I've been around my share of low-budget and big budget films for nearly seven years now and it always amazes me just how much goes into making a feature film. It's easy to see how and why actors, directors, writers, cinematographers and even editors get the lion's share of the credit when it comes to a film's ultimate success or failure, for their work is usually the most apparent, yet there are scores of individuals that are essential in bringing a film to life. While I could go on at length about gaffers, grips and even boom operators needing to get more praise for their hard work, I'm going to focus my attention, for now, on the post-production side of things.

Having worked on April Showers for well over a year straight, I've come to realize that even when a team of trained artisans and technicians are doing their best work, it often goes unseen, due to the end result resting in the hands of consumer electronics manufacturers who aren't communicating to the consumer the importance of proper calibration. Whether it's audio or video calibration, it's important to adjust and properly tune your HDTV or home theater, not only to get the most out of your investment and enjoyment, but also to support and honor those who've worked so hard to bring you a total entertainment experience.

This week marks the third week of color correction on April Showers, which is a film that was shot in native 4K and is being finished in both the 2K and 4K levels. While the raw 4K footage shot by my director of photography, Aaron Platt, is stunning, there is a lot of work that needs to be done before it's audience-ready, mainly in the coloring of each and every frame. With regard to 4K, since it's a digital image, a sort of algorithm or lut needs to be applied to even see an image. Once the lut is applied, an image appears, though it is usually dark, a bit washed out or otherwise dull. That's where having a good colorist comes into play. A colorist will go in, extract and enhance the frame and subsequently the scene's inner beauty, bringing it to life the way the cinematographer and the director intended. Another side of a colorist's job is to inject color and subsequently add emotion and feeling into a scene, using the initial frame as a jumping off point. When the colorist and director of photography are working together in harmony, the effects are staggering. There's no making up for a bad director of photography. Remember, garbage in, garbage out. The same is true for colorists. I'm fortunate to have two real pros at the stick on April Showers.
What makes this whole process a little hard to stomach is the fact that few will truly see what Aaron and my colorist Tracy Smith have been able to do, for few consumers know or understand much about video calibration. Manufacturers, especially those making HDTVs, set their displays for the brightest, sharpest possible image, as market research has shown that potential customers view brightness and sharpness as signs of quality. Truth be told, you can get brightness and sharpness from pretty much any display these days; it's color accuracy, especially in the primary colors, and black levels that you want to focus on. Out of the box, your new HDTV or flat panel display is wildly out of sorts, usually defaulting to a Dynamic or Vivid setting, which is about as far from accurate or industry standard as you can get. In these settings, a film may appear more vibrant and alive. However, it's usually at the expense of subtlety and inner detail. They say the devil is in the details, I choose to look at it as "the drama is in the details" and, until your set is calibrated, you're most assuredly robbing yourself of the drama.

However, calibration doesn't have to be a foreign language; in fact, even a novice can achieve some sort of acceptable video image with little effort that will be highly rewarding. There are discs, DVD and Blu-ray, which essentially walk you through the process, explaining every step along the way. A great disc to help guide you through the calibration process is the Digital Video Essentials disc, which is available on both DVD and Blu-ray. The Digital Video Essentials disc is about as robust as they come. With a little time and effort on the part of the consumer, it can yield spectacular results. Another great disc (one geared more toward the novice user, though I know plenty of videophiles who use it exclusively) is the HDTV Calibration Wizard by Monster Cable and ISF. The HDTV Calibration Wizard disc will have you up and running a bit faster than the Digital Video Essentials disc will. Both will steer you towards the same end result, though if you want to go super in-depth, the DVE disc is going to be a bit better. If you don't want to mess about with added discs, some displays can show color bars and/or test patterns right from their menus and you can dial in your image by "eye," which is not ideal, but better than nothing. If you want to go for broke, you can hire a video calibration specialist and he or she will come to your house and do it for you for a small fee. If you are going to go this route, you'll want to make sure your calibrator is ISF-certified to ensure you're getting the most for your money. Sorry, an 18-year-old kid from Geek Squad isn't really going to get it done for you.

Regardless of how you choose to go about calibrating your HDTV, it's important that you do it, for not doing it is robbing you, along with the numerous artists charged with providing you with entertaining content, of the full picture. Trust me, the results won't be subtle and the time it takes pales in comparison to the enjoyment you'll get out of seeing your films and television shows properly. In some instances, it may even appear as if you're viewing them for the first time.

Calibration may be important to a movie maker expert but I wonder why should an average consumer would care? If my HDTV looks great in vivid mode right now, it looks great. End of story.

First off - VIVID MODE (not to be confused with a Vivid DVD which is something completely different) will burn your set out quickly.

Secondly - you wont get the most contrast or color as the film maker or TV producer/director intended.

HDTVs are designed to look good in sodium light big-box stores. That means you have to like the way a set looks when lined up with 3 dozen of them on a wall. The human eye likes blue so they push blue. That doesn't mean that it is the way you should watch your set at home where your lighting conditions are MUCH better...

I hope this helps coming from an ISF calibration school drop out!!! :)

I am not sure I understand this statement:

"If you want to go for broke, you can hire a video calibration specialist and he or she will come to your house and do it for you for a small fee."

Are you saying that ISF is expensive (go for broke), or not (small fee)?

As a lover of perfect images I agree with the concept of having a display device properly set, the question is WHO SHOULD do it?

After over almost two decades of paying for ISF services on all of my TVs and projectors (NTSC and HDTV) I consider that in 2009 it is about time one should be able to buy ANY HDTV with properly calibrated settings. One could further "adjust" the settings if needed (with a DVD or not) for the room lighting or for personal preference, but the set should be able to correctly reproduce the input image.

Additionally, a consumer has the right for the devices that playback or tune the source image to be also properly calibrated, not to mention the original image from broadcast, cable, satellite, FioS, IPTV, or pre-recorded media.

In other words, manufacturers can still “push” whatever setting they want to make the floor sample TV more appealing at the store when competing with dozens of TVs and fluorescent lighting, but the TVs that are actually sold to consumers MUST be properly set, and the dealer must know which is which. A new car should not need a tune up the minute is taken from the dealer; a new toaster should not need adjustment by an expert technician in order to burn the bread slices properly.

Having manufacturers not delivering properly calibrated sets created opportunities for ISF services, ISF training, ISF equipment, calibration discs, etc. and consumers are footing the bill of those expenses above and beyond the TV price, or end up viewing (many times unknowingly) an incorrect image. This should not have been allowed now after 10 years of HDTV in the market, and 2 years of Blu-ray.

From another view, an ISF professional calibration (from close to $300 for a single input, which usually is not enough) compared to what people actually pay for an HDTV itself (now many good sets under $1000) is becoming economically uphill as relative justification.

The talks of "requiring" calibration become further unreasonable in relative terms as the price of good TV sets go further down regardless how well they perform. Imagine buying a car for $15K and be recommended by the dealer to pay an additional third ($5K) for a tune up right after the car is purchased for it to perform properly “for what it was designed to do”.

For decades I was a supporter of investing in professional calibration in pursue of the best-possible picture because some TV sets could benefit considerably from the results, even when some TV owners prefer to further tweak the apparently dull ISF image after paying hundreds of dollars for it, but it is time for this to be a manufacturer’s responsibility to TV owners (not just for the sets for showrooms).

This personal view does not represent the view of any entity to which I am associated with.
