For landscapes I like the low light, either winter or the golden hours, ideally very diffused. But sometimes have to make the best of what is presented.
This morning it was big surf, contra jour. Yesterday nice diffused side modelling of some rugged coastline in the rain.
though my favourite light is at sunsent, i shoot at whatever light i have available when the will to shoot something comes. I don't have have much time of my own to be able to choose at what time i'm gonna shoot something i'm thinking about, so i grab what i can get.
even midnight
Since I'm always shooting outdoors I have no real control over the direction of the light as such. I do tend to prefer overcast days as opposed to bright sun because I feel that direct sunlight is just too harsh 99.9% of the time.
I could not pick one from the list above, because for me it's more about the sort of light than it is about its direction.
So daytime and season plays a role. What I do not really like is bright sunlight at high noon, that's worst case for me. Travelling foreign countries you can't avoid it tho. For B&W i like the diffuse light under a bright but covered sky best. Gives a good 3d impression and fine details, rich greys. C41B&W can produce amazing results with this light.
