Ted, a red filter will give you a portrait of a ghost instead of a living human. With an orange filter, maybe a zombie. :-) White lips aren't attractive.(posted 8340 days ago)I use a light yellow filter or a light green filter for portraits or for everyday photography. I love the tonality. But that depends of course on the light I'm shooting in.
Before you take the photos you should think about how you want the results to be like. Then check the possibilities, if you need a filter to correct the light, if you want a softfilter and so on. It's good to plan how you're going to develop the film, the Asa seetings and so on...
