Levels & Curves - Practice File

[johnb]

Hi

I think i have finally understood how to use levels and curves to process an image, however i have not got a decent file to start with, is there anywhere in the forum where there is a file that i can download to practice with - what would be really good would be perhaps a completed image to see how the beginners like me manage ?

Hi John

Try this file I uploaded for you.

Its the Pacman Nebula, 23x15 minutes of Ha taken with my Atik 314L+.

I used Photoshop to open and process the FITS file. Here is my processed version.
