Black and white photography can make certain styles of photography look extremely good.
Our eyes do not see the same things when in black and white than in color.
Color gives us an emotion that we can tie to the colors in the photograph and can be very busy and distracting at times.
However, in black and white, our eyes are directed to pay more attention to the details in the photograph.
And depending on the editing done on the black and white, the photograph can pop and stand out and grab our attention.
Otherwise it will look very bleak, bland, and flat; nothing is interesting.
