I used photoshop throughout my time at sixth form college, however within my first week at uni we learnt how to create a non destructive image. This basically is creating an image with multiple layers (Labelling them as to not forget where your up to with shape names), however instead of manipulating layers within photoshop by creating layer masks. This was a new process which I totally enjoyed learning.
CMYK- Cyan, Magenta, Yellow and Black
K=Key- as we wouldn't want anybody getting mixed up between Black Brown or Blue.
CMYK is used for print based graphics. The resolution for this type of work is 300 pixels per inch.
RGB- Red, Blue and Green, colours are used for web based design or digital format. These are the tones that distinguish each pixels, this type of resolution is 72 pixels per inch.
