I am interested how (technique) and what (tools) you use to make good portraits with LF 4x5, 8x10 and larger. How do you control the focus in studio or outside on travel or in your backyard. What is the best approach if you do portrait of people you meet at their environment. Don't people tend to move when you put the film holder in place and pull the dark slide? I am planning to do a trip with 8x10 and hopefully make some good portraits. I would love to hear your story what you end up with. Thanks for reading.
