Adjustment Layers

Adjustment layers are used to adjust images in separate layers so if something goes wrong the original image isn't ruined and lost and you can experiment with different techniques without having to keep reopen the image and start again. One layer can be used for each tool if you want to use more than one to adjust the image. So if you use one tool and get the image the way you want it, then use the next one and you don't like how it turns out you can just delete that layer instead of having to start again.

Hue/Saturation

Adding an adjustment layer and using the Hue/Saturation tool I have experimented changing the colours of parts of this image and have got the outcome of this image. I have shown the layers to show that I have one Hue/Saturation layer over the top of the background so if I don't like the way this image now is I can delete this layer and have my image back to how it was. I like the way this tool has changed the colours in this image and makes it look a little more dull but still has colour in it.
















Black and White

After experimenting with Hue/Saturation I deleted that layer and moved onto Black and White using a new adjustment layer. I have experimented with this setting and got the outcome of this image, I have made this image so that is it not all completely black and white, I have left some slight colour in her hair, and also using the pain brush I have removed the black and white in the ear to show the bright yellow colour in the ear plug, I really like this image and think that bringing some colour back into a black and white image works well.

Curves

Lastly, after experimenting with black and white I deleted that layer and adding a new adjustment layer moved onto using curves. I experimented with moving the curve bar around until I got it into a position to make the image look how I like it, I have given the image a little more light to make it bright, but not too bright and with this image I think it works well and isn't too bright.
