Photography Lesson Number One

Article by Arthur J Neysmith

Completing this lesson requires a camera in a position of manually setting exposure.

Be aware that some digital cameras have exposure compensation created in to prevent overexposure. If exposure is as well bright the highlights might be “blown out” and detail lost int the brightest parts with the image. By artificially “darkening” the image, the camera makers try to generate certain the exposures aren’t as well bright. This doesn’t affect all cameras but it does appear to become the situation for some. That approaches how the exposure required in lessons 2, Three and 4 may be slightly higher than suggested inside lessons. You’ll use the “expose towards right” method.

What may be the appropriate exposure? Not to create this complicated, but exposure is often a choice it is advisable to make. The exposure you pick determines how the image looks. But, we’ll begin having a straightforward understanding and work up from there.

Exposure consists of four factors:

how significantly light is in front of you -- which can be changed by adding lights or flash,
how sensitive the film is to light -- known as ISO (remember, I use the term “film” to refer to whatever medium employed for capturing the image, regardless of whether it’s the Digital Camera’s sensor or genuinely film,)
the quantity of light heading via a lens -- known as the aperture,
how extended the film is exposed -- known as the shutter speed.

For a smaller a lot more about how this works see the Camera Basics Page.

For the moment, we’ll set an average exposure on an average scene.

If you’re camera doesn’t have a produced in meter -- its extremely old. But, that’s okay. You’ll just must purchase a hand held meter. In case you have an SLR or advanced issue and shoot digital camera, spend some time from the manual to discover how to bring up the “Histogram” which graphically shows the quantity of light in an exposure.

First Lesson -- set your ISO to 100, set your camera to f16 and also the shutter to 1/125th of the second. (Some digital cameras are limited to ISO 200 -- which means you’ll want to cut your exposure by 1 stop, i.e. use 1/250th rather than 1/125th of the second) With this setting, take in your camera out during a sunny day, put the sun behind you and shoot one thing -- you’ll have a well exposed image. This can be named the “Sunny 16? rule.

To make life interesting, and your photography additional creative, you possibly can alter the setting and even now have the exact same exposure. These are equivalent exposures: Try heading to f11 at 1/250th of the second. Push it a little extra at f8 at 1/500th of the second. They’re all of the exact same exposure simply because the exact same total quantity of light is hitting the film.

Of course, you’re not often heading to shoot from the sun behind you on the sunny day. For other situations it is advisable to be in a position to discover your exposure using a meter. This can be inside your camera or hand held.

Looking at any scene, your meter will give you a suggestion as to what exposure to use. Most in the time that is pretty accurate.

Using your meter, take in a reading off of some thing with mixed tones in shade on the sunny day -- you’ll discover the exposure is two or three stops slower than the “Sunny 16.”

Second Lesson

One from the finest items to complete for additional accurate exposure is to meter the light hitting the specific subject you’re shooting. Discover a location wherever there’s a modest patch of light including a break inside a wall, light coming directly via a window, etc. Take a picture from far more than enough back you get plenty of the shadow area. You’ll almost certainly discover the patch of light is way as well bright from the picture. Walk appropriate as much as the patch of light and see what the meter suggests you use there. Then, go back to wherever you’re taking the picture from -- and from the camera in manual -- set the exposure to what was suggested.

You can also use your hand to aid determine exposure inside a variety of situations. Very first -- on the sunny day, do the f16 rule, setting the camera to f16 at 1/125 of the second. Maintain your hand within the sunlight and meter it. You’ll possibly notice the meter says you ought to alter the exposure. Note how a lot the meter says your hand is off inside f16 rule and retain that in mind. Lets say the meter stated you need to expose your hand at f22. That may be 1 stop darker than what’s definitely needed. Now walk to the shade and meter off your hand again. If it says f11, you know that’s a single stop as well dark, so set your camera to f8.

Knowing what your hand is for exposure can allow you to set exposure in most situations -- just ensure your hand is within the exact same kind of light as the subject you’re shooting.

A tiny a lot more accurate method to do exposures is to purchase an “18 per cent grey card.” Most camera stores and photo departments must have these. To use it, just put it beside the subject you’re shooting, and meter off of it. If you’re extra away than is practical to walk as much as the subject -- set the card during the exact same sort of light as the subject and once again meter off the card.

Third Lesson -- either with an 18 per cent grey card, or utilizing your hand as described above, meter a thing in dark shade and understand the exposure there.

A final note -- A meter is extremely handy to obtain your exposure, but it does have a limitation. As mentioned earlier, the meter thinks the globe is 18 per cent grey. Most with the globe is sort of like 18 per cent grey, but not all of it.

Look at what you’re shooting. If its black (or extremely dark), your meter will try to generate it grey -- and make the exposure as well light. Conversely, if you’re subject is white, the meter will try to generate it darker -- or 18 per cent grey.

There are two far more lessons on high key and low key photos which will assist you to handle much more extreme situations
