I always wanted to get into basic photography with Nature like mountains and I wanted to hike up into Snowdon or Lakedistrict and do a long exposure photo, do you know of a good camera? If not I get it since not all photographers know EVERY camera as most just focus on the one they have.
from what i understand, long exposures and stuff can be a pretty expensive setup if you want it to look decent. generally speaking you're looking at mirrorless or dslr level, i don't really know that anything below that will give you the result u want
for long exposures u really just need a mirrorless/dslr with a good, sturdy tripod. naturally more expensive dslrs are gonna have shit to prevent camera shake which is essential when you're doing longer exposures, then ur also gonna most likely need a wide angle lens
honestly i've not done a lot of research on long exposures so i could be talking out my ass here, it's not really something i'm personally interested in doing
yet. w/e can keep the shutter open for ages and has stabilisation features, a tripod that does its job, a wide angle lens (ideally with stabilisation too), etc.
in terms of just general landscape photography, though, could honestly be anything and it's genuinely just down to how much money ur willing to sink in. any camera with a wider angle lens (ideally 35mm and below if we're talking smaller format DSLRs, not sure about anything below that) is sure to give u a good image provided u practice, but considering nikon/canon/fujifilm etc all have beginner DSLR options im always gonna recommend u go that route
at the end of the day bud the camera's just a box that funnels light through a lens, focuses it to a sensor and records the image captured. u could be using a $30,000 setup or ur fucking phone, the only real thing that matters is the person behind the camera.
