Yes, digital technology change is like a merry-go-round. Everyone who participates in the technology is on board. But if you will notice watching a merry-go-round some of the “horses” go up while others go down and some have higher trajectories, for the older kids to ride. And, there are no parents sitting in the seats between the “horses”. Bill Gates and Steve Jobs are still in a race no one can win, but cheap in America always outsells good products, and nothing good ever comes inexpensively.

This old saying can be taken as a blessing or a curse, and its origins may be Yiddish or ancient Chinese, but if you are into digital photography the next few years may well be interesting times. Two pieces of news today are indicative of changes ahead. One is relative to my blog post recently about being connected. Apparently the FCC chairman Kevin Martin, a lightening rod of controversy is reported to have backed down on taking a Commission vote on a dubious proposal to auction vacant airwaves to provide a “free” broadband connection capability. Now of course making broadband internet connection more widely available everyone can afford is laudable on the outset; but some of the provisions and the way the proposal was worded in detail gives great pause that public benefit really was the goal of what Martin wanted the FCC to approve.

Personal introspection, thinking about who you are and why you are that way, has a bad name in America, it’s like “gazing at your belly button”. In other words American culture is outer directed and tends towards the practical. People should not waste time thinking about themselves, do something useful. But then, can you answer the question of why you like this and not that? Do you know why you enjoy taking pictures of some subjects and others don’t interest you. That is a part of you just as much as anything is, yet you take it for granted and give it little thought.

That old saw “an ounce of prevention is worth a pound of cure”, is applicable to the problem of bright LCD displays causing prints that are too dark, but at the moment that ounce is one ounce of gold. The ounce in this case is an LCD display that is not too bright, that can be adjusted, calibrated and profiled to match the range of values in a print. The one brand that currently has that capability as delivered is Eizo with their CG/CE ColorEdge displays. I’ll soon be receiving their least costly, the CG222w that has a list price just under $1,500 for test and review. I realize few of my readers want to spend that much, or can afford to, even for a display that does not cause the prints too dark problem.

The severity of and multiple factors that caused the recent economic crisis are a force of change. For a time fear has frozen activity economically among a lot of people at all levels, but that will thaw as people find they need to get along in their lives and the market for essentials remains substantial, even automobiles will pick up in sales as many will need to replace what they have out of necessity. And as most people get back to their lives, they will also return to the activities that are essential only to their enjoyment of life, including photography.

There are so many words which are available to express the idea of balance between things in nature and life. There are also many practical considerations, like if you want to use a swing in a playground, the other person on the far end of the swing must balance your weight if you want to use the swing enjoyably. If you are on a lake with a canoe on a camping trip, you take care loading the canoe so it sits in the water evenly from stem to stern if you want the canoe to be easy to paddle and control. If you have a truck you are careful loading the cargo area so the front part of load is a bit heavier than the rear so weight is not taken off the front wheels of the truck making it steer poorly. On and on, balance is an essential part of ideal functioning.

Today, November 23, in the New York Times, Circuits by David Pogue, he said “Pixels Are Like Cupcakes”. Cute, and a good analogy that a digital photo sensor chip is like a sheet that cupcakes are baked in, and that each cupcake holder is like an R, G, or B sensor site, but rather than cake dough it gathers light focused on it by the camera lens. Then he goes on to argue that the size of the cupcake or sensor site is determined by the overall physical size of the sensor chip and the number of megapixels it has. Further he argues that as the number of megapixels is increased for a given sensor area size, the smaller the size of each sensor must be, so it gathers less light and therefore functions less effectively.

In the old days of computer digital imaging those big heavy CRT monitors at least matched printers and printer paper in brightness, so no too dark prints. With today’s LCD displays most are now made as cheap as possible for home/office computing and are two to four times as bright as those old CRT monitors, which for most computing is is an advantage, but not for digital photographers who want to color anD brightness match screen and print.

From the e-mail and forum posts I have read Apple iMac photographer users are having the most difficulty with a too bright screen, and prints too dark. Thanks to one correspondent, Pat Marchitto who alerted me to Phil Corley’s web site
(http://www.philcorley.com/articles_68520.html) a solution has been found to lower the screen brightness to calibrate and profile for better print matching.

As the FCC is embattled between consumer advocates and media corporations for net neutrality, that access to broadband should not be controlled by private profit interests, the media itself is changing. Yes broadcast TV mostly delivered by cable, remains the dominant source of information and entertainment. But how people access the content is no longer so much with a traditional TV set in the living room, but with cell phones and most recently the iPad. But this popular media source is also rapidly shifting to access through the internet. TV programs, movies and music are now streamed live or downloaded over the internet, making broadband access by computers evermore important to many Americans.
