Have been a long time Velvia user and my wife used Kodak Supra. This was discontinued and switched to Fuji
Superia 400 has been our basic wedding and portrait film. It is economical, has good speed with very fine grain. It's wide exposure latitude lets it capture detail in white wedding dresses and black tuxedos. It has accurate color, medium contrast, and mediium saturation which compliments most skin tones and hides blemishes. It is similar to the more expensive professional NPH films that we used in the past.
I standardized on Fujifilm years ago and on Superia ISo 400 when it was introduced. Sticking with one ISO speed allowed me to fully explore the range of the film. As noted, the only concern I ever had with this film was the possibility of getting reddish skin tones when shooting candid portraits using flash.
