The more you understand these meters and how they work, the better you will be at understanding and interpreting what they are telling you. Keep in mind that incident light meters are far more accurate than reflected light meters. Reflected light meters attempt to read the amount of light in the scene you are trying to capture. Unfortunately, those readings are guesses.
You may have had the misfortune of photographing a very dark or black subject and have it come out looking over exposed, or a snow scene where the snow looks grey or under exposed. This middle grey is a mid-point between the darkest shadows and the brightest highlight. Since the camera meter has no idea about white or black, you need to help it using some form of exposure compensation based on the tonality of your subject or scene. To help with exposure, and determining how much to compensate, cameras have various metering modes.
Typically, the three basic modes are Matrix also called Evaluative , Center-weighted and Spot metering. Each of these is applicable in particular situations, but do not rely on just one of these modes to do it all for you.
In this metering mode, the meter divides the scene up into a grid and analyzes each segment for highlight and shadow bright and dark information.
Once that data is collected, it calculates the average value and bases the exposure on that average. Keep in mind that all cameras do not have the same number of areas within the frame. Manufacturers use complex formulas to arrive at exposure values. Therefore, it is important that you understand how your camera behaves in various situations and learn when to trust it, and when not to trust it.
In the next series of images, matrix metering was used to set the exposure. Two foam-core boards, one white and the other black, were placed side by side in the same light. For the first image, the camera read the exposure while it was pointed in the middle of the white and black boards. The camera read all the white and the black and came to a reasonable conclusion by averaging the exposure. Meter with a reflective meter and set to zone V.
We have 'average' Caucasian skin ie, not pasty but not super tanned and it used to work just right for us. I don't think I really thought about that technique again after i bought an incident meter though. Apr 8, 8.
We all seemed to be agreed that the key for the "palm reading" is a reflectance meter so it is intriguing that the OP mentions an incident meter. Hopefully the OP will clarify his source in terms of what book it is pentaxuser. Apr 8, 9. Messages: 7, Apr 9, Messages: 9, Weston meters have a position marked C for metering off the palm.
It's just normal metering plus one stop of exposure. Caucasian or not doesn't matter. Regardless of skin colour, the palms are universally about the same shade. You must log in or sign up to reply here. Show Ignored Content. Your name or email address: Do you already have an account?
This means that if you meter off your palm your shots will be underexposed by a stop. Perfect exposures every time. The back of the hand is an alternate technique that works in the same way. But the skin on the backs of our hands changes more frequently. So, we have to calibrate more often to a grey card to see how far out we are. Once you know how far out their hand is from middle grey, you can get it every time. Of course, this means taking a grey card out with you on every shoot.
No need to keep pulling out the grey card or have them bring up their hand. But, they can be a handy backup when you find yourself with no other options. Some of them are even more expensive than the camera. In fact, every one of us already owns a very handy tool for photography — your hands! Controlling the light source is one important key to photography.
Before we press the shutter, we need to test the direction of light. Apart from identifying the light source with your bare eyes, you can use your hands to test. See below for method:. Hold a fist with the protruding joint connecting your thumb and index finger to your palm facing yourselves the lens. Then imagine this is the nose, and the fist is a head.
Top light.
