-held conditions. For example, if the equivalent focal length of the Canon a75 lens is 35mm-105mm, the shutter speed should be at least 1/40 s at the wide angle side to ensure that the photos are clearer, at the focal point, the shutter speed should reach 1/125 seconds. If the light conditions on the scene cannot meet this requirement, it is not that simple to take a clear photo. As you can imagine, anti-shake technology is more necessary for those 10

. However, photographers must understand the visual relationships, proportions, depth, and effects of different focal lengths on the subjects. Generally, a wide-angle lens expands the space, while a long lens compresses the space. However, this is a misleading generalization. Photographers such as artwolff, gorun rorwell, Jim bleden Berger, Yang yunth, and Neil benvi used 35mm cameras to produce impressive photos. For landscape photography, selecting

different focal lengths. This is an optical fact. Believe it? Then a specific test is performed with one 35mm shot and one 200mm shot. First, use a long camera to photograph a friend standing next to a long fence filled with flowers. Then she switched to the wide-angle camera and approached the shooting, so that she was as big as the previous image in the viewfinder. Observe these slides with a 10x magnifier and you will find that the acceptable clea

In terms of image quality, since the resolution of high definition is basically four times that of traditional analog TVs, the image definition and color restoration are far better than those of traditional TVs. At, the wide screen display also gives you a wider visual experience. From the au

There are two internationally recognized high-definition standards: the vertical resolution of videos exceeds P or I, and the ratio of video width to height is 16: 9.
