Gwyn have you played with circular polariseer filter... Dammit that it bring more punch to the picture...more precision,more contrast...The distorted ligth remove from the picture you get only the best...I whas taking a lot of nature picture here and there and whasnt able to get punch out of it....whell now i do...It is a shame that affordable numerique lack of lens mounth... To return to your picture i prefere the color one... I dont know if you are actuality thinking like me... I found that to convert a picture in B&W of good crisp contrast the original must be really realy good. I whas use to devloppe b&W to get what i whanted to be well define..Since i did Not really work on the color to b&w very often...it is like there is some punch lost in the process of the conversion....Do you have any trick...
