To the photographic enthusiasts for detailed analysis to share the Canon 5DMarkII camera compensation for building deformation photography techniques.
Skill Sharing:
The state of the lens
By using a moving axis lens with an offset function, you get the same effect as shooting from a high place. So you can make the shape of high-rise buildings look not deformed. Lens effect at a glance.
Shooting data
Camera: EOS 5D Mark ii/Lens: ts-e 17mm f/4l/Manual Exposure (f8,1/250 sec)/iso 100/white balance: Automatic
Use normal lenses to shoot under the same conditions
The state of the lens
Because it is shooting from the bottom up, you have to tilt the camera itself, otherwise you can't shoot. So the building had a significant deformation. Especially at a very close distance, it is impossible to use a wide-angle lens to photograph a building that looks like a vertical.
Shooting data
Camera: EOS 5D Mark ii/Lens: EF 16-35mm f/2.8l II usm/aperture Priority Auto Exposure (f8,1/200 sec)/iso 100/white balance: Automatic
Shooting Essentials
1: Be sure to keep the camera vertical before shooting
Essentials 2: If the building's roof is slightly thinner, it will increase the stability of the picture.
1. Replacement of focusing screen
The building is usually carried out under intense light conditions, so the weather is good and the filming environment is very bright. So sometimes using an optical viewfinder is more convenient than using a real-time display shot with a rear LCD monitor. In order to more effectively grasp the outline of the building or the degree of tilt from the optical viewfinder, can be used to replace the focusing screen of the model, the prior replacement with the grid line of mesh line precision scrub for focusing screen shooting will be more convenient.
2. Before the offset metering, the camera set to manual exposure mode
No matter which kind of moving axis lens can use aperture priority automatic exposure mode and so on to carry on the automatic metering, then shoots. However, if the larger tilt or offset operation, because the lens movement is relatively large, will cause the metering is not very stable. So before the dip and offset, you can use the aperture first automatic exposure mode for metering, and then in manual exposure mode set the camera to calculate the aperture and shutter speed, and then make the necessary fine-tuning then shoot, so that the final photo brightness will be more stable.
3. Use offset compensation the lower width of the building is narrow
First you have to make sure that the camera is facing the building where the object is taken. Then rotate the shift knob and shift the lens upwards. compensate for the widening and narrowing of the shooting of high-rise buildings. The grid line on the focus screen can be used to observe the shape change of the building and to compensate the operation carefully.
4. Carefully confirm the coke situation, release the shutter
After compensating for the shape of the building, focus carefully and then take the shot. Especially around the screen. Due to the visual field of the optical viewfinder may not be fully observed, so you should carefully confirm that there are no extra objects are taken into the screen.
Using the offset function of the axis-shift lens, you can get the same effect as shooting from a high place
In the case of shooting high-rise buildings, the lower width is caused by the problem of shooting angle. When you use the camera to look up, the top of the building narrows because of the sense of perspective. To avoid this, just put the camera right on the building and keep the camera perpendicular. Therefore, in theory, even if the use of ordinary lenses to shoot high-rise buildings, as long as the camera in half the height of the building at the location of shooting, you can avoid the occurrence of deformation. But in reality it is almost impossible. The offset function of the moving axis lens can achieve the same effect as the position of the camera. Perhaps the lens offset is only about 10 millimeters, but because the optical axis has a large offset, so this little bit of movement can have a great effect. There is also a large ts-e 17mm f/4l, so the offset will also increase, the most suitable for shooting high-rise buildings. Even if you take a picture of a building that needs looking up from the sidewalk, it can be as straight as an example.
Small Tips
Use the shutter line to capture the surrounding condition
When you use the shutter line at the scene of the night, you can not shoot with the camera so that you can accurately grasp the surrounding condition, and you can find the pedestrian on the sidewalk and the bicycle crossing suddenly, which is safer when shooting. Also, you can release the shutter without touching the camera directly, so you can avoid accidentally shifting the lens or changing the angle of the camera. To use the moving axis lens for rigorous filming, you can say that the shutter line is a necessary tool.
Well, the above information is small set to all the photography enthusiasts brought to the detailed Canon 5DMarkII camera compensation for the deformation of the building photography techniques to share the whole content, you see the photographers here, small knitting believe you now that is very clear the shooting skills, Then the friends are going to follow the small part of the techniques brought by themselves to take a look at the effect of the film.
