So this thread inspired a thought.

How can we use, control, and or mimic flare?

First, I'm not talking about the funky, special effects type flare, that causes shapes to scatter across a shot. I'm talking about the flare that provides a general change.

As an example, a generic pre-exposure for example seems to me to be a way of mimicking/adding a flare effect. It also seems to me that the second, after fix, developer bath sometimes used with Pyro might have a similar effect, but that's pure conjecture on my part

One example I experienced was when I bought my Nikkor 35mm f/2 lens and experimented with it in a high key studio set in place of the 50mm f/1.8. Instantly I had a very dreamy effect I wasn't planning on. I love that lens but pointing it at a large bright white background is a problem. So it seems t me that focal length plays a role.

I know many of us skip the use of lens hoods for various reasons even though we may know that flare may affect the shots.

So, IMO it seems a given that flare affects every shot, how can we/do you use or control flare?
