Join Joe Brady for an in-depth discussion in this video Optical brighteners and profiling remote printers, part of Advanced Color Workflows for Photographers.
…This section is somewhat of a sidebar to our printer profile and considerations.…The two topics are unrelated, but important to know about in any case.…Let's discuss optical brighteners first.…Optical brightening agents or OBAs are dyes that paper manufacturers add to…paper to make them look both whiter and brighter than the base paper itself.…This is a double edged sword for a handful of reasons.…The way OBAs work, is that they absorb UV light, and then some of…that energy is then transmitted as visible light in the blue wavelengths.…
Since blue makes paper look both brighter and whiter, this has an appeal for…certain types of images.…In my opinion, there are three main problems with the use of OBAs.…First, since they are a dyes that actually react to UV light, just like inks,…they fade with time and exposure to light, and this can happen fairly quickly if…the paper's exposed to bright daylight for extended periods of time.…The result is a color change back to the natural more yellow base of the paper.…
In this course, Joe Brady builds on his Color Management Fundamentals course, focusing on color-management issues of specific interest to photographers. After a review of digital-color concepts, the course explores creating color profiles for each device in the digital photography workflow, from monitor to printer, to camera. Joe demonstrates the tools and techniques behind color profiling, even covering tablets—ideal for photographers using iPads or Android tablets as wireless remote controls.
