Mariposa tulip in the Sierra Nevada, Kings Canyon National Park



The Mariposa tulip blooms in the Sierra Nevada. We found this one along the trail in Kings Canyon National Park, on our Rae Lakes Loop trip in 2012. The term "Mariposa" is Spanish for "butterfly". The characterisitcs of these plants is that they have 3 sepals, 3 petals, 6 stamens, and one three-lobed pistil. The Mariposa tulip is in the lily family. The dark dots at the base of each petal helps to guide the bees that pollinate the flower to their nectar reward. In this image, the flower also has the shadow of an unopened flower stem crosing over the upper petal.

For photos like this, it's a good idea to use a low f/stop setting and a faster shutter speed. For this image, the settings were f/6.7, 1/350 second. The lower depth of field allows the background to blur so that the clearest part of the image is the flower you want to show. The fast shutter speed helps to ensure a sharper image in case of any slight breezes making the flower move. The closer you get to your subject, the more noticeable any motion becomes in the final image. Using a telephoto setting for the lens, allows you to move farther away from the subject, so motion is less noticeable. Some photographers use tripods and clamps to hold the flower stem still, which is a good idea. But, in this case, we were backpacking along a trail trying to make sure we covered enough distance each day. When we got this photo, we still had our packs on and just tried to get a good shot with the conditions as they were.

Remember, it's not just a picture, it's a story!
