So informative, thank you! but I'm not sure about vertical images in documentary photography, our eyes see everything close to horizontal and horizontal picture seems more natural. The other one looks like cropped images to me
You're welcome! I think that's a perfectly fair take, and I can see where you're coming from with that. I agree you have to be careful with cropping, orientation, and even aspect ratios to some extent. I personally think, in documentary photography, that portrait/vertical images are perfectly fine used in the right way. To focus in on an item or a feature, to capture a portrait that focuses on the individual and their clothes rather than the environment. It's a way of embedding some context and somewhat of a guide for the viewer, so they know which information is relevant/important to the narrative being told. Certainly something to be used sparingly and thoughtfully, as you are correct in saying it's not as natural. That's just my take on it though.
