What lens focal length most closely resembles the perspective of …
2013年2月13日 · \$\begingroup\$ Perspective has nothing at all to do with focal length, magnification, or FoV. Perspective is determined by the position of the lens and the position of the objects whose reflection (or emission) of light is projected through that lens. It doesn't matter if the lens is a camera lens or a human cornea. \$\endgroup\$ –
What is the difference between perspective distortion and barrel …
2016年12月22日 · Perspective is determined by the position of the camera relative to the scene. When a camera position produces a perspective that makes an object or scene look different than we might expect it to look we call that perspective distortion. All of the other distortions listed are a result of the way lenses bend light as the light passes through them.

2023年10月28日 · \$\begingroup\$ Or perhaps if I gave another example, if we had a large plain room like the one above with the side walls parallel to the camera, it would be a one point perspective. However, now lets place a giant cube (practically filling the room) into the center of that room, obliquely to the camera, with one of its edges facing the camera.
relationship between focal length, perspective projection and …
2020年2月17日 · Perspective is the spatial relationship between a camera and the things the camera is photographing. If two objects of the same size are in the scene and one is much closer to the camera than the other the closer object will appear to …
perspective - Is it possible to calculate the distance to an object ...
2015年12月18日 · For example, an Ames room uses forced perspective to trick your brain into thinking that a person walking around is growing and shrinking rather than moving closer or farther away. A photograph is a two-dimensional projection of a three-dimensional scene, and a lot of information, including size and distance, is lost in creating that image.
focal length - How does crop factor affect perspective?
2018年4月4日 · Perspective is dependent only upon shooting distance - both the distance from the camera to the subject and the distance from the camera to the foreground/background, and the ratios between them all. If you shoot from the same distance with two different sensor sizes or different focal lengths and crop the wider shot to match the narrower angle ...
What does it really mean that telephoto lenses "flatten" scenes?
2011年12月19日 · On the other hand, consider the same shot taken with a telephoto lens (same framing / composition). In this case, you are standing further away, so the camera-to-nose : camera-to-ears distance is around 1:1. This is why telephoto shots …
Are professional cameras better when it comes to knowing how …
2024年6月11日 · It's not the cameras per se. It's that a bigger sensor is used with longer lenses. Lenses with longer physical focal lengths and bigger working distances in studios that let you avoid perspective distortion (and lens barrel distortion) vs. a smartphone camera. Perspective distortion happens with very short lenses used in very close to the subject.
perspective - What is ideal distance to subject for head and …
Perspective is a matter of distance and has an effect on facial features and the observed three-dimensional feeling in a two-dimensional photograph. Proper lighting is a big part of this, but that's another question. First I'd choose the distance between camera and subject.

2015年9月8日 · close-up photos will enlarge nearer facial features such as nose and forehead, as a short camera distance will magnify the discrepancy in camera distance between different features (as opposed to far-away images in which the distance variation between features is 'diluted' due to the long camera distance)
