Canon or Nikon will do. But what matters most is your skill on photography. There are classes where you can learn photography or you can read tutorials or research on net on some tips on taking pictures and photo editing. Proper usage of aperture, shutter, program or manual mode will have a dramatic effect on your photo. Then you can buy lens which suit to your subject. Lens type will greatly improve your image.
I think has the best option for the entry level photographer if you want to get a DSLR. You can't go wrong with Nikon either. I have started with an older model of a Canon Rebel DSLR and after working with it for a few years I will eventually get a full frame. That is, when I can afford it!
Last 2 months i also trying to take a camera and not conformed with will be the best. But i have seen a rating comparison with features and their clarity and also their prices. Their was Sony at the top. Their services also good and available all the places.
Canon EOS Rebel T2i SLR - 18.0 Mpix - Canon EF-S 18-55mm IS lens - optical zoom: 3 x - supported memory: SD, SDXC, SDHC Best suited for still photo graphy. It can aslo be used for recording movie. But Still is its signature.
As a professional fashion photographer the Canon 5d Mk II is very good! It all depends on what your budget is.
There isn't really a camera that's best. "Better" cameras are pretty subjective, some just make getting the job done easier. I personally use a Canon EOS 50D, absolutely wonderful camera. Handles high ISO levels like a pro and I never feel restricted while using it. If by nature you mean, landscapes; a Canon/Nikon full frame with a good quality wide angle lens would be the best. If by nature you also mean animals, then a cropped Canon/Nikon camera with a good quality telephoto would be the best option. However, if you are new to photography just buy a simple point and shoot and hone your skills from there and scale out.
