This rather enigmatic movie title came to mind this week after engaging in both live and virtual e-mail conversation about the problem of “prints too dark” I have reported and commented on recently. It seems those most likely to have a knowledgeable understanding of the technical cause of this phenomenon, and any possible solutions are the least likely to want to admit the problem even exists. And if photographer computer users are obtaining too dark prints it is because they are at fault: either their home/office environment in which they do their photo processing on a computer is non-standard or their illumination for print viewing is inadequate.

I posted a Blog on December 16, 2010 titled What Is Display Calibration & Profiling? There were a number of comments posted and several were questions. So I asked our blog expert if there was any practical way for me to obtain copies of the comments and the address of the comment source. The answer was no.

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.

The “prints too dark” problem inadvertently involves almost every aspect of computer image processing, displays, printers and their drivers, color management, and of course image editing. Yet it is just a single issue of prints that don’t match the screen in density/brightness. The explanation of why the problem seems insoluble is that all of these separate but involved functions are the domains of companies which compete with one another in a marketplace that discourages standards. For instance the driver interface for each brand of printer is different, as are the on-screen controls of each brand of LCD display. And of course the people who run these companies and the technical people who design the products do not see reality from the same perspective as users, who of course are an even more diverse population.

It is what you see on-screen that allows you to perceptually adjust and change a digital photograph. I have said what I believe to be true, if you can’t see it, you cannot control it. So I have thought of all things computer, the display is the most important part for digital photographers. However, some think I make too much of it, but then the display gets me more questions in my mail than any other subject.

I recently submitted my report on how to avoid “prints too dark”, but I am still doing research trying to find affordable, even inexpensive, LCD displays that can used that can be adjusted for brightness to provide print density matching. There are $1,000 plus solutions that are easy to implement and effective, but as budgets are getting smaller, obtaining an effective reliable digital photography experience with a computer virtually disappears if the price is affordable. However looking at one low coat LCD display after another I noticed a new breed of displays that are specifically enabled to support 3D gaming. And today I received my copy of Computer Graphics World and the lead article is about 3D graphics including gaming, with the inside cover ad touting these new 3D LCD displays.

No my sex-life has not improved. I haven’t been looking for a new squeeze. But I have been looking for an inexpensive LCD display that will work for digital photographers. Actually I discovered it among numerous models LG Electronics has listed on its web site awhile ago. But a request to LGE for a loan to review it for Shutterbug was denied because it is a 2008 model that is not being offered in the 2009 product lineup.
