Using Levels

This is the image that i chose to adjust the levels to.

Firstly i selected the lake by using the "magnetic lasso tool".

Then i selected the lake.

then I on the layer i had just created I went to "levels" and made the lake a little bit brighter.

A histogram shows how much of the red grre and blue is in an image. you use one to make an image brighter.

If the image was correctly exposed then the histogram would be central in shape.

If the image was over-exposed then the image has too much light in it and the histogram will be uneven, with more of it being light.

If the im gae is under-exposed then the histogram will be uneven with to much darkness in it.

This is te final image after i have sorted out the levels.
