Tree and Rocks, Lower Young Lake

September 24, 2010 G Dan Mitchell Leave a comment

A small tree growing on rocks near the shoreline of Lower Young Lake, Yosemite National Park, California.

I first saw this small tree growing in the cracks of rocks near the shore of the lake the morning before I made this photograph. At that time the tree looked interesting but the light was not so great. So visiting this tree again was on my agenda for the following morning and I got there a bit earlier. I made a number of exposures of this scene, and I’m still not certain which one(s) I think work the best – so there is a chance that one or more additional photographs of this subject may appear before too long.

Young Trees and Pond, Dana Meadows

August 14, 2010 G Dan Mitchell 2 Comments

Young lodgpole pines grow in front of a Dana Meadows pond as Mammoth Peak looms in the distance.

Late in July of this somewhat wet year, the portion of Dana Meadows that extends almost up to the top of Tioga Pass was still very green and a bit wet, with small streams flowing through it and seasonal tarns still full. Being careful to avoid the boggy spots, I wandered down in to this section of the meadow near where the old roadbed is still visible and found small ponds and young trees trying to infiltrate the meadow. Here the pond reflects clouds floating towards Mammoth Peak, the high point at the end of Kuna Crest, on the other side of which is found the Lyell fork of the Tuolumne River.

Experiment #2: A Hint

December 15, 2009 G Dan Mitchell 2 Comments

Here are the three source images:

The differences among them are obviously in the amount of noise that was added to the image. No noise was added to the first image – any noise there was in the original capture. 10% level “Uniform” noise was added to the second image in Photoshop. 20% “Uniform” noise was added to the third image in the same way.

The soft photograph was chosen to avoid masking the noise with a lot of other sharp detail – this image provides very smooth gradients from black to white, where noise is typically easier to detect. I also chose this image because it is nearly – but not quite – monochromatic. This meant that I could increase the effect of the noise by using color noise rather than limiting to monochromatic noise – and that the color noise would tend to be more visible against the nearly monochromatic background.

The original set of 6 jpgs includes two from each of the three versions shown here. For last-minute fun you could still visit the comment page and try to a) determine whether or not the differences are visible and b) which pairs of images are the least noisy, more noisy, and most noisy.

More information to come later this evening.

Dry Creek and Late-Season Meadow

December 11, 2009 G Dan Mitchell Leave a comment

Morning light illuminates a dry creek bed winding though late season meadow grasses and trees near Fletcher Lake, Yosemite National Park, California.

As the trail at Fletcher Lake heads upward to begin the climb towards Evelyn Lake there is an area in the meadow to the left of the trail where small trees have begun to infiltrate the meadow and there is now a “mini-forest” of sorts. I’ve photographed this spot – this exact spot, actually! – before, and I often like to shoot it in the morning light when the low angle sun first hits the meadow. Here a dry seasonal runoff creek winds between the trees in this section of mixed meadow and young forest.
