Tutorial on Using ACDNR

[twade]

To all,

I just published a new tutorial on using ACDNR.  It's geared towards film images, but works well with CCD images too.  You can find it here:

Wow... that's awesome. Thanks Wade for this great tutorial.

Carlos,

Thanks!  I'm glad you found it useful.  Eventually, I plan on updating my flat-fielding tutorial using the great new tools in PixInsight Standard.

Excellent tutorial, Wade. I highly recommend it.

I look forward to your renewed flat-fielding tutorial.

Hi there.  Sorry to dig up this old thread, but found this tutorial very helpful in understand the noise reduction techniques using PixInsight.

One question (for the moment) is when to apply it.  Been trying to understand what tools to use when the data is linear as opposed to after the data is stretched.  eg just read about deconvolution best applied when data is linear.

So should this noise reduction be applied at linear stage or right at the end?  What stage of your workflow?  Last, then some output sharpening?

I'm glad to see you found it useful, despite its age.   

I apply noise reduction to a non-linear image (i.e. after the first or second histogramTransform).

Thanks mate.  I had assumed that, as it appeared in your example that the data had been stretched already, and also I found much better results after stretching, but just thought I'd get it confirmed.
