2. 70 mm film

3. Both 35 and 70 mm film

4. Both 16 and 35 mm film

The correct answer is: Both 35 and 70 mm film

The film used in professional-type projectors commonly includes both 35 mm and 70 mm film formats. 35 mm film is the standard format for most commercial films and has been widely used in the film industry for decades. It provides a good balance of image quality and cost-effectiveness, making it the preferred choice for many filmmakers. On the other hand, 70 mm film is utilized for high-resolution projects due to its larger size, which allows for greater detail and image clarity. It is often employed for epic films and those that aim to deliver a superior viewing experience, especially in large theaters. By acknowledging that both formats can be employed in professional projectors, the response highlights the versatility of film projection technology and how it caters to different artistic and technical requirements.
