Light is a Harsh Mistress

Like most people who use cameras, I find myself constantly bitching about the light. What a delight it is when you find yourself in the right place at the right time with the ideal light for your purpose. Of course, in the matter of light, good photography is largely a matter of planning in which one tries to be at certain locations under certain lighting conditions.

Trouble is, at this time of year (mid-summer in the southern hemisphere) good outdoors lighting is hard to come by and potentially ideal light is really only available for a few hours at the beginning and the end of the day. "WHAT?" .... I hear you say. "Look out there. The sun is shining. Bright colours are to be found in every direction. There is a lovely blue sky. Start shooting quick."

The pity is that these latter statements are just not true. At the height of summer, in the middle of the day where I live, the light is quite appalling for good pictures. The sun is effectively directly overhead for much of the day. This means that the tops of people's heads, the roofs of houses, the crowns of trees are all beautifully lit by the sun (from the direction of the sun) while the sides of all of those things (from the photographer's perspective) are composed of broken shadow.

The strength of the sun is such that highlights are extremely bright while shadows are very dark meaning that most idle pictures of the squinting relatives lined up at the beach barbecue are dominated by shadows which render the faces indecipherable. At the same time, the sand and all whitish objects are a featureless blown out haze. Terrific picture ... NOT!

If one were to shoot pictures between (say) 7 and 9 am or (say) between 4 and 6 pm, the situation is a great deal better. At those times of the day, the sun lights things from the side, enabling more saturated and consistent colours. Face your human subjects away from the sun and many good things start to happen. For a start they stop squinting in the glare, their faces and fronts are in consistent shadow allowing reliable exposure. Fill in flash can brighten the faces moderately and the whole picture improves out of sight.

In winter, the situation is much better. The sun is softer and comes from an angle ALL DAY. Highlights and shadows can BOTH be captured and the limits of camera dynamic range are not generally threatened. Most importantly, if you devote a day to go somewhere interesting for the purpose of taking pictures, you can keep shooting ALL DAY and take your time while doing so. You can get many more useful images of a location because you don't have to stop shooting between (say) 9 am and 4 pm and find some halfway useful thing to fill in your time meanwhile.

People who look at my "Photo a Day" gallery on Pbase will note that there is currently a paucity of scenic pictures. Most of my summer hobby images tend to be close ups and indoor locations because outdoor pictures are much too tedious to plan in what is presently a busy lifestyle.
