Sometimes, simple is better. Most of my fine art photos are low-key photos, meaning that they are dominated by dark tones. This is an example of a high-key photo where it is predominately made up of light tones. The result is a simple elegance and a very light and airy feeling.
From a technical point of view, lighting and processing are really quite simple. You need to be a little careful with exposure if you’re using an automatic exposure setting on your camera since it will tend to underexpose the image. You also need a good monitor that’s properly calibrated so that you get an accurate preview of how the image will print.
