There shouldn’t be any boundaries in photography.
Regardless of my own ‘religion’ of what I think ‘is’ and perhaps more specifically ‘what isn’t’ photography, my own views are just that - my own views.
I’m well beyond the point of feeling I need to convince others that my view is the only view to have. I think photography is still very much an emerging art. It’s still relatively speaking a very young art form. If you consider it an art-form that is.
You need to find out for yourself what photography means to you, and where the boundaries lie. Perhaps you love HDR, perhaps you hate it. Perhaps you think photographs shouldn’t be altered once the shutter has clicked, perhaps you think it’s only the beginning….. whatever you choose - it’s your prerogative.
For me, the boundaries have become blurred. Graphic art overlaps into photography and photography overlaps into graphic art.
