Exercise 13 - Introduction to Lightroom Part 2

Keyboard shortcuts:
-Show filter bar - \
-Group into stack - Command+G

3 different ways to expand and collapse the stack:
-Photo > stacking > unstack
-Shift+Command+G
-Click on the little 4 at the top left corner of the image

When you collapse the stack, the images all come back together.

Create virtual copy of an image - Command+'

2. Clone stamp - D - Duplicate layer and use masking
3. Dodge/burn - D -Duplicate and mask
4. Merge Layers / Flatten image -D- Duplicate all layers and put them in a group and flatten remaining layers.
5. Paint brush - D - Create a new layer and use masking or duplicate layer
6. Cut part of image out from background - D - Duplicate layer / Layer mask
7. Erase Tool / Delete selected pixels - D - Layer Mask
8. Transform selection - rotate, screw etc - D - import as smart object
9. Flip Layer - ND
10. Flip Selection - D - open as smart object . select area and copy into a new layer
11. Convert to Black and White - D - adjustment layer
12. Save file from ACR -ND - save as DNG file
13. Apply a filter - D - Smart object
14. Change Layer opacity - ND
15. Change Bit Depth of Image- D - depends on what level you are changing from
16. Resize image - D - Open as smart object
17. Apply layer style - D - do it in Lightroom
18. Crop Image - D - Do it in camera Raw
19. Add adjustment layer - ND

Exercise 11 - Multi-Version PSD File

Steps:
1. Open image up in camera raw and make basic adjustments
2. Open into photoshop as smart object
3. Create a black and white adjustment layer and set the blending mode to 'soft light'.
4. Create a hue and saturation adjustment layer and bring down the saturation

1. How would you do the same thing using Lightroom ? You can do this in Lightroom by creating virtual copies of the image.

2. What are the advantages / disadvantages of each approach ?
Advantage of this approach is that it is easy to locate and saves disk space.
Disadvantage is that you need the software that created this document to view the copies.

Blending Modes

Using Blending Modes.


Creating Contrast with Blending Modes

Combining Images with Blending Modes

Lighter and Darker Blending Modes

Exercise 9 - Introduction to Lightroom

6. Click on the buttons at the bottom of the viewing area, to try different Library viewing modes – Grid, Loupe, Compare and Survey.
What are the shortcut keys for these ?
Grid: G
Loupe: E
Compare: C
Survey: N

11. Go to the Library Filter bar at the top of the viewing area. If it is not visible select ‘View->Show Filter Bar’. What is the shortcut key to toggle the Filter Bar ? \

12. Select the ‘Attribute’ filter button to display the attribute strip and use the attributes to control which images are displayed.
What three options are available for the Star Ratings attribute ? Greater than, Eaual to and less than.

25. Select the Develop module. What is the keyboard shortcut for this ? D

Exercise 4 - Colour Theory 2

1. To open up the previous image from exercise 3, the keyboard shortcut for opening an existing document is Command+O.
2. After changing the blending mode of the layer group to 'pass through' and making the background the working layer by selecting it in the layers pallet, fill the background with black. The shortcut key for this is Command+G.
3. Change the red circle layer and the blue and green layers' blending mode to 'lighten' and select the move tool. The shortcut is Command+V.
4. This simulates the ADDITIVE colour system.
5. After you change the blending mode to all of the colour layers to 'difference', this simulates the SUBTRACTIVE colour system.

Exercise 3 - Colour Theory

The keyboard shortcut for creating a new document is Command+N.
The size of the image in - Megapixels: 8.7 - Megabytes: 24.9
The shortcut key for the Ellipse Tool is Command+U.
The key that forces the ellipse to be a circle is Shift.
The shortcut key for the Move Tool is Command+V.
The shortcut key for fitting the image to the screen is Command+0.
The shortcut key for full screen mode is Command+F.
The colours that you see after you stare at red, green and blue and then look down onto the white canvas is blue (complementing red), red (complementing green), and yellow (complementing blue).
The shortcut key to grouping the layers in command+G.
After changing the blending mode to 'Pass Through', the complementing colours for Cyan, Magenta and Yellow were red, green and blue.
The final size of the image after it was saved was .1. MB which was vastly smaller than the initial image.

Exercise 7 - Smart Objects

Exercise 6 – Non-Destructive Editing

For this exercise we used Adobe Bridge, Camera Raw and Adobe Photoshop to edit Images.

1. Non Destructive editing definition: Ways to adjusts your images without losing information.
2. The four challenges introduced by digital photography are:-
-The creation of a vast number of photos.
-The need to apply identical adjustments to many photos in one operation
-The need to interpret a single source image in multiple ways
-The Desire to take advantage of rapidly evolving imaging technology to reinterpret images with more capable software in the future.

1. The term 'Derivative File' is when you duplicate files without compromising the integrity of the source image. i.e Adjustment layers
2. The 2 problems with using 'Save As..' to create derivative files is that it could become confusing with naming files and that it could take up too much disk space.
3. 'Self Referenced Non Destructive Imaging' is wrapping up the source image with a set of instructions for rendering a photo.
4. The 2 advantages of Self Referenced NDI over the use of Derivative Files is that it is more economical in terms of storage and it is easier to sort out to what has been done to an image.
5. Fixed Rendering - Refers to any image that has its rendering described in pixel information.
6. Live Rendering - A view of the image that only exists when the source image is loaded into the software.
7. The 3 advantages of NDI is:-
-Multiple photo manipulation
-Unlimited undo
-Space saving

Exercise 1 - Image Handling

3. Where do you store your image files long term ? (eg. Computer hard drive / External drive / CDs ?)

4. Do you use software to help organise your image files ? (eg. iPhoto / Lightroom / Bridge / File Manager ?)
File Manager

5. Do you shoot jpeg / RAW / both ?
Both

6. How did you display the images ?
Microsoft picture viewer

7. What software did you use to edit the images ?

9. How long would it take to find one of the images again ?
2min
