As part of my efforts to continue improving my photography, I've been trying to research and study the work of other great photographers. I noticed that although I've always loved photographing inanimate objects & wildlife, portraits and shots involving people consistently seem to grab me the most.
I am particularly enamored of the portrait style of Yousuf Karsh for example, with his beautiful B&W tones, lighting, & connection to his subjects. I also noticed that consistently I seem drawn to B&W portraits done with large and medium format cameras (both film & digital). I'm not sure why the medium & large format work is so appealing to me, possibly it's something about the detail captured or large dynamic range has an effect. All I know is I consistently single out images I like and later find out they were done with larger formats. Probably not the ideal look for a m4/3 user to be aiming for, I know
Anyway, what I'm looking for is any recommendations on resources (books, websites, videos, workshops) on portrait photography. I've no in-depth experience with supplemental lighting, post-processing, posing models etc. so I've got plenty to study up on at this point. Just looking for some general pointers at this stage. And of course, resources geared more towards the Karsh style of portrait versus glamour or fashion work would be ideal.
EDIT: should clarify, I'm not looking to "ape" Karsh or anything, just interested in B&W portraits and lighting styles
Thanks in advance!
