I recently posted the black and white version of this photograph of Cascade Creek in full spring flow. I am still undecided about which I prefer. I haven’t printed either as of the date of this posting, and the results of that further work may help me decide.

The color version of this photograph posed a series of post-processing questions and problems that others who have worked with a scene like this one can probably imagine. The creek descends through a narrow, rocky gorge at this point and I photographed it early in the morning before any direct sunlight was able to reach the water. Benefits of shooting at this time included the softer light, which tends to both throw some light into the shadows and to soften the brightest highlights. This also permits a longer exposure which allows the water to blur a bit and express the wild motion of the creek. However, since the primary source of light was the open sky, the camera “sees” a very blue scene. (Our visual system compensates for this, so it doesn’t look as blue as it really is when you are on the scene.)

There are several ways to deal with the color balance issues that this situation creates. You could just “go with the blue,” and I’ve seen photographs done that way. I’ve even seen some in which the photograph amped up the saturation and ended up with something very blue. In general, that’s not my thing! I’m most often looking for something that seems “believable” – it may not be objectively accurate, but I intend it to be “subjectively accurate.” With this in mind, my first instinct was simply to warm the color balance in order to move away from the blue cast and toward a warmer one.

My immediate impression was that this was an improvement, and I worked with this interpretation for several days – but something about it didn’t sit quite right with me. (This is perhaps one reason that I also worked with the black and white rendition in the meantime.) Eventually I did some comparisons between the “warmed up” version and the original… and neither seemed like what I was after. The overly blue original looked garish but the overly warm version seemed artificial. I tried some other approaches and finally discovered that because the blue was so intense that I could simply desaturate it – more than you might think – and keep the “colder” coloration without letting it overwhelm the image.

Runoff from spring snow melt rushes over boulders of Cascade Creek, Yosemite National Park.

This is a subject that I return to several times each year – a particular section of creek that can be viewed from overhead and which can vary from nearly dry to a wild torrent depending upon the time of year and the character of each new year. During the past year I was inspired by Charles Cramer’s stunning photograph of this subject to look at it more closely and from some different perspectives. (A small bit of “Charlie’s scene” appears in this photograph. I wonder if you can find it? :-)

In some ways, the view of this scene is limited in that you can only see it from a particular range of positions – unless you have the skill of levitation! In another way it is hardly limiting at all since the larger view contains many possible smaller views of rocks and plants and water and light. I still have in mind a horizontal composition in this general area, but so far it hasn’t quite worked. Guess I’ll have to keep trying.

I made this photograph in the morning before any direct light had worked its way around the mountains and down into the stream bed. Beyond the stream, which drops precipitously into the Merced River far below, there was open sky and that is the light that reflects on some of the wet rocks. By playing around to find an appropriate combination of ISO values, aperture, and shutter speed, I tried to get the water to hold some detail but to also be blurred enough to reflect its wild motion as it tumbles down this rocky canyon.

As is sometimes the case, I still cannot decide for sure between this monochrome version and a color version that will appear here before long.

Oak, Laurel, and Granite

Oak, Laurel, and Granite. Yosemite Valley, California. May 7, 2011. © Copyright G Dan Mitchell – all rights reserved.

An oak tree and a laurel tree grow next to a granite face along the north side of Yosemite Valley, California.

I have visited this small, gnarled oak tree before. It grows right at the base of a granite face along the north side of Yosemite Valley, seems to face a pretty rugged life living beneath the shadow of the cliff and among fallen boulders. When I visited in early May the tree was just starting to get its new growth of leaves, though the laurel tree right next to it was already quite green.

The last time I photographed this tree it was autumn, and the leaves were also colorful then. It seems a bit odd that the leaves of this oak take on similar yellow and red colors at both the start and end of their season. (Though they do go more toward brown than yellow in the fall.)

The light was interesting on this day, which had started out clear. As the day wore on a weak Pacific weather front approached, and by evening things were pretty well socked in. But here, at perhaps 4:00 or 4:30, if I recall correctly, the incoming clouds were thing and broken enough to just soften the light without turning it completely gray.

Two Oaks, Morning Sun

Two Oaks, Morning Sun

Two Oaks, Morning Sun. Calero Hills, California. April 30, 2011. © Copyright G Dan Mitchell – all rights reserved.

The springtime morning sun shines through a pair of oak trees in the Calero Hills south of San Jose, California.

On the final day of April and for the first time this season, I found to go for a hike at my favorite local park, a place where I have walked just about every available trail (and invented a few routes of my own) and photographed for a number of years. The park would not seem like anything all that special by comparison to some of the other places I visit, but it is close and I’ve gotten to know it in a way that makes it more special. The place is called the Calero County Park, part of the Santa Clara County Parks system.

The entrance to the park is in a broad valley that is largely occupied by stables. (Or, used to be – it looks like the stables must have closed since last season.) Rising from this valley are the typical grass-covered hills of central and northern California, with oaks and other trees scattered around and, in places, thicker trees and brush. At this time of year, the hills turn what I call “impossibly green” – and if you have seen them on a late-winter or early spring morning you know what I mean.

I started this hike a bit after dawn, so the golden hour light was more or less gone. I had a general idea of photographing some wildflowers (which didn’t happen – it was too windy) and some oak trees that grow alone or in small groups on the grass-covered hills. I passed a small lake – where a single egret often hangs out, but not on this morning – and topped a rise and descended into a small valley from which I have made quite a few photographs of oaks. It didn’t look too promising at first, but at the far end of this area I noticed that a pair of trees were still obscuring the sun and that I might be able to shoot straight into the sun with the trees blocking its disk, and get a photograph including the tree shadows on the hillside grasses.

This turned out to be another of those all-too-common ephemeral photographs in that the sun was starting to rise above the top branches of the tree and would soon be “out in the open,” making it much too bright for what I had in mind. So I worked quickly to set up tripod and camera and select a lens, then frame a composition, focus, and make a series of exposures that might be needed to deal with the huge dynamic range between direct sun and backlit tree trunks. By the time I had everything set up and was ready to shoot the sun had already risen above the upper branches, so I ended up looking for a slightly better shadow and putting the tripod down very low – and this gave me must enough time to make the series of exposures I figured I would need.

In the end, I got lucky. One single shot somehow managed to not blow the sun out too badly yet hold enough detail in the grass that a bit of work in post could bring it back. With all of the potential for lens flare – which I had to some extent in every shot – this one only had two small bits of it, and they were easily dealt with.
