This entire article is preposterous. It shows an utter lack of knowledge and understanding of photographic technique. Go back to school before you try to pontificate technique to unwitting readers!
What the heck, for instance, is all this convoluted and unnecessary reasoning about getting the right exposure in a studio setting with strobes by resortingâ€”if youâ€™re only thinking about itâ€Šâ€”â€Šneutral density filtersÂ indoorsor changing ISOs, etc.to control exposureâ€Šâ€”â€Šwhen all you need to do is dial-down the output of your strobes. You donâ€™t have to blast the entire output of a capacitor every time you make an exposure. Buy a flash meter if you have to! Youâ€™ve got a goddamÂ screento preview your results. People who actually understood what they were doing had to use Polaroid film to test exposures and the working mechanical order of their cameras, lenses, shutters, and strobes. Photographers whoâ€™ve known nothing but digital have got it so much easier. ExceptÂ youstill donâ€™t get it.
As for choosing an f1.2 lens, again in a studio setting, because you want shallow depth of [sic]focus (I think you meanÂ depth-of-field) by shooting wide open, how about, instead, you learn how to control depth of field with the judicious use of focal length; not aperture. That way you might also learn how to control perspective and shoot at median apertures for optimum optical sharpness.
Geez! This is nonsense.
