Thought I'd share some pictures of how that initial dio went together.
This was done indoors. I started with a dark grey blanket for the ground/background. Towards the back I bent the blanket 90 degrees using a radiius so it appears to go off to infinity. I like the dark blanket since it is very low key and doesn't attract the eye should any of it be visible in the picture. Also, since the main subject matter is brighter than the background the light meter of the camera will provide a better reading.
I then added diorama pieces:
This is followed by figures:
Next I added rubble:
Now you are ready to experiment with your camera. Play with camera settings, lighting, distance, angles etc. This first picture is taken with a direct flash. Note how washed out it looks and the figures have stark shadows directly behind them. I found the Build-a-Rama rubble has a little too much white material in it so it tends to be a tad too refelctive.
Compare the last picture to this one where the lighting is coming from a totally different direction. Note how the shadows look more natural and give the picture depth. It was this image that sent me down the path that lead to the pictures I posted. It took many more pictures with further tweaks to the lighting and angles to reach the final result.
Once you get a set of pictures you are happy with open up a photo editor such as Photoshop Elements. With this you can crop (cut out only the part of the picture you want). This is followed by correcting color and lighting and finally the image is resized for posting and voila
The camera used is a Nikon D50 with a Sgma 18-200mm lens on a tripod. The specfics of this picture are:
focal length: 200mm
f-number: 32
ISO: 200
exposure time: 6 seconds
Since this picture I have learned more about the use of small apertures (high f-numbers). While higher numbers do provide an increased depth of field the downside is diffraction increases meaning sharpness is lost. So there is a balance between how much depth of field you give the picture and sharpness. Other ways to improve the depth of field include reducing the focal length and increasing the distance to the subject. I'm thinking for this camera the sweet spot for the f-number is going to be in the f20-26 range. Increasing the aperture has a side benefit of allowing more light in and thus reducing the exposure time.
