptop rather than DSS. Luckily I have an old laptop, so
can still use DSS, but much more slowly.

I have written up the simple DSS procedure for registering (aligning) filter Group output files:

I hope that I have explained this in a way that all can undertand. It is a technique I have used for years, and it always works.
