so when i've been shooting lately, i've found that i like to deal with absolutes. in that, i use a really open ap or really closed. and if the metering tells way different i'll correct. but i began to wonder... having the luxury of a digital camera, i can shoot stepping up or down in as small increments as i wish and see the results immediately. however i wondered how people using film cameras can find the sweet spot in the "Gray" area of the settings?. for example, my shutter speed can go from 1/4000 of a second to bulb. i mean sometimes a faux pa and i correct it. but i was wondering how people using film cameras (and digital too for that matter), can find the exact settings they need on a dime?
