some folks sure know how to take the fun out of things…
the “rules” are easy… its art, there are no rules, merely concepts, and aspects. the concept of art deals with structure and composition, the aspects are the technical things… and theres millions of words printed on the subject. theres a great free library of stuff on piratebay.
imagine if you will, two lines. running alongside one another. one goes up, the other down…
label one F stops, and the other shutter speeds… (now this isnt exact, but its from a 40yr old memory)
F stops f1./f1.2.f1.4/f1.8/f2 /f3.5 /f4 /f5.6 /f8/f11/f16/f22/f32/f64….the F1 is wide open (but most lenses these days start at F2 and end at F22. F2 is wide open, and F22 is closed up. this controls depth of field, but (theres always a but) each stop, lets is less light, which extends exposure values…
now, on teh shutter speed line, 4000/2000/1000/500/250/125/60/30/15/8/4/2/1/2/4/8/15/30/60 (4000th of a second to 60 seconds) this scale runs 4000 at the top, down to 60 seconds)
and we read it off… If F8 shows at 125th of a second, then F5.6 is 250th, F4 is 500th and F2 is 1000th… F11 is 60th, F16 is 30th and F22 is 1/15th of a second…
now… this is why theres no rules… as such… any one of them combinations will give you a corect exposure… but, faster speeds reduce DOF, slower ones cause camera shake… so its a trade off, and thats where the experience lays..in teh knowing.
it all sounds complicated, but it isnt really. you just need to understand the relationship between light, and exposure times…
and now, given that i said some folks take the fun out of it… read your instruction book. learn what every button does, and what its functions can do… all the while shooting frames…. look at other peoples work and say to yourself… how did they do that… or wow… props… and take inspiration from it…
in the real world, put the camera on A aperture priority… let the camera sort out the exposure values, and play around with it… find a long fence or row of cars… and see what happens…
then switch to S shutter speeds, and photograph water trickling out of a tap… and see where the water stops moving…
there are no rules.. we make it up as we go along, based on principles which are ancient…the rule of thirds, or teh golden ratio…
