The 6.5 x 6.5" Solid Color Red 2 Filter from Hitech allows you to add color or enhance the contrast of your image. This filter is made to the highest technical standard that delivers a filter that can be used with confidence. Tolerances are manufactured to such a high degree that similar filters can be exchanged from day-to-day without any trace of difference in the color. Hitech filters are 1.5 mm thick and do not bend like traditional resin filters. The Grade 2 version of this filter brings an even stronger sense of red to the image. It is great for special effects shots.
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.
