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.

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.

My e-mail inbox often contains some photo related promo piece, most of which I have learned are only worth ignoring and trashing. But Workhouse Publicity sent me a piece about Photographers Limited Editions describing it as a showcase for some of the world's best contemporary shooters and the press release was about featuring the work of Howard Schartz currently. However I recognized a lot of the names of photographers that I know are published in the slickest media today, so I decided to take a look, and was entranced in this website gallery for some time looking at the collection of images on display.

Recently I have reported on products I have tested and used. If a product works for me I will recommend it as I assume if I can make it work, others should also be able to do so. This may involve hardware and software used together, one being supported by the other, and may include additional products designed to be used with the primary product. Some of these products are designed to be proprietary, to work only with the recommended additions as advertised. I am usually strict and limited about my recommendations and do not include options for substitutions.

When I began this blog the last thing I had in mind was commenting on other blogs, but in ZDnet.com’s Mary-Jo Foley blog, her plea to Microsoft programmers to NOT make the next Windows too Mac-like, had me laughing and fuming at the same time. (http://blogs.zdnet.com/microsoft/?p=1747&tag=nl.e539) Especially today after reading in the New York Times David Pogue page with a section on Maintaining The Mac, (http://www.nytimes.com/2008/12/04/technology/personaltech/04askk-002.htm...) which amounted to almost nothing unless one is paranoid by disposition. I switched from Windows to Apple Mac almost a decade ago and have had virtually no maintenance that needed to be done in that period of intense computer work, compared to it being an almost constant chore before with Windows. But what really got me was what Mary-Jo put in her wish list “fewer UAC prompts, simpler backup and restore, better peripheral handling” which are all current included features of the Apple OS!

Logically, some would think because digital cameras are now so popular and have replaced the use of film to a great extent, that film scanning would decline proportionally. But the reality is that there are enormous personal collections of film images people have created over much of the last century. Most realize these film images will decay and deteriorate in time, but the history they tell should be preserved if for no other reason than preserving the history of their making.

Usually I do not write about things I read in others writing I receive in RSS feeds. But a blooming new creativity interest using flatbed scanners is something I could not resist. It is called scanography, using a flatbed scanner as if it were a digital camera to take digital pictures of 3D objects. So considering a lot of photographers have flatbed scanners these days, how about getting more use out of it to create photographs when it is too cold and nasty to go and shoot your camera outdoors? You can easily take a look at what others are doing with their scanners by visiting a web site all about it at: http://www.scannography.org. In this new web site you will find there is a Scannography.org .PDF file you can download that provides a detailed look at the work of many people using scanners as cameras with lots of fascinating examples of their images.

Before digital I spent a lot of time in my darkroom often experimenting, trying different kinds of chemistry, modified techniques, something old, something new, and often learning just how limited the silver halide photographic process is. Since Photoshop and image editing I found digital photography to be pliable to an almost boundless extent. Of course the abandon you have to change the values of pixels has a different kind of limit by producing images that have no redeeming qualities what so ever. From that experience of course one should learn just because you can do something does not mean you should.

What does the quoted title of this blog mean to you? Does it mean you as a photographer don’t really want to do photographs digitally, but do? Does it mean photographers using digital photography don’t understand what digital means? Or does it mean you need to buy a product that makes digital photography look like film photography?
