Canvas
- Canvas is a new work place
- Canvas is in square shape and has width and height
- The units of width and height maybe Pixel, Inches, Centemeter, Millimeter,Points, Picas, Columns
- The canvas has a colour mode it may be Bitmap, RGB, CMYK, Lab Color and Greyscale
- The canvas also has a background content. It may be white or background colour we have selected or transparent.
Layers
- Layers are an important concept in photoshop
- Layers are
arranged in a canvas
- If we selected
the canvas content as Transparent, then there is no background (instead there
is Layer 0)
- If the top layer is fully covered the canvas, then we cannot see rest of the layer’s content under it. We can only see the portions of a background only through the transparent area of those layers above it.
Path
- Paths are not drawn as pixels, it is not a picture content. We can consider it as a vector content.
- It has multiple functions and can be discuss in our experiments later.
Opacity
- Opacity denotes how much opaque a Layer is
- It is measured in Percentage (in Photoshop)
- If opacity is 0% then the layer is transparent
- If opacity is 100% then the layer is best visible
- Here in the picture shows the White Colour of 3 Layers with different Opacity value
