The size of any picture in pixels depends on how the picture is taken. You can take the picture to have as many or as few pixels as you want.
To determine the number of pixels in a picture, you can multiply the width of the picture in pixels by the height of the picture in pixels. This will give you the total number of pixels in the image.
To determine the number of pixels in a 2 by 3 picture, you need to multiply the width by the height. If the dimensions are in inches, for example, the pixel count would depend on the image's resolution (DPI). However, if you're simply referring to a grid of 2 by 3, it consists of 6 individual units or "pixels."
The number of pixels in a 4x6 picture depends on the resolution (DPI - dots per inch) used. For example, at a resolution of 300 DPI, a 4x6 picture would be 1200x1800 pixels, resulting in a total of 2.16 million pixels. At 72 DPI, it would be 288x432 pixels, totaling about 124,416 pixels.
For a picture to be used as an iOS wallpaper, it must be at least 1136 x 640 pixels.
It depends how detailed the picture is
the larger the pixels the more compact the picture is so you dont see the little dots because there are more squares in the picture. so the higher the pixels the better the picture becomes. there are a million little dots in a pixel when you take your picture so if you have 3 pixels 3 million little dots in the picture the better quality.
Mega pixels to you a picture tells how big it is. digital photos of small points in the name of pixels and each of these pixels can immediately different color and Light.
it determines the resolution of the picture. the higher the pixels, the clearer the picture.
The image resolution of a picture is broken into pixels. The amount of pixels in the picture depends on the size of the print. There are approximately 100 pixels per inch in a picture.
Because there are so many pixels I expect
