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.

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.

Three generations ago when I was a public school student Charles Dickens “Ye Olde Curiosity Shoppe” was one of his novels that was required reading. And in those days a young pupil’s curiosity was encouraged by teachers. Today I think if a student is too curious it may be reason to be prescribed Ritalin; our schools are not preparing young minds to be critical thinkers, but passive, obedient worker bees for corporate employment at some mindless task.

In my last post I mentioned that I had just purchased a Sigma DP1s that has just been released to the market. Don Ellis informed me that Version 5.6 of Adobe Camera Raw, I had not yet installed, had support for this odd camera with a Foveon 3 sensor chip - that’s fast and indicates Sigma’s use of the Foveon is catching on even in a camera design that is not the usual but with a fixed focal length lens. I tried using Adobe Camera Raw with some DP1s files and had to agree with Don Ellis, that like most 3rd party convertors, it falls short of the camera manufacturer’s software.. But that does not fully satisfy me so I went to Lasersoft and they were interested in providing support for the camera with their SilverFast DC and HDR, so I did what I could to help them with the project.

Last night after Thanksgiving I tuned into the news and caught an ad that really grabbed me. A local retailer was offering a major brand 8 megapixel point and shoot digital camera for $88, that’s $11 a megapixel! That really lowers the bar for anyone who wants a digital camera.

Not long ago I wrote a blog about the new Mac Mini just announced. The improvements Apple made were encouraging that the Mini would now be an even better mainstream option for computer users. But I had no plans to get one myself when I wrote that blog. But a bit of bad luck changed the situation. My relatively old office Mac Mini was knocked out of business by a “mini” external hard drive, one of several brands designed for convenience with the same lateral dimensions as a Mini and intended to sit under a Mac Mini. For some reason my little “mini” external hard drive failed and got very hot, and that damaged the Mac Mini sitting above. That was the second time I had one of these “mini” external hard drives involved in a problem with a Mac Mini. So a lesson finally learned. Convenience sometimes has a price. Oh! well, the new Mac Mini is a larger shape, so those old “mini” external hard drives are a thing of the past, and that will be a matter of deliberate choice in my case.

Some months ago a photographer posting in the Shutterbug Forum mentioned he had purchased a Kodak Kodachrome K3 IT-8 profiling target slide from B&H. I must confess I did not know Kodachrome IT-8 target slides existed only those made on Ektachrome for calibrating and profiling a scanner. I thought I had kept up with Kodak Color Management, but maybe the company never catalogued or made public the existence of Kodachrome IT-8 target slides, but on the internet in the Kodak FTP site I did find an Index File to enable using the Kodachrome K3 IT-8 I purchased from B&H, And then after borrowing a Color Management suite from X-Rite containing software to make input profiles I was able to use the Kodachrome IT-8 to profile my scanners and run some tests.

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?

I have to admit I borrowed this word from a MacWorld writer commenting on the tech bloggers of the day, it’s a good word. But I want to use it in reference to so many photographers for not researching and understanding the basics of digital technology based pixel imaging. It’s not that personal computer digital imaging is all that new, I’ve been working with it for 20 years. But the average photographer of the past, and used to film, have been led to believe it is just another kind of photography, much like film photography, and the same mind-set works as well with digital. Well it does for the camera companies, but not for their customers, because they are being encouraged to buy what they may not need and are not demanding more of what digital can provide, and they could use if available.

One of the most positive attributes of digital over film, the cost of film and processing disappears as an inhibitor to making photographs. I notice photo enthusiasts who write to me are taking large quantities of pictures at an occasion, especially recently since large memory cards have gotten very affordable. Like Joe Sixpack with his new Model XX dSLR shot 150 exposures of his 12 year old son's football game. So now what does he do, as he asks can he batch process all these files because he was told to set his camera on Raw to get the best quality images. And, color correcting and adjusting each image individually and manually is very time consuming whether using the software that came with the camera, or even if saved as a batch conversion to high-bit TIIF files and then color correcting and adjusting each image individually in a photo editor.

Fobsun is a Chinese manufacturer of LED lighting with a wide selection of products listed on their website www.fobsun.com. I took interest in Fobsun because they sent me a news item about a downlight they make that has standard lamp socket as used in America and white light output near 6500K color temperature. This lamp is also about as bright as a 40 watt incandescent lamp. To me its color temperature close to that of an LCD computer display and moderate brightness makes it an ideal candidate as an illumination source for environmental lighting where computer digital photography is done and prints are being made, in a light source matching the computer screen. It is a Fobsun Horizon Down Lights Adopting SMD LEDs, FLB-E27-90W-H, E27 base SMD bulb,38*160mm, 90LEDs,7W,100-260VAC, white color, 6000-6500k,630lm US $16.98
