Newbie DBE question


Recommended Posts

Hello everyone.. ok, so i extracted a background to fix some awful vignetting from my DSLR following a tutorial that i just saw is almost 10yrs old.. background extracted great but now.. how to i subtract it from my image?  

Be kind, i'm an AP virgin... :)

Pixinsight should have generated 2 new images if you have certain boxes ticked. One with the background its calculated and another with the same background subtracted from your master frame. Pixinsight by default doesn't overwrite masters. It always creates new images.

I sorted it... i needed to select to apply the subtraction or division of the extraction to the image.  Thanks.   Tried to delete this post but couldn't find where.
