How does Canon 5D Mark II prevent the deformation of objects in commodity photography?

The method of Canon 5D Mark II to prevent the deformation of the subject is as follows: The state shooting of the lens uses both offset and tilt. Deviation is used to prevent the wooden box and the wine bottle from deforming, while the inclination angle enables the wine bottle in the wooden box and the wine bottle in the foreground to focus. Even under the aperture of F 1 1, all parts can be well focused. Shooting data camera: Canon 5D Mark II/lens: TS-E 90mm f/2.8/ aperture priority automatic exposure (F 1 1, 1/4s) /ISO 100/ white balance: automatic/exposure compensation:-/kloc-. Because the ordinary lens has no function of offset and tilt, both the wooden box and the wine bottle are tilted outward. Although the deformation of the wooden box and the wine bottle can be avoided by reducing the shooting angle, the thickness and open state of the wooden box can not be shown at the same time. Shooting data camera: Canon 5D Mark II/lens: EF 24- 105mm f/4 lisum/ aperture priority automatic exposure (f 1, 1/4s) /ISO 100/ white balance: automatic/exposure. 2: tilt angle1focus. Start real-time display shooting when shooting is needed. Clever use of grid line display and enlarged display functions can make offset and tilt operation easier. 2. Use offset to adjust the deformation of goods. First, put the camera as close to and higher than the wooden box as possible, and tilt the camera slightly downward. Shift downward to ensure that the goods are not deformed. At this time, try to use a lens with a long focal length, which can better avoid deformation. Therefore, TS-E 90mm f/2.8 is very suitable for commodity photography. 3. After adjusting the product shape by tilting the focal plane, you can adjust the focal plane by rotating the tilting knob. Adjust the legend so that the bottle in front of you and the bottle in the wooden box are in focus at the same time. By making full use of the effects of tilt and offset, we can take two wine bottles as the main objects at the same time. 4. Confirm the focus at the edge, release the shutter, press the preview button of depth of field, and confirm the real-time display of the shooting picture through the LCD. Check the focus range (depth of field) while reducing the aperture. Finally, the aperture value of the legend is F 1 1, and the edge of the wooden box is also in focus. The aperture value of F 1 1 cannot be focused on the wooden box at the same time under the lens of EF 24- 105mm f/4L, so it is impossible to use offset and inclined USM. Use tilt and offset to further improve photo quality, commodity photography and offset bull; There is a close relationship between inclination angles. In order to better display the goods, we must faithfully restore the goods. It is very important to make the product clear and image, so that the whole product is in focus. In practical application, offset and inclination are often used together, and the key point is to make effective use of them according to the shape and position of the subject. First, stand in front of the subject and observe its shape carefully. Think about where to use offset and inclination, and then follow the steps. After you are familiar with the shift lens, the operation sequence and steps of offset and tilt angle will change, but as long as the final imaging effect is good, you don't have to care about these. Master your best offset and tilt shooting steps and challenge more difficult shooting. Attention should be paid to avoid the interaction between the operation knob and translation/tilt. There are various knobs on the axis shift lens to operate and lock the offset and tilt angle. However, due to the different shapes of the pan-tilt used, it is likely to encounter various knobs, which will hinder the adjustment of offset and inclination. So there should be enough space under the lens. At this time, you can choose to use the TS-E lens tripod adapter or the battery box and handle for the axis-shifting lens. Real-time display shooting is often used when using shift lens, so it is quite convenient to put two special batteries in the battery box and handle.
