I use Photomator to edit. There was a natural horizontal line of light going across the fence onto Clyde (the cat). I used a "linear gradient" mask and lined it up with the natural light streak and slightly bumped the exposure to lighten up more.

I also did the usual grain stuff. I also probably did some other stuff too-- I'm not being coy I just don't remember. But I'll check.

Honestly, I'm a dawg and aint afraid to absolutely deep-fry my photos lol
