Hi Katherin
Personally I think that doing a B / W process is such a great option to create at any time because all the colors in a photo are more specific and the B / W lets you imagine and have perceptions and options for not classifying but trying to have different perspectives in the photo.
I love the B / W process but the noise can be a positive aspect when you know its there. Also, I see you get several effects on both types of photos. Keep exploring this interesting world in B/W
