Tools palette final

(13)Focus: blur/sharpen/smudge
Using the blur tool is just like painting with the gaussian blur filter. I often use the
blur tool to soften portions of an image or to locally modify an alpha channel mask.
The Use All Layers option is new to Photoshop 7.0. When you use the blur, sharpen
or smudge tool, it will read all the visible image data when adding blurred, sharpened
or smudged pixels to the currently active layer. Use the sharpen tool sparingly,
as excessive sharpening can create nasty image artifacts. It is much better to make a
feather edged selection of the area to be sharpened and apply the unsharp mask filter
instead. When the blur or sharpen tool is selected, you can temporarily switch between
one tool and the other, by holding down the Option/Alt modifier key.

(14)Toning: dodge/burn/sponge
Dodging and burning should be familiar photographic concepts. Photoshop provides
a nice element of control over the tool effect: you can choose to apply the toning
effect selectively to either the Highlights, Midtones or Shadows. Thus if you want to
darken or burn the shadow portion of an image without affecting the adjacent highlights,
choosing the burn tool in Shadows mode will enable you to do this. As an
alternative to the clone stamp tool, the dodge tool is excellent for removing wrinkles
and facial lines without altering the underlying texture if applied in very low percentages.
The third option is the sponge tool, which has two modes: Saturate increases
the color saturation, Desaturate lowers the color saturation.

(15)Type tool
The type tool allows direct on-canvas text editing. There are two ways you can use
the type tool: either click in the image window and begin typing – this will add a
single line of text – or you can click and drag to define a type box to which you can
add lines of wraparound text. Click on the Palettes button (on the far right in the
Options bar) to bring the Character and Paragraph palettes to the front of the palette
set. These provide full typographic control of the text.

(16)Shape tools
Photoshop can let you create shapes that can be in the form of a filled layer with a
vector mask (formerly referred to as a layer clipping path), a solid fill, or a path
outline. You can define polygon shapes and also import custom shapes from EPS
graphics, such as a regularly used company logo, and store these as Shape presets
using the Preset Manager. The shape tools are a recently added crossover feature
from ImageReady. Single pixel or wider lines can be drawn with the line shape tool.
To constrain the drawing angle by 45 degree increments, hold down the Shift key
(this applies to all the painting tools as well). Arrowheads can be added to the line
either at the start or finish of the line. Click the Shape... button in line tool Options to
customize the appearance of the arrowhead proportions.

(17)Eyedropper/color sampler
The eyedropper samples pixel color values from any open image window and makes
that the foreground color. The sample area can be set to Point, 3 × 3 Average, 5 × 5
Average. The Point option will sample a single pixel color value only and this may
not be truly representative of the color you are trying to sample. You might quite
easily be clicking on a ‘noisy’ pixel or some other pixel artifact. A 3 × 3 average, 5 ×
5 average sample area will usually provide a better indication of the color value of
the pixels in the area you are clicking. If you hold down the Option/Alt key, the
sample becomes the background color (but when working with any of the following
tools – brush, pencil, type, line, gradient or bucket – holding down the Option/Alt
key will create a new foreground color). The sampler tool provides persistent pixel
value readouts in the Info palette from up to four points in the image

(18)Navigation tools – hand and zoom
To navigate around an image, select the hand tool and drag to scroll. To zoom in on
an image, either click with the zoom tool to magnify, or drag with the zoom tool,
marqueeing the area to magnify. This combines a zoom and scrolling function. In
normal mode, a plus icon appears inside the magnifying glass icon. To zoom out,
hold down the Option/Alt key and click

(19)Selection mode/Quick mask
The left icon is the standard for Selection mode display. The right icon converts a
selection to display as a semitransparent colored ‘Quick mask’. Double-click either
icon to change the default overlay mask color. Hit ‘Q’ to toggle between the two modes.

(20)Orientation and canvas
Use the Image > Rotate controls to orientate your image the correct way up. For
example, you can rotate the image 90 degrees clockwise or anticlockwise, or by an
arbitrary amount, for precise image rotation.

ok that finishes all the tools here..
