When it comes to photography there are in my opinion two particular periods to get that wow shot; these are when the sun is close to or over the horizon.
When the sun has not risen or has just set the sky can turn a beautiful pink, orange or blue and water turns to various shades of blue or green. Sometimes you get this affect when facing away from the sunset as in the picture below facing East:
You can get a fairly good sunrise if there is not much cloud about, but bring out the black ones and you can get something really dramatic:
The thing is that with a little planning and an eye for composition most people could take this kind of shot, but most do not. You may well ask “why not” and it is because the planning for most of the time means getting up bloody early. In winter it is not too bad getting up, but there is the low temperatures and maybe a strong wind that makes it feel like -10. So part of the planning would be to wrap up warm, have a fully charged battery or batteries, an empty memory card and get to your chosen location 30 minutes or more before dawn or sunset. As the sun has not risen or is just setting, the light can be low, so pack a tripod. Another feature of these shots is that the light can throw out the light meter on the camera, so you will need to read the manual and practice setting a bracketed exposure.
The good thing with bracketed exposures is that either the normal, under-exposed or over-exposed shot will be correct. The bad thing is that you can eat up the capacity of the memory card 3x faster, but as you will have an empty card to start with and you will be only shooting for around an hour at most, things should be OK. A benefit of the bracketed shot is that with the over-exposed shot its high key lighting may suit the picture best, but you may have never have deliberately chosen to take that picture. Then again the under-exposed low key dark shot might be more dramatic and moody.
Remember that you can always delete anything you do not like when you get back home, but you cannot go back and recapture that same lighting, foliage, clouds and mood.
