Canon 7D Rumors

2 Comments

Speculation about a new DSLR and several new lenses is running wild on photography discussion boards this week. The current rumors, at least as of Friday evening, involve a new Canon “7D” that is supposedly a cropped sensor body with a 18MP sensor. Other features reputedly include HD video and a rather fast frame rate of 8fps. Judging from the “7D” designation it would be positioned between the 50D (or 60D?) and the 5D2 and below the current cost of the older 5D.

While I have little to offer – nothing, actually – in terms of real information about the rumors that are currently floating around about a new Canon DSLR. But, heck, if everyone else can speculate, why can’t I? Continue reading Canon 7D Rumors →

Summer Grasses, Morning

Summer Grasses, Morning

Summer Grasses, Morning. Castillero Pond, Calero Hills, California. August 14, 2009. © Copyright G Dan Mitchell – all rights reserved.

Dry summer grasses in morning light along the shore of Castillero Pond, Calero Hills, California.

Yes, another in this series of morning photographs of summer grasses and similar flora. Again, this was photographed at Castillero Pond in the Calero Hills not far from where I live in the San Francisco Bay Area. After a few recent trips to the high, alpine terrain near the Sierra Nevada crest, I thought it would be fun to photograph a more local and familiar subject. Although the grasses and cattails were not necessarily what I had on my mind when I went to this location, they quickly become my focus as I explored the shore of this small pond.

Plant ID’ed?

Leave a comment

@ljellis tweeted that the plant misidentified in my photo as “cattails” might be “Harding grass,” or halaris aquatica. Looks and sounds reasonable to me from the description I read online as to the form of the plant and where it grows.

The disappointment is that it is described as an “invasive species” – that can’t be good! But, darn, I still like the photo. If anyone else has further info on this, or a confirmation of the identify of the plant, I’d welcome hearing from you.

About plant identification…

Leave a comment

In case it isn’t already obvious, I’m a complete non-expert at this task. It seems that I have completely (or, “totally,” as my botanist sister writes… ;-) misidentified the plant in today’s photo.

When it comes to plant identification, I’ll readily admit that I’m far, far, oh so far, from being an expert. In one sense I know a lot – I can often recognize a plant or flower from many previous encounters. I often know exactly when and where it will grow and when it blooms, and I know where to find certain odd and unusual plants.

But when it comes to naming them, I’m often at a loss. Best case, I remember the common names of some that I’ve gotten to know over the years. More typically, I know the plant as “the one with the long stem, pointy leaves, and yellow flowers.” Worst case, I make a wild guess. As I did with the “cattail” photos.

If anyone can give me an accurate identification of this plant, I’ll be very grateful. Scientific names are fine, but common names are also great.
