Several of my recent posts over the past few days/weeks have been somewhat argumentative or even rantings. Apologies if I have offended anyone. I've been struggling recently to figure out for myself why I enjoy taking photographs and what I'm really hoping to achieve with my photos. My own internal struggle has spilled over into my comments. It's my problem and not something that I should be inflicting on the community. Sorry to all the posters whose threads I have derailed. Mea culpa.
