I think our northern latitudes are lucky with the positions of the sun and moon. I once looked at southern countries and Africa for interest – there the sun "walks" across the sky almost vertically, while ours is low and all over the horizon, especially in summer.
The advantage is that you can combine celestial bodies with different architectural elements at different points.
And they combine well because of the low angle.
If I've been familiar with photographing the moon for more than a decade, then I've only recently started exploring the sun.
The sun in the frame will always be round (except for eclipses), but you can photograph it through clouds or haze.
The moon has other features: its variety of phases and positions give more scope for creativity.
But the moon also has its drawbacks.: it is bright only at night, it is almost invisible during the day.
If the moon rises or sets when the sun is shining, it will be almost invisible.
And if the moon rises or sets at night, in total darkness, then on the contrary, it will be too bright relative to the black sky.
The sun and moon are the main two luminaries in the earth's sky. And it would be interesting if we had many moons and more than one sun...how many interesting views and angles could be captured!
