There are some real pretty flowers that grow in the dark forested areas at TRNWR. I came across this Common Foxglove along the edge of the main path through the heavily wooded area. It was so pretty I decided to remove my camera body from the 400mm lens and use my 18 - 105mm zoom. I don't use that lens much, but decided that it would be my flower lens when I am able to get up close as it can focus at a much closer distance from the flower than I can with the longer lenses I use. I've found that I have to under expose a fair amount with bright flowers against darker backgrounds as the flower's color will blow out in areas.
