The filter does exactly what it promises, I made pictures with auto white balance, and this filter the difference is astonishing. Further still film filter going to get for a slightly warmer color portrait also are easy to assemble. There are always photographers I say working in RAW format and can later edit everything but it's easier. The only drawback, the filters are only in a paper envelope, better would be a film cover here, as I know it from my Nikon flash forth.
