The Toolset in Photoshop7
The
Rectangular Marquee selects a rectangle or square area of your image Click
where you want one corner to be and drag your mouse down to the diagonal
opposite corner. As you drag, the marquee (the dotted lines) will resize
to the desired size. Holding Shift down while dragging will force Photoshop
to, draw a square marquee.
Round areas of your image can be selected using the Elliptical Marquee.
If you require perfect circles, hold the Shift button down as you drag
to constrain the width and height to equal values.
The Marquee tools are useful for selecting fixed shaped areas of your
image, but more often than not (particularly when you're working with
photographs) you'll need to have finer control in selecting the area to
get more irregular shaped areas. The Lasso tools allow you to create the
selection freeform, so, used in conjunction with the Magic Wand, these
tools are invaluable.
The basic Lasso tool allows you to click and draw the selection you want.
Wherever you
drag the miouse cursor is where the marquee will be. You can't beat this
tool for accurate selection of your image area.
polygon lasso
This variation of the Lasso tool defines the selection by creating a series
of points and joining the last one to the first one. Once the series is
closed, Photoshop will create a marquee by drawing straight lines between
the points.
Magnetic Lasso
If you have a clearly defined demarcation between the thing you want to
select and the surrounding content, you can use the Magnetic Lasso. As
you drag the mouse close to the
Magic Wand
selects all pixels of the same (or similar) colour. The Contiguous option
restricts the wand from only selecting adjacent pixels to the one you
clicked, as opposed to checking the entire image for that colour. The
Tolerance level dictates how close the colours need to be to the one selected
for inclusion in the selection.
Sometimes your image will
have areas you don't want. That's where the Crop tool comes in. Simply
select it, click and drag around the area you want to keep, and then
hit the big tick in the options bar to accept your crop marks. Everything
outside the crop marks will be deleted. The crop tool also allows you
to rotate your selection at the same time as you crop the image
The Slice tools
are used to prepare a large image for the web. When a web designer wants
to create an imagemap where one cohesive image is to contain several areas
that act as links or offer some other level of interactivity for the visitor,
they can use these tools to divide the image up into the right areas.The healing tool
The Healing Brush gives you the ability to selectively replace parts of your image with other parts. However, rather than simply cloning the source area, the Healing Brush combines the source and destination areas and the area around the destination area to provide an image which is as seamless as possible.
The Patch tool works in a similar way to the Healing Brush but for large
areas. You first select the area to be "healed", and then select
another area to source the "healing' from. Once you have your two
areas, drag one on to the other and watch the magic.
Brush
Probably the most widely used of all tools, the Paintbrush (or Brush for short) and the Pencil provide an enormous range of ways to draw on your image.
