How to set the camera resolution?

How to set the resolution/pixel/size of a digital camera? Many friends often encounter being told "pixels are too low?" Will it be blurred when washed out "or" will it be cut off if the proportion is wrong "? After professional explanation? You can basically understand why. But our real purpose is to make the photos clear and effective? Don't cut or anything? So you need to check your camera resolution settings. All the following are explained in vernacular? Easier to understand It's not worth pondering from the perspective of technical terms ~ but the basic principle is correct? You can rest assured. ? First of all, understand a few questions 1, pixel? Is this picture made up of dots? Called pixels? The number of pixels on the long side multiplied by the number of pixels on the short side is the number of pixels in the whole picture. For example, 1600* 1200 pixel is the long side of 1600 pixel? Short side 1200 pixel? 1600 *1200 =1920000 =1920000 ≈ 2 million pixels. ? Generally speaking? The higher the pixel, the better the definition? Just more pixels? The finer every detail of the picture? The clearer the reflection. Instead, the pixels are low? Less pixels? Every detail is rough? Do you feel like a mosaic? Just don't know. ? 2. Resolution? dpi=dot？ per？ Inch That is, the number of pixels per inch. Note that the unit is per inch? 1 inch =2.54 cm? . More pixels per inch means clearer. ? General photo resolution is 72dpi? The monitor is 72dpi? And if the developed photos are clear in your hands, they are usually pressed at 300dpi? So there will be a situation that "it is very clear on the computer, but it may not be clear when it is washed out." " ?

The relationship between pixels and resolution is similar to the relationship between distance and speed. ? 3. "M" in the camera resolution setting? Some cameras have resolution settings similar to "1600* 1200 2M"? Note that the "m" here is not the "mega" of the file size? Meaning "megapixels"? That is, "The current setting is 2 million pixels? The specific pixels are 1600 and 1200 ". ? How many megabytes did the photo take? It depends on the actual situation? Rich pictures? More information? And then the file is big? On the contrary, it is small. Shooting a flower must be bigger than shooting a blank sheet of paper? Under the same pixel settings, of course. ? Understand the above basic problems. The following is easy to understand ~? How many choices are there for camera resolution? Different brands and even different models of the same brand are different. Give a simple example? See the figure below.

There are generally three grades: l, m and s? Some cameras are not as big as this subdivision. Large size? Medium? In the middle , small? Small? . ? Generally, s is suitable for computer browsing or uploading space sharing? If developed, it may not be very good, and it is not suitable for developing ordinary size photos. Different cameras? If there is a camera S corresponding to 1024*768, is the pixel low? On the other hand, it's okay to develop the normal size photos of S's 2048* 1360 in the above picture? . M file is suitable for developing slightly larger photos? About 7- 10 inch l is suitable for developing larger-sized photos? Like zooming in or attending a photo exhibition? General 12-20 inches? . ? How many choices are there in the same class? See the box above? "4:3? 4:3 "in 2816 * 212 means that 2816 * 212 is 4:3? That is 2816 ÷ 2112 = 4? 3? Some cameras don't give this ratio? Do you need to do the math yourself? . And then the same m file? The pixel difference is not very big? What's the use of just different proportions? Is the framing different? It also means that the sizes suitable for printing are different. What if the 6-inch photo is 3:2? What if it's set to 4:3? 28 16*2 1 12? 6-inch photos will be cut? Part of the picture is full, which affects the overall beauty? You can also leave it blank? It may also affect the appearance. So we have to choose the right pixel according to the size we want to wash. ? Summary? Set the camera resolution? Look at the use first? If the memory card allows, the bigger the better. If you want to develop in the future? See if there are enough pixels? Second, see if the ratio is appropriate. ? Some cameras don't have that many choices? You can only choose something closer. ? The above is aimed at ordinary digital cameras? Card machine SLR is not applicable? Because the SLR configuration is high? Is the resolution reference 150dpi? And the common SLR is 3:2 ratio? There is no other proportion choice. ?
