You should buy a camcorder with 800K or more below that is not worth it.
There is no one best HD camcorder for 100-300 for everyone. Each person has personal taste on which brands they like better. There are several very good HD camcorders including Canon and Panasonic.
For printing pictures the rule of thumb is ONE PIXEL is about 1/300 of an inch (i.e. there are 300 pixels per inch length-wise). For other media, this will vary accordingly. A good web-site to get additional information is www.auctionrepair.com. There are calculators on their page and a great deal of very good information about pixels in general.
There si no direct answer. It depends on the dpi resolution of the graphic device. Fr example a 300 dpi printer will have 300 pixels per inch.
Big as a breadbox
First you need to watch it if the camcorder is damaged. Many people see a camcorder and buy it without to see the camcorder. The Second thing is to test it does the camcorder works, and the third thing is to see the memory of the camcorder. If it has a small memory don'y buy it because you will need more than 200-300 mb.
There is no set amount of pixels, as that would depend on the picture file itself, as well as camera settings, etc. The generally accepted amount of pixels to get a nice clear print is 300ppi (Pixels Per Inch). In that case, we multiply 300 by 10 (the size of the print), which gives us 3000 pixels om the 10 inch side. Using that calculation for the 8 inch side as well gives us 2400 pixels. Now if we multiply the two (3000x2400) we get 7,200,00 pixels - which means that a camera of at least 7.2 megapixels will give us a nice and sharp 8x10" print.
At 300 dpi it would be 2,490 x 3,510 pixels.
I believe it's 1/300
This depends on the DPI/PPI (dots/pixels per inch).Web image-resolution is 72 DPI.Print resolution can be anywhere between 150-300 DPI.
A pixel usually has a known size, and there are many ways to figure it out. If it is a printed pixel, then it probably has a resolution of 300 or 600 dpi (or higher!), where dpi = dots per inch. So a 300 dpi pixel = 1/300 inches. To convert inches to centimeters, multiply by 2.54. So... a 300 dpi pixel = 1/300 inches = 1/300*2.54 cm = 0.00847 cm For a computer monitor pixel, if you don't know your monitor's dpi, you can measure the width of your screen in centimeters (for example, mine is 40 cm wide... be careful, most monitors are sold using a diagonal dimension). Then, figure out the maximum horizontal resolution of the monitor (look in your user guide if you don't know, but for example, let's say 1600 pixels). The pixel size is then (40/1600) cm = 0.025 cm
Scan it in using a scanner at 300 to 600 pixels per inch
Sony HD camcorders come in a broad range of quality and features. A lower end one will cost around $200 or $300. A higher end Sony Camcorder can easily cost over $1,000.
