Also, a question, if I may ...
If there were a beautiful sunset,
In manual, with a low f-stop, a fairly quick shutter speed, and if it wasn't all that bright so maybe an ISOthat isn't very high... Would I be able to achieve a nice shot ?
How would you set your camera and why ?
You need to understand that there's no such thing as 'go to' settings, the only guidance you can get is what and how for
technique. For sunsets we generally meter the sky. It doesn't matter what mode you use, as long as you understand what you're metering and how you use that metering. For multiple similar shots M might be the best option, but for keeping your options open for different effects, AV would be quicker (locking exposure as you go).
So for your example, I'd shoot a sunset at a fairly large aperture, unless I was after foreground detail (then I'd perhaps stop down to f8), a shutter speed that'd allow me to handhold comfortably, so the ISO would be dialled in to suit that - always looking for the lowest ISO possible.
I'm in the midst of a blog post to show the difference between
'using a camera' and
photography based on a recent sunset shoot I did. Just to show there's no such thing as 'right', because it's about creating the image you want to create, not simply something that's in focus and well exposed.
