In my recent shoot I used two film cameras, a Canon EOS RT and a Canon EOS 5.

With the 5 you can select a focus point but to do this for every single shot would be too time consuming. I may try disabling all the focus points except for the central one next time. I like the RT because of the uninterrupted view of the subject it gives you, an advantage when using flash. An EOS 1N RS would be better though.

You should just ask a beauty photographer what to when, in describing technique, you're fumbling in the dark and no, rushing to the internet to learn about beauty photography is not really learning about beauty photography, but it's your pose when you're fumbling in the dark. Your summary of a focus puller is better applied to your own camera misadventures. Model directs you to click "can't find the button" you say. . .

A beauty photographer, wow. I've heard of glamour photography, figure photography, nude photography and art nude photography. If you mean a commercial portrait photographer, I don't regard that type of work as very challenging or very interesting.

There are many things in this world that you have not heard of.

And probably for the best you not have interest or attempt either Beauty or Commercial Portrait (two different things), lest you starve to death.

Both (related) fields require actual skill and training, not just the ability to work a search engine.

This is possibly the most absurd remark you have made yet.  You don't regard portrait photography as very challenging or interesting? Have you ever looked at the work of Karsh? Or my late friend Arnold Newman to name just two? You don't see in their work amazing challenges met with skill and artistry? Do you feel that you could do as well? You may not find portraiture personally interesting, and looking at your page I can see you don't do it, and that is fine. All genres don't have to interest everyone. But to fail to see the challenges involved suggests that you have little or no knowledge of the subject. That being the case, it might be wise not to makes comments about the art form.

Commercial portrait photography usually involves headshots. Any idiot can do headshots. Well maybe that's a slight exaggeration but full length pictures are more demanding, especially in a small space if you want to have even lighting of the figure.

I have some gear for portrait photography, umbrellas and snoots and softboxes. I quite often pick up things which I don't use.

Karsh is one name I'm familiar with. Portrait photography seems to follow fashions, a style becomes popular for a while and then is overtaken by something else.

1. Why do you think “Even lighting” is desirable to capture the human form? 

2. What you own has nothing to do with ability to use it.

So you think ".. Any idiot can do headshots" may be an exaggeration? How transparently disingenuous. If you DID believe it was an exaggeration, a NORMAL person would have edited the offending phrase out. You left it in - WHY? Is it because you think your stream of consciousness is somehow valuable for the world to know, or that you didn't really want to disavow it?

By even lighting, I mean an equal distribution of light over the whole figure, this can be quite difficult to achieve in a standing pose with artificial lighting indoors, especially if you don't have a great deal of space. Whether this is desirable in an artistic sense is of course a personal judgement.

I've been reading an old book from 1963, Camera in Hawaii by Peter Gowland in which he discusses studio technique at some length. Gowland recommends the use of soft lighting for portraits to avoid unwanted emphasis on skin texture in the areas between the highlights and shadows, which he achieved using umbrella reflectors.

Apparent the reason the Hollywood studio photographers used the 10 X 8 format and hard spotlighting for their portraits of movies stars was that the big negatives could be retouched to eliminate this unwanted detail.

Yes, and I often use soft boxes and dishes for the same reason.  Maybe superstitious but I don’t like opening umbrellas indoors, and they have a lot of spill compared to a dish or softbox with a grid.

My point in that question is this: as you are more working on figure, “Even” lighting, minimizing shadows through a low light ratio also eliminates definition of shape, form  and curve. Rather than worrying about “evenness” (by which I think you mean a 1:1 light ratio) going to 5:1 or more and letting the shadows do their thing would yield less “clinical” results. 

I would put you to that it is not difficult to get “even” light in a small space if that is what you are actually trying to accomplish. 

While negatives can be retouched, the ability to retouch would just be one advantage to using the 8x10 negative file. Since they would be destined for a lot of reproduction generations, starting with a large negative as a master copy also meant that generation loss (the bagaboo of all analog formats) was was less impactful, and reproduction could be made with contact printing methods rather that projection methods for better quality control and simple mechanical reproduction.

But! If you actually look at a lot of Hollywood portraiture critically, it is not uniformly “Even”light  at all. 

https://en.wikipedia.org/wiki/File:Oliv … o_1938.jpg

First old time actress I thought of, first image that came up. That is easily a 5:1 ratio.  Note the shadow under the nose. Classic three light set up,  shadows fall to emphasize the cheekbone and jawline.

And, although I was not actually there to verify, I bet that unnamed studio photographer or DoP who took that image had a higher ratio of “Perfectly in focus” pictures than most modern autofocus systems and spray and pray photographers.  It’s all in mastering technique.  Craft will sustain when talent and technology fails..

And this is where some seem to urging you to get “Training”…Reading good textbooks on a subject will only get you so far down the road of understanding and applying the actual craft behind the words in the textbook.

You refer to 1:1 and 5:1 lighting ratios, the ratios between the illumination of the highlight and shadow areas, either can produce good results but what I mean by even lighting is to have all parts of the figure, from head to foot equally illuminated in a standing pose, which can be problematic in a confined space where you don't have room to use large softboxes or umbrella reflectors, What you can do is use white walls as reflectors and have multiple flash units at different heights, or you can hang fluorescent battens vertically on the walls, in either case taking care to shade the camera to avoid flare. Then you can take meter readings at different heights from the floor and make adjustments as required.

Using fluorescent battens in this way in a fairly small space (I use a room which is about 8 ft wide) you can obtain high lighting ratios with cross lighting because the lights are so close to the subject.

The lighting technique used by the Hollywood studio photographers typically involved aiming multiple spotlights directly at the subject from several directions, the photography would be done in the studio during breaks in filming.

Peter Gowland wrote quite a number of useful books, I also have Gowland's Guide to Glamour Photography which was reprinted several times in hardback and Peter Gowland's Figure Photography from 1958, a Fawcett How To Book which originally cost 75c, which in today's money is slightly more than what I paid for it recently on ebay. Admittedly it is a rather tatty copy but these old paperback books are quite rare now. Both these make interesting reading, you would think they would be dated by now but the quality of the photos is still very high by today's standards.

Photographing the Female Figure by Bunny Yeager is another useful book I picked up recently, this has some pictures of Bettie Page that I'd never seen before. These old books from the 1950s are a little quaint in some ways but they show what was possible within the restrictions that people had work within at that time. Not that things are necessarily easier now, just different.

Peter Gowland and Bunny Yeager had very different approaches to indoor work with models. Gowland used studio flash most of the time, whereas Yeager didn't like flash and instead used floodlamps (ie, 500W light bulbs) in combination with available light from windows.

Sorry, I thought the topic was effectiveness of phase  detect vs contrast detect autofocus.  I wasn’t aware that those were options to Gowland or Yeager….I thought they had to use their eyes on the ground glass, probably with a loupe or magnifier.

While it’s not as fast, I personally find manual focus to be more reliable for critical sharpness, particularly in studio. Whatever kind of autofocus my olde Canon 5DS has is pretty darn good for event and location work, but I’m not shooting sporting events or hummingbirds in flight.

In studio, now that I’m mirrorless, manual focus that kicks into 100% magnification if I touch the focus ring (or manually switch it on for a technical camera) is equivalent of a loupe and using the big LCD on the back like a ground glass seems to be the most consistently reliable. The focus peaking color mask is pretty useful on a technical camera but I will still flip over to auto magnification for the critical focus.    Phase One autofocus has improved from fucking terrible (on the 645DF) all the way up to marginally acceptable (on the XF modified with the HAP2 system).  Hasselblad is about the same as the XF with their contrast detection with the 50cfvii , and my one evaluation of the newer phase detection on the X2D certainly didn’t make an impression that it was appreciably faster or more accurate than the earlier style…but I didn’t give it much of a test, about the third time it racked the lens out and back while seeking, (thereby being SLOWER then manual focus), I shut the AF off and went back to the manual focus as described above.  Going to manual focus, for me, just eliminates a potential point of error- I’ll try it again with the CFV100 once it arrives but if it remains “Marginally acceptable” in the studio I’ll just shrug my shoulder as my current work flow will still work.

But I’m not religous, if I’m just out and about taking snapshots, I’ll flip the AF on and use the touch screen to hit the focus point and the results are pretty reliable.

Autofocus will usually be faster and sometimes more accurate but you sacrifice some control over the end result. If your camera has numerous focusing detectors then you don't always know exactly what the camera has focused on or have the ability to control what it focuses on, unless you start messing around with the controls to select focus points, in which case you lose the speed advantage. But the Canon EOS 5 and EOS 50E film cameras are generally quite reliable performers in AF. I don't use the eye control features of these cameras.

Peter Gowland and Bunny Yeager didn't have the benefits of modern (or even 1990s) microelectronics technology but Gowland was certainly an innovator technically, he designed the Gowlandflex large format twin lens reflex camera, about 600 of which were made in successive versions.

There are countless Youtube videos on this subject. I use to experience the same issues until I simply increased the depth of field from wide open at 1.4 to 5.6-8.0. I also have since upgraded to a camera that automatically focuses on the eyes and I have maybe 2 images out of 2000 that have out of fous eyes. Check any of my images uploaded in the last few years.They are incredibly sharp. Another suggestion is shoot from a tripod is possible.

The performance of any focusing system that operates optically through the lens, as distinct from systems using infrared beams or ultrasonic waves will be dependant on the speed and quality of the lens, and also on the lighting. Flickering fluorescent lights can cause problems for some autofocus systems but seemingly not the Canon EOS 50E.
