How do I write out image that has been edited with Node Editor?

Hi I tried exporting the edited image but the output Image looks completely different, what output format should I render it with to get it correctly. Input and file colorspace both are linear
Here is how it looks https://imgur.com/a/jNKDIUj

Your viewer is set to ‘sRGB’ while your output file is written out as ‘linear’. That seems to be the mismatch. My best guess is: Set your write node property ‘File colorspace’ to ‘sRGB’ as well…that should do the trick!

Happy compositing!

oh nice that really solved it thanks
