Photography Information

Resolution or mega pixels is the way digital cameras are rated. Not all 5 megapixel cameras are created equal. A 5 megapixel camera from lets say Nikon may produce higher quality pictures than a budget manufacturer. Below is a guide for helping you to determine what your needs are.
- 640×480 – This is the low end on most “real” cameras. This resolution is ideal for e-mailing pictures or posting pictures on a Web site. Anything with less resolution is not worth talking about. Not worth buying.
- 1216×912 – This is a “megapixel” image size — 1,109,000 total pixels — good for printing pictures.
- 1600×1200 – With almost 2 million total pixels, this is “high resolution.” You can print a 4×5 inch print taken at this resolution with the same quality that you would get from a photo lab.
- 2240×1680 – Found on 4 megapixel cameras — the current standard — this allows even larger printed photos, with good quality for prints up to 16×20 inches.
- 4064×2704 – A top-of-the-line digital camera with 11.1 megapixels takes pictures at this resolution. At this setting, you can create 13.5×9 inch prints with no loss of picture quality.

The simplest camera on the current market is the lens-shutter camera, also known as a point-and-shoot camera. These cameras are easy to use, give good results, and are extremely affordable.
Point-and-shoot cameras are very automatic: auto flash, auto exposure, auto wind, auto rewind, and auto shutoff. Taking pictures is a snap! Look through the viewfinder, press the button, and the camera captures the picture. The camera selects the shutter speed and aperture for you.
Point and shoot camera have long been the favorite for family and vacation pictures. The flash has a limited range, usually 10 to 15 feet, which is ideal for birthday parties and holiday celebrations. In the corporate world, point-and-shoot cameras are ideal for ID cards, employee newsletters, real estate brochures, and for loading simple images on the Internet.
Not a Point & Shoot. Not an SLR. It’s a PEN.
Shooting the special images of your daily life usually means snapping small, grainy images with your cell phone or using a point-and-shoot if you have it with you. A DSLR delivers incredible image quality, but most aren’t compact enough to take with you. Now, the Olympus E-P1 changes the game with a compact body that delivers the professional quality images of a DSLR without the bulk. Even better yet, its sharp HD video capture and stereo audio helps you live a better-documented life because you’re carrying one portable camera rather than a DSLR, an HD camcorder and a high-end audio device.
With interchangeable lenses and attachments such as the flash attachment. The posibilities are enless. This item is available for preorder. This is one hot camera and will revolutionize the photography world.
When shooting landscapes through bushes or trees use a fill flash to highlight the fore ground. See example at left. This will be difficult with most point and shoot cameras some will and some will not. You may need a mid range camera (like the Sony DSC-10 or better to do this. The macro setting will set the flash but your depth of field will be short. That is that the distance will be blurry or distorted.
As you can see the leaves of the trees are highlighted and give a real cool effect. Normally the leaves would appear dark and of not much interest. With the fill flash it brings out the leaves and gives a unique look for your pictures. Try it for yourself and play around with it. Digital photos are easy to delete.
A camera is a device that records images, either as a still photograph or as moving images known as videos or movies. The term comes from the camera obscura (Latin for “dark chamber”), an early mechanism of projecting images where an entire room functioned as a real-time imaging system; the modern camera evolved from the camera obscura.
The history of photography is fairly recent. The first permanent photograph was made in 1826 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris
A point-and-shoot camera, also called a compact camera, is a still camera designed primarily for simple operation. Most of them use autofocus or focus free lenses for focusing, automatic systems for setting the exposure options, and have flash units built in.
Point-and-shoots are by far the best selling type of camera. They are popular with people who don’t consider themselves photographers but want an easy to use camera for vacations, parties, reunions and other events.
Point-and-shoot cameras are distinguished from single-lens reflex cameras (SLRs) in several respects: The image that the photographer sees through the viewfinder of a point-and-shoot camera is not the same image that passes through the primary lens of the camera (that is, the lens that projects the image onto the film or, in the case of digital cameras, the image sensor). Rather, the image in the viewfinder passes through a separate lens. SLRs, on the other hand, have only one lens, and a mirror diverts the image from the lens into the viewfinder; that mirror then retracts when the picture is taken so that the image can be recorded on the film or sensor. It is because of this method of diverting the image into the viewfinder that pictures cannot be previewed on the LCD screens of most digital SLRs, although some manufacturers have found a way around this limitation. Digital cameras obviate the need for the SLR design to some degree, as the camera’s LCD image is projected through the lens, not a separate viewfinder. Many newer digital point-and-shoots even leave off the optical viewfinder entirely
