Ok Im a film person and a computer person but some of the terms people use now days leave me a bit perplexed so how about a thread with some of these terms defined.
Like the word and either a explanation or a link to one
HDR = high dynamic range
http://en.wikipedia.org/wiki/High_dynamic_range_imaging
Bokeh - The fuzzy out of focus part on pictures with short depth of field.
Pan - Rotating the camera from left to right or right to left, usually while standing or keeping the tripod in the same position.
Tilt - Rotating the camera up and down, usually while in the same position.
Zoom - Using the zoom lens on a camera to zoom in or out on the subject, usually with a stationary camera.
Digital Zoom
Digital zoom brings you closer to your subject by using software to enhance the field of view. A side effect of digital zoom is a noticeable reduction in image quality.
Face Detection
Instead of simply focusing on the closest thing in the frame, as most point-and-shoot digital cameras will do, face detection looks for and focuses on patterns that appear to resemble the human face. By having the subject’s face, and particularly their eyes in focus, you obtain a more striking photograph.
LCD
The display on the back of the camera that is used to compose and review photos.
Image Stabilization (IS)
A feature that increases sharpness in photos by counteracting motion blur caused by the photographer’s hand movement. Note: IS cannot prevent motion blur from a moving subject, nor blur from extremely exaggerated hand movements.
ISO
An ISO rating indicates how sensitive a digital photo sensor is to light. Low ISO numbers require slower shutter speeds, and produce sharp photos. Using a high ISO number enables a faster shutter speed, but produces a grainy, “noisey” photo. High ISO is often essential for taking indoor photos without flash. A camera rated at 3200 ISO will allow you to use a sensitivity from 50 or 100, all the way up to 3200.
Macro Photography
Cameras with macro capability can be used to take sharp, life-size photos of small subjects like insects and tiny flowers.
Megapixel
Digital photos are made up of small units called pixels. A megapixel is one million pixels. A camera with a small megapixel rating (say 1 or 2 mp) will produce photos that lack detail. Photos from a 6 or 7 megapixel camera are generally considered acceptable for large prints.
Memory Card
A removable storage device for recording digital photos. Many cameras come with a small amount of built-in storage, and require the purchase of an extra memory card in order to hold large amounts of photos.
Noise
Noise refers to the appearance of grain in a photograph, resulting in a loss of sharpness. Noise is a side effect of using high ISO numbers.
Noise Reduction
The use of software to increase sharpness and picture quality by reducing noise.
Optical Zoom
Optical zoom brings you closer to your subject by adjusting the elements inside the camera’s lens. Optical zoom produces image quality superior to digital zoom.
PictBridge
A technology that allows photo printing directly from camera to printer, without requiring the use of a computer.
Shutter Lag
The amount of time between the moment the photographer press the shutter button and when the camera actually begins taking the photograph. Long shutter lags cause missed photos.
Telephoto
A lens that brings you closer to a distant subject; good for use in sports and wildlife photography. Cameras manufacturers often use phrases like “4x zoom” or “10x zoom” to indicate telephoto capabilities. The larger the number, the closer you get to the subject.
Vibration Reduction (VR)
See Image Stabilization (IS).
Wide Angle
Have you ever looked through a camera’s viewfinder and noticed that the field of view appears farther away than when seen with the naked eye? You are looking through a wide-angle lens. Wide-angle lenses are popular for dramatic landscapes and indoor group photos.
Chimping: Checking the photo (on the LCD screen) each time after every shot to ensure the photo came out good (e.g. proper exposure, good framing, etc).
dSLR: Digital SLR. (See SLR definition above in post)
PP: Post Processing -tweaking the picture (remove red eye, color correction etc.) with software from the camera manufacturer or with one of many aftermarket digital photo software's.
Gaffer Tape (AKA "Gaff Tape") in indispensable tape that'll hold or fix about anything. Vastly superior to "duct tape" in the quality of the adhesive as it will not leave a sticky residue to things it is used on or quickly harden over time.
A couple that will date yourself if you get...
Stop Bath The darkroom chemical used to stop the development process on negatives and prints whose active ingredient is acetic acid (also found in vinegar). Usually sold in highly concentrated form which is commonly used in the "initiation" of new people working in the darkroom... "Hey, get a whiff of this!!!" (followed by the victim acting like their nose hairs have been set on fire.)
RC Paper Resin Coated photo paper. A godsend product that allowed you to get glossy photos with quick air drying, but heaven help the poor guy that fed a piece into their drum dryer by accident!
Ilford A UK-based company that made B&W film and paper that could kick Kodak's stuff around the block.
LINK with alot more but still missing some I see here.
