How to distinguish the photos taken by the camera from those taken by the mobile phone at once?

The photos taken by mobile phones have made great progress than in the past. With the improvement of the technical level of photosensitive elements and the improvement of built-in algorithms, the purity, clarity and color of photos taken by mobile phones can fully meet the daily social needs of the public. So what's the difference between the photos taken by mobile phones and those taken by cameras? In fact, there is still a big difference. If we carefully observe and distinguish, we can see that there are the following differences between them:

1, noise control level under high sensitivity. No matter how powerful the mobile phone photography function is, its cmos volume is still much smaller than that of the camera, which is a compromise based on the overall volume control of the mobile phone. After the small-size cmos increases the sensitivity, the noise is more than that of the camera, and the details are more delayed. For example, taking pictures at night, ordinary apsc format cameras can turn on high sensitivity to iso 1600, and noise control is also excellent, but the mobile phone is full of noise.

This photo was taken by a camera with iso set to 800. The noise is not obvious, and some dark details are found later. If it is taken with a mobile phone, not only the dark details are not easy to find, but also the noise will affect the overall look and feel of the picture.

2. The picture is distorted. Most mobile phones are designed with wide-angle lenses and fixed focus. For example, the main camera of some mobile phones is equivalent to a full-frame field of vision with a focal length of 28 mm, but due to the small cmos size of mobile phones, it is necessary to make the focal length of the lens very short, and its actual focal length may be only a few millimeters. Such a short-focus lens will make the picture very distorted, and the mobile phone has to rely on the built-in algorithm to correct this distortion, but it is still much larger than the camera distortion. When you take a picture with your mobile phone close to the subject, the distortion effect will be amplified. Especially at the edges, you can sometimes see obvious deformation and stretching.

This picture taken by mobile phone shows that the marginal building has been deformed. Cameras can use lenses with different focal lengths, and the distortion control ability is much stronger than that of mobile phones. For example, taking pictures with a lens of more than 50mm can basically achieve a distortion effect that is imperceptible to the naked eye.

This photo taken with a 100 micron lens has no distortion even at the edge.

3. The depth of field is obviously different. As we all know, the three factors that affect the depth of field, that is, the strength of the blur effect of the picture, are focal length, aperture and shooting distance. The aperture of the mobile phone itself is not small. Many mobile phone lenses have achieved a large aperture of f 1.7, but because the focal length is too short, the shallow depth of field effect is greatly reduced compared with the camera. Mobile phones can only blur the background in a shallow depth of field when shooting close-range scenes similar to macro, and it is difficult for ordinary subjects to shoot natural blur effects.

The photos taken by this mobile phone, f 1.7 aperture, are close to plants, but the background is still relatively clear.

This photo taken by the full-length camera uses the aperture of f2.0 to keep a certain shooting distance, and the shallow depth of field effect of the foreground and background is very obvious.

In fact, whether you take pictures with a mobile phone or a camera, the most important thing is to control the characteristics of the equipment reasonably, make use of its advantages, give full play to its strengths, and shoot a suitable subject, instead of obsessing about the subtle gap in image quality. For example, mobile phones are extremely portable and very suitable for shooting documentary street shots. For ordinary documentary subjects, noise and distortion are not a big problem at all. The large depth of field of mobile phones is more suitable for documentaries. The camera has the characteristics of high tolerance, pure picture and deep scenery, which is obviously more suitable for taking portrait photos than mobile phones. As long as the application equipment is right, any equipment can shoot wonderful works.

There are many ways to distinguish photos taken by mobile phones from those taken by cameras. Let's talk about the difference that can be seen directly by the naked eye first, so as to prevent others from saying the wrong thing when sending you photos. If they are right at once, they will be more professional and professional.

Through these points, we can basically see that the mobile phone is still taken by the camera, and the mobile phone, especially the night scene, is poor, which is caused by congenital deficiency. Even if it is optimized by AI algorithm, it is much worse than the big sensor of the actual camera. In addition, the works taken by mobile phones have a strong sense of smearing. Just zoom in and see how small the particles are.

There is also too much depth of field blur. The blur of mobile phone is based on algorithm optimization, not the real blur of large aperture lens. The authenticity and details are very different, which is also the shortcoming of mobile phone shooting.

Based on these small details, I hope I can help you distinguish them. I hope my answer can help you. Thank you.

Give three photos and enlarge the details. Was it taken by mobile phone or camera (compressed upload)?

Generally, photos taken by mobile phones have bright colors and high saturation.

You can use Meitu to look at the original file of the opened photo. Right-click the menu and click "Picture Information" at the bottom to see whether this picture was taken by a mobile phone or a camera, as well as the specific model, shooting date and focal length.

2. The computer has professional software to open the photos to see the properties. The shooting information inside is very detailed, including camera model, shooting time and so on. , at a glance.

3. The current digital technology is photoelectric conversion, and the core is photosensitive element. The mobile phone may not be as big as the little finger nail and the thumb of the SLR, for example, it is also12 million pixels, so many pixels are divided into two different originals.

4. The bigger the SLR, the more it can suppress strong light purple edge, high sensitivity noise and color reproduction. Of course, the quality of the SLR is good, and the lens is the more important factor.

It's still hard to see on the mobile phone screen, but the difference is obvious on the computer monitor.

In fact, the pixels of mobile phones and SLR are not a concept at all, and the conversion units are different. Some so-called mega-pixel mobile phones, the final image quality may not catch up with the multi-pixel SLR. So interested netizens can popularize science by themselves.

By the way, different storage formats also lead to different final image quality. JPEG format is very different from RAW format, not to mention TIFF format. If you can view the background data, there is a huge difference between mobile phone photos and camera photos.

Just as your photos are limited to browsing and spreading on your mobile phone, there is no need to be more realistic. But if you have other needs, especially to enlarge or even make works, it is recommended to use SLR!

Can you tell which is the mobile phone and which is the SLR?

I want to know right away. I want to enlarge the photo by hand. The worst thing about a mobile phone is to enlarge its size, but the camera will not be so blurred. The obvious difference is here!

Just zoom in on the computer and you'll know.

You can see it by zooming in on the computer. This is because the area of the dry photosensitive chip is different, and the higher the voxel, the more obvious it can be distinguished. If you zoom in to the pixel level, you can see at a glance that the pixel edge of the mobile phone can't be clearer than the camera, and the edge hair is inevitable.
