The higher the resolution of the picture the clearer the picture, if a 300 resolution picture in the enlargement, the picture will not be distorted, if the small picture and low resolution in the case of enlargement, the picture will be blurred. High resolution images I usually can modify and view under PHOTOSHOP, with ACDSEE can also view the specific resolution value.

There are two resolutions for pictures~~

The first is the common online 1600X1200 ~ 1024X768 ~~

The second is known as the print resolution commonly used is 70DPI ~ 300DPI ~~

In fact, the monitor can display the fine degree of 70DPI ~~

So if

So if you're just displaying on a screen, choose something with a higher resolution like 1600x1200.

The larger the resolution, the larger the area of the picture and the larger the file size for a photo of the same size (bitmap). Usually, resolution is expressed as the number of pixels in each direction, such as 640×480, etc.

The more data an image contains, the longer the graphics file will be and the more detail it can show. But larger files also require more computer resources, more memory, more hard disk space, and so on. On the other hand, if the image does not contain enough data (lower graphic resolution), it will look quite rough, especially when the image is scaled up to a larger size for viewing. So during image creation, we must decide on the correct resolution for the final use of the image. The trick here is to first ensure that the image contains enough data for the final output. It should also be the right amount to take up as little of the computer's resources as possible.

Resolution is directly related to the pixels of the image, let's do some math, a picture with a resolution of 640 x 480 pixels, that's 307,200 pixels, which is often referred to as 300,000 pixels, and a picture with a resolution of 1,600 x 1,200, that's 2 million pixels. In this way, we know that the two numbers of the resolution represent the units of the number of points that the picture takes up in length and width. The aspect ratio of a digital image is usually 4:3.

Annotation: Resolution is a parameter used to measure the amount of data within a bitmap image. It is usually expressed as ppi (pixels per inch) and dpi (dots per inch). Ppi and dpi (dots per inch) are often used interchangeably. From a technical point of view, "pixel" (P) only exists in the field of computer display, and "point" (d) only appears in the field of printing or printing, please note that the reader to distinguish.

In general, the higher the resolution, the larger the image, and you can find high-resolution images by arranging them in order of size ~

But high resolution does not equal high quality, and some images are artificially enlarged ~

So seeing is believing in many cases ~
