Digital Camera and Printer
The Primer on Digital Camera Printers
Firstly, digital photo printers are available in two basic types. There are 4-color printers and 6-color printers. Nowadays, there are even 8-color printers available. Using good quality photo paper and one of the 8 color printers will give you results that rival your photo lab.
There are 2 main printing methods: inkjet and thermal. You need to have at least a 6-color printer to get decent print quality. · The printing width differs amongst printers. The highest quality printers will allow you to go larger but at a much higher per print cost.
· If you want to print really great looking black-and-white images, then the printer needs to have grey inks as well. · Whether your printer has separate ink tanks for each color or does it have multiple inks in each cartridge. · The printing speed per minute. Multi use printers are great for a busy office or household but if you want to make fine prints out of your digital images you should invest in a dedicated digital camera printer or digital photo printer.
Digital Camera Basics… Pixels
Digital images are composed of thousands or millions of tiny squares called picture elements, or pixels for short. Basically, the term megapixel means one million pixels, and it is used to describe the maximum number of pixels found in an image produced by a digital camera. More megapixels do not necessarily equal better images, they mean larger images (both in physical size and in file size).
All it means is that the maximum image size of the CX7525 is 2560 x 1920 and the maximum image size of the LS743 is 2408 x 1758. Larger image size may do nothing for a user who only wants to view images on his computer screen, or for use on the web, but the higher megapixel images are important for those looking to make prints of their images. Generally, higher pixel counts in an image translate to the ability to create larger prints.
Digital cameras use a small sensor to capture the image before transferring it to flash memory for storage. CMOS sensors are usually found in cheaper cameras and offer lower image quality than a CCD sensor that would probably be found in a more expensive camera.
Zoom – Optical and Digital
The quality of images produced using digital zoom suffer due to the nature of the process, and optical zoom is a far more desirable feature.
The price of a camera with optical zoom may be a good deal more than one with digital zoom, but the quality of the images cannot be compared. The Kodak CX7330 and the Kodak CX7300 are comparable cameras in many regards, but the CX7300 features only digital zoom, while the CX7330 features both optical and digital zoom for about $30 more.
Memory – Digital Film
Aliasing
Aspect Ratio
Aspect ratio describes the shape of a digital image, or any image for that matter, where the first number represents the width of the image and the second number represents the height. Standard film cameras generally use an aspect ratio of 3:2, but most digital cameras have adopted a 4:3 aspect ratio so that images better fit on a standard computer monitor. Connectivity
In general, cameras provide a cable to connect to a computer either via serial, USB, USB 2.0, or Firewire.
Some specialized cameras may take advantage of the high speed Firewire protocol for connecting to a computer.
