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.

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.

Have you ever blown through a red light in your car, and as soon as you got through the intersection you realized what you had just done? Other than worrying about whether a cop saw what you did, you may have realized that your eyes saw the red light, but your mind did not register the perception and respond as usual so you could stop and wait for the light to change. What this kind of incident illustrates is that human vision is made up of two distinct functions, what our eyes see and what our mind perceives. As well as a third factor memory, which allows us to not pay conscious attention to everything familiar our eyes see in the course of daily activities, otherwise we would never get anything accomplished if we had to consciously deal with everything in our vision familiar or not.

For too long there have been few LCD displays available that fully support a digital photographic color managed workflow. Now LaCie has added another, their 324i with desirable specifications in a P-IPS 10-bit 24 inch LCD display. The screen image should be sharp and detailed too with a 1920x1200 pixel resolution. Most important of course is its color range that is specified at 98% of Adobe RGB. But these days with ultra-lite and flimsy un-adjustable home-office LCD displays in the box stores, the LaCie 324i has a solid, full-featured stand and supports portrait orientation. Like any good, current LCD display the LaCie has a wide range of input connector options like Display Port, DVI and HDMI.,BR.
