So far, all of the work we've done in Photoshop had been in the RGB colour space.
Today, we're going to explore an alternative: Lab Colour.
This colour space uses three channels, but these are very different from RGB:
L = Luminosity channel
a = "a" colour channel
b = "b" colour channel

1) HOW LAB COLOUR WORKS
(source: http://www.photoshopbuzz.com/what-is-lab-color-photoshop/)
Most of our colour modes are based on how much of a certain colour is needed to be displayed for a certain device. For example RGB is how much Red, Green and Blue needs to be displayed to show the correct colour on a digital screen and CMYK values are for how much colour is needed for a 4 colour print. The LAB colour model is based on how humans see colour; How much colour there is on the green to red axis combined with how much colour there is on the blue to yellow axis, combined with a lightness value from light to dark. The diagram adjacent shows how this works:

3) LAB Colour Space Project
You will take TWO photographs for this project and will give them a similar LAB colour treatment as you did with the sample image.
CAMERA SETTINGS
Shooting Mode: Your choice
Other settings: Your choice
For best results, go somewhere that has an interesting variety of colours (not just white, grey, black, etc).
Make a real effort to take a nicely-composed shot. You do not need a person in your photos. Consider angle, depth of field, etc.
Your goal is to make your colours "pop" a little more and to possibly add texture detail. If the effect is a little too much, either reduce the opacity of your adjustment layers, or add a layer mask and selectively adjust areas of your image.
TO HAND IN:
Hand in before and after .jpgs (clearly labelled) to CLASSROOM. Don't forget the rubric!
