·         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

·         Colour Temperature and White Balance

·         Degrees Kelvin Scale

·         1000K – candle

·         2900K – 100W tungsten light bulb

·         3300K – tungsten

·         5000K – Daylight/ Flash

·         7000K – Shade

·         9000K – Blue Sky

·         If my light source is a lower temp than what my camera is set to it will be a yellowey orange colour

·         If my light source is a higher temp than what my camera is set to it will be a bluey green colour

·         Sharpening will not focus an image

·         Unsharp mask – 300 - 0.4 - 2/0

·         Abberations –

·         Adobe Lightroom 3 develop module handed out

·         Exercise Lightroom import – develop – export handed out work through

20-03-12 and Question 3

Technology 1 - Computers     20-03-12

Brian Miller                                  Week Six                            Semester One

·         Common graphic file formats handed out

·         File formats specific to programs

·         Filename.extension

·         TIFF  - tag image file format often nice of BITMAP and GRAYSCALE images

·         EPS – encapsulated post script files – to retain duotone it must be saved as EPS

·         GIF – Graphic interchange format

·         JPEG – Joint Photographic Experts Group it compress’ a file – throws away information

·         PNG – Portable networks graphic files lossless compression file

·         PDF – portable document format

·         PSD – photoshop document file

·         Exercise 5 – file types and sizes handed out

·         Continue to work through this and blog question 3

·         Question 3.

A) explain the differences in the sizes of the two tiff files in steps 1 and 2.

        One of the tiff files is compressed causing one to be smaller

        B) when saving a jpeg file what two things change when you select a different quality factor?

        The size of the file diminishes

        And the quality diminishes – pixels got larger as file type shrunk

        C) what is dithering and why is it used?

        Dithering is where you duplicate tonal gradation from the original where there are less colours to use

        D) explain the difference in size between the greyscale tiff file and the original tiff file.

        The greyscale version has less channels making it 1/3 smaller

Artifact – something in an image that wasn’t in the original

When a JPEG is over compressed it gets

Blocking

Artifacts

Loss of detail

·         Image histograms

·         Graph to show how many pixels there are for each brightness value

·         A histogram can be shown for each channel

·         There is never a generic histogram

·         High key/white/bright image – lots of pixels at the white end

·         Low key/black/dark image – lots of pixels at the black end

·         Low contast image – many pixels in the middle of the image

·         Other images

General adjustments

                Brightness

                Contrast

                Hue

                Saturation

                Levels

                Curves
