What is the difference between a digital SLR camera and a film SLR camera?

Many film friends who have used film SLR cameras know that the film camera uses silver salt film photosensitive material, which is what we usually call film. When shooting, the film camera directly stores the image on the film, which can only be used once and the number of films is limited. According to different specifications, the number of films that can be shot by a single film is 36, 24 and 12 respectively.

A digital SLR camera uses a memory card. When shooting, digital cameras store images in digital format on reusable memory cards or other storage media. The storage media have different capacities and shooting formats, and the number of photos stored on the memory cards is also different. According to different camera models, the memory cards used are mostly CF cards, SD cards and XD cards, and individual camera factories need to use their own specific memory cards.

Except for the difference of storage media, film SLR cameras basically need to develop the photos they take before they can see the shooting effect. The LCD color LCD screen installed on the back of the digital SLR camera can easily play back the photos just taken, and the photographer can know the shooting effect in order to adjust the shooting parameters in time.
