18. s You find the list of the dealers internet website 17 Review and Comments Professor Harris Fogel The University of Art Philadelphia USA As a professor of photography and digital imaging I m keenly aware of and interested in solutions that help to solve color management problems And thus was interested in your product which took a new approach to the problem of setting an accurate white balance in digitally captured images Most approaches are based on the selection of neutral grey point similar to an 18 grey card It has certain drawbacks find that CBL took an interesting and unique approach to the problem which was to create a handheld test target that utilized a combination of neutral point and prism technology to achieve accurate readings This is a fresh approach to the problem and my test of your CBL Lens units resulted in a very accurate white balance with no colorcast for the final image When first encountered your product it didn t seem all that complicated a simple handheld plastic target with what seemed to a plastic cover But soon learned that each unit was hand calibrated and had an advanced and complicated inner coating system and that the design s plastic cover actually acted as prism a design so unique that CBL was granted a patent on it While there are other very competent solutions to setting an accurate white point when working with digital cameras the CBL L
