Home textile photography, powerful impact non-deformation lens

The wide-angle lens itself is characterized by a wide viewing angle, and shooting the same scene can be closer to the object than the standard lens. But the perspective effect of close-range shooting is stronger, which is not the same as lens distortion. For example, shooting a tall building from the ground, a high-quality wide-angle lens will not bend the edge of the building in a straight line, but will widen and narrow the building, which will have a unique visual impact. Harmful deformation of the lens is another matter. For example, harmful pincushion distortion will make the middle part of a straight line bend inward, while barrel distortion will make the middle part of a straight line protrude outward. This is distortion.

To reduce the perspective effect of wide-angle lens, you can only keep the subject away from the camera. For example, in the case of a building, the lower part of the building is 0/0 meter away from the camera/kloc-and the upper part is 0/00 meter away from the camera/kloc-. The ratio of the two distances is 10 times, and the perspective effect must be very strong. If the distance from the lower part of the building to the camera is 200 meters, and the distance from the upper part of the building to the camera is 300 meters, the ratio is only 1.5 times, and the perspective effect is not obvious. However, in this way, the area occupied by buildings will be much smaller.

If you want to take a close-up of a building with the same width from top to bottom, you must use a shift lens.
