With the progress and development of society. Universities began to proliferate in many places. Every year, a steady stream of college students go to the university.

At the same time, with the development of our country's economy and the increasing degree of our country's opening up to the outside world, universities are also opening more majors for students to choose from. There are more things to choose from. Of course, different majors will have different emphases. The equipment required will also vary. The price of the equipment will also vary. Compared with poor students, it is very important to choose a major that costs less. The necessities for professional courses are also different. But some are still the same. Such as photography and forensic medicine. SLR is an indispensable equipment for them. For many people, they don’t know what a SLR is? A SLR is a type of camera. But SLRs are different from ordinary cameras. SLRs have higher pixels than ordinary cameras. The technical content it possesses is much higher than that of ordinary cameras. So this has become a necessity for photography majors. Photography major is an art major. When arranging a photo, the light elements in the photo are very important, and a SLR can meet this need very well. At the same time, due to the relatively large value of SLR, the price will be relatively high, so people with average family backgrounds will not choose this major. Another major is forensic medicine. Forensic doctors also need to take photography when conducting legal research. For example, when performing anatomy, some body parts will be photographed and recorded. Of course, there are great requirements for pixels when recording. Because some accidents occurred and then were dissected, this would be of great significance for research and evidence collection. Therefore, a SLR is a necessary item in the photography and forensic professions. Of course, these two majors are not the only ones that need a SLR. There are also other majors that require photography of works.
