Far too many photographs are made with nothing more in mind than the photographer’s comfort in mind (if indeed even that much thought is applied to the process).
I quite often see photographers, mostly the iPhone variety (and this assumes you consider most iPhone users to be photographers and frankly most of them are not, they just take pictures – Discuss) lift the camera above their head to see over a hedge or a crowd but how often do you see a photographer kneel down or lie down. I could count the occasions I have seen that on the fingers of one foot!
Portraits of people are mostly taken with the camera at eye level with the subject and for very good reasons, so if you are photographing someone in a wheelchair would you kneel down? Most would not. Taking a portrait of someone’s pet Dachshund? Get on eye level with it, lie down. Think about it and you know it makes sense. Get down and dirty; you will take better pictures.
