Most wildlife are medium to dark in tone, making them a challenge to meter properly in the bright, white tones of winter. If you trust your camera’s auto exposure modes, the odds are good you won’t get the best exposure. If you switch over to manual exposure and make the right decisions, you can get great exposures and better quality photos (more about that later).
This is the fourth in an ongoing series of articles on winter photography (links below).
It would be especially helpful if you read Metering Snowy Daytime Winter Scenes if you haven’t already. The principles in that article apply to this one.
This cougar is an example of one of those rare situations when the animal is so close you can actually meter the side of the animal with no risk of the camera being fooled by the background.
This photo was taken using slide film, which in some ways is different from metering with a digital camera camera. With both slide film or a digital camera, you do not want to blow out any of the highlights or they are gone forever, never to be reclaimed. However, slightly underexposing slide film can increase the saturation of the colors. Underexposing a digital file damages the quality of the colors. To capture the rich colors of the cougar, I zoomed in a metered the side of the cougar, subtracted about 1.2 stop of light from what the meter said (-1/2 stop exposure compensation), zoomed back out to recompose and took the picture. When I got my processed slides back the colors were exactly what I wanted. Of course the intense expression on the cougar’s face was exactly what I wanted too.
If I was taking the same photo with a digital camera, I would meter the side of the cougar and use that as exposure, no exposure compensation necessary. If you are not using exposure compensation on a regular basis, read the articles in this series and the links at the bottom of this page.
Exposure compensation is the key to getting the right exposure, and it is also the key to getting the best colors your camera is capable of producing. One of the secrets of great color is to get the best possible exposure. If you miss the ideal exposure by more than 1/2 stop, the color in your photo with shift in different directions. You can’t correct for this after the fact with image editing software. Since the colors shift in different directions, if you correct one color, the other colors in your photo become worse. There is no getting around it, if you want great color, you have to master exposure. Getting great exposure is why some photographers consistently get great colors and for everyone else it is hit or miss.
The exposure for this bobcat is tricky, thanks to the high contrast scene. Auto exposure is pretty much guaranteed to blow the exposure for this bobcat. There are too many dark tones in this photo. With the camera meter’s passion for middle gray tones, it will lighten the dark tones and seriously overexpose the sunlight on the bobcat’s face. Spot metering the bobcat’s face is one way to get the right exposure, but most camera’s don’t have a small enough “spot” to do this accurately. This is when substitute metering comes to the rescue.
The same light of the rising sun (to the left) that was side lighting the bobcat was also hitting me. That makes the solution simple. Take out an 18% gray card, turn it so the gray card is directly facing the sun, meter the gray card and lock in that exposure setting, preferably in manual metering mode so the setting doesn’t change, put away the gray card away and take the picture of the bobcat.
When I took the photo of the bobcat I was facing south and the sun was coming up in the east. The angle of the gray card is critical. If you follow the typical advice to have the gray card facing the camera to the north rather than the light source to the east, you will totally miss the right exposure. Have the gray surface of the card facing the sun, which means you will have to turn and face west to meter the gray surface of the card. Once you meter the gray card and lock in that exposure, turn back to the south to take the picture of the bobcat. Learn more in How To Use an 18% Gray Card.
The simplest and most accurate way to meter this scene (and also the most expensive) is to use an incident light. Just point the white dome of the incident light meter at the sunlight, push the button, check the results (aperture and shutter speed) on the incident light meter and transfer them to your camera. The only catch is you have to own an incident light meter.
