I am a newbie to digital photography. I am trying to take pictures of my wife's jewelry for eventual posting on our web site. I have a Nikon Coolpix 4300 which takes great pictures, but I'm trying macro photography and I can't get the lighting correct. I have two 100W lights with Phillips Natural light (blue bulbs) about 1 1/2 feet from the jewelry (to the sides). I have transleucent plexiglass in front of the lights to diffuse it. I am taking the shots in a closet and there is no other light source. Problem is that the various stones in the jewelry often come out different color than they actually are. The below photo shows orange stones, but the stones are a pink color with some white in it. I try shooting a series of photos, changing the f-stop setting each time. What is going on?
