I am writing an article for a newish photography publication in Bristol. the article I am writing is on early street photography and I was hoping to use some images by some well known and lesser known street photographers. Does anyone know how it works with reproducing photographs in this way? Do you just need to cite the image source or would I/the magazine need to pay for the use? If anybody knows anything about this sort of thing i would appreciate a professional opinion as I am rather new to it all. Thanks.
