Well I am guy originally from Nepal and now a masters student in environment science in University of Toledo, Ohio, USA. For me photography is not a profession not a hobby but just a way how i like to feel comfortable. I like to click thats it, I am learning things and I have no professional courses on Photography. My interest lies on Wildlife and Nature Photography. I was also a national semi finalist in photography back home. I also worked as a coordinator for the nature photography contest back home from my office.
My Photography Equipment:
Well I have a 3 lenses 18-55mm lens and a 70-300mm VR Nikon lens and few filters, Nikon 50mm AF f1.8 lens. A 72" tripod.
When photgraphing wildlife, animals can move unexpectidly, leave room around them, do not zoom in tight to the body.As I said with the mallard, you have got a nice close up of the body but where is the mallard going?
Look at what the professionals are doing, they are now showing the environment that the animal lives in as well, just like you did with the squirrel.
