The eyes can say so much about a person, they are the window to the soul. The eyes are also an open book for photographers. The revealing catchlights contain a lot of information about how the subject is being lit because the catchlights are a reflection of the main light source. Catchlights can reveal some very important information including the direction, shape and relative size of the lighting source among other things.
The creative photographer can mould or create a style of catchlight. Also, many manufacturers of light modifying equipment offer umbrellas with covered ribs so that they would appear less noticeable, as they can look like unattractive veins in people’s eyes. Some manufacturers offer attachments for soft boxes to make the resulting catchlights look like a window. What you do and how you do it is a matter of your imagination.
In this example as you can see despite the fact that the umbrella ribs are hidden behind the fabric they can be seen. However when this portrait is viewed at a normal viewing distance the lines are hardly noticeable and the lighting quite large and pleasing.
Personally I like the light source at 10 or 2 o’clock. When lighting a person be careful not to raise the light to high, darkening the eye sockets, leaving the eyes in shadow creating a raccoon effect. The eyes can say so much!
These are just some of my thoughts on flash photography, what are yours?
