I do not understand why some of the challenge categories are selected when the title of the challenge is not explained, i.e., what does "Paisagem" stand for? Lions and Tigers? How many of us have seen lions & tigers outside of a zoo? India? How many of us have ever been to India or plan to go there? Hyderabad???? Angela Marie Monroe??? Who is she? What kind of photographs does one post on her challenge? So, how do we photograph images that fall into these extremely specialized challenges? Where do people go to photograph lions, tigers, scenes from India, etc. Most of our photography is creative...so why a "Creative" category? I think the challenge categories should be scrutinized more by the administrators and selected so that most of us can participate in them. And, btw...who does select the Challenges? I feel extremely limited in submitting photos when there are so many narrow theme challenges that I don't understand, or when it would be impossible for me to photograph subjects within the category, i.e, India and Hydrabad. I am relatively new to Pixoto and am beginning to get discouraged.
