Project 3 - Poster

Project 3 - Poster

For this project you are required to create a photo montage for an Advertisement. You will need to source a variety of images, and combine them to create an A3 sized composite image. Include wording and decorative elements in the layout which relate to the chosen theme and reinforce the imagery.

Non Destructive Editing

- Editing an image in such a way that the original image information is retained in the image file
- Allowing edits to be reversed or modified without loss of image quality
- Any editing performed is always working on the original image data, and not on a degraded or permanently altered version of it.

Metadata

Two Types of metadata:
1/ The unchangable information that is recorded by the camera
2/ Personal info eg keywords/tags/author


Metadata

Two Types of metadata:
1/ The unchangable information that is recorded by the camera
2/ Personal info eg keywords/tags/author

- Industry standard of metadata (Data Readable across programs)


Raw Files

- All cameras capture raw files
- Camera sensor types = CMOS
- CMOS : Comlementory Metal Oxide Semi Conductor
- CCD : Charged Coupled Device
- A brightness value for every photoreceptor (pixel) in the image
- Specification mapping the correct colour (ie. R,G,B) to each photoreceptor
- The pixel dimensions of the image
- Image metadata
- Other camera specific information

Wavelenghts of the following colours:

Red - 620-750 nm
Green - 495-570 nm
Blue - 450-475 nm
Cyan - 476-495 nm
Magenta - 380-450 nm
Yellow - 570-590 nm

Lesson 13 - Colour Management and Printing

Lesson 13

Colour Management and Printing

- Problems with under/over exposure eg exposing for highlights or shadows
- Generally expose to right of histogram
- Film - expose for shadows
- Printing - want a full histogram
- JPG Preview doesn't contain as much detail as the RAW


Calibrating a Printer

- Profile the printer
- Profile Paper
- Profile monitor
- Graphics card
- Different papers have different gamuts
- Different abosorption for paper

To Profile

- Print test target file
- Scan test target using calibrating device

Assigning Profile
It will leave the numbers the same but interpret the colour values differently

Converting Profile
It will change the values

Printing

- Flatter, convert to jpg or tiff
- Resize
- Images on photoshop canvas with correct resolution/colour space

Lesson 11 & 12 - Colour Management

Lesson 11

Colour Management

* Tutorial Demonstration by Geoff on Monitor Callibration


Colour Management
Device Independent Colour Space
- Device independent colour space has no dependence to device eg. RGB, SRGB
- Don’t relate to a particular device
- Typically used as a working space

Gamut
- Refers to Device dependant working space: eg RGB, SRGB, Pro photo
Profile
- Contains a colour gamut and information on how to convert another colour space into that gamut rendering intent

- Software: colour management module eg. Adobe
- We need to know the colour Gamut for each profile/device and how we can convert numbers
- Reference colour space

Colour Managed
- What the camera captures will be as closely represented as possible on monitor/printer
- The number will change

Working Space
- A space inside a computer to work on device

Where do we get profiles
- Default: comes with generic
- Create one: calibrate (custom profile)
- Canned profile (mostly for printer) – can download from internet for your particular printer/paper

Callibration
- Adjusting luminance/brightness/colour temp eg use of monitor controls
- Important to physically adjust monitor to what you want the closer the software can create a correct profile

Profile compensates for what isn’t quite right

Profiles are saved as ICC or ICM files

Soft proofing
- Previewing on monitor what it will look like when printed with a particular printer/paper

Rendering Intent
- When the gamut of source color space exceeds that of the destination, saturated colors are liable to become clipped (inaccurately represented), or more formally burned. The color management module can deal with this problem in several ways.

Unmanaged Colour Profile
- Non-colour Managed Profile leads to unreliable colour workflow
- Each device (camera/monitor/printer) interprets colour differently
- - Because each device has its own gamut

Gamut
- Device dependant
- The range of colours a device can reproduce
Can be represented by a 2d xy chromaticity diagram (LAB or XYZ)




- CIE (international Colour Standards) Colour space (xyz & lab)
- Device dependant Colour Space
- Any device that we can see colour can be shown on above diagram
- Additive device. Eg monitor
- Subtractive eg printer
- Printer has a small colour gamut

Photoshop
- View menu – Gamat Warning
- If it goes grey it means its not in the printer gamut

Lesson 10

Lightroom, Channels, Masks and NDE Cont.

Photoshop – Channels and Masks

Every Photoshop image has one or more channels, each storing information about color elements in the image. The number of default color channels in an image depends on its color mode. By default, images in :-
• Bitmap, Grayscale, Duotone, and Indexed Color mode have one channel;
• RGB and Lab images have three; and
• CMYK images have four.
Channels in color images are actually grayscale images that represent each of the color components of an image. For example, an RGB image has separate channels for red, green, and blues color values.
There is also a composite channel used for editing the image.

Lesson 9 - Blending Modes

Lesson 9

Blending Modes

A blending mode takes two colour values and combines them using a formula.
It is helpful to think in terms of the following colours when visualizing a blending mode’s effect:
• The result colour is the colour resulting from the blend as determined by the formula.
• The blend colour is the colour being applied with the painting or editing tool, or the colour in the layer to which the blend mode is applied (ie the Blend layer).
• The base colour is the original colour in the image ( ie the colour resulting from all the layers below).



Blending Modes are used in two situations :-
1. Painting Tools - To specify how pixels in the image are affected by a painting or editing tool such as the Paint Brush, Healing Brush, Clone Stamp, History Brush, Gradient, and Paint Bucket Tools. (The Blur, Sharpen and Smudge Tools use a subset of the Blend Modes.)
2. Layers - To determine how the pixels in one layer interact with the pixels in the layers below it.

Despite the great variety of blending modes, for the purposes of tonal and colour correction we tend to use just a few of them, as follows :-
- Multiply to build density,
- Screen to reduce it,
- Soft Light and Hard Light to increase contrast,
- Colour to change colour balance without affecting luminosity, and
- Luminosity to sharpen images without introducing colour fringes

You can reduce the effect of a Blending Mode by reducing the opacity of the layer.

Exercise 11 – Multi-Version PSD File


1. Select a RAW file of your choice.
2. Use ACR to ‘clean up’ the image ie correct any tonal deficiencies, straighten, crop
3. Export the image to Photoshop as a smart object.
4. Using non-destructive techniques create a layer set that creates a BW toned version of the image.
5. Create another layer set that produces a partially coloured / partially B/W version of the image.
6. You should now have three versions of the image in one PSD file.
7. Save the document as ‘Ex 11 – Multi-version-PSD.psd’
8. How would you do the same thing using Lightroom ?
By creating virtual copies of the source/original file and then applying adjustments

9. What are the advantages / disadvantages of each approach ?

Lightroom:

- Three diferent files which you can view at the same time

Photoshop:
- All versions in same file
- Saves space
- Cannot see all files at once
