This shot at Ipperwash Beach, Ontario, demonstrates the limitations of your camera's light meter (and also of this photographer!). Most scenes contain areas of widely varying "luminance" (a technical term roughly equivalent to "brightness"). In this shot you have the bright whitecaps and clouds, and the much darker sky, water and sand.

Your eye makes sense of it all, but the light meter only computes the average value of brightness in the scene. So for example when you shoot a snow-covered landscape - a scene dominated by brightness - your camera's "automatic" setting makes the snow look gray. The meter is programmed to set an exposure that brings the average level of light in the scene down to a predetermined level.

I was concerned about the opposite effect here - i.e. that the dominance of dark areas would cause overexposure the light areas - the clouds and whitecaps. So I set the exposure in the BEFORE image a couple of f-stops lower than the meter reading. But I went too far, because the whole image - even the light areas - is underexposed.

In the RAW file I corrected the exposure while keeping an eye on the luminance histogram showing the distribution of luminance across the full range of tones (from darkest to brightest). The histogram told me I was slightly overexposing the whitecaps - which I wasn't worried about because there wasn't a lot of detail in them to be preserved anyway. The benefit of doing this was getting a desirable amount of brightness in the rest of the AFTER image.

Brightening the image washed out the color of the man's red shirt, so I isolated the shirt and increased vibrancy in that area only.

The BEFORE image had a slight tilt downward to the left. I corrected this with a horizon adjustment. I also corrected a slight bluish color cast in the BEFORE image with a color temperature adjustment. I cropped from the bottom to reduce uninteresting foreground.

Notice how pronounced the vignetting (darkening around the edges) is in the BEFORE image. This was easily corrected with a vignetting adjustment to the RAW file.

To create the dreamy effect of the blurred, headless man, I set a shutter speed of 1/3 of a second.

"Boat Tour"

On a boat tour of Western Brook Pond in western Newfoundland two women focused on the spectacular scenery while I focused on them. The pastel colors of their windbreakers contrasted with each other and with the natural tones of the land, water and sky. The image tells a strong, simple story: two people awestruck by 600 meter (2000 foot) cliffs towering over a remote, pristine lake. This image required less work than many of the others featured in this blog. It's a good example of how even relatively modest adjustments can transform a photograph from merely "interesting" to "worthy of displaying". I wanted to separate the women from the landscape - make each part of the image stand out in its own right. I was taken by the colors and textures of the jackets so I increased vibrancy a little to bring out the color and used  fine-contrast and tone curve adjustments to  highlight the fabric's folds and shadows. I added drama to the background through t


The isolated coastal village of Trepassey, Newfoundland sits in the southeast corner of Canada's eastern-most province. The vantage point of this photograph makes for a classic Newfoundland scene: a sliver of human settlement poised between sky and sea. Ethereal, other-worldly: I wanted to capture that feeling. Because I had pointed my camera slightly upward to get more sky in the frame, I had to correct the resulting perspective distortion - notice in the "before" image how the lines of reflected light closest to the sides of the image are twisted away from the center.  I fixed the color temperature to eliminate the strong bluish cast. I corrected the vignetting - notice how the "before" image is significantly darker at all four edges. I cropped from the bottom of the image to bring the bottom border closer to edge of the reflected lights. How do you convey "ethereal"? For me the key elements were delicacy,  l ightness, and a sense of &qu


The tablelands of western Newfoundland are a rare geological formation - a piece of the earth's mantle, normally buried seven or more kilometers beneath the earth's crust, but forced to the surface here several hundred million years ago. The area lacks the usual nutrients required to sustain most plant life, and so is nearly barren. The high iron content of the rock accounts for the rusty brownish color. In the BEFORE image the sky is correctly exposed but everything else is badly underexposed. This was fixed with an exposure correction in the RAW image.  The BEOFRE image has a slightly bluish color cast which was fixed with a color temperature correction. After making those global adjustments, I worked separately on four sections of the image: the sky, the land in the upper part of the frame, the creek, and the large rock that dominates the lower right-hand corner.  The overall plan was to bring out the textures and contrast in the rocks, maintain the darker ton
