The difference between a mobile phone and a SLR camera.

The difference between mobile phones and SLR photos 1 First, let's talk about the principle of digital photos:

When the shutter is pressed, the lens focuses the light on the photosensitive device CCD or CMOS, and its function is to convert the light signal into an electrical signal. In this way, we can get the electronic image corresponding to the shooting scene, and then use DC (Analog-to-Digital Converter) and MPU (Microprocessor) to compress the digital signal and convert it into a specific image format, such as JPEG format. Finally, the image file is stored in the built-in memory.

Therefore, the core component of digital photography is the photosensitive element. So what is the relationship between pixels and photosensitive area? Look at the picture below:

What? It's too complicated to understand. ...

Ok, then the next picture can directly explain the size ratio of the photosensitive element ~

This is the actual proportion of the size of the photosensitive element. Did Quan Huafu SLR get higher in an instant?

The size difference of photosensitive element is so much! Then why is the difference between the photos taken by mobile phones and those taken by SLR not so big?

Because the pictures taken by our mobile phones are mainly used for self-media, the requirements for information are not very high. The SLR is different, it is more suitable for post-production and amplification. Therefore, in the highly compressed picture mode of WeChat, the advantages of SLR are not obvious.

Let me show you the photos I measured.

In order to enrich the background, I put some money in it. The first one is a SLR photo. Due to the limitation of the lens, the aperture is 4, but the background blur is already obvious. The second photo was taken by a dual camera phone. Neither picture has a late stage.

Through comparison, it is found that there is no later period, and the photos taken by mobile phones are more beautiful in color and higher in saturation, which is very suitable for making friends after cutting. SLR photography, on the other hand, keeps all the gray information of the photos, which makes the blur natural and leaves a lot of room for post-processing.

Having said so much, I have no intention of raising or belittling at all. Mobile phone shooting emphasizes composition, and as long as it is handled properly, it can shoot a large film; SLR shooting should emphasize the depth of field, so that the photos can be more layered. The mobile phone is easy to carry and light in weight.

There is no best shooting equipment, only the one that suits you best, whether it is a camera or a mobile phone, can record the wonderful things in life.

The difference between mobile phone and SLR photography is 2 1, and I prefer the feeling of shooting with a camera.

As a photography enthusiast, photography is often mainly a feeling. Shooting with a camera has become a habit. Just like smoking and drinking, I am used to shooting with a camera, and I always feel that shooting with a camera is the fun of photography.

2. I prefer the shooting effect of SLR camera.

There are always people who say that the effect of mobile phones can be comparable to that of SLR cameras, but I don't think so.

3. The quality of the photos taken by the camera is definitely better than that of the mobile phone, no matter from the photosensitive element or the lens structure. I also often take photos with my mobile phone, and the photos I take are almost invisible on my mobile phone. If I watch it on the computer, the oil content and sharpness of the color are not as good as those taken by the camera.

4. The larger the pixel of the mobile phone, the higher the picture quality.

Although the pixel of the mobile phone is very high now, it's just that the file has increased. Just like a picture, the size of the picture is enlarged in PS, and it seems that the pixels have increased a lot, but the picture is still the original picture, and its original information has not improved.

The lens of mobile phone is very different from that of camera.

The mobile phone lens adopts electronic zoom, which is equivalent to a magnifying glass. The camera lens adopts optical zoom, and the imaging principle is different. Of course, the photos taken are definitely better.

6. In a word, although the mobile phone has the advantage of being easy to carry, in terms of the effect and image quality of taking pictures, it is definitely a SLR camera. Undoubtedly, it is better for SLR cameras.
