so i searched for info on the topic but failed to find the info which satisfies my curiosity. so, i will be using a minolta x-370 slr camera for this. does it matter which lens i use? the only lens which my red#25 filter will fit is a minolta MD 50mm f/1.7. i hope it works... 1. so like i mentioned previously, i will be using a red #25 filter, so does this change the process from what i would do if i used a different filter? 2. as far as focusing goes, should i be focusing on the forground or background? in the middle? 3. ISO setting on camera? 200? 4. my buddy told me to bracket each shot, so for each pic, i take it 3 times. so should i take the shot, then open the f-stop up once, take it again, then close the f-stop down to one below the original? 5. how do i use my light meter? i probably dont, so is this a guessing game?
