I would guess the casual consumer when confronted with images displayed on computer screens probably assumes there is some color standard involved that regulates what red, blue or yellow should look like that governs the manufacture of these displays. But that is an incorrect assumption as all color reproduction devices are what the industry calls “device independent”. In other words it is a “free market” and a maker of display screens, as well as printers and scanners, in fact any device that reproduces color information, is not held to any standard in terms of the observed color reproduced as the result to the specific RGB computer data sent to or received from the device.

About a month ago I wrote a blog here about a new LED lamp made by Fobsun in China. And here is the essential information I had at the time: “I took interest in Fobsun because they sent me a news item about a downlight they make that has a 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.”

From my experience from a lifetime of photography I have learned better than a new lens, or camera, any gadget or gizmo the best resource for getting better pictures and enjoying making photographs is information, understanding the tools I already have and how they work. The only way to get out of a camera all that it can reproduce is to know how it works, the only sure and easy way to control the photographic process to reproduce the images that you imagine and hope for is to understand how the photographic process functions.

I just received one of many statements from photographers that the current digital technology is complex and confusing, so it’s hard to understand. I could assume from that many think digital follows what analog film photography established. But that also assumes that the photographic process was understood as it has been for over a century, but sadly both assumptions are mixed up by many mythical and fantastic ideas and beliefs that have confused many if not most for as long as the 50 some years I’ve been a photographer. And it has not been helped by an industry and technology that now uses terms like resolution, which on film meant how fine the detail was resolved sharply, to its digital meaning that defines the size of an image in pixels.

Although “free market” self-governance may seem to smack of a political issue, its application affecting technology business has had an affect that has been to no one’s advantage. What I am alluding to is a well known example, the old fight for dominance between Sony Beta and VHS and the recent similar competition with Blu-Ray’s win for HD-DVD media dominance. In the Beta/VHS outcome the lower cost but inferior recording technology won and users, as well as VCR business suffered as a result. it is too early to tell if Blu-Ray dominance will be a loss for all sides, consumers and producers alike, but history forgotten has a habit of repeating itself.

I don’t know about you, but I often relied on sunglasses, “shades” when I was driving west in the afternoon. They helped a lot to see the road clearly reducing the extraneous direct light from the sun obscuring my view. The same idea applies to your LCD display. If you keep it shaded from extraneous light in the room where your computer is set-up you will see the image on screen more clearly and free from different and conflicting strays of light. Even in my north-facing room that’s dedicated as my lab, even with special Fobsun LED lamps for my environment lighting, and with a hood protecting the screen, my new Dell Ultrasharp U2410 has a cleaner, brighter screen image now that it has shades.

In the July issue of Shutterbug my answer in Digital Help to Rich Zahren’s question about HD format slide show authoring elicited a good number of suggestions from readers. One involved maybe the easiest, cheapest to implement and best ways to present a slideshow using a large LCD HD TV that are now so popular. Set up your LCD HD TV as a display for your computer:


“It's very easy to use your personal computer to present digital photo "slide shows" on HDTVs. Connect a 15-pin VGA cable from the computer's "monitor" connector to the HDTV's "PC Input". Make sure you've set the computer's Display Properties settings to match your TV's resolution (1920 x 1080 for full-HD 1080p sets; 1280 x 720 for 720p TVs). Most computers made in the last 10 years can be set to these resolution values, including some laptops. (If your TV lacks a "PC Input", buy a cheap computer video card with a DVI output connector, and use a DVI-to-HDMI cable to connect the computer to one of the TV's HDMI inputs.) Then run one of the many free photo-viewing programs on the computer (they're packaged free with most cameras, or can be downloaded on the Internet). The full-HD results can be spectacular--much better than trying to view the photos via a DVD player or a card reader connected directly to the TV.”

Almost every paper and web photo publication has reported on Canon’s newest G-11 model high performance P&S camera. Some have noted that this new model has a lower megapixel count of 10 MPX, compared to the 14.7 megapixel G-10, that is still featured for sale on the Canon web site. One pundit even quoted without naming his source at Canon “They have also changed up the sensor, keeping it the same size, but making the pixels bigger. The result is a lower 10-megapixel resolution, but they claim the trade-off is better image-quality, especially in low-light situations. A Canon rep mentioned that it's because the G-11 is focused on providing the best quality in the form of a still image.”

I am thankful for three days of gentle rain here in southern California ending a wildfire season that has been one of the worst.

Wouldn’t you know as soon as I admit a typo mistake about 8 gigs of RAM in a Mac Mini in the July issue Digital Help, the following week Apple Announces an all new Mac Mini that will allow just that much RAM to be installed. No , I did not know about the new Mini, I did make a mistake. Ahead of the times? Well, that is usual for me, but I did not see a new Mini coming in my psyche.
