Camera formats refer to the different sizes and types of film or digital sensors used in photography. Common formats include 35mm, medium format, and large format. Each format affects the image quality, depth of field, and overall aesthetic of the photographs. Larger formats typically capture more detail and produce higher-quality images, while smaller formats are often more portable and easier to use. Digital camera formats can also vary, with full-frame and crop sensor being popular choices among photographers. Full-frame sensors are equivalent in size to 35mm film, while crop sensors are smaller, resulting in a narrower field of view. Understanding these formats helps photographers choose the right equipment for their needs.
