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

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

Dry Creek and Late-Season Meadow

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.

Three Aspen Trunks, Lichen Covered Rocks

Three Aspen Trunks, Lichen Covered Rocks

Three small aspen trees with fall color leaves among small plants grow from a crack in lichen-covered rocks – Sierra Nevada, California near South Lake.

Yet another variation on the “bare aspen trunks with some leaves, photographed against granite” theme – I can’t help myself! :-)

This is another of several photographs I made along the road below Parcher’s Resort on the way to South Lake in the eastern Sierra above Bishop, California. At this early October point in the season there are almost endless ways to approach photography of aspens – still-green aspens, aspens barely starting to change color, newly colorful aspens among still-green aspens, aspens at the height of their yellow/orange/red color, aspens past peak starting to thin a bit, aspens with only a few beautiful leaves remaining (and the rest littering the ground beneath), aspen trunks bare of any leaves and waiting for the winter to arrive – and all of these shot in an infinite variety of light, in an infinite variety of settings, with an infinite variety of compositions.

So I hope no one minds if I continue to post a few more. :-)
