The SpyderCube is an ingenious solution. Here you can see better than with the gray and white card and the shadow region and the Highlights. Similarly, through the black case the pure black. A collaboration with CS3 and Lightroom is optimal. Either make reference photo in front of the original photo or to take pictures of the little thing does not even fall for a portrait on when the photo is still curtailed. Alone, the price is very high for the plastic cube.
