24. Lichen


  1. As you know, I never fail to be astonished by the sheer beauty and inticacy of lichen. Parts look like bubbling lava, and other parts resemble insect-eating plants. I am enjoying this Top 50.

    1. I agree astonishing. This one particularly appealed to me because of the variety of shapes in the one piece and the lovely contrast with the wooden stick it was growing on. I just wish had managed to get to few slightly out of focus parts in focus ... an impossible challenge without HDR though I think.

  2. HDR do you think? I know nothing about HDR. I look at this image, and the focus is upon the plane that is the bark of the tree, so the tree-hugging lichen is in focus, but anything sticking out from the bark is not in focus. To my mind, I would change the F-stop to one with a slightly longer focal length, eg F6.3 instead of, say, F4.5. But HDR might correct it, too. I do not know.

    1. I believe the idea of HDR is that it takes the image at different focal lengths and combines the images so the ultimately you get all the parts of the details in sharp focus. At least that is what they said in a magnificent book of wildflowers which had a very detailed close up shots of WA wildflowers.

      I think that HDR is also used to get a wider range of colours but the result in that case if often cartoonish colours.

The filmy veil of greenness

We crossed the border into Victoria cruising down a lovely timbered road before breaking into the rich dairy country of Gippsland. It is wonderful to see the land green after more than 10 years of very dry weather. But most of the state of Victoria is still drought declared.

The Pasture by Robert Frost
"I'm going out to clean the pasture spring;
I'll only stop to rake the leaves away
(And wait to watch the water clear, I may):
I sha'n't be gone long. You come too.

I'm going out to fetch the little calf
That's standing by the mother. It's so young,
It totters when she licks it with her tongue.
I sha'n't be gone long. You come too."

The end

I retire from the workforce this week and to celebrate have decided to retire my current blogs and start afresh with a single consolidated blog - My Bright Field - to record the delights of my new life adventure.
If you are interested follow me over there.  I will still be Sweet Wayfaring and collecting Royal Hotels.  The delights I discover along the way will appear together with my gardens and towns where I live.
