Colour theory
· Colour models/modes
o RGB, LAB, Adobe RGB
· Electromagnetic spectrum – the visible spectrum. Short waves = blue, long waves = red waves, green in the middle.
o RGB additive colour system, eyes more sensitive to green. Rods and cones on back of the eye to see colour. Three different types of cones, one sensitive to each colour.
· Metamerism- if pure red and pure green light are shined in our eyes we will see yellow light because both types of cones (red cones and green cones) are both sensing the light and reacting.
· Used in printing and computers/tv’s
· Need to know!!!!
· LAB colour space – lightness, a red-green channel, b- blue-yellow channel
· Metadata- in the catalogue, file, XMP
o Cat- lightroom
o File- jpeg, TIFF, raw
o Raw- keeps camera info, setting details, date created,
o Raw file – image info, metadata, jpeg preview
o Propietory – owned by the company- CR2, NEF
o Open – can be edited/opened by anyone – jpg, dng, tiff
o XMP – bridge
· NDE
o Adjustment layers, smart objects/filters, layer masks, clone on to new layer
· Bridge – Broswer- doesn’t retain information – is a window into your file system. Whereas lightroom is the the opposite
· Lightroom
o Catalogue
o Rendering Engine – Allows you to see the changes that you’ve made on the image.
· Fixed rendering = derivative file, printed version, the colour of each pixel is defined and fixed.
· NDE – easily undone or changed.
· NDE – bulk editing easy
