Hi, welcome in new episode about processing your astrophotography in PS
Lets go !
Today i will work on background, noise reduction
If you havent astronomy tools CS2, then its special for you
But if you have, then dont turn it off ! Use those parameters i pointed in here !
Ok, begin from our photo
Photo that you can see, is made by jolo from ForumAstronomiczne.pl
Before i changed curves and levels,
It s totally fresh image, i just wanna show the process of reduction
Click Ctrl+A and Ctrl+C, but before you have to extract the color from background, use pipette
Click: File -> New, PS will change size instantly for your copy
Now you can see white workplace, click Ctrl+V
As you can see theres not changes
Copy layer
and choose this one tool i clicked
use it on photo, just like i did
now pick Filters -> Noise -> Add noise
Values : 1%-2,5%, also you can change other options but i mostly dont
Now again use Ctrl+A Ctrl+C
Ctrl+V and pick Lighten on layers
As you can see we lost a little detail, also did noise
If you want your detail back pick Brighness/Contrast
Then Brightness to about -25
And use curves to draw picture
Without any noise ! I hope that YTs bitrate will let me show you changes before and after.
I think thats it, so see you later guys, ask any questions in comments ! :)
