    • Ch 4: Painting Photoshop CS6 Essentials By Scott Onstott
    • Ch 4: Painting Understanding HSB Color • Hue is what we think of as colors of the rainbow • Saturation refers to how much hue is present • Brightness refers to the light intensity • Tints have full brightness but low saturation • Shades have full saturation but decreased brightness • Desaturated color is grayscale, having only variation in brightness
    • Ch 4: Painting Heads Up Color Wheel • You can select the HUD Color Wheel in the Preferences dialog box • On the Mac, hold down Cmd+Opt+Control and drag the left mouse button in the document window. • On Windows hold down Shift+Alt and drag the right mouse button in the document window. • The HUD Color wheel is useful for identifying complementary colors and picking any combination of saturation and brightness in the central color ramp
    • Ch 4: Painting Rotating the View • Press R to select the Rotate View tool (under the Hand tool in the Tools panel) • It is helpful to rotate the view when sketching with a pencil or painting with any brush tool • You can align the view to the arc of your arm or wrist’s natural swing when you are tracing a photo or painting in fine detail • Click Reset View on the options bar to rotate back to the default view 3D model courtesy of Google 3DWarehouse user Krzysio
    • Ch 4: Painting Eraser Tool • Use the Eraser to paint in the background color • The Eraser tool has three modes: pencil, brush, and block • Pencil mode is good for removing one pixel at a time • Brush mode supports partial erasure when the brush has reduced hardness • Block mode is good for erasing rows and/or columns while holding Shift
    • Ch 4: Painting Background Eraser Tool • Erases pixels leaving only transparency • Sampling: Continuous erases everything you paint over • Sampling: Once can be used to remove a single sampled color where you start the brushstroke • Sampling: Background Swatch removes the color in the background swatch no matter where you start the brushstroke
    • Ch 4: Painting Flow vs. Opacity • The Brush tool has flow and opacity percentages on the options bar • Painting at 100% in both flow and opacity doesn’t allow you to build up paint • Painting at decreased flow (top) builds saturation where brushstrokes overlap • Painting at decreased opacity is like painting with a wash (watered down paint) where overlapping paint has increased opacity
    • Ch 4: Painting Understanding Brush Controls • Brushstrokes are actually a series of copies of a shape made in the direction of the stroke • By increasing the spacing in the Brush panel you will perceive a staccato repetition of the shape along the brushstroke • Use Scattering controls to randomly reposition shapes along the brushstroke • You can randomize color with Color Dynamics controls
    • Ch 4: Painting Using a Tablet • The mouse is not a good input device for brush work (it’s like painting with a bar of soap!) • Pressure and tilt sensitive tablets are highly recommended for painting in Photoshop • Bristle tip brushes take advantage of tablets by allowing you to make a wide variety of marks by varying tilt and pressure, just like you might use a real paintbrush • The stylus is an absolute positioning device which is more intuitive
    • Ch 4: Painting Using the Mixer Brush • The Mixer Brush is the closest tool Photoshop has to a real paintbrush • You can treat the pixels of a photo as if they were wet or dry paint • The Mixer Brush can push wet paint around with or without mixing in new pigment • Toggle on Load Brush After Each Stroke if you want to mix in fresh paint and then adjust Mix percentage • Press Opt and sample an area to load that as new paint on the brush if you prefer Original photo courtesy of iStockphoto, ©Andrew Penner, Image #6376617
