35mm胶片的标头是50mm,用来照人像的话是照全身还是半身?离被照的人该多远?底片
上人像应该占多少比例?
简化一下问题:拍人像离多远拍,用标头。
或者在具体一点,选定被摄物和限定拍摄距离后,如何选镜头

see wiki: http://en.wikipedia.org/wiki/Normal_lens
In photography and cinematography a normal lens is a lens that reproduces
perspective that generally looks "natural" to a human observer under
normal viewing conditions, as compared with lenses with longer or shorter
focal lengths which produce an expanded or contracted field-of-view.
Lenses of shorter focal length are called wide-angle lenses, while longer
focal length lenses are referred to as long focus lenses[1] (with the
most common of that type being the telephoto lenses).
A lens with a focal length about equal to the diagonal size of the film
or sensor format is known as a normal lens; its angle of view is similar
to the angle subtended by a large-enough print viewed at a typical
viewing distance equal to the print diagonal;[2] this angle of view is
about 53° diagonally.

ography Tip—How to Choose a Portrait Lens
portrait_lensWhat makes digital photography so attractive as a hobby is that
you can find a photographic form you specifically like, such as landscape,
wildlife, weather, close-up and portrait. Each requires slightly different
equipment and skills to take the very best images. If portrait photography
has captured your attention, then, quite possibly, the most important
equipment consideration is the lens you use. This PhotographyTalk.com
article presents important information and a number of tips to help you
choose the right portrait lens.
Understanding point of view.
A camera lens does not affect your point of view, or perspective. Only your
position has a direct correlation with perspective. Short and long lenses
only affect the frame of your image, giving you a narrower or wider view.
You may have to change your distance to the subject to frame him or her
correctly with lenses of different focal length; but again the perspective
remains the same. For example, a 50mm lens is not the right lens for a tight
framing of your subject’s head. You’d have to be so close that
distortions would occur, making for a poor portrait that is probably also
unflattering.
The 15-Foot Rule.
Research repeatedly shows that when your brain creates an image of the
facial features of the person in front of you, it does so from approximately
15 feet. If you stood very close to someone’s face, then your brain would
show his or her face in the proportions of being 15 feet from the subject.
You wouldn’t see any distortions, but if you placed the camera lens that
close to the person, then it would register those distortions. This means
that the best distance for digital portrait photos is 15 feet.
This “rule,” like many, is actually a guideline. It’s your artistic eye
that will tell you the correct distance for digital portrait photos of
different people. Some will look better closer; others require that you
widen the distance.
The 15-Foot Rule has been used to create the following chart, which shows
the size of a subject that would fill the frame comfortably with different
lenses from a distance of 15 feet.
screen shot 2011-05-19 at 11.15.06 am
Your choice of view.
* Choosing the right portrait lens is also a function of how will frame
your subject.
* Complete view of the subject standing: 50–70mm lens.
* Complete view of the subject seated: 70–105mm.
* Head and shoulders: 200mm–300mm lens, so you can stand 15 feet from
your subject.
Background affects your choice.
For most digital portrait photos, the background should not be in focus, and
essentially disappear, as the reach of the light decreases behind your
subject. To achieve that background effect, you should shoot with a long
telephoto lens with a large aperture, or lens opening: 300mm f/2.8 or f/2.
Another consideration is bokeh. This is an unusual attribute of lenses that
records more background details than your eye may see. Even when you’ve
blurred the background, it can be a distraction when a lens generates too
much bokeh.
The correct portrait lenses.
Consider the following lenses as good choices for shooting portraits (as of
the time of the writing of this PhotographyTalk.com article).
* Nikon 135mm f/2 DC, or Defocus Control: With that feature, you can
optimize the Bokeh effect to create an unobtrusive background for your
portraits.
* Nikon 105mm f/2DC: This lens is slightly smaller and has a smaller
price tag.
* 80–400mm for headshots in a studio setting.
* A 300mm f/4 lenses costs much less than an f/2.8 lens of the same
focal length, without much difference in how well the background disappears.
* The 18–55mm zoom that was included with your camera will do a good
job, at 55mm.
* Try a 70–300mm zoom if you are willing to spend some money for more
versatility.

Lz,我觉得你跑偏了。
这东西技术一定就够了,原理不用弄那么清楚,除非是上论坛跟人当不要钱的老师。
拿那个18-135照几张先看看,尤其在35和50端(实际焦距,不是等效),看看就知道了。
你也没太多选择。不是50 1.8就是35 f2。后者新的300,有这个钱直接50 1.4了
技术上的东西不能纸上谈兵机械教条。你最后要的是清晰好看的片。难不成你买了50毫米,以后只能要么照全
身,要么照半身,照了10张半身再跑去照全身,镜头就会爆炸么?

First, the portrait lens is not just about focal length. It is about
perspective too.
You will commonly be taking a traditional portrait that includes head and
shoulders, and you want it to look general to the viewers. That means you
don't want facial parts to look distorted or out of proportion.
Normal length from your subject to perform a general perspective is about 10
feet. You can perform this with a lens that is between 75mm and 150mm. If
your Camera is a "crop" sensor, you can use less focal length because the
Camera will capture Photos as if it were a longer lens. An example is a
Canon Rebel with a 50mm lens will act like a full frame Camera with an 80mm
lens, taking into notice the 1.6x sensor.
You can get the same image with a 22mm lens as you can from an 85mm lens if
you are closer to the subject. However, there is a very real possibility of
having a distortion of facial parts because you will be so close to your
subject.
For that reason, the best Canon portrait lens is at least 85mm.
On the other hand, you don't indubitably want to use a telePhoto lens that
is, say, 400mm, plainly because you would have to be too far away. Yes, you
could get a great shot than the 22mm example, but the length from the
subject being somewhere around 30 ft is not optimal for communicating with
your subject.
That's why the best Canon portrait lens selection would also be 150mm or
less at the long end.
