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


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



Base color Color of the original pixel

Blend color Color being applied

Result color Color produced by blending base and

blend colors



Color blending mode Useful for colorizing monochromatic

images Applies blend pixel hue to the base pixel

• Automatically affects base pixel saturation



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”




Solid color blended over the image

Painting in a layer set to Color mode

Colorized image

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)


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



Layers panel blending modes Grouped in six sections

• Intentional and specific

Blending modes grouped on similarities



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




Multiplying a solid color

Understanding the Multiply blending mode


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.)


Adding Noise with the Overlay Blending Mode

Noise 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



Noise 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



Methods to add noise Create from existing pixels Add to an image using the overlay

technique• Not editable




Viewing results of the Noise filter

Understanding the Overlay blending mode


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?


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



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



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




Viewing the sharpened image

Viewing the sharpened image

Applying the High Pass filterApplying the High Pass filter


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.)


Applying the Lens Flare Filter with Screen Mode

Lens flare 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



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




The final effect

Scaling down the size of the flare

Positioning the screened lens flare


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.


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


Applying the Motion Blur Filter


Viewing two motion blurs applied

Viewing one motion blur applied


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?


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



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



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



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




Viewing the filter applied with 80% opacity

The Grain filter as a layer on the Layers panel


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)


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


Distorting Images

Skew, Perspective (Warp) commands Provide additional transformation

Skew Transforms art as though positioned on

an angle

Perspective Transforms art with a forced perspective

• Toward an unspecified vanishing point


Distorting Images


Distorting the artwork by moving the handles

Viewing the final distorted artwork


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.


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


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
