Meaning of main digital camera terminology
This is a list of some of the main terms for using a digital camera
- Pixels: Are the smallest piece of information that make up an image. It is represented by a single "dot or square" of light or ink. Every pixel has its own different colours and each pixel can have up to four colour components.
- Megapixels: Is a measurement of digital photo quality and one megapixel contains one million pixels. A 1600x1200 pixel image size is a common size and is said to have "1.9 megapixels" (1600×1200 = 1,920,000)
- A 5 Megapixel digital camera: A camera capable of shooting an image measuring five million pixels in size.
- Pixel Count: The amount of pixels that an image contains is called the pixel count. An image will look better the more pixels you have.
- PPI: Or pixels per inch", is a term used to describe an element in picture quality. It indicates a set amount of pixels in a specific area to be printed. If the number of pixels per inch that is displayed is higher the better the image will be to the human eye.
- Aperture: Controls the depth of field through an opening where light is allowed into your camera. This opening behind the lens permits light to travel to the digital camera's interior where the sensor is located.
- Digital Camera Memory: Digital images or photographs are stored in a location called memory. Built into your camera for the purpose of storing images this electronic storage space is in the form of SmartMedia Cards, XD Cards, Secure Digital Cards, Compact Flash Cards. In general the sizes of a digital camera memory are 64 MB, 128 MB, 256 MB, 512 MB, and 1 GIG.
- Digital zoom: The process of digitally enlarging a portion of the picture by decreasing (narrowing) the apparent angle of view of a digital photographic or video image. This function is accomplished within the electronics of the digital camera without any physical adjustment of the camera's optical lenses, but results in a loss of picture quality.
- Optical Zoom: Is the ability of a lens to change its focal length and enlarge a view it is the opposite of Digital zoom in that it uses the physical properties of lens assemblies. It is a better option than a digital zoom as it does not alter the quality for a recorded image.
- JPEG: The perfect file format used for compact storage of groups of pixels in a photograph. This particular compression ratio was fixed by the Joint Photo Experts Group to reduce the picture size. The degree of compression can be adjusted however, the higher you compression your image will result in a larger loss of picture quality.
- TIFF: An uncompressed image storage file format. "Tagged Image File Format" is the longer version. While there is no loss of information in this format, the resulting file sizes are also very large.
- Digital Camera Sensor: The digital imaging sensor converts incoming light into an electrical signal then into a digital image you can then view and print. It performs the role of "re-useable negative" within a digital camera.
- Shutter Speed: Is a term which is used for the aperture exposure time that allows light into your camera when opened. The aperture is open longer with longer shutter speeds, this results in more exposure because there is more light.
- White Balance: To correct all the colours in an image white balance is used to account for the intensity of light an image was taken in. Various reasons contribute to the intensity of light. However modern digital cameras usually have preset values you can
- Switch on to compensate for the different light intensities which then calculate all other colours based upon this setting.
- RAW/NEF: Is the uncompressed image as shot by a digital camera before processing. Sometimes called digital negatives Raw image files were invented by Canon while NEF came from Nikon.
What digital cameras are best using existing light wihout flash after sunset?
I have two digital cameras - panasonic tz3 and canon S2 IS - but I am not happy with the grainy picture quality I took using existing light indoor and outdoor after the sunset.
I see that the camera lens are not fast lens, like 1.8 or 1.4...
Hi, I'm assuming these are both point & shoot (P&S) cameras. Yes?
While these are both top quality brands of cameras (including P&S's), it is just the nature of P&S cameras that it is tough to get high quality photos in low light. Their electronics just aren't as sophisticated as bigger DSLRs and their processor sizes are smaller - so they can't store the same density of info as the bigger cams. They also have small flashes - so you're not able to cast more light to improve the image capture process.
One thing you can do to give yourself a fighting chance at improving quality in low light is to use a tripod. There's a much greater chance to enhance blur in low light. The tripod (or a monopod) would help take that issue off the table.
If your cameras have a "Night" or "Night Portrait" mode, have you tried them to see if that helps? Since you're playing with digital, and therefore not wasting money on film, also experiment using the "Portrait" mode. In portrait mode cameras typically open up the aperture to achieve a shallow depth of field (e.g, they make the aperture setting bigger to let in more light). Try using that (also with camera on stabilizing device) to see if that helps at all.
At some point, if you're serious about photog vs. just capturing fun memories in snapshots, think about moving up to a DSLR. It will help eliminate the problem you're experiencing with the P&S''s.
Take care...

# The Charge
Does a new earth mean a chance at another life?
# Opening Statement
"What would we really like to see if we could stand outside ourselves and look
at us?"
# Facts of the Case
Rhoda Williams (Brit Marling, **Community**) is an exceptionally gifted high
schooler who has just been accepted to MIT. To celebrate, she engages in a
night of drinking and partying with her friends. Alas, she foolishly decides
to drive home by herself while intoxicated, and crashes into another vehicle
as a result. The accident puts John Burroughs (William Mapother, **In the
Bedroom**) into a coma; Burroughs' wife and child are killed. After John
recovers, Rhoda determines to find a way to make amends.
Meanwhile, a major cosmic event is taking place. Another earth has appeared in
the sky; a world which seems to be identical to our own. A trip to "Earth 2"
is being planned, and an essay contest is being held to determine which
individual citizen will be permitted to go along with the official team. Rhoda
enters the contest, hoping she'll have a chance to meet up with an alternate
version of herself.
