principle of this virtual, but also need to grasp the lens focal length and shooting distance relationship.2. Grasp the focal length and shooting distance of portrait photographyActual measurement of the shooting distance of a representative 5 kinds of compositionShooting distance※ 1: Less than the most recent shooting distance to use the lens when shooting.※ 2: Shooting with 35mm full-frame camera. Brackets indicate the lens focal length required to shoot with the APS-C spec camera under the s

lacks focus. 　　 A wide-angle lens can take a large range of photos. (Nikon D700 f8@16mm) (iii) Long Gio can rule out the elements Long Gio shot out of the narrow view, the photos will not contain a wide range of scenery, excluding the elements, so that readers can focus on the same thing (the protagonist), suitable for shooting close-up photos, or when the background is very messy to use. 　　 Use the 200mm telephoto to exclude unwante

than that of Grade D steel, it also has the same cold forming function as Grade D steel, because the normalization process is less time, the production cost is much lower than Grade D steel, which is cost-effective for users. The photo shows that the steel sheet has outstanding plasticity at normal temperature and is suitable for Cold Forming and other cold forming processes. It can be seen that the brittle transition temperature of kv2 of the selected D-grade steel plate is about-25 ℃ (exactly

prepare to shoot. Before filming, you should have your camera equipment: cameras, wide-angle lenses, tripod, shutter line (not required for individual models). This is enough, we say, shoot the stars, in fact, do not need too much equipment or accessories. The parameters taken are different depending on your equipment. I recommend a few more commonly used parameters for your reference: ISO3200 F2.8 16MM 20S, ISO3200 F4

Lock types:1. locks: they are divided into copper locks, iron locks, and password locks. Their main specifications include 15, 20, 25, 30, 40, 50, 60,

the advantages and disadvantages of the motor from the side. Generally, the smaller the capacitance value of the household fan, the smaller the starting current of the motor, the more energy-saving the motor, the more stable the performance of the motor. In addition, the higher the rated voltage value, the stronger the voltage impact resistance of the capacitor, and the more stable the motor performance. (3) view the thickness of motor silicon steel sheet: It is difficult to test the advantag

face must be prepared before splicing. The coating layer is peeled off with a special wire-stripping clamp, and then wiped several times on the bare fiber with alcohol-stained Cleaning Cotton. The intensity should be moderate, and then the optical fiber is cut with a precision optical fiber cutter to 0.25 (outer coating) optical fiber, cut length is 8mm-16mm, for 0.9mm (outer coating) optical fiber, cut length is only

Know "wide-angle lens" and "super Wide-angle lens" In general, the 24mm is already a wide-angle lens (Aps-c is 18mm) under the full picture allows you to incorporate a lot of landscape content into the photo, but there is another, more wide-angle lens that can reach 16mm (full width) or 10mm (APS-C), and these lenses are "super wide-angle" ( ultra-wide)! For landscape photographers, the wide-angle lens is useful, but the more useful is the "super wi

stripping clamp, again with alcohol cleaning cotton in bare fiber wipe several times, force to moderate, and then use precision fiber cutter cutting fiber, 0.25mm (external coating) fiber, cutting length for 8mm-16mm, 0.9mm (outer coating) fiber, cutting length can only be 16mm. ⑤ Place the fiber. Put the fiber in the V-groove of the welding machine, carefully press on the fiber plate and fiber clamp, acc

Business Scope: two prime regions in China's Yangtze River Delta and Pearl River Delta, involving Marketing Planning, film, TV series, TV commercials, corporate videos, 3D animations, and other large-scale film and TV production, is one of China's most powerful and influential professional film and television shooting companies. Excellent team:Based on the current market situation in China, the company focuses on the future-looking international business philosophy and brings together

late synthesis is essential. Do the movies that need special effects be made from green behind the scenes? But a lot of beginners have always had a misunderstanding, that the late to learn is a photographer master. I am in the network class teaching students repeatedly stressed the importance of the early stage, even if you take the composition background, light perspective always and the background on it (this is the key to the synthesis of natural or not), the model's eye posture is the later

Wide-angle worse, worse off than 24mm is a wide-angle focal segment, the angle of view is 84 degrees, although there is no 16mm and 20mm as a broader cover, but the general indoor and outdoor are enough to cope with, than 35mm wide, shooting a three or a tour of the

-tube unit A micro-tube unit is composed of a silicon core layer added to the inner wall of HDPE material. Generally, the inner wall with a diameter of more than 5mm has a flow channel, the inner wall of the microtube diameter below 5mm does not have a flow channel. At present, the external diameter of the micro-tube generally ranges from 3mm to 16mm. The number of fiber cores that can be accommodated in one microtube ranges from 1 core to 288 cores o

used for handheld shooting night. White balance: Used to restore the color of the scene under different scenes. Generally automatic. 7. Common Concept and specification introduction Safe shutter: Value equals (equivalent) the inverse of the focal length, and the shutter speed is greater than this value when hand-held easily count. Focal length and focus: the focal length is the distance from the center of the lens to the focal point, changing the focal length to change the curvature of the lens

the 1.5x range in the FF image ..Although the diagram and the angle of view are similar to the FF + 35mm focal segment image, the depth of field of depth must be relatively deep when shooting with a wide lens...Reverse thinking... if FF is shooting with a 35mm 2.8 aperture... APS-c, which of the following lenses can be used? ? Around 24mm 1.4 aperture... suppose 24g is used to replace... so you can imagine that at the same shooting distance... APS-C with 24 Open 1.4 aperture under the same diag
