Trillium, Flower and Stem. Muir Woods National Monument, California. March 8, 2009. © Copyright G Dan Mitchell – all rights reserved.

A single trillium flower and leaves atop its slender stem in the redwood forest at Muir Woods National Monument, California.

I think I hit the peak of the “trillium season” when I visited Muir Woods near the beginning of March on a cloudy and damp late winter day on which the sun only occasionally broke through to light the forest floor. I probably spent an hour and a half photographing these flowers along a little section of trail that would usually take perhaps 10 minutes to hike – the flowers were everywhere. Some, like this one, were growing alone, while in other places there were small gardens of trillium flowers.

It may seem odd, but many of these close-ups of flowers were made using a 70-200mm zoom on a full-frame camera – no close-up lenses, no macro lens, and no close-up “filters.” The longer lens lets me work from a greater distance, simplifying tripod placement a lot, and also giving me a lot more flexibility in terms of composition. If there is are downsides to this approach they might include the potential for very narrow depth of field and the need to pay extra attention to camera stability. I used the “live view” feature to focus on many of these flowers. If the usual autofocus feature works I’ll use it, but sometimes it can be hard to get clean focus on these subjects. “Live view” on the Canon EOS 5D II raises the mirror and displays the image on the rear LCD. While the standard projected image can be useful for composition, it is not detailed enough for focusing. However, you can select a 10X zoom setting and see a very large and detailed image of the subject, and in this way you can do very precise manual focusing on any point in the frame.
