afaik the world is actually awash in electromagnetic radiation across a wide spectrum of frequencies; a very small part of which we sense as visible light, a tiny part of which we sense as heat on our skin, and a tiny part of which we sense as sun burn.
"B+W" photography is no less a transcription from the world, because it does not differentiate frequencies in the visible spectrum.
Infrared photography is no less a transcription from the world, because it records EM radiation at a frequency we do not see.
Except that is of no relevance as you missed the point. Yet again.
We see in colour not B+W, not IR, nor any other par of EM spectrum. So by not shooting in a normal colour space you are changing how reality as seen by humans is depicted.
B+W is only accepted as 'real' as it came before colour photography and thus became accepted as the norm. However if it had been invented afterward colour, then it would possibly be along viewed with other looks such as HDR or hyper saturation as unreal and therefore not acceptable in photojournalism competitions.
"However 'creative' a photographer may be, he is ultimately dependent upon what physically exists in the world: no filter made will transform a frog into a prince. On the other hand, music, as Stravinsky stated, expresses only itself -- its laws, its forms, its -- not the world's -- reality. Consequently, the composer is, in an absolute sense, 'freer' than the photographer; so, too, in the framework of picture making, is the traditional artist."
John Caponigro quoted in The Wise Silence
Oh yes, you're right people who write music can make up new notes and other of music all the time. Oh wait they don't do that at all.
They use the same few notes and the majority of the time in contemporary music at least, they also use the same structure [4/4 time] on which to hang the notes. With the rare dabble into 3/4 or 5/4 time.
So composers are just as constrained, albeit in a different way.
Besides photographs can be expressed in other ways with their own laws and realities by such photographers as for example.....let me think, oh yes - John Caponigro with his gravity defying flying rocks.
