I am a photographer and a guy so my knowledge and understanding of make up was zero until I started looking at photographs that looked great, what I have since learnt is that a little knowledge about makeup in relation to photography can really improve the look and feel of an image. I have found a few more tips online that i thought I would share.
Choose colors that look best in photos. Avoid pastels as these will wash you out. Colors the camera loves in makeup include reds, charcoal,emerald greens, golds and chocolate brown. Beige, tans and dusty shades do show up on the camera well.  Anything that is rich and deep in color should look good in a photo.
Exfoliate your lips. Unless you have the best editing team in the world, there is no way you can touch up chapped cracked lips in a photo. Warm your lips up with a washrag and apply any type of oil to your lips and buff away with a washcloth. Apply a nice layer of chap-stick to your lips to give them the dazzle they need.
Highlight for the camera. To add life to your face, swipe a highlight pencil(shimmery not glittery unless you want to look like fairy) under the arch your brow and blend it in with a brush or finger. Highlighting the inner corners of your eyes can help them look brighter and large. Draw a light line down the center of your nose and blend to define it for that shimmering glow.
Teeth. Swish with hydrogen peroxide, to give your teeth a healthy nice glow. You can also use lemons or baking soda for a all natural teeth whitener if you do not have any around. Remember not to get lipstick on your teeth and stay away from lipsticks that make your teeth look yellow.
Be sure to check your makeup prior to the shoot. That way you be reassured that it’s in good condition or you can quickly touch up anything not quite right.
For important events, such as a wedding, a career portfolio, a long-lasting family portrait, etc., seriously consider having professional makeup done. Explain to the makeup artist what the event is so that they can choose a look with you that suits the type of event.
