This guy is called a pro by many. He uses a Ricoh GR1 or a GR21 and typically doesn't even compose in the viewfinder. I am pretty sure he uses his camera in full automatic mode. His prints sell for $1000s. In Japan, he is considered a Master of Photography. But you'd have to expand your definition of what constitutes a pro to wrap your head around his art and mastery.

How a picture is recorded and processed is a workflow filled with lots of choices. Image manipulation for artistic effect is one of them. And no, creating a perfect image in a camera without post processing is not the mark of a pro. The final image is. Also a pro can be a commercial product photographer, a portrait artist, event photographer, wildlife and nature, sports, fashion, food, etc etc etc - and each have different standards for their specific piece of the industry. The only ones where the picture goes straight from the camera to print or publication are the documentarians - reportage, forensics, crime scene, etc. But these images are typically boring and not creative in the least. Not something you would see in a gallery or museum.
