I feel that you have to make the focal point more interesting. It isn't enough to smooth the water out.
I think Stamper is right; one can indeed get caught up in the experiment rather than in the image the experiment is producing.
I see... these are my first experiments with this technique, indeed; now I know how I must improve in this field, thank you.
As an idea (dangerous to offer them, always!), in the shot with the two depth poles, why not clone them so that the two show the same level but at clearly different heights? A sort of visual joke... I accept that humour is a deadly game.
I liked your advice as soon as I read your message, and I liked it even more when I saw the results; brilliant idea, I hate you now.
This joke brought back to my memory the work of Chema Madoz
(no implicit comparison, of course); his portfolio is worth a visit, in my humble opinion.
Three nice abstract studies.
I prefer the first one.
I like them. They have a classic elegance. The water is subtly there, but isn't really the subject.
I am glad to know you liked them; thanks!
