Unless you're planning to spend all your time standing beside your finished piece with a task light shining at an optimum angle, it's a good idea to inspect it with light shone at various angles while it's still under construction.
This is especially true in carving, such as cabriole legs, lettercarving, shells, and anything in which you have to shape a piece with handtools. All will benefit from this kind of scrutiny.
I'll forewarn you...this is not an exercise for the faint of heart. Just when you think your fine skill has generated perfection, a readjusted light will make mockery of your workpiece and reveal with glaring clarity just how imperfect a creation you've painstakingly crafted.
However, it does give you the opportunity to make corrections and ensure that your work will look its best under any kind of light.
Even the type under which it will eventually most likely be found — boring, indistinct, overhead light. (See last photo....ew.)
