First to bring you up to date. Since my workflow article ran in the December issue of Shutterbug, word has gotten around and back to me providing lots of information for a better picture of the problem. I have done more testing, which concluded even for a well color managed system like my own with LCD’s there is some darkening in print results because of color correcting and editing with an LCD with screen brightness set exactly at a luminance of 120.0 CD/m2. I confirmed this by opening some finished scanned image in Photoshop, files done when I had CRT monitors installed and then stored on CD’s that have been printed in the past. These image files look fine in terms of density on my LCD screen, and print as they did in the past achieving the same print density the screen appearance would suggest to expect. I have to assume the reason is that the image brightness midpoint setting in Levels made using a CRT monitor with a white point luminance of 90.0 CD/m2 (which was not changed for this current and test and printing), and the correct brightness of the print is because the brightness range of the CRT closely matched the density range of a high quality inkjet print.

In just a few days after the November Shutterbug hit the streets, I have received 3 questions reacting to the following comment I made in Digital Help, "That you are working with Microsoft Vista, considering it does not support using a color managed display, is also curious." This is not the first time I have said as much about Microsoft Windows Vista since I first reported on the operating system in 2007.

Maybe it’s just me, my peculiar life and perspective, but I was just reminded by an article about jazz in the New York Times(Home Life With Mikes: A Jazz History by Nate Chinen, February 17, 2009) that included a part of W. Eugene Smith’s life defining a connection between music and a photographer. I suspect the connection is enhanced in my mind in part because in high school my ambition was to be in music as a singer, and I participated in several choral groups as well as took voice lessons for a couple of years. After high school four years in the military intervened and provided the opportunity to become interested and get into photography. I was not sorry I got detoured because having a deep voice myself, and baritones became eclipsed in those years by singers like Johnny Rey and his pop song “Cry”. Regardless, even though I embraced photography completely, I still enjoy music, especially jazz.

I have been preoccupied now and for some time by the challenge of defining an affordable platform for inputting digital photographs and then printing them with matched color and density to an LCD display image. There are quite a few LCD display choices at $1,500 and up which support both color and density print matching with a color managed workflow. But an affordable consumer LCD display ($300) has been the elusive goal of a lot of searching. And from what I have heard from industry insiders is that the major display manufacturers in the immediate future are cutting back on their support for high-end, niche pro-graphics market displays.

I always like to work with the newest and best, but the reality of my budget is always the deciding factor. So I upgrade a bit less often than I would like. This time I had no say in the matter. A freak accident wrecked one of my Mac Mini’s and its external hard drive with backup in one fell swoop. Panic time and calls to Apple for help. Even though not responsible Apple was generous in helping with the recovery, although I had to spend some money too, plus invest a lot of work time. But the recovery is almost complete.

Human vision is incredibly adaptive so you can see in bright sunlight on a ski-slope during mid-day and at night on the highway to drive home. But this adaptability being essentially automatic and subliminal can be a disadvantage because your perception of small brightness differences between screen and print is not obvious until the print becomes a physical reality that makes it apparent.

Photography is approximately a 140 year old technology, but among the younger set using the latest cell phone models photography is often an integral part of this newest communication mode, take a picture with the phone and send it to someone else. When I first began doing photography almost 60 years ago it was a lot more of a challenge to participate than pushing a button or two, there weren’t even any reliable light meters then to use to calculate the film exposure, plus the many other things that all had to be done individually like focusing the lens on the subject, setting the aperture relative to the shutter speed, all relative to the ASA speed and type of film you were using. In other words photography in the 1950’s was a demanding technology to perform and of necessity had to be a concentrated single-minded experience.

The last two days have been a bleary-eyed ordeal reading as many forum posts as I could on “prints too dark” from a Google search on that phrase, which obtains almost 2 million results. What I was looking for was as complete a picture as possible why people trying to make photo prints were getting unacceptably dark print output. I didn’t get very far into the almost 2 million results before my eyes gave out reading the forum posts, but I did find that a lot of users have discovered the cause of dark prints is an LCD display that is too bright. But confusion reigns when it comes to how to fix the problem, very often involving color management and the idea of using Photoshop’s “soft proofing”. Some forum gurus have been recommending adjusting the display brightness to match the print output, and actually that practical philosophy was used before there was such a thing as Color Management, but it largely precludes color matching using CM and a calibrated and profiled display, if in reality an LCD display can be reduced in brightness to actually match the range of print densities or the CRT monitors of the past. Some users found that instead of having their photo editing application control color, select having the printer driver control color, which with some printer drivers does provide an output print density adjustment and yields satisfactory print brightness results, but the downside is that some printer drivers will automatically adjust print density and others don’t, as well as color matching with what you see on-screen is not usually supported.

There was a time in my life when Will Rogers often stated, “I know only what I read in the newspapers.” had a resonance with people. No one has taken his place in American culture and spoken for what can be learned from TV, or what they read on-line. Maybe it is just changing too fast to make any sense. It sure is when it comes to managing color on a computer system. When that began to become popular, to buy a sensor and software to measure and color manage the differences between a computer monitor and a color printer, it worked for a few of us pretty well. I had been reading, studying and experimenting with color management for years hoping it would finally be realized for most of us with computers and then Adobe released Photoshop 5.0/5.5 and it was then a real possibility for everyone.

I was just reminded by a list of currently established luminaries in the photography world, that what I knew and the names and images that inspired me during my early, formative years as a photographer are no longer current, replaced by names and images that are unfamiliar and don’t have an iconic role in the photography niche of contemporary culture. What has changed is not the quality of photographic work being done, but that there is now a greater volume of public information in a digitized cultural venue that is huge and rapidly evolving. Today’s photographic talent is simply lost in a deluge of image media of every kind and description. Magazines, newspapers and books still exist but even TV has been displaced partly by the internet and YouTube. How different it is when a movie star, Selma Hayek on a mission to Africa assisting in a campaign to reduce the high death rate of infants, is covered by ABC News in scene where she breast feeding a baby of a local woman who had gone dry. This most humane gesture caught on video has now gone “viral” on the internet. I find nothing to criticize, but in such an instantaneous global village of images, that will soon fade with the next “viral” pop news event, can any image attain a lasting iconic status, much less the person behind the camera who made the image?

The other day I received an e-mail press news release about a new handheld light meter. I had not seen any news of handheld light meters in some time, so of course I read it. In style and content it was much like what I probably read twenty years ago. But what struck me strangely, now that virtually all cameras are digital, is the fact a digital camera is really just a light measuring device that records the light readings of millions of pixel sites and records them in an image file. Of course that does not preclude the value of a narrow angle spot or an incident light meter, they are useful in measuring the light on and from a subject to make an informed decision on making a photographic exposure with digital or on film.

I don’t think my town is all that much different from a lot of places in America today. Not that many years ago there were three locally owned and operated camera stores, and today there are none. The only local selection of camera’s and photo gear is Walmart has to sell. Yet in the current economic situation the pundits and politicians talk about small business as the source of jobs and economic recovery, while I see ever more empty commercial spaces where another locally owned and operated business has disappeared; and the businesses that remain are big-box stores and corporate fast food, drug and office and home supply outlets. Maybe they (McDonalds and Best Buy) are a part of the businesses the media and Congress’ count as being “small”.

As I have written before, my holy grail is an affordable LCD display that supports digital photographic editing and printing. I just recently discovered one that has some essential attributes, and even bought one, and LGE L227WGT. A reader just commented he purchased a display he is pleased with that was quite affordable, an AOC Verfino 22 inch with LED backlight (http://us.aoc.com/lcd_monitors/v22). But even the added new feature of LED backlight, which has distinct advantages, still leaves the basic problems that can cause “prints too dark”, as well as the added expense costing as much or more than the LCD, a colorimeter and software to calibrate and profile the display.

It has always been my nature to find what works for me regardless of whether most everyone else is doing something different. Since 1975 I have purchased and driven Saab cars almost exclusively, and still drive a Saab. When I was a freelancer in the 60's my colleagues used Nikons and I preferred the Topcon 35mm SLR camera system. And if I were not already very invested in another brand I think I'd probably choose and buy a Sigma digital camera. Not just to be different than the herd, but the technology and thinking Sigma employs I believe has positive image quality performance advantages.
