Their response in low light and high light conditions may not match response at the mid-range of light. But the worst characteristic, for practical purposes, is that all reflected light meters make one basic erroneous assumption.

They are calibrated to render an exposure that will make the subject look like a middle tone in the resulting photograph. How do you compensate for the fact that your meter is lying? You have to lie to your meter. If you are photographing a light toned subject, such as snow or sand in bright light, you must convince your meter that it is looking at something even lighter than your subject, so that the meter's attempt to make it a middle tone will result in the right tone.

The same is true for dark objects.

### Ultimate Exposure Computer

You must tell your meter that the object is darker than it really is so that the meter's compensation will register the correct tone in the photograph. You can tell this white or black lie to your meter in a couple of ways.

You can meter a middle-toned area in the same light as your subject and manually set your camera accordingly. You can lie to the camera outright by telling it that it is using film of an ISO rating different from what is actually in the camera.

For instance, if you are using ISO film and are photographing a light subject, you would tell the meter that you have ISO 50 film. If you are photographing a dark object, tell your meter that you have ISO film in the camera. This method works well for cameras in automatic exposure modes. Be careful to tell your camera the truth if you move to a middle toned subject. Another way to get the right exposure from a lying meter is to politely ignore it.

Switch from automatic to manual exposure a good idea anyway and simply move to the next larger aperture or the next slower shutter speed for a light object or to the next smaller aperture or faster shutter speed for a dark object.

Your meter deceives you, so you deceive it. But what kind of relationship is this? The Ultimate Exposure Computer does not make erroneous assumptions, because you tell it what type of light your subject is in. As long as you tell it the truth, it will not lie to you. Definitely a better relationship. There is a chance that the preceding section may have confused you. If that is true, don't worry about it. After you've read the next section, revisit this section again, because the concept is important.

Each of these four factors is represented by a series of numbers. Your camera may have only a portion of each series indicated. In most light meters, photons of light that are reflected from your subject put pressure on a photo-sensitive receptor in your light meter and are converted into electricity this is why some meters do not require batteries.

The greater the number of photons, the greater the electricity that is produced. Internationally accepted standards specify exactly how much light pressure equals a certain EV number. This value is measured by the following number series for ISO film: However, even though this appears to be a linear progression, each number represents twice as much light as the numbers increase. This provides an easily memorized scale to clarify the concept of "absolute value of the amount of light falling on a subject".

This term is related to illuminance, footcandles and lumens. But it doesn't matter. If you are using a light meter this number is irrelevant, and you can ignore it. You may never see these numbers, because the meter uses them internally to calculate a set of combinations of shutter speeds and apertures. However, knowledge of Exposure Value can significantly enhance your ability as a photographer. The Ultimate Exposure Computer gives you the knowledge to take control of your photographs.

The relationship between these four elements is represented in the Ultimate Exposure Computer. Film speed is a number that indicates the sensitivity of film to light. In general, films with a higher sensitivity larger number have coarser grain and do not register detail as well as films with lower sensitivity lower number. The number series for film speed is: Moving to the right, each number is twice the preceding number, and represents twice the sensitivity to light as the preceding number.

There may be some intermediate steps such as 64 or on your dial. Set the light meter or camera for the same number that is on the film. Your camera may do this automatically. This leaves only two things to adjust to achieve the correct exposure while making a photograph; shutter speed and aperture f-stops. Shutter speed and aperture are very important to the creative photographic process. Shutter speed indicates how long the camera shutter remains open to let light onto the film.

The number series for shutter speed is: These numbers are whole seconds or fractions of seconds. They aren't expressed on your shutter speed dial as fractions to save space, so they should read as below: There is an important rule regarding shutter speeds: If your shutter speed is slower than the reciprocal of the focal length of your lens, you must use a tripod.

If not, you should use a tripod. If your subject is moving, double this shutter speed. If you are moving such as in a boat or plane triple the speed. If you are doing macro work. If you're using a format larger than 35mm, use a tripod. To be safe, weld your camera to the tripod. If you are a serious nature photographer you will always use a tripod, anyway. A tripod will allow you to make photographs with slower film speeds.

Slower film speeds equate to better detail and sharpness in your photographs. More important, using a tripod makes you slow down and allows you to examine your composition more carefully. Modern electronic cameras may lack certain features of the older, mechanical cameras such as a button that allows you to see the depth of field that will be present in your photographbut every camera has a tripod socket. You'll make better photographs if you use it. Aperture refers to the size of the opening inside the lens that the light must go through to reach the film.

These are actually fractions. They should read as follows: But why do the numbers look so odd? I recommend that you ignore it, because it doesn't matter anyway. Just accept that each progression represents half as much light as the preceding number. If you are curious as to how we got to such a seemingly illogical progression of numbers, read the following three paragraphs.

## Pregnancy Confidential Podcast Week 11: Pregnancy is The Ultimate Relationship Test?

If you aren't curious, you can safely skip them. The numbers represent the ratio of the focal length of the lens to the diameter of the lens diaphragm opening.

As you no doubt learned in high school, the method of calculating the surface area of a circle is Pi times the radius, squared Pi is approximately 3. Therefore, in our example, the surface area of the opening would be 3. The surface area would be 3. If you multiply it out, you will see that the surface area is now approximately sq.

The reason we use the ratios instead of the actual surface area of the diaphragm opening is that the actual surface area would be quite different between lenses of different focal lengths. Photographers would have to memorize a series of numbers for each focal length lens they owned. Think about what you'd have to do with a zoom lens! Ratios allow us to use the same number series for all of our lenses.

The good news is that you only have to remember two numbers; 1 and 1. Double each one alternately and you will have two series: Some cameras may include numbers between the numbers mentioned above.

ARE YOU AND YOUR CRUSH MEANT FOR EACH OTHER? Love Personality Test

Those numbers represent half or third stops. For the purpose of what you are learning here, ignore the in-between numbers. But you could if you wanted to. The purpose of this section is to show you how Exposure Value, Film Speed, Aperture and Shutter Speed are interrelated, and why you don't need a light meter to know the proper exposure.

These cameras work well for family pictures and many urban subjects. Automatic focus and exposure especially TTL flash are extremely useful for some specialized types of photography, such as sports or photojournalism. Nature photography is a different matter. Many of your subjects will not have "average" tonality. Most of your subjects will not be located in "average" light. Many times your subject will not be in the center of the frame where an automatic camera takes its light readings.

However, the most important reasons for putting your camera on manual while photographing natural subjects are: Other times you may want to exaggerate the effect of motion, such as when photographing flowing water. This is controlled by the shutter speed. Sometimes you will want the flower to be in focus while keeping a busy background softly out of focus.

You must make these aesthetic choices. The camera has no way of knowing what you want the photograph to look like.

Remember that the camera's automation is designed to make technical decisions based on average subjects in average light. It is not designed to make aesthetic choices regarding natural subjects which are rarely "average".

Because of these factors, the same camera that will give you dozens of perfect photographs of your children opening birthday presents will churn out dozens of badly exposed nature photographs that look nothing like what you experienced in the field. The only way for you to get good results in nature photography is for YOU to make the choices.

Purchase two sets of batteries and install one set in the camera. Do this even if you changed batteries last month. Keep the spare set with the camera, always. Keep a copy of the Ultimate Exposure Computer with the camera and the batteries. Find your instruction manual.

Now comes the hardest part of the entire process unless you've lost the manual. You must find out how to set your camera body to its "manual" setting. I can't help you here. Good luck and congratulations!

You've just taken the first step toward becoming a serious nature photographer! Take a look at Exposure Value Chart A. The left column of the chart contains the Exposure Value EV numbers. The right column of the chart contains some lighting situations that equate to EV numbers.

### Proportional relationship calculator

The chart ranges from EV -6 to EV This represents a range of light from below reflected starlight to the brightest light in the Solar System. Notice that most daylit subjects fall within a narrow range from EV 11 to EV It is a good idea to memorize the characteristics of these daylight Exposure Value factors. Pick the film speed you use most often.

Starting with that film speed, move down the column until you reach the EV number that you chose from Chart A. Now move to the right along the row until you cross the double line.
