For me, there's not actually much of a difference between Landscapeand Cityscape photography. Or any photography, for that matter. To me, it's about light, angles, geometry, leading lines, ratios, balance, composition, and - most importantly - the FEELING. My photography typically has little to do with the actual subject of a photo. Obviously to have a composition, there has to be a subject and sometimes I do use a subject to make a point, tell a story, or what-have-you. But more often than not, I'm going for a feeling.
Comments and critiques that focus on the subject will more than likely miss the point of my photos. For example, if someone tells me, "That's a great photo of the classic red telephone booth" first, I'll say thank you. But second, I'll ask what they feel when they look at the photo or what else they see besides the subject (ie the red phone booth). I may ask questions to lead someone like what do you think about the colors, the stark contrast of red and subdued, red vs pink, the flags, the deserted wet streets, who uses that phone booth or mails letters in that box? And so on. Because, to me, that photo isn't about the red phone booth.
That's what I'm inviting people into with my photos. And while Cityscapes are relatively new for me compared to my Landscape work, I'm just as excited to tell the stories and share the feelings.
