ISF Chief Joel Silver Shares Proper Calibration Tips

Find out why Silver says calibration is more important than the component itself.

04.26.2007 — “When you watch 35mm film, are you watching moving pictures?”

After a slight pause and a smile, the man dressed in black answers his own question. “No,” he says, as he stands next to three large Stewart Filmscreen products.

That’s how Joel Silver, founder and president of the Imaging Science Foundation (ISF), starts the second day of his two-day training seminar at the Spring Electronic House Expo (EHX).

It’s typical Silver style to mix some light-hearted fun with his curriculum of technology-based standards and practices to a room full of custom-installation professionals eager to learn how to properly install and calibrate state-of-the-art video systems.

Silver’s mix of one-liners and tech-heavy topics helps his students and followers keep up with the intensive two-day program without ending up cross-eyed from trying to absorb everything thrown at them.

Over the course of the two-day seminar, which was featured as part of the week-long EHX education schedule, Silver covers everything from the basic principles developed for television when it was first introduced to techniques for calibrating white, black and color levels on a modern video system, and how to bill for and explain the services provided.

In a day full of questions, Silver answers why an installer needs to calibrate a video system by quoting a long-time follower. “Calibration of a device is more important than the technology inside it [the video product],” he says, attributing ISF alum Mike Wood.

By mid-afternoon, the fast-moving seminar arrives upon a subject that Silver emphasizes as arguably the most important and the most misunderstood by consumers and even installers. The topic he explains is shapes or aspect ratios, and according to Silver it’s a convoluted topic that unfortunately can only be addressed correctly in one way.

“I go with front projection to get rid of the blacks because you have to fit your screen to the movie,” he says. “You have to educate your clients on aspect ratios and you have to get use to people bitching about black bars. [From the installer perspective,] I think it’s the toughest material you have to teach.”

Transitioning onto the next point of his teachings, Silver refers to ground-roots marketing initiatives that have served to fuel the custom industry’s rapid growth by pointing out that service is all about perception. It’s during this time that he lays out a typical scenario where a client receives a nicely installed system and shows it off to his friend. The friend, he says, goes out and buys the same system, which alienates the first client because he now thinks the friend’s system “looks better.”

Silver says an installer can avoid this situation by documenting everything from the system’s color and brightness measurements down to its smallest details. “The single most important thing for a referral-based business is to document peak light output and to take the bulb’s numbers down,” he points out. “When light output dips below 30 percent, replace the bulb.”

Closing the day out, Silver provides some hands-on time for his students to calibrate color levels with a variety of LCD and plasma displays that line the sidewalls. The class ends with Silver demonstrating the differences when using the right tools. In this case, he uses a variety of equipment from Sencore to show why front projection requires different testing apparatus than flat-panel or rear-projection televisions.

Summing up the seminar’s effectiveness, Al Sheppard, president of Winter Park, Fla.-based Smart Space Living, LLC, evaluates Silver by noting how well the industry icon communicates his message. “I think there’s a lot of information being conveyed,” says Sheppard. “Joel’s got a lot of information and his straight-forward manner makes it interesting and thorough. Sometimes these classes are overdone, but that hasn’t been the case with this class.”
5 Tips for Proper Calibration

Let products warm up before starting any measurement and calibration procedures.
Take pre-calibration measurements to establish a baseline of performance.
Calibrate primary colors before tackling secondary colors.
If possible, light the seating area and not the screen area of a room to maintain contrast.
Don’t conform to preconceived standards; start a dialog with your client to determine what their preferred seating distance is to ensure their happiness.

Unlimited

最近發現一個問題...事源喺楊千嬅一只專輯"Unlimited" ,林夕曾經喺叱咤個頒獎禮上面提及到"Unlimited" 喺一張好高質素嘅專輯,但係好明顯大路嘅樂迷唔喺好中意專輯裏面嘅唯一派臺歌"我的生存之道". 

呢個就喺矛盾喇,雖然可能市面上大多數目嘅專輯裏面;好多歌會好听過派臺果首,例如Eason嘅"葡萄成熟時"受歡迎過"夕陽無限好",等等.

重點係有人提出過楊千嬅最近嘅專輯都唔好听...點解會甘嘅呢? 

有一個高手一針見血地指出咗原因,多數受歡迎嘅歌曲都會有K味,意思喺大多數人都會聼完之後就曉唱喇,Karaok嘅點播率就自然高啦... 

的確"Unlimited"嘅內涵喺好成熟嘅,應該講去到一個更高嘅level,只不過喺我無feeling...因爲我還停留在聼K歌嘅階段... 

如果要聼有K味嘅歌呢...Justin同Janice絕對OK,睇下宜家D人反應就知道啦! 

我用咗幾日去review翻好多呢方面嘅資料,聼咗好多歌,當然唔喺D咩hit歌啦,Edmond就喺一個其中相似嘅例子,市場需要K歌..但係樂壇係需要好歌..做歌手既目的係將自己既感受帶比每個觀眾... 

如果原地搭步,隻隻k歌,咁香港樂壇死得喇...可能對聽慣K歌的人要需時間細味... 

我承認我自己喺一個乜歌都聼嘅人,以前會覺得自己懂得聼歌,知道如何去欣賞一首歌...可能自細就跟阿爸聼音響嘅關係,當然喺指軟件啦,嘗試唔同嘅音響硬件,喺要付出好多Money嘅... 

啊,離咗題...我發現從前我聼歌,聼唔同嘅歌手,唔同嘅歌曲,但係同一種風格,其實自己的耳朵已經開始糜爛. 

歌手Grow up.我諗我自己都要喇...
