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

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
