This "leave something to the viewer's imagination thing" is an identifiable crutch BTW.
You misunderstand its purpose. It is not about the viewer's imagination; it is about the viewer understanding what is going on without needing to see everything. Photojournalism has the added benefit of using captions to explain, and to place an image in context.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
