This is a common feature on top of many cameras made in the past 100 years. The precise dimensions of the shoe vary from camera to camera so if initially if the fit of your meter is tight, it will “wear” slightly over the first several uses and become more free-moving. This is not a problem as there are integrated lever springs to ensure the meter does not fall out of the camera mount. -
Ground-Based Photographic Monitoring
United States Department of Agriculture Ground-Based Forest Service Pacific Northwest Research Station Photographic General Technical Report PNW-GTR-503 Monitoring May 2001 Frederick C. Hall Author Frederick C. Hall is senior plant ecologist, U.S. Department of Agriculture, Forest Service, Pacific Northwest Region, Natural Resources, P.O. Box 3623, Portland, Oregon 97208-3623. Paper prepared in cooperation with the Pacific Northwest Region. Abstract Hall, Frederick C. 2001 Ground-based photographic monitoring. Gen. Tech. Rep. PNW-GTR-503. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 340 p. Land management professionals (foresters, wildlife biologists, range managers, and land managers such as ranchers and forest land owners) often have need to evaluate their management activities. Photographic monitoring is a fast, simple, and effective way to determine if changes made to an area have been successful. Ground-based photo monitoring means using photographs taken at a specific site to monitor conditions or change. It may be divided into two systems: (1) comparison photos, whereby a photograph is used to compare a known condition with field conditions to estimate some parameter of the field condition; and (2) repeat photo- graphs, whereby several pictures are taken of the same tract of ground over time to detect change. Comparison systems deal with fuel loading, herbage utilization, and public reaction to scenery. Repeat photography is discussed in relation to land- scape, remote, and site-specific systems. Critical attributes of repeat photography are (1) maps to find the sampling location and of the photo monitoring layout; (2) documentation of the monitoring system to include purpose, camera and film, w e a t h e r, season, sampling technique, and equipment; and (3) precise replication of photographs. -
Tip Sheet – Lumen Meter
TIP SHEET – LUMEN METER What is a lumen meter? A light meter or lumen meter is a device used to measure the amount of light in a certain area. Lumen meters have many uses such as photography and cinematography, however for our purpose we want to help reduce the amount of wasted light which equals wasted electricity. If conducting an outdoor lighting audit the purpose of a lumen meter would be to reduce the amount of light pollution. Light output is typically measured in luxes or lumens. Sometimes you will hear the word footcandles. This is another standard unit of measure that is used interchangeablely with the term lumen. Ehow.com defines a lux as a uniform standard by which the amount of visible light present in a given space can be described where as a lumen is a measure of just how much visible light is produced by an object such as, for example, a light bulb. 1 footcandle/lumens = 10.76 luxes and 1 lux =.093 footcandles or lumens Where can I purchase a lumen meter? Eco-Schools USA recommends the light meter from Mastech found on Amazon.com. http://www.amazon.com/Mastech-Light-LX1010BS-display- Luxmeter/dp/B004KP8RE2/ref=sr_1_5?s=electronics&ie=UTF8&qid=1342571104&sr=1-5 Mastech Light Meter LX1010BS with LCD display, 100,000 Lux Luxmeter - $20.17 Operating directions Mastech Light Meter LX1010BS with LCD display, 100,000 Lux Luxmeter operating instructions are found on the next page. The unit of measure displays in luxes. This will be a great opportunity for your student to work on conversions. -
Exposure Metering and Zone System Calibration
Exposure Metering Relating Subject Lighting to Film Exposure By Jeff Conrad A photographic exposure meter measures subject lighting and indicates camera settings that nominally result in the best exposure of the film. The meter calibration establishes the relationship between subject lighting and those camera settings; the photographer’s skill and metering technique determine whether the camera settings ultimately produce a satisfactory image. Historically, the “best” exposure was determined subjectively by examining many photographs of different types of scenes with different lighting levels. Common practice was to use wide-angle averaging reflected-light meters, and it was found that setting the calibration to render the average of scene luminance as a medium tone resulted in the “best” exposure for many situations. Current calibration standards continue that practice, although wide-angle average metering largely has given way to other metering tech- niques. In most cases, an incident-light meter will cause a medium tone to be rendered as a medium tone, and a reflected-light meter will cause whatever is metered to be rendered as a medium tone. What constitutes a “medium tone” depends on many factors, including film processing, image postprocessing, and, when appropriate, the printing process. More often than not, a “medium tone” will not exactly match the original medium tone in the subject. In many cases, an exact match isn’t necessary—unless the original subject is available for direct comparison, the viewer of the image will be none the wiser. It’s often stated that meters are “calibrated to an 18% reflectance,” usually without much thought given to what the statement means. -
Camera Basics, Principles and Techniques –MCD 401 VU
Camera Basics, Principles and techniques –MCD 401 VU Topic no. 49 Film Exposure Exposure in film photography is defined as the quantity of light that is allowed through the camera lens and onto the photo film controlled by the intensity of light (through the aperture) and length of time (determined by the shutter speed). For correct exposure in a film camera, whether 35mm, medium format, or large format, it is essential that you correctly set both the shutter speed and aperture. Film speed will also play a role in determining the correct exposure. Obtaining the Correct Film Exposure Technically speaking, the correct film exposure does not exist as different photographers will have a different idea of what is properly exposed and what is not. See the example below for three different exposures of the same site. Depending on whether you want to see all the detail or darken it for night will determine the right exposure for you. However, the way in which you get any exposure remains the same. Light Metering Most modern 35mm single-lens reflex (SLR) film cameras have through-the-lens (TTL) meters that intake the amount of light available to help you determine the best exposure. These types of light meters are called Reflective Meters as they measure the light bouncing off your subject and into the camera lens. For beginners using a camera without a light meter, it is highly suggested that you purchase a handheld meter to use. Handheld meters can be Reflective or take 1 Camera Basics, Principles and techniques –MCD 401 VU Incident Light Readings. -

Average Scene Reflectance in Photographic Exposure Metering Douglas A
Average Scene Reflectance in Photographic Exposure Metering Douglas A. Kerr, P.E. Issue 1 January 30, 2005 ABSTRACT The quantity “assumed average scene reflectance” is widely mentioned in connection with the calibration of “reflected light” photographic meters. Understanding of its significance is elusive. In this paper, we examine the actual significance of this quantity and how it plays a role in deciding upon a calibration constant for a reflected-light exposure meter. We also examine the significance of various oft-mentioned values of assumed average scene reflectance, such as 18% and 12-13%, and finally discuss the use of a gray card of known reflectance to perform “incident light” metering using a reflected light meter. SUMMARY The quantity “assumed average scene reflectance” is widely mentioned in connection with the calibration of “reflected light” photographic meters. Often questions are raised as to exactly what that means, and as to what numerical value has likely been used in establishing a calibration for a particular exposure meter or in-camera metering system. Also of interest is the matter of using a “gray card” target to perform incident light metering with a reflected light meter. The question is often raised as to what reflectance is most appropriate for direct use of such a card. We conclude that: • The matter of the significance of the average scene reflectance assumed in the calibration of a reflected light meter is not a simple one. • The value of assumed average reflectance of a “typical” scene upon which the calibration of reflected light meters is predicated is commonly 18%. -
