Bob,

All your photos from Lost Valley are great! I am unfamiliar with the Kenko Extension Tube Set - can you explain this to me?

Thanks David,
Extension tubes provide an inexpensive way to get even closer to your subject. They are designed to enable a lens to focus closer than its normal minimum focusing distance. The extension tube is mounted between the lens and the camera in order to create more distance between the lens and sensor. Doing this forces the lens to focus much closer than normal.
Hope that helps.

Bob,

This is your inquisitive friend again. I went to Lost Valley yesterday and the Hepaticas were in full bloom - both white and blue petals I think depending on the sun they were getting. I got some good photos as you did but my question is how do you know that they are the sharp-lobed species? I only found one leaf in the whole bunch and it was sort of in between round and sharp if you can visualize it.

Hey David,
From what I have read, sharp-lobed hepatica has leaves with three to seven lobes and sharply pointed tips. Round-lobed hepatica has three lobes and rounded tips.

I'm not sure if that helps, there were not a lot of leaves on the ones I found either, but I remember them being more sharp than rounded.

Bob
