Same background! I know nothing about photography. I just look comfortable. I took this with a 300,000-pixel mobile phone four years ago.

I have used SLR for more than ten years and played mobile phone photography for two and a half years. Comparing the image quality of SLR and mobile phone only on the screen of mobile phone, the difference is not obvious. Displaying photos on the computer screen, the difference is clear at a glance. Mobile phones have incomparable convenience to SLR. If it's not a formal job, I don't usually take SLR photos, which is too heavy. Attach a few photos, and netizens can judge the mobile phone SLR by themselves.

I have been taking pictures with a SLR for many years. Although I haven't studied the imaging technology in depth, at least I still have some feelings. It can be said that there is still a big gap between the imaging quality of SLR and mobile phone. It's just that most people don't feel it. There is no doubt that the photo quality of SLR is much better than that of mobile phone. This quality is so good that it can hardly be mentioned in daily photos and some messy pictures on the Internet. Once the requirements for photo quality become higher, the advantages of SLR imaging can be reflected immediately. For example, all kinds of commercial photography, fashion magazines and photos taken by celebrities. In terms of imaging quality, pixel and color reproduction, the integrity of image information, and the space that can be adjusted later, mobile phones and SLR are not comparable. Simply put, the space in the later period of mobile phone photography is extremely small, because the biggest defect of mobile phone photography is that the image data is not real enough, such as the optical transmittance of the lens and the size of cmos, which are the imaging defects of mobile phones for a long time. It is difficult for ordinary people who have not been exposed to SLR to distinguish, but these irreversible flaws add great difficulty to the later photos. So this is also the main advantage of SLR. Photography is a very professional knowledge. People who say that mobile phones are similar to SLR, do you think mobile phones can shoot star blockbusters? Can you take high-quality photos? Which studio do you go to, and the photographer will pay for your photos with his mobile phone? Some reasons are simple, but you don't understand why SLR is good. Saying that a mobile phone is similar to a SLR can put away your ignorance.

I bought a SLR in order to go to Tibet the year before last. On that day, I made an impromptu comparison between SLR and mobile phone (HTC). I'm not good at taking pictures, but the effect is clear at a glance.

Arguing about this is of little significance. Some people can't make a good film with medium format, while others make a good film with lomo camera. Composition, artistic conception and photo theme are the keys to a good photo. SLR and micro-single, mobile phones and disposable cameras are props. The pen in the writer's hand, the scissors in the tailor's hand and the sword in the samurai's hand are wonderful pens and flowers in some people's hands, and fire sticks in others' hands. If you are interested in photography, it will definitely be better to have good tools. If you want to practice your hands, just take a cell phone. If you like the feeling of large aperture, buy a SLR; Take children under the age of 6 out to play, and never bring a SLR or even a micro-single. I'm exhausted.
