The HD Soft Gold 3 Filter from Hitech has been developed to negate the ultra sharp effects created by today's super sharp HD technology. This filter will provide enhanced flesh tones while having little effect on contrast. It eliminates both the blueness of the image as well as minimizing facial imperfections and blemishes. This kind of diffusion filter will make your subject appear in a more flattering light. By achieving this, he will be more receptive to the portrait or interview. The strong grade 3 version of this filter is used when facial imperfections are pronounced. There is still no effect on contrast.
The Hitech filter system is made by Formatt - an English company that is renowned for its high manufacturing standards and consistency of quality. Their CR39 resin is manufactured in large sheets that are oven cured. Their exclusive Absorbing Cell Technology absorbs color as opposed to other filters that are coated. Once cured, they are sliced up to create individual filters. In this way, maximum consistency is maintained from filter to filter. This becomes crucial when you wish to change filters either mid shoot or from day to day.
