I've had my D3100 around a year now, and I dare I say a "toy photographer". I have recently changed from 6 inch to 12 inch figures, and I don't feel that I am getting the most out of my camera. Not only do I take photos of collectibles, I have 2 young children that I photograph often. The issue is not with the children, as most of the time I am outdoors with them and the light is perfect.
My issue is with indoor shots. I have a medium sized light box with two LED lights to illuminate. This isn't a problem if I'm in the direct light of my back door/windows, but once the evening comes (I'm usually at work throughout the best parts of daylight), my quality struggles immensely and the light is too "obvious" on the plastics. I'm using the 18-55mm lens that came with the camera, and a tripod.
Most of the time I use auto, but have been experimenting with different modes. I'd like to be able to capture the foreground and blue the background (not a problem with close up) but as soon as I zoom out to capture the whole figure, my lens seems a little fish eyed and does not capture the detailing. Should I be buying a new lens?
Thank you in advance for your time.
