- 20. Adobe Photoshop CS4 LayerMasks Layer Masks are the most typical type of masking. They are pixel-based grayscale layers that conceal a portion of a layer from all visibility. Layer Masks are entirely based in the black/conceal white/reveal model. Each layer mask applies to a specific layer and that layer only. Examples of adjustments and special effects Brightness & Contrast, Hue & Saturation, Burning & Dodging, Sharpening, Vignettes, Working with filters
- 21. Adobe Photoshop CS4 Thebenefits (and limitations) of Clipping Masks Use Clipping Masks to mask away multiple layers with one easily editable mask. Limitations and odd behaviors: Clipping Masks, may not be applied beyond a layer group. IE: You may only mask the layers inside one layer group at a time. Clipping Masks do not rely upon the black/conceal white/reveal model we’ve learned. Instead, they apply all pixels of a layer to the mask. The Clipping Mask itself resides beneath the layers it is clipping, but you select the layers above to apply the masks.

Completely temporary An “advanced” selection technique similar in form to the Quick Selection Tool Uses the model of black/conceal white/reveal An advantage of Quick Masks is that they provide the gradients (levels of grayscale) provided by Layer Masks. Other selection techniques are pixel-on pixel-off. IE: no levels of transparency supported.

Digital image manipulation is a skill – like any other – that requires gradual & continual practice & improvement. Approach everything on a need-to-know basis, and don't worry about that which you do not yet understand. Stay upbeat! … but if you get frustrated, remember: You can always turn off the machine and walk away. :) Good luck. Best wishes. And get in touch if you need more help!

- #27 Use a simple pen tool exercises.psd , drag guides from the ruler to help you understand the way the pen tool works. Hold down the control key to edit paths? (Not if you have the path selected in the paths palette) use ducky.tif to experiment with clipping paths via vector masks. Set as clipping path. Save as photoshop eps. Place in indesign. ALSO: converting a type layer into a vector-based shape layer
- #29 go back and forth between simple playground experiments and drawing a goal. Pen Tool follow pen tool exercises.psd make sure to have students save as into their saved work folder so that we can use this later. Ctrl-click to end a path!
- #32 select a new image for students to work with. ASK: When resampling images, you can “upsample” or “downsample.” Which is the one you want to avoid as much as possible?
- #34 use a google search for “vanishing point photoshop cs4” to look at different examples.
- #37 Pass around book: adobe creative collection Students take pictures of teacher Should there be a photoshop level III? Plug Flash class evals

The Masks panel offers tools and options for creating editable pixel- and vector-based masks, adjusting mask density and feathering, and selecting non-contiguous objects. See Masking layers. Advanced compositing Create more accurate composites using the enhanced Auto-Align Layers command, and use the spherical alignment to create 360-degree panoramas. The enhanced Auto-Blend Layers command smoothly blends color and shading, and extends your depth of field by correcting vignettes and lens distortion. See Retouching and transforming. Canvas rotation Click to smoothly turn your canvas for nondestructive viewing at any desired angle. See Adjusting crop, rotation, and canvas. Smoother panning and zooming Gracefully navigate to any area of an image with smoother panning and zooming. Maintain clarity as you zoom to invididual pixels, and easily edit at the highest magnification with the new Pixel Grid. See Viewing images. Better raw processing in Camera Raw Apply corrections to specific areas of an image using the Camera Raw 5.0 plug-in, enjoy superior conversion quality, and apply postcrop vignettes to images. See Camera Raw. Improved Lightroom workflow Enhanced integration between Photoshop CS4 and Photoshop® Lightroom® 2 allows you to open photos from Lightroom in Photoshop and seamlessly roundtrip back to Lightroom. Automatically merge photos from Lightroom into panoramas, open as HDR images, or open as multilayer Photoshop file. Efficient file management with Adobe® Bridge CS4 Enjoy efficient visual asset management with Adobe Bridge CS4, which features faster startup, workspaces that suit the task at hand, and the ability to create web galleries and Adobe PDF contact sheets.

- #51 Open the 3 files in the photomerge folder. Use those to demonstrate these concepts, and then move on to the next demo on photomerge.
- #52 Continue working with Flower.psd Choose Select > Grow to include all adjacent pixels falling within the tolerance range specified in the magic wand options. contiguous Choose Select > Similar to include pixels throughout the image, not just adjacent ones, falling within the tolerance range. non-contiguous Modify http://www.webreference.com/graphics/column36/6.html
- #53 Continue working with Ranch House.jpg The Auto Contrast command adjusts image contrast automatically. Because Auto Contrast does not adjust channels individually, it does not introduce or remove color casts. It clips the shadow and highlight values in an image and then maps the remaining lightest and darkest pixels in the image to pure white (level 255) and pure black (level 0). This makes the highlights appear lighter and shadows appear darker. The Auto Levels command automatically adjusts the black point and white point in an image. This clips a portion of the shadows and highlights in each channel and maps the lightest and darkest pixels in each color channel to pure white (level 255) and pure black (level 0). The intermediate pixel values are redistributed proportionately. As a result, using Auto Levels increases the contrast in an image because the pixel values are expanded. Because Auto Levels adjusts each color channel individually, it may remove color or introduce color casts.
- #54 for the next set of slides use Flower.psd Analyze and deconstruct the layer fuctions in this document. A layer comp is a snapshot of a state of the Layers palette. Layer comps record three types of layer options: Layer visibility—whether a layer is showing or hidden. Layer position in the document. Layer appearance—whether a layer style is applied to the layer and the layer’s blending mode.
- #55 Lets use Lake(16bit).tif to create a hand-tinted effect photograph. Snapshots are similar to the states listed in the History palette, but they offer additional advantages: You can name a snapshot to make it easy to identify. Snapshots can be stored for an entire work session. You can compare effects easily. For example, you can take a snapshot before and after applying a filter. Then select the first snapshot, and try the same filter with different settings. Switch between the snapshots to find the settings you like best. With snapshots, you can recover your work easily. When you experiment with a complex technique or apply an action, take a snapshot first. If you’re not satisfied with the results, you can select the snapshot to undo all the steps. Note: Snapshots are not saved with the image—closing an image deletes its snapshots. Also, unless you select the Allow Non-Linear History option, selecting a snapshot and changing the image deletes all of the states currently listed in the History palette.
