Image resolution

Is the most talked about feature of a digital camera. From 3 to 12 megapixels or more, it seems that with every generation of digital camera there is an increase in image resolution.

But what is a megapixel? Well, a megapixel is represented by 1000000 pixels.

So, if the maximum resolution of a digital camera, results in an image 3000 pixels in width and 2300 pixels in height, that camera would be a 3000 x 2300 = 6900000 / 1000000 = 6.9 MEGAPIXELS

When talking about megapixels, there is the question: how much do you need? Especially because the more a camera is capable, the more expensive it is.

If you are going to use the images on the Internet, you may find that the maximum resolution of 1600 x 1200 might be enough. That would lead you to buy a 1.92 MPx camera!

If you want to print an image, you need to consider the dpi requirements. 300 dots per inch is a standard in printing any image. It simply means that all you have to do to find out the maximum width of a printed image is to divide its width in pixels by 300.

3000 pixels / 300 = 10 inches maximum.
