I am trying to get better at landscapes so my subscribed channels are (in no particular order):
Andrew Marr and Ben Fewtrell, two Aussie channels. Andrew takes seascapes around Perth and generates some lovely shots though for me they are getting a little samey. Ben is more entertainment. He often loses things, drops things, forgets things or completely fails to get a photograph, so I feel quite at home with him. Sydney-based
e6 vlogs. Straightforward clear tips. Not hardcore (he drives to a place wanders a bit and takes a shot, rather than wild camping) but consistently good and very varied content from a wide range of locations around the UK
First Man Photographs - I am not sure this guy is so good but he is better than me so rather than learning from the enormously talented (the three next ones) I feel he is helping me get one step better
Nick Page - Washington State hardcore photographer. Some stunning shots
Steven Hanna - Northern Irish locations. Very easy to watch and learn
Thomas Heaton - just excellent
