Here's what I have in mind: Indoor portraits of my grandmother who's not really mobile. I'd like to use flash on my Kiev 60 for fill lighting but prefer to have the flash not really "noticeable." I'm used to outdoor portraits with natural light but that's an impossibility with my subject. Using a Vivitar flash...thinking ceiling bounce will be the best. Have a very foggy idea of calculating shutter speed based on distance of flash to ceiling plus ceiling to subject...for a test roll, I shot at f16 and all was underexposed....I know I messed up. If I use my in-camera light meter and meter the scene and expose for that even though I'm using the flash...what *might* happen? I have not a clue where to start from here to try to get something workable. Any tips, suggestions (books, etc.) most welcome. Thanks!
