In our free Photoshop tutorials step by step part 1 tutorial we had discusses about Photoshop tutorial free course, different term of Photoshop.
Marquee Selection Tool:
The marquee tool offers four different formats of above mentioned. Each format is use to select area of an image.
- Rectangular Marquee Tool makes rectangular selection (or a square, when used with Shift key.).
- Elliptical Marquee Tool makes elliptical selection (or a circle, when used with Shift key.).
- Single Row and Single Column Marquee Tool defines the border as 1-pixel-wide row or column.
Note: Press “Ctrl + D” key to deselect the selection.
# Specify one of the selection in the option/property bar.
- A -> New: selects or makes new selection or removing previous selection.
- B -> Add To: adds the new selection on the previous one.
- C -> Subtract From: subtracts the previous selection by new one.
- D -> Intersect with: intersects with previous selection.
You may smooth the hard edges of a selection by anti-aliasing and by feathering.
Smoothes the jagged edges of a selection by softening the color transition in between edge pixels and background pixels. Anti-aliasing is useful for cutting, copying, and pasting selections to create composite images. You may use Anti-aliasing for the Lasso tool, the Polygonal Lasso tool, the Magnetic Lasso tool, the Elliptical Marquee tool, and the Magic Wand tool. (Select a tool to display its options bar.)
Note: You can specify this option before using these tools. After your selection is made, you cannot add anti-aliasing.
Blurs edge is building a transition boundary between the selection and its surrounding pixels. This type of blurs can cause some loss of detail at the edge of the selection. You can define the feathering effect the Marquee tools, the Lasso tool, the Polygonal Lasso tool, or the Magnetic Lasso tool as you use the tool, or you can add feathering to an existing selection.
Note: The Feathering effects become apparent only after you move, cut, copy, or fill the selection.

To use the Rectangle Marquee tool or the Elliptical Marquee tool, choose a style in the options bar
Normal: It determines marquee proportions by dragging.
Fixed Aspect Ratio:
It sets a height-to-width ratio. Enter values for the aspect ratio. For eg. If you draw a marquee twice as wide as it is high, enter 2 for the width and 1 for the height.
For compose set values for the marquee’s height and width. Enter pixel values in whole numbers. In reinforcement to pixels (px) you can also use specific units such as inches (in) or centimetres (cm) in height and width values.
Refine selection edges
It helps to improve the quality of a selection’s edges and allows you to view the selection against different backgrounds for easy editing.
- Create a selection with any selection tool.
- Click on the Refine Edge in the selection tool options bar or click on Select > Refine Edge to set options for adjusting the selection:
It Determine the size of the region around the selection boundary in which edge refinement occurs. Increase radius to create a more exact selection in areas with soft transitions or fine detail, such as those in short hair or fur, or blurred boundaries.
Sharpens selection edges and removes fuzzy artifacts. Increasing contrast can remove extreme noise near selection edges caused by a high Radius setting.
It reduces irregular areas (“hills and valleys”) in the selection boundary, creating a smoother outline. Enter a value or click and drag the slider from 0 to 100.
It creates a soft-edged transition between the selection and its surrounding pixels. Enter the amount of value or move the slider to define the width of the feathered edge from 0 to 250 pixels.
