Layer of noise
Adds a consistent layer across the artwork making it appear as one image
Adobe Photoshop CS5 - Illustrated

18. Adding Noise with the Overlay Blending Mode
Methods to add noise
Create from existing pixels
Add to an image using the overlay technique
Not editable
Adobe Photoshop CS5 - Illustrated

19. Adding Noise with the Overlay Blending Mode
Understanding the Overlay blending mode
Viewing results of the Noise filter
Adobe Photoshop CS5 - Illustrated

20. CLASSROOM ACTIVITIES What is noise?
(Answer: Noise is a term used to describe a blanket of high-contrast pixels that produce a grainy effect over an image.)
Is Noise a good thing?
Adobe Photoshop CS5 - Illustrated

21. Sharpening with the High Pass Filter
Sharpness: corresponds to edges
Edges: image areas where highly contrasting pixels meet
High Pass filter
Effective at finding and isolating edges
Uses mathematical algorithm
Identifies where pixels of high contrast abut
Fills layer with solid gray
Except in the edge areas to isolate the edges
Adobe Photoshop CS5 - Illustrated

22. Sharpening with the High Pass Filter
Edges
Mostly involved in image blurring and sharpening
Blurring an edge
Reduces contrast where edge pixels meet
Sharpening an edge
Increases contrast
Provide heightened image focus
Adobe Photoshop CS5 - Illustrated

23. Sharpening with the High Pass Filter
Overlay/High Pass technique
Overlays an image on top of itself
Only at the edges
Filter fills the layer with 50% gray
Transparent when overlayed
Edge areas: those not filled with gray
Adobe Photoshop CS5 - Illustrated

24. Sharpening with the High Pass Filter
Applying the High Pass filter
Viewing the sharpened image
Adobe Photoshop CS5 - Illustrated

25. CLASSROOM ACTIVITIES
True/False. Edges are any areas in an image where highly contrasting pixels meet.
(Answer: True)
What does the High Pass filter do?
(Answer: High Pass is a filter that is very effective at finding and isolating edges. It finds edges using a mathematical algorithm to identify where in the image pixels of high contrast abut. It then fills the layer with solid gray everywhere except in the edge areas.)

26. Applying the Lens Flare Filter with Screen Mode
Bright spot often captured in the glass of a camera lens
Lens Flare filter
Useful for adding glints or bight spots
Must be applied to existing pixels
Can not be created in an empty layer
Adobe Photoshop CS5 - Illustrated

27. Applying the Lens Flare Filter with Screen Mode
Making lens flare a part of the artwork
Fill a layer with black and apply Lens Flare filter
Use Screen blending mode to make black areas transparent, leaving just the flare
Adobe Photoshop CS5 - Illustrated

28. Applying the Lens Flare Filter with Screen Mode
Positioning the screened
lens flare
Scaling down the size of the flare
The final effect
Adobe Photoshop CS5 - Illustrated

29. CLASSROOM ACTIVITIES

Creating non-destructive filter layers
Allows creation of filters on a layer
Can be shown, hidden, edited, and deleted
Called “smart filters”
Comes with a layer mask
Can be altered using an opacity adjustment or a blending mode
Adobe Photoshop CS5 - Illustrated

35. Applying Non-Destructive Filters
Created with a mask: filter mask
Functions like a layer mask
