Here is a very different type of image from Katahdin / Baxter State Park.
Both painted trillium and purple trillium are common in the northeast forests and both have a very small window of time during which they bloom, maybe three weeks. Purple trillium are more difficult to photograph because the flowers have a nodding presentation (the flowers droop over and face the ground).
What always catches my eye is groups of these flowers. Typically they are solitary plants, so a cluster of them is a nice find. For this shot, I used a wide-angle zoom lens with an extension tube. Without the extension tube, focusing distance is perhaps 14 inches. With the extension tube, I can get much closer to the flower, reducing the distance about 50%.
