Start with 60 or Higher as the Shutter Speed
Later Dad went through and made a cursory explanation of all the controls and told me that I wouldn't need B right away, but that it kept the shutter open as long as the trip-button was held down. He also explained how to take a proper reading for a face by reading about a eight inches away from my hand. Anyway, I figuerd it out and it stuck much more solidly than it would have had he given me a straight answer earlier. But I guess I thought he was just being difficult until just now. I wonder what my kids think.
It was proper advice. You are probably safe using 60 (1/60th second) as a starting shutter speed, if your subject is not moving. This gives you a good chance of havinf an f/stop that will work wiht it. You increase it to stop motion as needed and allowed by film speed (ISO) and aperture. Sometimes you will stop speed by following the moving, called panning. Sometimes you want all or part of the motion to show blur. Sometimes you just take what the light, film, and lens allows you. Sometimes it will allow nothing. This is about the time when the flash and or the tripod was invented. Actually it likely happened almost in reverse.
I had the Yashica 44 LM (or EM). It had a built in light meter. I was really rock'n and roll'n. Of the more than a dozen 44 TLR cameras that I have now, only one has such a feature. What was don eprior to such advances? If your answer invloves a stand-alone light meter, you are only partially correct. It was considered living in tall cotten as one of my old farmer uncles used to say. Or maybe it was high-cotten. Anyway, it was a luxuary to have a light meter of any kind. Photographers had gotten along for a century os more with out light meters.
I must say that I never used an extinction meter, but I knew what one was and I have seen a couple of them. They were non-electric devices that were to light meters what pinhole cameras are to cameras with lenses. They worked on principles that i won't get into right now, but which have something to do with squinting your eyes until you get a suitable image. And they are about as effective. Although I have heard that some peopel became quite ept at nailing the proper light readings with them.
For the most part, photographers used to rely on charts that came with their film (and still do), either rprinted inside th ebox or on the piece of instruction paper printed in seven languages all of which are in characters to small to be anythign other than Greek as you get older. But if you squint you can read the tables that were once relied on so often. Pictured below is a typical chart as was often printed on the back of TLR cameras.
I didn't take this picture the crooked angle makes me crazy. I grabbed it off of a hndy eBay listing, but it was not water-marked. I do like it for illustrative purposes regarding depth of fiesld. Notice how the nubers below, being farther away from the lens begin to blur. This is a example of where the depth of field is too shallow. It could be cleared up by selecting a smaller aperature, using a wider-angle lens, backing up increasing the ISO, or increasing the illumination. And actually part of the blur may be due to lens aberration from being close to the edge of the image. But more on all that later.
This was the basis of most properly exposed film. Beleive it or not once you learn to identify the lighting conditions refered to, the tables absolutely nail the correc camera settings. These can be further transposed on the fly for different film speeds once you memorize these.
At the top of the table it assumes an ASA (ISO) of 100. If your are using a faster or slower speed, you merely adjust by either halving or doubling the number previous to or subsequent to the last doubled number. In other words, if you are using ISO 400 film, it is first doubled once to 200, then the 200 is doubled to 400. ISO is calcualted an dexpressed by doubling or halving the film sensitivity. The higher the number, the more sensitive, or faster the film is.
As guess we say faster to refer to both the light gathering power of films and lenses, because they would enable you to come closer to freezing faster moving subjects than would slower films or lenses. It doesn't make much sense otherwise, but I didn't make it up. Actually with films it probably originally had to do with the faster chemical action cause by light on the silver halide film emulsion, and then the lenses were called the same because of the similar end results. You know--I don't know. I'll have to research this--in the next life. It only matters to the inherently curious.
The top part of the table evne qualifies the numbers by the time of year hen the suns rays would be effectively brighter (except of smog and such). The top line then has a row of succesively larger f/stop numbers, which means successively smaller aperture openings: f/ 3.5, 5.6, 8, 11, 16. Below these f/stop are lines pointing to shutter-speed numbers starting at the cameras highest--1/500th (500) and descending through the numbers to 1/2 second at the very bottom. Incidentally, each incremental increas eor decrease of either f/stop or shutter speed exactly decreases or increase the amount of light reaching the film. Very easy to work wiht this way.
The bottom of the table also does some of the thinking for you and provides a set of f/stop numbers for use with ASA 50 film, which is not used that much today, except by professionals for specific applications requiring ultra-fine grain and other characteristics. But notice that all the chart-maker has done is to shift the numbers to the right one f/stop to reflect the less-sensitive film of 50 ASA sensitivity.
Then in a finalo attemt to assist our inferior English-language ignorance, the helpful chart-maker tells us that during the months of April, September, October, November and when there, curiously, is no sun--that we must double the above f/stop numbers. Again the theme of halving or doubling comes handily into play. Our friends at Kodak a century and a half ago helped standardize these numbers to keep it simple. Yes, I think I will increase my shares of Kodak stock at once.
Now if you are still with me, run your finger, or at least your eyes down the extreme left column of the back-of-the Rollieflex chart where there is listed a ariety of potential lighting conditions. (1) Sea-shore, or high mountains is the first conditions, followed by Sports scenes, bright lights squares, land dscapes, distant views. And on down the column different potential lighting situations are proposed.
The trick is to understand what each of these references to lighting situations actjually mean. They are a lot less subjective than you might think. The camera book or any good camera manual will tell you more precisely what comprises each of these lighting conditions. and although this is not the same set of standard lighting conditions that I learned and still often use today--it is based upon the same priniples.
At a much earlier post regarding ourdoor portraiture, as I recall, I explained my system. It is based on one one f/stop and shutter combination, namely f/5.6 at 1/125th (125) shutter speed. This is using ISO 100 film--and is based on a fairly definable lighting condition called open shade. Note that some cameras have settings of 100 instead of 125 and so forth. Don't worry, it will work well enough.
This is the earlier post and it is discussed for the next couple of posts following this link. Bookmark it and come back to finish this post: http://notesandnods.typepad.com/photography_for_profit_or/2007/05/outdoor_portrai.html
From this one combo, any lighting situation at any film speed at any location between dusk and dawn can be nailed--given some practice and use of the system. Although each person mayh percieve lighting differentlyh, that is subjectively, it doesn't matter, once he know how the system works for him it always works with or without batteries, I guess as long as this person can see.
The human eye, with a bunch of help from the brain, can be trained to distinguish 256 theoretical shades of greys, reds, greens, or blues--using one particular color model--this translates into 16.7 million color/lighting combinations. So it is certainly reasonable to expect virtually anyone who can see, to learn a dozen or less different lighting conditions.
From these and the one magic combination of 5.6 at 125 with 100 speed film can be used to extrapoloate, on the fly any camera setting required. Amazing but true. wiuth me,m it works a lot like listening to Morse code, which I leaned at about the same time in life--the fourth and fifth grades. If I was asleep and heard proper Morse code blaring from a shortwave radio, I would not be able to sleep for autonomically and involuntariloy interpreting the code into letters, words, numbers, sumblos, acronyms, sentences, paragraphs, and ideas.
This should not strike anyone who is bilingual as strange. You hear it or you see it, and you understand it even before you can translate it. It is the same when you understand the language as it were, of lighting, f/stops shutter and film speeds. I have an unnticed, but constant dialog about the light around me. After a lifetime of use, many photographers can fairly nail the proper manual camera settings without much trouble. But it is a dying art, rendered mostly unnecessary by the marvels of science--but it is still useful. And this was the way it used ot be done.
These sytems were and are commonly used to determine setting for manual cameras without the benefit of light meters or extinction meters. I thrill at the wonderful science of modern computerized electronic metering systems (this is exactly what is on board any new camera). But i also marvel at the capacity of the human mind to do the sme things, often faster and better than any current device.
What about flash photography? Glad you asked. I will one day soon make a blog entry regarding how to use the magic of guide numbers to determine what setting for your camera and one or more flash units. It is even easier than the method for determining natural lighting settings.
