What is large format?

The lens of a large-format camera is basically different from that of small and medium-sized cameras such as 120 and 135. The lens of small and medium format camera needs high brightness, high resolution and considerable contrast ability, so as to ensure that the camera can avoid vibration as soon as possible in low light environment and ensure the image quality when shooting quickly. But for a large format camera that can shift, tilt and swing, this problem is not the most important, but the lens angle is the key. Because it determines whether the photographer can effectively play the shift function provided by the large-format camera. The larger the lens viewing angle and the larger the image circle, the better the axis shifting characteristics of the large format camera.

Advantages of large format:

1. The 45 loose-leaf film area of the large format camera is 13.5 times that of135 film area; It is 3.7 times the area of 120 film (66). For making large or huge photos, only large negatives can achieve fine particles and true texture.

2. The frame and lens of the large format camera slide along the monorail track or the folding bottom plate, and the telescopic leather cavity can be adjusted to achieve the gathering effect, adjust the corrected perspective, and make the plane distribution clear, showing the characteristics of horizontal and vertical.

3. In the grand shooting of majestic peaks, grasslands, lakes, colorful forests and other scenes, the distance of the theme is clear and natural, which accords with natural perspective and is better than eye perspective.
