Why and how were the images edited? My UK Film - No More Room In Hell

A few of the images chosen to be in my final booklet had editing techniques added to add a more negative look for the final document. The reason for editing the images is so that they all follow a similar moody look which would flow consistently throughout the booklet. Examples of this are that some images dark and moody which was the theme I was going for, but the ones that needed editing were too dark for the images to be recognisable. Theses changes i had to make as they didn't suit my film.

Before and after screenshots of the editing process on the images.

1. The Face

The original photo was too dark and could barely be seen, so I increased the brightness and slightly increased the contrast which make it more visible, but in return gave it a red-ish tone which could give the audience a dark and negative atmosphere which i want.

2. Barn

The original was too dark like The Face photo, so the image's brightness and lightness was brought up as well, giving of the light look, as if it's a torch.
The other editing technique i used was crop. I cropped the image slightly, taking out the hay which was on the left side.

 3. Ben

Originally ruined by another person, this image was deemed useless before editing,
but after cropping out the other person and making negative space for text, the image was now useful,
the image was intentionally blurred to add a more edgy look.

4. Fire

For this image the saturation was increased to make it more red and sharp, and the exposure was also slightly increased to make the fire seem more red and sharp.

5. Light

This image was edited to add more reds to the image, whilst taking away more of the darkness, this gave it more of a red background, giving the idea that it's giving off warmth. The saturation was also increased.
