As we said earlier, there are many selection options in Photoshop CS6, each with its
own advantages and disadvantages. You have already used the marquee tools and lasso
tools to select general areas of images.
Many images have both hard and soft edges, and/or very fine detail that needs to
be isolated from its background (think of a model’s blowing hair overlapping the title
on the cover of a magazine). In this type of image, other tools can be used to create a
very detailed selection based on the color in the image.
Rather than simply deleting pixels, as you did for the lightning image, another
option for isolating an object with a path is to create a layer mask that hides unwanted
pixels. Areas outside the mask are hidden but not deleted, so you can later edit the
mask to change the visible part of the image.
