Which teapot do we want to dedicate for this tempest?
Again, there was this Photography 101 Assignment - "Go and photograph something never seen before."
At first, daunting. Then the thought: Expose a sheet of black and white paper to ambient light, and develop for maximum black. Title it, "Black Hole". Claim it is a photograph of a black hole - never seen before - and STILL not seen. Of course, there would be no background of stars ... but there was no mention of including something that had been seen before.
Then, after further thought ... the easiest assignment possible. Every time we photograph it is "something never seen before." We could, and always do, see something "similar" - but never precisely the same.
Even if we go to a well-worn site of a great photograph, and use the same tripod holes, the resulting image will be different - the cloud formations will not be the same -- nor will be the light - sun position for the seasonal date; diffraction in the atmosphere due to moisture and dust; changes in film emulsion/ processing, lens characteristics ... it is possible to think of an infinite number of factors.
I can't even duplicate one of my own photographs ... I'll revisit the scene - and my "vision" will have changed - the light is different ... etc,.
I would never worry about something someone has done before. Everything you do will have been influenced in some way, by previous images you have encountered ... but your work WILL be unique.
Work in good faith. Nothing else really matters.
