Creating Special Effects Photoshop learning and practicing Performed by doing one thing at a time Working in Photoshop Performed on a full-scale project Learning to look at the “big” picture Shift from one thing to an entire project Creative artistic sense and decisions Necessary along the Photoshop tools Adobe Photoshop CS5 - Illustrated

Using the Color Blending Mode Blending modes Mathematical algorithms Define how pixels affect pixels beneath them Create special effects Applied throughout many Photoshop features Prominent on the Layers panel Prominent in options with specific tools Brush tool Adobe Photoshop CS5 - Illustrated

Using the Color Blending Mode Base color Color of the original pixel Blend color Color being applied Result color Color produced by blending base and blend colors Adobe Photoshop CS5 - Illustrated

Using the Color Blending Mode Useful for colorizing monochromatic images Applies blend pixel hue to the base pixel Automatically affects base pixel saturation Adobe Photoshop CS5 - Illustrated

Using the Color Blending Mode No affect on base pixels brightness value Affects hue and saturation Adjustments panel Hue/Saturation colorize option Necessary to colorize a black-and-white image Sliders have no affect on a pixel with saturation value of “0” Adobe Photoshop CS5 - Illustrated

Using the Color Blending Mode Solid color blended over the image Painting in a layer set to Color mode Colorized image Adobe Photoshop CS5 - Illustrated

CLASSROOM ACTIVITIES True/False. The blend color is the color of the original pixel. (Answer: False) True/False. The result color is the color produced by combining the first two colors using the blending mode. (Answer: True) Adobe Photoshop CS5 - Illustrated

Using the Multiply Blending Mode Multiply mode Most common blending mode Makes blend pixels transparent Base art seen through that color Used when creating shadows and drop shadows Shadows in nature: always transparent Two important characteristics Multiplying black: always black Multiplying white: becomes invisible Adobe Photoshop CS5 - Illustrated

Using the Multiply Blending Mode Layers panel blending modes Grouped in six sections Intentional and specific Blending modes grouped on similarities Adobe Photoshop CS5 - Illustrated

Using the Multiply Blending Mode Color Burn and Linear Burn Two effective blending modes Similar to the Multiple blending mode Produce subtly different effects Color Burn increases contrast Linear Burn Creates multiply effect by decreasing brightness Adobe Photoshop CS5 - Illustrated

Using the Multiply Blending Mode Understanding the Multiply blending mode Multiplying a solid color Adobe Photoshop CS5 - Illustrated

CLASSROOM ACTIVITIES When you multiply black, what is the result? (Answer: It is always black.) When you multiply white, what is the result? (Answer: White always becomes invisible.) Adobe Photoshop CS5 - Illustrated

Adding Noise with the Overlay Blending Mode Blanket of high-contrast pixels Produces grainy effect over an image Visible noise: termed “grain” Low-quality images online Images downloaded to a cell phone Adding noise to “finish” a design Adds heightened sense of sharpness and focus Adobe Photoshop CS5 - Illustrated

Adding Noise with the Overlay Blending Mode Especially effective with multiple images used in a montage Challenge in a montage Making it appear to be one piece of artwork Layer of noise Adds a consistent layer across the artwork making it appear as one image Adobe Photoshop CS5 - Illustrated

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

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

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

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

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

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

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

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.) Adobe Photoshop CS5 - Illustrated

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

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

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

CLASSROOM ACTIVITIES True/False. The Screen blending mode functions as the exact opposite of the Multiply blending mode. (Answer: True) Discuss the difference between Screen blending mode and Multiply blending mode. Adobe Photoshop CS5 - Illustrated

Applying the Motion Blur Filter Motion Blur filter dialog box Used for blurring pixels Allows specification of a distance and an angle Results in a blur used to create the appearance of motion For both artwork and text Adobe Photoshop CS5 - Illustrated

Applying the Motion Blur Filter Viewing one motion blur applied Viewing two motion blurs applied Adobe Photoshop CS5 - Illustrated

CLASSROOM ACTIVITIES True/False. Photoshop offers only one blur filter. (Answer: False) Discuss the differences between Figures G-14 and G-15. Which figure conveys motion the best? Why? Adobe Photoshop CS5 - Illustrated

Applying Non-Destructive Filters Non-destructive adjustments Not applied directly to the artwork Adjustment exists on a separate layer Can be shown, hidden, edited, deleted Original artwork not altered Adobe Photoshop CS5 - Illustrated

Applying Non-Destructive Filters 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

Applying Non-Destructive Filters Created with a mask: filter mask Functions like a layer mask Applying multiple filters One mask remains available hiding or showing all of the applied filters Adobe Photoshop CS5 - Illustrated

Applying Non-Destructive Filters Smart filters can be removed from layered artwork at any time Temporarily Hide the filter Permanently Drag it to the Delete layer button on the Layers panel Adobe Photoshop CS5 - Illustrated

Applying Non-Destructive Filters The Grain filter as a layer on the Layers panel Viewing the filter applied with 80% opacity Adobe Photoshop CS5 - Illustrated

CLASSROOM ACTIVITIES What is non-destructive editing? (Answer: The adjustment is not applied directly to the artwork. Instead, the adjustment exists on a separate layer that can be shown, hidden, edited, or even deleted.) True/False. Smart filters can be removed from layered artwork at any time. (Answer: True) Adobe Photoshop CS5 - Illustrated

Distorting Images Distorted images used in artistic and practical effects Creating a sense of three-dimensional artwork Distort command Another transformation type Like scaling or rotating Adobe Photoshop CS5 - Illustrated

Distorting Images Skew, Perspective (Warp) commands Skew Perspective Provide additional transformation Skew Transforms art as though positioned on an angle Perspective Transforms art with a forced perspective Toward an unspecified vanishing point Adobe Photoshop CS5 - Illustrated

Distorting Images Distorting the artwork by moving the handles Viewing the final distorted artwork Adobe Photoshop CS5 - Illustrated

CLASSROOM ACTIVITIES True/False. The Distort feature allows you to move the four handles of the bounding box independently of one another. (Answer: True) Refer to Figures G-18 and G-19. Discuss what has been distorted in the artwork. Adobe Photoshop CS5 - Illustrated

Summary Learning to look at the “big” picture Shift to looking at an entire project Artistic sense and decisions for creating effects required with tools tools Blending modes Applied with many Photoshop features Prominent on the Layers panel Prominent options with specific tools Adobe Photoshop CS5 - Illustrated

Summary Noise: especially effective when applied with multiple images Color Burn and Linear Burn: two effective blending modes Non-destructive filters Created with a filter mask Functions like a layer mask Images distortion provides artistic and practical effects: sense of 3-D Adobe Photoshop CS5 - Illustrated
