·         Exercise 6 ‘Bad Image’ Review

·         Aberations

·         Major Project

·         Review of Assessments so Far

·         Test will be open book closed computer with calculators allowed

·         Bad Image

·         Open the image

·         Pressing ‘f ’key switches between view modes

·         ‘tab’ gets rid of pallettes

·         Press ‘space bar’ mouse becomes hand

·         Rotate image to be correct

·         Show rulers ‘Ctrl + R’

·         Show grid ‘Ctrl + ‘ ‘

·         Ruler tool to draw line

·         Information Pallette to get length and width

·         Image Rotation – arbitory

·         Image size  + 1cm to both height and width what happens?

·         Canvas size + 1cm to both height and width what happens?

·         Clone stamp tool short cut ‘s’

·         Align tool on keeps brush and alignment tool the same distance away always

·         Align tool off keeps the same constant reference point

·         Aberaitions powerpoint

·         Lens Aberations are an optical error

·         No les is perfect

·         Some aberations are wanted

·         Light is refracted as it passess through glass

·         Sperical surfaces fail to bring light to a focus

·         Stopping down can reduce this

·         In a cmera there are lots of parts to a lens

·         Each time light passess through the lens something different happens

·         Different colours may focus at different locations or plains and not together

·         Additional Structures are added to glass to try and fix this.

·         Side note – Tinyprints

·         White highlights can get coloured fringing

·         This is not reduced by stopping down

·         Can be fixed digitally

·         Coma is an off axis spherical aberration

·         Astigmatism

·         Distortion – Barrel or Pin

·         Image sharpness is not effected by these

·         Stopping down can’t reduce this

·         Geometric distortion

·         Edges are stretched by this

·         Curvature of a field – focused image is formed in a bowl shape – flat field lens

·         Can you determine standard corrections for your lens?

·         Major Project Handed Out

·         Ideas

·         - drink driving – ‘don’t turn a night out into a nightmare’

·         - Personal advert

·         - jeans adverts

·         - clothing adverts

·         - heels

·         - makeup with the before and after shots

·         Be sure to reference any work that isn’t yours

·         You need at least 2 of your own images

·         One image must be scanned in

·         It can be new imagery for an existing concept

·         Process

·         Brief

·         Research

·         Concept/Idea

·         Rough Sketches – Photo collection from research
