i read a blog post a couple days ago that inspired me to do this post. basically, i think that black and white changed your picture. it gives it that satisfying professional look.
my first example is a flower. i love how it makes the flower look.
this next photo is a black and white version of the swan picture.
this one is a tree picture that i love and it looks awesome in black and white.
the last picture is of flowers again, this time the black and white gives them a kind of vintagy look.
sorry that this post wasn't very wordy, i just think that black and white sorta explains itself!
don't forget, tomorrow is the last day to enter my Sparkling Saturday contest which you can do here!
