Hi Paul. I have used Ansco 47 quite a lot and have considered it one of my main developers when processing sheet film intended for platinum printing. It is a very basic Metol Hydroquinone developer and is designed to be long lasting and clean. It tends to build a lot of density so you have to be careful not to over process. It makes negs with sparkling whites that hold up to platinum printing. Unless you are into push processing or want dense negs, I wouldn't use it for regular roll film.
