Picture taking is a hobby unto itself unfortunately
I agree with everyone with the Prof. You really need to activate your light settings based on the type of light that you are using. I have used normal incandescent lighting and natural lighting with my photos and you really have to try out all of the options to see what works best.
Currently I am using a single 100 watt incandescent because i have found that two lights provide a bit too much light and I have to increase the exposure on my camera anyway. I shine it from one side and put a bright white surface on the other side to reflect all the extra light. I put all of my miniatures behind a neutral grey background, which I find works better than white or any other colour (that being said, similar shades of blue work well also, as shown in the Prof's pictures in his blog).
Here is an example where I forgot to activate the colour correction for incandescent light:

http://www.blackbirdmedia.org/miniatures/?view=armies&which=gk&pic=10The second one looks much more like natural light, and makes the figs look better also! For those pictures I also turn on the macro setting as well as the vivid colour setting of the camera. The vivid colour setting simply turns up the contrast slightly, which can be done using your favourite photo editor as well.
So, you should try to experiment with different colour correction settings. If you are using the incandescent colour correction setting and your images turn out blue, then it is likely that you don't need the incandescent setting (as using that setting with natural light means that it will look blue!). In any case, hope that helps.
