Flash = bad! :danbanna :danbanna :danbanna
I stopped using flash long time ago (even though I did a short experiment with a ring flash), and when I DID use flash, it was always BOUNCE flash and not pointed directly at the model...
Here's a suggestion... I am assuming that you have a camera tripod when I say this...
Have one light shine down on the model. Have the other light illuminate from the side. Experiment with the aim of the lights to minimize reflections and 'hot spots' that the camera sees. Next, turn the flash on your camera off. Set the camera on Aperture Priority setting and set the f-stop to the highest possible setting in order to maximize your depth of field. The camera will give you a long exposure time, but the end results will be more to your liking, I predict. If you don't have a remote shutter release, utilize the self timer feature to release the shutter in order to avoid camera shake and the resulting blurring of the pic. Take different pics with different lighting arrangements so you get a good variety to choose from. Next, it's off to edit them...
Once you import the pic into Photoshop (or other editing program), you will most likely find that it appears flat and underexposed. No problem. Create an adjustment layer for levels and adjust the highlight slider to the left until the highlights brighten. You may have to read up on adjusting levels in the documentation. After you get a good Levels layer, create another adjustment layer and adjust hue/saturation until you get a result you like. Then, duplicate the background layer and, while it is highlighted in the layer menu, go into filters and perform an Unsharp Mask. Keep the radius and threshold values very low, but play around and see what it does for you. Too much unsharp mask is not a good thing.
As I have mentioned many times before, you can only do so much with the camera itself. You can adjust the lighting to get good balance, just the right shadows and minimal glare, but at some point you will have to edit the pic on computer in order to take it to the next level.
And that, folks, is my :mine worth!
