I've used DV in my company before, but it's only been a few months, from scratch. Tell me something you know.
DV camera
I used Panasonic AD4 10. In my opinion, when I choose DV.
A: The larger CCD size is more important, and the shooting quality is better, which is more favorable for dealing with slightly dark scenes. If you don't take pictures with DV, then the pixel value is enough (AD4 10 is a professional machine, and the film you shoot meets the requirements of broadcast level, with 80W pixels).
B. The optical zoom of the lens is more useful, but the digital zoom of the home computer is basically useless, because you need a stable character when shooting. The machine I use only has optical zoom 16X, but I don't use 14X at all, because the lens shake can't be kept within the allowable range when I use 14X, so I use it on a tripod when I use 14X or more. Shoulder machine, not to mention hand-held home machine.
C. It would be better if the camera has these functions that can be adjusted manually: shutter speed, color temperature (sunlight and lighting of home computer), aperture and focus. There must be a balance between black and white.
Shooting aspect
Answer: When shooting, the teacher told me that the most important thing is to keep the word steady, which is the basic skill. At that time, I shot at the object twice a day for half an hour under the zoom of 16X. Try to use a fixed-focus lens in actual shooting, and use less push-pull jitter. When using a push-pull lens, try to get close to the subject, aim the maximum multiple of the focal length at the subject first, and then push and pull after focusing clearly, so as to ensure that everything is clear. Before entering the next step, push and pull and shake the subject for 3- 10 seconds.
B. Before shooting:
1。 Select the appropriate filter (color temperature)
2。 Adjust the black-and-white balance (aim the lens at white objects, such as walls and white paper, and fill the whole picture. Press the black and white balance key, and the camera will automatically adjust). If it's too late to switch scenes, set it to automatic.
3。 The shutter and aperture are well set. If the scene keeps changing, put it in the automatic file. If it is fixed in the scene, set a fixed value and don't change it. Putting it in the automatic file will cause the brightness of the picture to change when you push and pull the lens.
C. The recording quality at the beginning and end of the tape is not good. You can put a color bar of about 30S before recording the official content. Don't have the back of your head in your composition (the teacher said it was cold several times when shooting).
