For the technically astute, here is an impressive interview by Murideo (calibration instrument provider) with the developer of the MediaLight line of LED bias lights: (1:27:17 Video) The interview offers many great PowerPoint slides of relevant graphs and examples of human perception in this...

How Viewing Environment Conditions Can Corrupt Or Enhance Your Calibration- Updated Fundamentally, all of motion imaging technology is based upon human visual perception. The world's most perfect calibration instrument cannot fully duplicate or measure how our brain interprets what our eyes...

In your experience working with Sony, how alert are they to human perceptual factors relating to viewing environment principles and eye strain (especially regarding the "C" model)? I assume these panels will operate at significantly higher brightness than a typical projection system. Best...

Some displays offer individual settings for each video input used. Others have global settings values for all the vide inputs. In other words, the settings selected for one input would be repeated for all the other inputs. Powering off an external video source device would not change the...

I would love to receive this epic Blu-ray Disc edition! Thanks.

FIBBR Pure2 Fiber Optic HDMI Video Cable Review I was given the opportunity to evaluate a recent video interconnect technology product that promises to provide superior signal transfer for the latest 4K UHD HDR programming. My system has yet to be upgraded for 4K but I want to be familiar with...

We shall see just how successfully these manufacturers and content providers implement this promising initiative. This is nothing new. The professional display calibration community has been enabling this option for discriminating cinephiles at home for decades. As the presumptive "godfather"...

Screen size is determined primarily relative to the light ouput of the projector. A larger screen requires more luminance "horsepower" from the projector to reach recommended minimum image brightness. Keep in mind that light output diminishes as the lamp ages, even laser-illuminated phosphor...

Here's a bit of a short cut: What color do you perceive is the center portion of these crossed objects? The one on the left should look blue-ish. The one on the right should look yellow-ish. They are actually identical. Go here for a demonstration of why they appear to be different...

Gregg also makes less regular trips to Colorado when several calibration requests can be bundled together.

Proof of how a colored surround distorts the viewer's perception of the screen image is found in some fascinating online graphical demonstrations from a university in the UK. These "Colour Perception Illusions" come with a "mask opacity" slider that allows gradual desaturation of the colored...

News about Gregg Loewen: THX has terminated their THX Display Calibrator Certification training program! Gregg Loewen, of Professional Video Alliance (PVA), was their international instructor since the inception of the program. He is now offering a newly formatted, continually updated...

There are always exceptions, but most humans are susceptible to eye strain and viewing fatigue when watching a bright object in darkness. It's similar to driving into oncoming traffic at night on the highway. That's a big reason for forested medians on interstates to block this from the opposite...

Philips' "Ambilight" feature started the fad way back then. They pulled out of the US market with diplays after a few years, but continued with "Ambilight" models is the European market to this day. No other TV manufacturer has offered such a feature, but some after-market accessories have...

Not soon enough! It's been about 18 years already and companies are still promoting the practice and providing solutions for implementing it as an accessory.

Suitable for full IMAX. I would be thrilled just to have 1080p/12 bit/HDR/WCG for TV and 2160p/12 bit/HDR/WCG for projection. Best regards and beautiful pictures, G. Alan Brown, President CinemaQuest, Inc. SMPTE, Professional Video Alliance, THX, ISF, Lion AV Consultants "Advancing the art...

Regarding Colored Lights Behind TVs Everyone is entitled to their own sense of priorities. Surrounding a TV with colored lights or wall perceptually subtracts that color from the picture in varying degrees. The motion imaging industry is guided by standards and recommended practices in order to...

A new tool for owners of 4K/UHD/HDR televisions and projectors has been announced! I have been collaborating with Ryan Masciola, of Diversified Video Solutions, LLC., producer of the UHD/HDR10 display calibration program, for the substantial revision of his suite of test patterns and a soon...

Doug Weil (ISF & THX, of Lion AV Consultants) may be able to include Wichita on his next tour. He recently toured through KS, CO, OK, TX, etc. Contact: [email protected]

Gregg services states across the nation, not just one coast. He actually lives in Maine. Chad also services much more than just states on one coast.

All video displays can be calibrated to one degree or another. A video projection system is just one video display type. The Imaging Science Foundation is an educational and consulting service provider. Video display calibration predates the ISF and continues independently of it. "ISF...
