I use kodak portra 400 as my go-to film when a higher speed is needed. With winter approaching I will be taking more of my pictures indoors. I know portra is a very versatile film so I am looking for tips on exposure compensation without using filters in tungsten and fluorescent lighting.

I have found that +1 works very well for tungsten light, but I am curious to what other people do.

I have never shot in fluorescent before. How should I compensate for this type of light?
