As I promised Mark (mknittle) in Nandakumar's thread named 'Locks' , I'm uploading four B&W conversions of the same lock. When Mark asked me to upload a B&W conversion of my coloured lock image, I didn't know much about SEP2 and I was only able to apply the presets in the software. After reading the books about Nik Software and about B&W photography, I think I'm able to make B&W conversions more consciously.
The first three of the images were edited in SEP 2 without using any presets . I have to tell you that examining presets helps a lot to learn the functions of the sliders in the software . So although I read a book about the software, I have examined the presets too.
I edited the forth image in PS CC.
BTW, the original image is a JPG and an old one. Because I wasn't shooting raw when I first started photography.
C&C are appreciated as always
