If someone is spending hours 'creating' an image in photoshop, then they don't want that to be seen as a 'photograph' because to do so completely ignores their artistry. Photographers quoting this kind of 'example' are miles wide of the mark.
And thats my point it isnt a photograph anymore at all it is now computer generated art which in itself is a incredibly difficult thing to do well and i admire them for it, but is it photography? The worlds best artists used brushes and that love and passion for the art would show but if they had of created it on a computer then how would the artist have been able to put his heart and soul into his work? I can see i will have to drag myself kicking and screaming into the real world if i want to progress further with my photgraphy or maybe im to much of a (when i was a lad) type of guy lol.
But I'm afraid if that was your point you didn't make it clear.
Your posts are all about 'cheating' and Photographers pretending that their 'digital imaging' work is being passed off as photography. When it simply isn't.
We all have lines we won't cross, but when you start threads like this and use broad brush statements it makes it look like you're just anti-processing. And that, as many of us have pointed out, is ludicrous.
So from your example, cleaning up the sail on a yacht, ok.
Enhancing the sky, ok
Adding a different sky, would depend on the circumstances.
Adding loads of other boats, no longer a photograph.
As far as 'when I was a lad' it's somewhere between a lack of knowledge and rose tinted glasses. As many of us have pointed out, between the light going through your lens to the print, there is processing. Whether that's done with automatic software, processing machines for film and print or a completely artisan process, is a matter of personal preference.
But as others have said, it's an important part of the process and has always been done. You can choose not to do it, like you can choose to be sloppy with any other area of your photography, but it will show in your results I'm afraid.
And for the record, an artist working in digital will be putting as much 'soul' into his work as he would working in paint. I'm sure there were many 'traditionalists' who got upset when upstarts started using pre-prepared pigments, and again when they started using synthetics that dried quicker.
