never done this before. will already told me i need a red filter and all that jazz... but i was hoping to maybe get some more guidance just on getting decent exposures so i don't waste more film trying to get this right than i have to since it's not cheap stuff. is it a whole lot different than shooting regular film, or should i be alright? i'm worried! any tips, tricks or warnings you folks can give me before i try my hand at it? are there certain lighting situations that should be avoided? i'd appreciate the help immensely! thanks!
