Also take this example.
This then expands on the isolation concept. By providing reflections and subtle shadows, while yet being 'isolated' this image gives the object(s) a place in the world, while still maintaining a single focal point.
So how to do we get this effect.
There really are only two options.
1) Spend forever in Photoshop =(
2) Spend a few dollars and get some of the following items.
+ Light tent - Wonderful for isolation. be sure to get some desktop lights to keep up the exposure levels.
+ Pure white serving and dinner plates. These remove the need to well remove the underneath of the object. Also leaving some wonderful soft shadows
+ Cheap A5 Photo Frame and white cloth - Remove the glass from the frame and have the object sitting on the glass. Have the cloth underneath the glass and running upwards behind to fill complete background of image.
Putting some to all of these items together can help minimize much of the time consuming post production process. Plus this can help with white balancing and removes unwanted distractions from the image.
Not every object works best with isolation, but they are definately worth looking into.
Note: i would like to give thanks for Maxfx and Pepo123 for some quality images to use within this Blog.
