This is what happens, how reflective metering works, on your camera too. This is the reason some users meter on an 18% gray card (in the same light as on the subject).

The scene that does actually average to a middle gray is metered more accurately. See? Both the predominately dark scene and the predominately bright scene are exposed to be a gray scene. The ONLY change in each frame is that the black background was simply moved left after each picture, so that the camera TTL metering saw more white paper.

No cropping, ISO 200, all f/8, 1/200 second, TTL. This is how reflective metering works (it sees the light reflected from the colors in the scene).ĭirect flash, on cord off camera. The exposure you get depends on what the meter sees. Then the TTL metering reacts to the new scene it sees. The scene the meter sees is different, different ratios of dark and light colors. To make that be real clear, let's adjust only the background scene a little at time, all else stays the same (but still with automatic TTL metering of the flash).Īt each frame, the ONLY difference was that the black paper was shifted left a little, and then the shutter button was pressed again. Under or over exposure depends on the scene the camera sees.Īll of this page is speaking only about reflected meters, like are in cameras (two more pages to Incident meters). However, the camera's reflective light meter sees different scenes differently. The camera is aimed at the subject, and TTL automation exposes the picture.

More than 500,000 downloaders can’t be wrong. In addition to all the light metering functions, the app also has the added benefit of a Sunny 16 Calculator and even a Depth of Field Calculator. Offering both reflected light metering with spot metering and incident light metering (with the plug-in), Light Meter by WBPhoto is a state-of-the-art photography tool.

LIGHT MEETER FOR ANDROID

This app for Android systems is of equal user-friendliness as Lumu for iOS. Lumu also has the ability to measure incident light, colour temperature and flash with the addition of the Lumu Power, a nifty little external light meter that plugs into your phone. Simply set your ISO or ASA, and see what aperture and shutter speed settings are recommended. An app such as this is a must-have for film photographers who don’t (or can’t) rely on any in-built metering system. Lumu is a very popular app for iOS that uses your phone camera as a reflective light and spot meter. Most of these apps are tested against traditional Sekonic or similar light meters to ensure the utmost accuracy. Fortunately, there’s a number of free light meter apps available on iOS and Android worth downloading and experimenting with. Light meters, though useful, can be particularly expensive to introduce to your photography kit. Evaluative, matrix or pattern metering: These are all names for the same metering technique (depending on camera manufacturer), which is similar to centre-weighted averaging but takes into account other factors including the focal point and other elements in focus within the scene. Partial metering: This mode works similarly to spot metering but will measure a larger (but not that much larger) portion of the scene, somewhere around 10%.Ĥ. Spot metering: Your camera will only measure the light of a very small part of the scene in spot metering, most commonly between 1% and 5% of the viewfinder image.ģ. Centre-weighted average metering: This mode prioritises the most important element of the scene, as the camera assumes its positioned centrally within the frame.Ģ. Depending on your camera manufacturer, these typically include the following:ġ. Historically, handheld light meters are used for studio photography to ensure supreme accuracy in a controlled lighting environment, or by landscape photographers hoping to achieve a wide dynamic range.īut you’re probably most familiar with the light metering modes available to you on a digital camera set-up. The light meter, being the ingenious piece of technology it is, takes all the guesswork out of the equation, calculating the appropriate shutter speed and aperture values in order to capture a correct and balanced exposure. This can be ambient light, reflected or direct light. A light meter is used to measure light in a scene in a number of ways.
