So I've been doing most if not all of my photography over the last 7 years without using a flash. I like ambient light and ... I dislike it when a flash has obviously been used to get a picture.
So my question is: Do you have any recommendations I can start out with? What conditions would typically require which settings?
Note that I would like to use it for general photography because I do very little portraiture.
Excellent website I've recently stumbled across. Heavily portrait-biased but what's the difference between a person and a 'thing'? http://neilvn.com/tangents/flash-photography-techniques/natural-looking-flash/
Note in the 2nd example the subject in the foreground is entirely
lit by the flash as he's had to have a relatively fast shutter speed (to keep the colour in the stained glass windows) and without the flash the foreground subject would have almost been a silhouette. He's made the flash look natural by a) bouncing it off a wall behind him, and b) Correcting white balance of foreground (and possibly background) in post.
This other page deals with mixing flash and ambient light, which seems to be exactly the sort of thing you want - particularly the first example.http://neilvn.com/tangents/flash-photography-techniques/flash-and-ambient-light/
The pages are part of a series and I'd suggest you read them all, plus the Stobist 101 & 102 series. Even if you're not using flash in the way that they do you'll be wanting to steal some of their ideas.
