Jack in the pulpit full frame (1 of 3)
Arisaema triphyllum, a native of midwestern forests. One of a whole tribe of Jacks living up on the SW hill side.
This ground layer plant is catagorized as an ephemeral because they come and go, playing a transient role in the life of the forest.
If the plant is properly dried or cooked it can be eaten as a root vegetable. If not properly prepared it is poison (burning in mouth and gut, sometimes serious swelling).
The clarity of photos properly made with a large sensor and a good lens makes identification much easier.
This image was shot crouched over and hand held at 1/30 sec at f 2.8, ISO 100, at the 70mm reach of the the 24-70 sigma zoom lens on a Sony A900.
When I want to get the best photo quality in terms of sharp, crisp and clear details, I shoot at ISO 100 or lower. Using a higher ISO begins to show when you enlarge images looking for good detail. In film it was graininess, in digital it's more like fuziness.
