My Basic Camera Settings and Imaging Strategy

Photography is a constant compromise in choosing settings to record an image. Note, there are no absolutes. Here I describe what works well for my photography. What works well in one situation may not in another. If you find the settings below too complicated, see the Caveats, Caveats, Caveats section at the end. But once you are ready to push your photography to higher levels, try these settings and methods.

Below when I describe autofocus, I am referring to DSLRs. If you are using a point and shoot camera with contrast detect AF, speed is severely compromised, so photographing moving subjects is a challenge. But other strategies still apply to point and shoot cameras.

Here is how I set up my DSLR camera:

I use the above methods for most photography, including people, pets, and even landscape. But with static subjects like landscapes on a tripod, then I change from servo mode to one shot focus lock mode.

A vulture comes in to a kill on the northern Serengeti. Photographed with a 300 mm lens with 1.4x teleconverter, AI servo tracking, manual exposure. The light was the constant warm light of early morning, with no shadows on the subject, thus a constant exposure was used, determined earlier to not saturate the white patches on the bird. Yes, light from the rising sun is not constant, but it is close to constant over several minutes once the sun clears the horizon and especially so in a clear sky. One needs to check exposure only every five to ten minutes. Image made at 420 mm, f/5.6, 1/1600 second, ISO 200, hand held.

A lion heads back to his pride after a fierce battle in the southern Serengeti. Photographed with a 300 mm lens with 1.4x teleconverter, AI servo tracking, exposure by aperture priority (I chose the f/ratio, camera chose exposure time). The lion was moving through a forest just after sunrise at a speed of 1.7 meters per second (3.8 miles per hour), with the light from the left. Thus he was moving into shade and sun. With the rapidly changing light, manual exposure could not be done, so I chose aperture priority. But the strong light on the side of hi legs and face meant I needed to include some exposure compensation in order to not overexpose the brightest parts. The light was changing every few seconds on the lion. Image made at 420 mm, f/5.6, 1/250 second, ISO 800 using a beanbag. I placed a single AF sensor on the open eye, near the rule of thirds point.

A beautiful white bird, a great egret, swoops over a lake in backlit sunlight, with the background is deep dark shadow. Most automated camera metering would fail in such a situation and severely overexpose the bird. Most spot meters in cameras do not have a spot small enough, and it would be difficult to keep that spot on the brightest part of the bird. So I used manual exposure. I planed for this image and set my focus point to above center so I could also get the reflection. I set the exposure on white birds nearby that were in full sun. Made with a 300 mm lens at f/4.5, 1/3200 second exposure, ISO 200, hand held.

Serengeti sunrise. This image was made using manual exposure to control the bright sunlight and well as very red sky. I took test exposures and displayed the 3-color RGB histogram (I only look at the histograms for each color channel, not the default luminance histogram). I chose an exposure that did not saturate the red but slightly overexposed parts of the disk of the sun. Image made in AI-servo mode, 300 mm lens at f/8, ISO 100, single AF (central) point on the tree branches, using a beanbag from a safari vehicle.

A child running in low indoor light. The camera was in vertical (portrait) orientation and one focus point was on the eye. Exposure used aperture priority, wide open at f/4, 105 mm focal length, 1/50 second at ISO 1600. One focus point with AI servo tracking, hand held. The lower shutter speed shows motion, but in the key components, like the legs and arms, but the eyes and face are sharp. This image was a harder situation than with the lion image above, including 10 times less light and faster random movements! It was also harder to get than the bird image above due to fast random movements of the child.

Additional Info

This page describes the servo mode more and how one tracks a subject with a camera: Tracking Action With Autofocus.

Finally, watch the backgrounds. While one may have blurred the background pretty well, but out-of-focus sticks coming out of a person or bird's head usually ruins an image. Try moving slightly left or right to avoid this or used a wider aperture.

Be aware on the common problem of images that show the softness typical of zoom telephotos. For those considering telephotos, you will get better image quality with a fixed focal length lens, even with teleconverters. Fixed focal length lenses usually have much faster autofocus than zooms, especially consumer zooms.

For example, Figure 10 on this page: shows the difference between a Canon 100-400 L IS lens at 400 mm versus a Canon 300 mm f/4 L IS with a 1.4x TC. The 300mm is clearly sharper and would be against all other telephoto zooms (except the Canon and Nikon 200-400 telephotos which run many thousands of dollars). The difference would be larger compared to a consumer zoom telephoto.

A 300 f/4 +TC (both Canon and Nikon have these, not sure about Sony, Pentax) will produce sharper images than zoom lenses and is a great starter lens for wildlife photography.

For those of you with zoom telephotos, next time there is a moon out that is similar in phase to the images on the above (moon-test2) web page, image the moon when very high in the sky and see how your lenses + technique compare.

Also a note on filters on such big lenses: most filters will probably degrade image quality. See:

Caveats, Caveats, Caveats

If the above is too complex for you at this stage of your learning, no problem. In my opinion, it is more important to learn lighting, composition and the subject than it is to fret over ISO, f/ratio and exposure times. So I recommend simply using the auto modes on your camera. For example, portrait mode for making people and pet portraits, landscape mode for general scenery, and sports mode for action, including things like baby's first steps. You'll likely find that the exposure modes do very well most of the time. But as you push to new limits, from faster action to unusual lighting like back light, one can make better images by taking control of the camera and using settings like I describe above.
