it depends upon you. You have to justify it by edit the photograph. You have to compare the same photo as color and B&W. my hobby also photography. You can see here "flickr.com/photos/shahed_19/" my photograph
I just checked out your photos and I really appreciate them. Those are photos in Bangladesh that may be common to you but extremely foreign to me and very interesting. I can see beauty in both black and white and color.
no black and white days are gone. When you use camera then I don't think that you should leave the facility of color pics. In earlier days people used to see B/W films but nowadays the time required to give the same film in color. Isn't it
I love black and white prints. They are so timeless and make everyone look a little more swank and a little more glamorous.
I do steam railway photography as a hobby and I usually shoot in color but sometimes looking at the photo on the computer it looks better in black and white. I think it depends on what you are photographing if you should shoot in color or black and white, some things work were other things dont.
I prefer black and white personally, adds a touch of class in my opinion, also...pictures of yourself often look better in black and white for some reason
I like both the types. Some looks extremely good in color & some in black & white. Its all about setting a mood into the picture which must make it appealing!!
