Pavel,
As per Gail's question earlier your third picture would not qualify for the challenge (even though I love it). Would you like to swap it with your bonus picture or submit another?
Thank you for the offer, but the bonus picture contains more colours than the third one...
I actually do not like almost all B&W photos, but in my gallery there are several - I tried to rescue bad photo by conversion to B&W (blown highlights, disturbing background,...)
About Monochrome:
I think that my third picture contains only blue colour, if it is not true, than I think it contains 3.5 colours: blue, black, white + many grays
There are many discussions about this problem, I do not want to start another.
The sepia is problematic too in such discussions...
And what about:
This is beauty of these challenges - one person give the rules and judge the winners, thus I respect your decision about the fitting the theme.
And I think that no one has right to change her/his nomination - it would be unfair to change the picture set according to the subsequent comments.
Thus I appreciate your goodwill, but I continue the challenge with the first two pictures.
Pavel
PS: It was not premature step - I thought that it could be a problem, but it was my risk
PS2: Your words: "(even though I love it)" are big award for the picture, thus I do not regret, that it was included in my selection ;-)
