Bought for correction filter # 3401 and # 3202 Full RoscoSun 85 Blue or Blue Half

I use exclusively oa given filter from the set that came even several times, which is very convenient when loading multiple flashes. The filters are super and fulfill your purpose - namely the background in cool blue or warm yellow / orange to dive when one corrects the color temperature corresponding to the main subject. Among the effects filters in the set I can not say anything; the correction filter generate with correct set color temperature clean skin tones without green stitches etc.

Anyone googling my name is also my web page a blog post which describes with such filters work more comprehensively.
