Photoshop

The photo taken last week came out to be quite yellow, so our group has decided to Photoshop them.
In our own time, I try out different technique to improve those photos.

This is my first edit, using the magic wand tool to select and remove the background, then auto colour the photo and add a white background behind it.
The problem of this is I cant remove the original background colour off near the hair.













 My second edit used auto colour, then selective and chose the colour to nature with black have the value of 40. However it still make the photo look yellow.

This is my last edit which i think the colour look quite well. To do this I have start with auto colour, then select colour balance set the value to -7 0 +8 and use photo filter, cyan to add the blue colour.
