I think the word is "deffo"
When I see a photo of which I think that it would be interesting to see how it would look with a few tweaks applied I drop it in my editing software to try it out. Just right-click>copy and 'paste as new image' in the software. Once you're done you can simply close it without saving and it's gone again. Useful exercise too. So I gave this one a try and I must say that it will look much better with a few tweaks to the histogram/luminance channel. You should definitely try that out.
When in doubt..... Press the shutter.
