In some cases, the image content makes it difficult (or at least tedious) to select by
color. The bottle image in this ad, for example, has only black colors — the bottle
is black, the shadow is a medium black, and the background is a mottled light gray.
Selecting by color range will almost certainly result in some of the selection intruding
into the bottle shape, and some of the background/shadow area being omitted from
the selection. The good news is that Photoshop has other ways for making selections,
including several that are specifically designed for selecting areas with hard edges.
Understanding Anchor Points and Handles
An anchor point marks the end of a line segment, and the point handles determine the shape of that segment. That’s

the curve above. When you drag a handle, the connecting B1
segment arcs away from the direction you drag.
