Photoshop session 2

RGB - Red/Blue/Green



These are the primary colours that make up an image.


With all these colours together it makes white, and the colours created by mixed certain colours together, e.g. Blue and red, make purple, and this colour would be known as a secondary colour.


In Photoshop the primary colours can be found in 'Channels'. This is where all 3 colours are broken down and can be worked on individually if needed.


















When finding levels you go to Image - adjustments - levels :

Levels                                                      

Levels increase the contrast of the overall image and helps you to understand the tones so you can get the best of the colours in the image.


To the right is the pointer for the darker tones if needing to be mind darker of lighter, and the right hand tab is there for the lighter tones.


A good saying to remember is bring the boat into the shore.

                                                                      Curves

The curves tool can take input tones and selectively stretch or compress them. a tonal curve is controlled using any number of anchor points. The result of a given curve can be visualized by following a test input tone up to the curve, then over to its resulting output tone. A diagonal line through the center will therefore leave tones unchanged.

                                  Layer Masks


A layer mask is a layer that is over your image but it is reversible and can be done and undone very easily. Though the use of black, white and grey you can make your layer as opac or solid as you like.

Here i have my layer and background image

Then you click the layer mask button to reveal all of the image, meaning that the mask is off and nothing is hidden

Grab your PAINTBRUSH. Choose BLACK to make soming disapear, Layer masks are not destructive so just change the colour to WHITE and paint over the image and it’ll reappear. The different shades of black.grey/white you use will alter the opacity of the image.

     

     

By pressing X on the keyboard you can quickly switch between black and white in your painters pallet: 

Through using grey with the paintbrush it has made the layer opaic so you can see whats underneath.

Adjusting layers

                                    

When you want to adjust your layer you can go to adjustments and change whatever you need to, whether it be levels, contrast or shadows.
