I recently starting using a lighting kit for photographing my daughter. I am totally new and am learning every time I use it. The kit I have is here. I have been taking pictures with the lights standing about 5-6 feet back from the subject. This is the only decent light in this room and the pictures have been coming out fairly dark like you can see below. For the picture below, I was using a Nikon D70S with the kit 18-70 f/3.5-4.5 for the photo below; I used about a 35mm DX focal length. Since then, I have purchased the Nikon D90 and a Tamron 28-75 f/2.8. This new equipment should greatly help with the lighting as I am now at a constant 2.8 and can bump up the ISO a little without any loss of picture quality. My question is though, for pictures like the one below, is 5 ft too close/far away for my setup in order to get pictures that really 'pop'? As you can see in the picture below, I have been forced to use on board flash which in turn produces nasty shadows. What would be the best setup to get a bright picture without the shadows utilizing my current equipment? Should I get an external flash such as SB-600 to help with this setup? Any help is appreciated.
