Varying the brush size
To change brush sizes quickly as you paint, press the [ and ] (left and right bracket) keys. Press the [ key to reduce the size and the ] key to increase the brush size. The increment of change depends on the brush size. A brush size between 0 to 100 pixels will change by 10-pixel increments. A brush between 100 to 200 pixels will change by 25-pixel increments. A brush between 200 to 300 pixels will change by 50 pixels. A brush size between 300 to 2500 pixels will change by 100 pixels each time you use this shortcut.
Controlling the Hue Jitter
To change the foliage color as you paint, select the Color Dynamics option for your brush. You can change colors by specifying a Hue Jitter percentage. First, select a foreground color from the Color palette. Then enter a value for the Hue Jitter percentage in the Color Dynamics section of the Brushes palette. The larger the percentage, the more the hue will change as you paint.
If you want to better visualize how Hue Jitter works, change the Color palette display to HSB Sliders using the palette menu. Then slide the H slider back and forth to see the hue change.
Controlling Hue Jitter color changes
A good way to control the color changes as you paint is to choose the two colors that will define the range of color change. First, select a foreground and background color. The foreground color will be the main color. The background color will mix into the foreground color according to the percentage you specify. Select a percentage for the Foreground/ Background Jitter. The higher the percentage, the more background color will be mixed into the foreground color as you paint.
Removing perspective distortion with the Crop tool
You may want to remove a perspective distortion rather than introduce one. These distortions are common in photographs of buildings or other objects with rectangular planes that were photographed from an angle. You can use the Crop tool to correct the problem. Note that this correction only works on images that contain a rectangular object.
Select the Crop tool in the toolbox and roughly select the area to be cropped and corrected. The selection doesnt have to be perfect because you will adjust it in step 3.
In the tool options bar, select the Perspective option.
Move the corners until they align with the edges of the object that you want to make rectangular. These edges will become perpendicular after the crop.
Press Return/Enter to complete the action. Notice that the edges of the cropping area are now perpendicular to the edge of the image.
Converting unit values on the fly
You dont have to do the math to convert from pixels to points or from inches to centimeters, and you dont have to change your preferences. Let Photoshop convert values for you. When you enter a value in the tool options bar, you can follow that number with any of several abbreviations for units of measurement. For example, if you know the height should be 2 inches and the width should be 150 pixels, you can enter 2 in for height and 150 px for width. Following are the abbreviations that Photoshop recognizes:
|Pixels||px, pixel||Millimeters||mm, millimeter|
|Centimeters||cm, centimeter||Percent||pct, percent, %|
