Photoshop Masks
What is a Photoshop mask and what is its purpose?
A Photoshop Mask is a tool that allows you to selectively modify or hide portions of your image while leaving the rest of it untouched. It is extremely useful for non-destructive editing, that means alterations can be removed or adjusted without affecting the original image.
How does a Photoshop mask differ from the eraser tool?
Unlike the eraser tool which permanently removes parts of an image, a mask allows you to modify the visibility of portions of an image without actually deleting or affecting the original layer. You can easily unmask areas or adjust them as needed.
What are the different types of masks in Photoshop and how are they used?
There are two main types of masks in Photoshop: Layer Masks and Clipping Masks. Layer masks allow you to hide and uncover portions of individual layers. Clipping masks use the content and transparency of one layer to control the visibility of another.
Can you give a real world example of when you would use a layer mask and a clipping mask?
Layer masks are useful when you want to merge multiple photos together, for instance in creating collages. Clipping masks are commonly used to place an image inside a shape, text, or any other defined boundary.
