White Dropper.

On this photograph I used White Dropper, to use that on photoshop you need to go to Images> Adjustments> Levels. It should look something like the second photograph when it comes up on your screen. The original photograph was very dark, you could barely see the pathway if Im honest, so the adjustments worked really well but I prefer how the original photograph looked. The sky was also a blue black color, but with the adjustments you can see the sky and that was not the point of the picture, It looked more mysterious and had an edgy feel to it.
