Astophotography Stretching

Recommended Posts

I am totally new to Affinity, prev used Photoshop, which since the Catalina upgrade no longer works, and was equally new to stretching astrophotos until recently, but in PS this entailed using the 3 tabs under the histogram to bring out the detail. In Affinity there seem to be only 2 equivalent adjustments (or so it seems to me), the black level and the white level. Therefore is it possible in Affinity to stretch the histogram? By stretching see the first part of this You Tube video if that is allowed here.

Hi @extremenewby, on Affinity Photo's Levels adjustment dialog you'll want to use the Gamma slider as an equivalent to Photoshop's mid-point slider.

If you have any other questions about editing astrophotography please ask, I've been working with various deep sky imagery lately and adapting various techniques to an equivalent approach in Affinity Photo. Hope that helps!

I have an add-on question to this topic.  I too have been trying to adapt PS processes to Affinity.  In many PS tutorials that address stretching for astrophotography they do it in increments, a little at a time.  Does this concept work in Affinity as well?  I've seen some amazing images that have come out of PS that I just can't seem to recreate in Affinity.
