My father understood that if you take enough shots of a subject, varying shutter, Fstop, lighting, angle and pose. After 70 frames you will end up with a exceptional photograph. As a matter of fact it has become a acceptible method of teachinf photography. One of the first thing taught in photography class is shoot lots of film. Bracket your exposures vary the angle. Now there is the famous cliche that states if you put a million monkeys at typewriters you will eventually end up with the Declareation of independence. My father was never into high volume work. He created images not producing photo's The back to back shot of him and my mother was one image not a collection of experiments. He sat her down framed the shot. Then sat down and tripped the shutter. The resulting image at least I feel shows creativity and excellent visualization skills. How many photographers would do the one pweson seated and the other standing behind the chair smile at the camera shot. Put a seamless background behind the shot and at least I feel you have a frameable print to hang on the wall. My point was that you could happen upon that very same photo burning through 5 rolls of film and never know you caught it before you saw the results. To my father this was not professional photography. To him a true professional, someone who is paid to produce an image should be more than a button pusher. He started his career in the 1930's. In a foreign war torn country where film was very scarce. He did not have the luxury of shooting roll after roll of film. You had to produce results on the first or second image. If you could'nt well you were never used again. So he had to develop his skills, of seeing what the camera would see, the light the shadow and the physical attributes of his subject. I suppose if you had to learn and practise your craft in that fashion. You had developed a disdain for those who would burn through rolls of film to get the same result. Modern photography and requirements now let photogrphers readily follow the shoot till you drop technique. Professionl photographers rarely do a shoot with less than 50 rolls of film on hand. Today film and paper and processing is cheap. Back through the 30's through the 50's it was not that inexpensive, developing and printing a 8 X 10 color print was not cheap. Due to the war in many countries silver was a war commodity. So you must sometimes wonder if many of todays accomplished pros would be accomplished if they could not shoot hundred of shots a session. Here is the hypothetical situation. You have to photograph the front of a premier LAS Vegas hotel. This image will be enlarged to poster dimensions and used for promotional advertising. Now you need to create the perfect image and not shoot more than 4 frames. How many can confidently be relied to accomplish it. How many so called notable professionals would be terrified. I suppose it is how you learned your craft, and your confidence of being able to apply it. I guess my father was a "one shot one kill type of guy. Sure you can use a machine gun and move someone down, a lot easier to. The photo of my dad was a promotional picture. He did do kids, but it is the quintesential image of a professional photographer. {Watch the birdie) It leaves no doubt as to the profession of the individual in the picture. Otherwise it could be a photo of a guy holding a camera. He shot tons of film, no he did not document the Hungarian Revolution and WW2 with one shot. I never meant that. I mean that all he would need was on or two shots of any given subject to have a commercially useable shot. He was never a "hold it another then another" Type of photographer. Not that he could'nt, just that he did'nt have to. From time to tim I'll psot some of his works here. Although much of his professional stuff has been lost, over the years after he sold the business and retired. See my mom was has partner in the busines. She handled the books and the studio bookings. When she died in a automobile accident in 1969. Alot of my fathers passion left with her. His heart left the business. My father turning a large B&W blow up into a oil painting by hand coloring. This was one of my first forays into photography, I think I was 12 at the time.
