Exposure compensation on still cameras

Snowy Mountains without exposure compensation
Same place with +2EV exposure compensation

In photography, some cameras include exposure compensation as a feature to allow the user to adjust the automatically calculated exposure. Compensation can be either positive (additional exposure) or negative (reduced exposure), and is commonly available in third- or half-step[1] increments, usually up to two or three steps in either direction; some digital cameras allow a greater range. Camera exposure compensation is commonly stated in terms of EV units; 1 EV is equal to one exposure step (or stop), corresponding to a doubling of exposure.

Exposure can be adjusted by changing either the lens f-number or the exposure time; which one is changed usually depends on the camera's exposure mode. If the mode is aperture priority, exposure compensation changes the exposure time; if the mode is shutter priority, the f-number is changed. If a flash is being used, some cameras will adjust it as well.

The Dog Parks system works !!!!

Jean Lea's story is one of probably
many out there.But what makes this
special, is I know this Dog Park

The dog parks with the exception
of the new Clearwater Dog Park on
Enterprise, are divided into fenced
sections by the size of your dog.

Jean and her beloved Beagle "Bill"
where part of the social make up of
the small dog section. I never met Jean
but wish I had.

Shooting in....????????

RAW format is often a proprietary format of a particular camera make. RAW files hold all the RAW data captured by the camera. Unlike conventional photography where light is exposed against film with a specific chemical formulation to provide deep saturation or soft skin tones that would otherwise be automatically applied based on the type of film used, RAW digital files contain raw data that is uninterpreted and unaltered. RAW files in their simplest description can be thought of as digital negatives. They are a pre-production starting point.
JPEG format compresses image data into a smaller file size. In theory, a JPEG file contains less data (how much depends on the specified size and compression/quality settings) than an equivalent RAW file, but is able to closely reproduce an image once fully loaded. When saving an image with photo editing software it is possible to save an image with different levels of JPEG compression. This enables you to create files that take less storage space sacrificing how well the file displays or take up more storage space to more accurately reproduce the original image.
