Pixels are tiny building blocks of color in an image; the more you pixels there are, the more detailed the image will be. A mega-pixel is a set of one million pixels; most DSLR cameras have a range of around 10 megapixels up to a mind-blowing 50 megapixels.

How many mega-pixels you have is not really the most important factor in getting good images, though. It sure is quite important in getting sharp images, but even more important is the lens, or "glass" that is used. For example, a camera with twelve megapixels paired with a very good quality lens will often have more detail than that of a 24 megapixel camera paired with a cheap lens. This all comes down to a factor called "Perceptual Megapixels," or "P-Mpix" for short.

Let's get this out of the way now- you will almost certainly never get all of the detail out of your camera sensor that it is capable of. A typical DSLR today has somewhere around a 24 megapixel sensor, but with the kit lenses that come with them, you only get about 9-13 perceptual megapixels of detail (Now you get it!). To get an image with a higher P-Mpix count, you have to use higher quality glass (lenses).

Sharpness can also be affected by factors like shutter speed, aperture, or ISO settings. If the shutter speed is not high enough on the camera, the image can be subject to motion blur. Aperture is also a very large factor in image sharpness. The aperture controls how much light enters the lens, and also the depth of field (the part of the image in focus). At apertures wider than about f/3.2, the image can become unsharp, and at apertures narrower than about f/7.1, the image can be subject to diffraction, which degrades sharpness.

What is image data?

When a person refers to image data, they are most likely referring to the internal code of a picture file that tells the computer information it needs to display the image, such as (but not limited to) what color the pixels in an image are, how many pixels an image has, and what image type it is.


2 How does the number of pixels affect the quality of an image?

A digital camera has a set number of pixels on its sensor. A pixel or picture element is a dot of light and color with a measured value for both brightness and color. The more present pixels, the more physical resolution is available and larger prints can be made with more physical detail. Too many pixels can result in overcrowding, forcing the pixels to struggle against the surrounding, occasionally reducing the overall quality (especially color and low light performance) of the image.

How many pixels in a standard photo?

A pixel is a bit of information in an image file. They do not relate directly to the size of the image. You may be confusing the concept of pixel count with the practice of expressing image dimensions in pixels. Generally speaking, the more pixels the better. The more information in the file, the more detail that can be included in the printed image, and the larger the image can be printed while maintaining good quality. Average pixel counts with newer consumer digital cameras run between 6 and 10 megapixels, as a rule. That translates to quality prints of at least 8 x 10 inches, and in many cases even larger.


Copiers Made By Canon?

Canon does make many very good copies. Quality is based on image and pixels in the copy. A better copier will make a clearer copy.


How many pixels in an image for printing?

Printing a photograph in a newspaper and printing a photograph in an art book will require very different image resolutions. For the newspaper 100 pixels per inch is OK for the art book 600 or more. So if your image is 5 * 8 inches the newspaper picture should be 500 * 800 pixels or 400 000 pixels, the art book greater than 15 million pixels.


How many pixels are in 100 KB?

This can vary wildly based on image format and other factors. For example, jpeg images can have smaller sizes (though lower quality) depending on how compressed they are. In the case of bitmaps, the amount of pixels that can fit into 100KB depends on its bit depth. A 1-bit 100K bitmap can fit 819,200 pixels. The 8-bit, 16-bit, 24-bit, and 32-bit bitmaps can fit 102,400, 51,200, 34,133, and 25,600 pixels, respectively. The general formula for how many pixels fit in an image of a certain size is as follows, for a bitmap: Pixels = [Size (in KB)] / [Bit Depth] x 8,192.


How many pixels are in one inch?

Depend on image resolution. You can see image resolution in Photoshop from Image > Image Size. Pixels are just the tiny dots that form images, they are not a form of distance measurement. To demostrate this, take for example a 40 in. TV. That 40 inch TV might contain 1920 x 1080 pixels to make up the screen, but likewise, a computer screen that is only 20 in. can also have the same amount of pixels.


How many pictures at 10 mega pixels will a 16gb memory stick hold?

It depends on how the images are encoded and the quality of the image. If they are JPEGs at high quality, then they will be around 4 megabytes each, so you would get around 4000 images on such a card.


How do you convert pixels into inches?

It isn't as simple as that. A pixel is 'PICture ELement' and has no set size value of it's own. It's kind of like asking how many bricks are in a metre - that would depend on the size of the brick. The only value that will aid you in working out how many pixels are in an inch would be the PPI (pixels per inch) value of the image you are working with. If you are working with an image that has a PPI value of 300, then there are 300 pixels in 1" of that image.
