What do megapixels and high resolution do? Easy 10 points?

Question

What do they do to enhance your camera. And what are they basically?

Answer 1

Most simply, it makes your picture is more clear with higher resolution and greater number of megapixels. A large number of megapixels would be considered high resolution.

Pixels are little dots of color that make up a digital picture, like dots of ink in newsprint. The more the camera takes, the more clearly the picture is defined. Also, the more pixels there are, the closer you can zoom in/enlarge the picture.

For general use, (like say family vacations or holidays), a four megapixel camera is more than ideal. A four megapixel will give you atleast clear 5"x7" prints and decent 10"x12". You shouldn't pay more than $200 for a four megapixel digital camera, either. Check Walmart because they have a good selection and good prices.

I have a 4 megapixel Vivitar camera and it's just great. It's very simple to use. Minimal buttons and very durable.

If you can get more than 4 megapixels (say a 5 or 6) for under $200, than that's more bang for your buck!

Good Luck! Hope this helped!

Answer 2

digital photos are made up of pixels. each pixel holds 1 bit of information so the more pixels you have, the more information in your photo and the better quality your image is.

mega is the greek prefix meaning 1000000 or a thousand thousands. like in bytes, 1000 bytes is 1 kilo byte and 1000 kilobytes is 1 mega byte.

for cameras, say you have one that shoots 640x480 pixels (or your typical low web cam or low-end phone) multiply these two and you get 307200 which is .3 megapixels.

1280x1024 pixels (or your average monitor resolution) comes out to 1310720 or 1.3 megapixels.

these days, your average phone can take 2 mp, your average digi cam can take about 5 mp. (though I've heard some go up to 10 mp which is fairly large) professional digicams can go up to 40 mp.

resolution is basically the pixel count. the highness or lowness of resolution will be relative to what you'll use the image. in my line of work, 1280x1024 (or 1.3 mp) is very very low resolution. though for web use, it's considered high resolution already.

rule of thumb is the higher the mega pixel count, the sharper/better the image, but this will also enlarge the file size.

Answer 3

For normal 4x6" (10x15cm) prints, even 0.3MP is just fine. Digital cameras did this back in 1991!

In 1999 when digital cameras were only 1.2 or 2 MP, each megapixel mattered if you were making bigger prints.

Today, even the cheapest cameras have at least 5 or 6 MP, which enough for any size print.

Sharpness depends more on your photographic skill than the number of megapixels, because most people's sloppy technique or subject motion blurs the image more than the width of a microscopic pixel.

Even when megapixels mattered, there was little visible difference between cameras with seemingly different ratings. For instance, a 3 MP camera pretty much looks the same as a 6 MP camera, even when blown up to 12 x 18"! I know because I've done this.

Joe Holmes' limited-edition 13 x 19" prints of his American Museum of Natural History series sell at Manhattan's Jen Bekman Gallery for $650 each. They're made on a 6MP D70.
