Which is more promising, the landscape architect or the photographer?

I am just the opposite of you. I am a photography major, and I like gardens. Anyway, don't be too entangled. The problem now should be that you do a good job first and get a university (undergraduate) diploma within two years. This is very important. It should be easier to upgrade from university to undergraduate. Landscape architecture used to be a "city dweller", but now it lacks talents, especially experienced and knowledgeable people. Photography can be learned in five minutes, and it may not take 50 years to learn it well. Just like me, there is no good work if you play with the camera every day, and there is no good work without passion. So you should protect your "rice bowl" first, and then decide what kind of "rice bowl is filled with" in the future.
