Photography 101 The Basics Of Metering And Exposure

Typical humans see their world in 16 “f-stops”, or measurements of light reflecting off their environment. Cameras see no more than 5 stops at once. So the more contrast there is in the scene, the more stops of light there are to BE seen. This concept means that correct exposure on your camera is critical to avoiding under- or over-exposure. To understand how a camera measures this light, lets start with the proper definitions of Exposure and Metering.

Exposure
Exposure is the quantity of light allowed to act on a photographic material. It is a product of the intensity, which is controlled by the lens opening (aperture), and the duration (shutter speed) of light striking the film or paper. Your ISO setting, your aperture size, and your shutter speed directly impact the exposure of an image.

Metering
Metering is the process of calculating the best exposure from the existing light conditions.

When your digital camera meters a scene, it measures the amount of light in the scene and calculates the best-fit exposure value based on the metering mode (see below for details). All meters are designed to produce midtone results – neither black nor white, neither light nor dark, but somewhere in between. Metering systems are typically calibrated to a value of 18% gray because a typical scene reflects the same amount of light as this gray value. As a result, scenes with high contrast can give the automatic exposure a difficult time.

The metering mode on your camera defines which information in the scene is used to calculate the exposure value. Metering modes depend on the camera and the brand, but are mostly variations of the following three types:

1) Spot (Partial) Metering
Spot metering is a method of metering that only uses a small spot in the centre of the composed scene. The size of the spot varies with the brand of camera, but typically ranges from 1% to 3.5% of the image area. Partial metering covers about 9.5%. Spot metering allows you to meter the subject in the center of the frame (or on some cameras at the selected AF point). This type of metering is useful for brightly backlit, macro, and moon shots. Use this metering method when your scene has significant differences in brightness (e.g. between foreground and background) or for subjects that require precise measurement, such as close-up photography.

2) Center-weighted Average Metering
Center-weighted metering is averaged over the entire scene with emphasis placed on the center area (typically 75% based on lighting conditions at the center and 25% outside). It assumes that you will be composing with the subject in the middle of the frame and most of us know this is not always the case. Center-weighted metering is probably the most common metering method implemented in nearly every digital camera and the default for those digital cameras which don’t offer metering mode selection. Most centre weighted systems have greater sensitivity in the bottom half of the frame, which, when used in landscape format, cut down the influence of the bright sky on the exposure. Be careful when using this mode for portrait photography when the camera is turned on its side.

3) Matrix or Evaluative Metering
Matrix was introduced to the world in 1988 with the Nikon F4. This is probably the most complex metering mode, offering the best exposure in most circumstances. Essentially, the scene is split up into a matrix of 3 to 16 or more, typically 6 metering zones which are evaluated individually, taking into account such factors as the focusing point in use, subject size, position, distance, overall lighting level, front and back lighting and color. The overall exposure is based on an algorithm specific to that camera, the details of which are closely guarded by the manufacturer. Often they are based on comparing the measurements to an on-board database of images. Matrix metering uses a microchip that has been exposed to literally thousands of picture-taking situations. As you point the camera towards your subject, matrix metering recognizes its light/dark pattern and reads the light accordingly.

If you test your spot meter on various parts of a scene youve composed, youll no doubt prove to yourself that there is a vast range of light and shadow, but since the film or digital card cannot record more than a five stop range, what difference does it make? You will still end up keeping the same two or three exposures that were created using center-weighted or matrix metering.

Both center-weighted and matrix metering prove accurate in 90% of one’s picture taking efforts. That should boost your confidence in choosing them when you realize that nine out of ten pictures will be a correct exposure! In either center-weighted or matrix metering modes, you can aim, meter, compose, and shoot when your subject is frontlit, sidelit or under an overcast sky.

Donald Duck is a typical white duck with an orange beak, legs and feet. You will usually only see him in his sailor shirt, cap, red bow tie and no trousers. Mickey Mouse is the most popular cartoon character of all time, followed by Bugs Bunny and Donald Duck comes in at a close third.

His most famous feature is his nasal voice. This was done by Clarence “Ducky” Nash right up to his death in 1985. Since 1985 the voice has been done by Tony Anselmo, who was trained by Clarence for the role. Donald Duck’s screen personality was created by Dick Lundy, who is a wonderful animator.

Donald also has an extensive cartoon family including his nephews Huey, Dewey and Louie, who cause him even more irritation. His mother is Hortense Mcduck and his father is Quackmore Duck.

Is That Sound Your Train Horn

Has a sound you’ve never heard before ever scared you completely out of your wits? It’s happened to me! “Train horns” are the latest craze, and they’re becoming more and more popular every day. The first thing I asked was, “why?” That’s a good question, I thought, but the answer should be obvious. Train horns are loud, and unless the sound they produce is kept within the decibel levels allowed by regulations, they can be very, very loud. First off… what is a train horn, anyway? It’s an air horn device used to provide a warning and is used by electric and diesel locomotive passenger trains, along with other railroad vehicles.

“Train horn” is a self-explanatory name. These devices were first used on trains, but they later began to also be used on fire trucks and ambulances, and then on large trucks. They were used to warn people that an emergency vehicle was approaching and to instruct them to move out of the way. They are extremely effective and fire trucks still use them today. Fire trucks now tone down the sound of their air horns with shutter tone, however.

Many people say train horns on cars warn other drivers on the road that you are approaching. Well, of course! Train horns come in a lot of different models and kits to choose from. You can mount one on your truck, van or car. Along with the horn, a train horn kit includes the valves and tubes needed for installation. The cost of train horns ranges from as low as $100 to more than $800.

We don’t need to stop there, either, because you can get accessories for your current train horn or a train horn you might be thinking about buying in the near future. These accessories include things like triple horns, air tanks, pressure switches, compressors and replacement solenoids.

Installation is simple. Train horns can be mounted on many areas of your car, including in your trunk, under the hood, and on the roof. They can be installed pretty much anywhere there’s enough room. The vehicle you have will decide which model or style of horn you should get. Most people use their train horns as an accessory. Many cars look almost the same, but a train horn mounted on the outside of your car can really make it stand out in a big parking lot.

There are recommended decibel levels for these horns, because high levels can be dangerous to animals and humans. It is necessary to keep the horn’s decibel level within legal requirements to avoid this type of situation. This is the responsibility of each train horn owner to use this product in a reasonable manner to avoid any hazardous situations from developing.

Finding Podcast Hosting

For anyone who wants to begin creating a podcast, podcast hosting is the most important part. Before anyone can begin distributing a podcast, they need a place to store the files and keep the feed file that will tell their subscribers about the new episodes available. The first thing required is a domain name where the site will be located. Many domain registrars are available who will help one register a domain name for a small fee. Once the domain is registered, hosting is required, and again there are many different companies willing to do the hosting for a small fee. One of those is bluehost.com, but many others are available. When looking for a host, the most important thing is to make sure that a lot bandwidth and storage space is available and cheap. Since podcasting deals with large media files, a lot of disk space will be taken up storing the files and bandwidth will be eaten quickly when they are downloaded by the subscribers.

After podcast hosting has been acquired, it needs to be used and the site needs to be set up. The DNS addresses of the site need to be set to the addresses that the host provides you so that the servers that underlie the
internet will know where your site is. DNS addresses can be set by going to the domain registrar that was used to acquire the domain and inputting the addresses provided by the host. After that is done, it will take a
few days before the master list the domain registar updates will be shared throughout the internet and all name servers know where to find your specific domain. You can then go about setting up your own podcast.

Using the podcast hosting you now have, you will need to look at the disk space allocated to the site using something called and FTP browser. The host may provide one as part of their hosting plan, but if not there are many available free to choose from. Using the FTP browser, log on to the host and upload a file called dircaster.php after editing it to fit the specifics of the
site. Dircaster.php is an easy to find piece of coding that generates a feed file by looking at the contents of its directory or folder. The individual episodes to be podcasted can then be uploaded to the same folder as dircaster.php for cataloging. Make sure that all the meta data, or information about the mp3 file is correct before doing so.

The podcast hosting you now have will allow you to distribute a podcast. It would be best to upload more to the site, such as an index page that tells visitors about the podcast and provides the address of the file dircaster.php on your site. When they subscribe to that file, the podcast client thy use will access it and recieve information about the latest podcasts available.
