Knowing good stage makeup techniques is important for those that spend time under bright lights and in the public eye.
Stage Makeup Techniques

You might be surprised to know that stage makeup isn't just for those performing in plays. Stage makeup techniques are used by celebrities in both film and television, as well as television personalities like the anchor on your nightly news station or on your local weather channel.

Why Stage Makeup
Stage makeup is necessary for a few reasons. Here's why:

The bright lights used for plays, television, and movies tend to "white out" the faces of the actors and actresses. This can make it difficult for those watching to see facial characteristics and expressions, which can be very important for the story line being told or performed.
Ascetically speaking, stage makeup improves the way actors and actresses look. This is considered preferred in nearly all entertainment industries.
At times, stage makeup can be used to alter the appearance of an actor or other individual in order to portray a certain image or fulfill the qualifications of a certain role. There have been men made to look like women and vice versa, as well as changes in skin color and tone, and other drastic changes - all through the use of professionally applied stage makeup.
Important Stage Makeups
Stage makeup techniques vary, but generally include a few basic steps. Here are a few things to remember when applying stage makeup.

Foundation and concealers are useful for evening out complexion and for eliminating shine. This is especially important if you have red tones in your face that will be highlighted by the bright lights. A yellow-based concealer can help with this.
Contour: Adding contour to your face will make up for the "white out" effect of the lights. Adding contouring and shadows to your cheeks and brow will help define these areas. You can use a darker cream foundation or a bronzer to create this affect. Apply makeup to the brow bone and cheek bones to achieve facial contouring.
Color: By adding color, you can achieve a healthy glow while you're under the bright lights. Apply blush liberally along your cheekbones. Eyeshadow should dust both your lower lid and brow bone. Lipstick should be a shade or two brighter than you'd normally wear, as the lights tend to tone down the look of makeup.
Eye Makeup: In addition to eyeshadow, both men and women generally need to wear eyeliner to help define the eyes. Additionally, mascara can help to bring light lashes out amid the lights.
Techniques to Know
The following techniques are useful for applying stage makeup.

Apply makeup evenly, but heavy. You will need to apply much more than an individual would usually wear.
Use a sponge or makeup brush to apply base, coating face and neck and evening out the edges with a cotton ball or wedge. Powder will finish off your base by removing shine.
Add color, such as blush or bronzer, on the apples of your cheeks. If you are attempting to look younger or fresh faced, add just a little color to the tip of your nose, as well.
For elaborate makeup looks, such as a total face color change, apply stage makeup beginning near your forehead, working your way down with the makeup sponge or brush. It may require several coats, especially if you are trying to turn the face white, like a mime or other character.
If you need to wear a wig for your part, be sure to blend makeup beyond where the wig meets your skin. This will make the look appear more natural.
Apply eyeliners well beyond your lash line to create a dramatic look. This is also a good way to add an exotic appearance to a character's look.
