10 Rules – A good starting point

Looking DownPhotography is often all about breaking rules – rules of composition, lighting, and so forth. So what better way to set you up for breaking of said rules then to give you 10 Rules of Photography to Live By”. And honestly – these are more guidelines then rules – and they work pretty darn well – so break only if you really, really need to!

10 Rules to Live By

1. Sunny 16 Rule
The basic exposure for an average scene taken on a bright, sunny day is f/16 at a shutter speed equivalent to one over the ISO setting—that is, f/16 at 1/100 sec at ISO 100. From this you can interpolate, and try f/22 at the beach, f/11 on a cloudy-bright day, etc.

2. Moony 11, 8, and 5.6 Rules
There are many different rules that work well when shooting the moon. One favorite for a proper exposure of a full moon is f/11 at one over the ISO setting. For pictures of a half moon, use the same shutter speed at f/8, and for a quarter moon, use the same shutter speed at f/5.6.

3. Camera Shake Rule
The slowest shutter speed at which you can safely handhold a camera is one over the focal length of the lens in use. As shutter speeds get slower, camera shake is likely to result in an increasing loss of sharpness. So, if you’re using a 50mm lens, shoot at 1/60 sec or faster. Not enough light? Use a flash, tripod, or brace your camera against a solid object.

4. Anatomical Gray Card
Metering off an 18-percent neutral gray card is a good way to get a midtone reading that will give you a good overall exposure of a scene. Forgot your gray card? Hold your open hand up so it’s facing the light, take a reading off your palm, open up one stop, and shoot. (Various skin tones rarely account for even a full-stop difference.)

5. Depth of Field Rules
When focusing on a deep subject, focus on a point about a third of the way into the picture to maximize depth of field, because the depth-of-field zone behind that point is about twice as deep as the depth-of-field zone in front of it. This works for all apertures and focal lengths, but the smaller the aperture and the shorter the focal length, and the greater the distance you shoot at, the greater the depth of field.

6. Exposure Rules
The classic advice is, “Expose for the highlights, and let the shadows take care of themselves.” This works with slide film and digital. But with negative film, especially color negative, you’re better off overexposing by one stop.

7. Quick Flash-fill Rule
When using an automatic flash unit that doesn’t provide auto flash-fill ratios, set the flash’s ISO dial to twice the ISO you’re using. Meter the scene, select an f-stop, set the autoflash aperture to the same f-stop, and shoot. The resulting 2:1 flash-fill ratio will produce filled shadows one stop darker than the main subject.

8. Flash Range Rule
Want to know how much extra flash range you get by going to a faster ISO? The rule is, “Double the distance, four times the speed.” For example: If your flash is good to 20 feet at ISO 100 (film or digital), it will be good to 40 feet at ISO 400.

9. Action-stopping Rules
To stop action moving across the frame that’s perpendicular to the lens axis, you need shutter speeds two stops faster than action moving toward or away from you. For action moving at a 45-degree angle to the lens axis, you can use a shutter speed one stop slower. For example: If a person running toward you at moderate speed can be stopped at 1/125 sec, you’ll need a shutter speed of 1/500 sec to stop the subject moving across the frame, and a shutter speed of 1/250 sec to stop him if moving obliquely with respect to the camera.

10. Sunset Rule
To get a properly exposed sunset, meter the area directly above the sun (without including the sun). If you want the scene to look like it’s a half-hour later, stop down by one f-stop, or set exposure compensation to minus one.

Man – don’t you love lists?!?!?


  1. This is a great list…thanks. And yes, I do LOVE lists. Does Debra read this site? She’ll drool over the list!

    And, I love you for the post above 🙂
