Mark, I have been using a #25 red filter with Fuji Neopan 1600 and 400 for a couple of years now, with a lot of my portraits, and I love the results. It does depend on the person's skin tone, and a lot of other factors. So, I usually take shots with and without the filter. I think it is worth a try.(posted 8324 days ago)chris
