I still use 4x5 cut film for landscape photographyEven that sounds technical to me. I'm the gal that's running into Eckerd on the way to some event buying the disposable.
F zero has been a Godsend and tries to help out dear ol' Sis. He has a career in the industry, you might say, and has recommended a number of good cameras and even gotten a few for us as gifts. I try.
Well (without being too technical), the larger the negative the denser and more detailed the picture. 4x5 format uses a sheet of film instead of a roll - each piece of film measures 4 inches by 5. You put each sheet of film in a holder that fits on the back of the camera - to expose the film you open the holder and then trip your shutter. Ansel Adams got his beautiful landscapes with an 8x10 which is of course twice as large as my 4x5 view camera. He also used something called the Zone System,
but we won't go there, I'm not even sure I fully understand how it works, I just do what the book says.
I've been assisting my DH by holding camera stuff for 35 years (we've been married for almost 30 but dated before that.) You're bound to pick up some knowledge along the way . . . as my dad says, even a rat can learn in a maze.
