I believe a Bachelor of Arts would be more suited for a degree in photography. You can further major in digital arts, photography, photojournalism, general art/art studies, and general visual & performing arts.
You do not necessarily need a degree at all for photography. You could take some classes and learn the ins and outs without getting a bachelors degree. However, it can be beneficial to get a degree in photography or an arts degree of some kind.
If photography is your passion and you don't see that changing anytime soon, you can look into a school that has a photography program and be specific with that. You could also do something more broad and go for film/video, or art.
I hope my thoughts help you.
1) This is something that you can learn from on the job experience, especially if working with a really good professional.
2) This is a field that depends on technology. Technology is changing at a very fast pace. Professional television shows are now routinely shot using cell phones. YouTube videos are routinely produced with low budget hardware by people that are not professional photographers (they may still use professionals behind the camera).
You asked another question. "Is photography easy". I think the correct answer is pretty much the same if you asked it of my profession (computer programming): "It can be easy or it can be hard. It gets easier the more you like your field, but if you are serious there will be times when it is hard."
Good luck in your career!
