I see a bunch of day shots, not night and day shots.
Significantly different can take lot of meaning. For example, in Yellowston speed limits are likely 55mph, In Calgary (the Bow river) 100kph. Different and yet not. Accents are different to but the same language is spoken.
Weather.Similiar
Fish species and methods? Similiar.
Scenery. Similiar
Wildlife. Similiar
Disagree with any of tha?
To be sure there are differences but sorry not night and day differences. If I hadnt done either, theres nothin in your photos with the exception of 1 thats says ones “significantly” different than the other and certainly not night an day.
