Fog, San Francisco, Dawn

December 20, 2010 G Dan Mitchell 4 Comments

Winter fog illuminated by dawn light engulfs the skyline of San Francisco.

The conditions changed radically during the half hour or so during which I stopped on my way to Muir Woods to photograph the San Francisco skyline from above the Golden Gate Bridge. I was initially concerned that the morning would be too clear, since I am usually more interested in scenes with varied atmosphere. When I arrived it was mostly clear, though there was a bit of low fog out over the bay and some low clouds clustered above San Francisco, especially the downtown area where the tops of buildings were in the clouds.

I made a series of photographs of the skyline using my longest lens – others may appear here before long. This was one of the last ones I was able to make as the clouds thickened and eventually blocked my view completely. (What had started as a largely bright and clear early morning eventually evolved into a very foggy scene.)

Fern and Redwood Log

I’m always a sucker for the interesting forms of the ferns in the redwood forest, here at Muir Woods National Monument and elsewhere. This curving example was lying across the surface of an old, dead fallen redwood trunk, and was accompanied by some brown ferns, a few odd redwood needles, and what I think may be a brown bay leaf.

Although this was shot near the very end of fall, the atmosphere at Muir Woods was very much that of winter. There was just a bit of thin fog floating around here and there, and on the forest floor beneath the giant trees it was very damp and quiet and dark. (If you want evidence of the low light… note that this was a 15 second exposure!)

Mushrooms, Redwood Log

December 18, 2010 G Dan Mitchell 4 Comments

Winter mushrooms grow on a redwood log at Muir Woods National Monument.

Yesterday I decided to squeeze in a quick shoot in the Muir Woods area on a relatively nice day before what promises to be a week of substantial rain. So I was on the road early, stopping at the north end of the Golden Gate Bridge to photograph the San Francisco Bay at sunrise before continuing on to Muir Woods. I arrived pretty early – I know I’m there early when I get the very first parking space closest to the entrance!

This is a beautiful time of year in the redwood forest, but there seems to be a smaller number of visitors. I suppose the wetness may keep them away – there is mud and water everywhere – and not everyone is willing to deal with the cold. The main grove at Muir Woods sits in the bottom of a canyon that doesn’t get a whole lot of sun this time of year, especially very early and late in the day. Combine wet with cold and low light… and you can understand why it was a fairly quiet morning there, with only a few other people wandering about.

I know that winter is the mushroom season in places like this, but I was very surprised by the number of mushrooms growing there yesterday and my the astonishing variety of types. There were the large curving brown ones (sorry, I’m not a mushroom ID expert, to say the least!) clustered in the upper area of this shot, the brightly colored yellow ones, tiny white ones, and many other shapes and colors and textures. I wish that I could have stayed longer to photograph more of them, but I think I’ll try to return after the current cycle of storms ends.

I’ll add a couple of photographic observations here, too. First, this is another shot that demonstrates, I think, the usefulness of the 70-200mm zoom lens. Working here at close to minimum focus distance, the longer focal length gave me a bit of working room and still provided a nice background blur. Second, the redwood forest is a very dark place! I don’t know how you could shoot these subjects handheld – this shot used a 6 second exposure!

Regarding Sharpness. And Obsession.

December 17, 2010 G Dan Mitchell 3 Comments

We have all seen the lengthy discussions about “which lens is sharpest.” While the ability of a lens to resolve detail is certainly important, it is not the only thing that is important. And in many cases, knowing which is the sharpest lens is not as important as know which among a number of sharp alternatives best suits your needs. I stumbled into another discussion of this topic online today and posted the following as my contribution. (Slightly edited here from the original post.)

Folks sometimes allow themselves to become completely distracted by “sharpness” to the point that they overlook a whole bunch of other important issues in their quest to find the holy grail of “sharp.” This can become the equivalent to realizing that good tires are important on a car, and then deciding to buy a particular car because it comes with the “best” tires… but is too big to fit in your garage, costs twice your annual income, has a terrible repair record, needs a tune-up every 750 miles, and only comes in a color your spouse hates.

For a few people doing certain types of very critical work, printing very large, working slowly and methodically, and willing to forego the compensatory advantages of other lens options, lenses like the excellent TS models, lenses from another manufacturer that only work with adapters, classic primes, and so forth might make some sense.

But just because a lens might measure a bit better to some extent in one of the areas that is measurable (e. g. “sharpness”), it does not necessarily follow that it is a better lens, nor that alternatives that may measure differently in sharpness – but are very nearly as good – will not also be excellent performers. It is also not true that these specialized lenses are required to produce large and effective prints.

It is interesting to watch people go through a process that may look something like the following at times, as they…

1. decide they need a sharper kens.
2. research lens sharpness.
3. consider only sharpness and overlook or dismiss other issues, including those mentioned in the sources analyzing sharpness.
4. decide that some lens is the “sharpest” – frequently some expensive prime, the most expensive zoom they can find, an alternative brand, a specialized TS, etc.
4.5. lust after said lens for some period. The excitement builds…
5. purchase the aforementioned Really Really Sharp Lens.
6. use the new lens and glory in it’s pure Divinely Sharp Wonderfulness, thereby confirming their wise choice.
7. share their wonder with others.
8. make more photographs, and eventually come to find out that a) in real photography the sharpness difference is rarely visible, b) there are downsides to using the sharper lens, c) the downsides sometimes compromise or lose the shot, and d) in many cases their previous “less sharp” lens proves just as useful and effective.
9. note that the new super Super Lens, while useful, begins to spend more time in the bag, and…
10. learn an important lesson or two about Lens Lust… or else repeat the cycle with a different WonderLens. :-)

To be clear, I’m not suggesting that sharpness is unimportant. I’m just encouraging people to keep things in perspective.
