Canon tells me that digitals can't pick up deep violets...

and deep blue violets (they turn a lighter blue). Has anyone had a different experience?

1. Generally mine handles colors pretty well.

Try adjusting your white balance, either at the time you take the picture or during processing.

Mine has a harder time with teal and fuschia than with deep violets.

2. There is no medium to record colors perfectly. Film had it's

shortcomings too. Kodachrome tended to oversaturate the warm end of the spectrum and some print films were overly sensitive to the UV end.

One thing I've noticed is that digital doesn't have the latitude that film does. I think the experts call it "dynamic range" or the ability to record detail in the shadows while retaining detail in the highlights. As a result I find myself dialing in about 2/3 stop underexposure and post processing to bring the shadows back.

3. It will be a sad day when Kodachrome is no longer made

Nowadays, Kodachrome is confined to a small global market of devotees who wouldn't settle for anything else. And before long, industry watchers say, Kodak might well stop serving that steadily shrinking niche as the 128-year-old photography pioneer bets its future on electronic imaging.

The digital revolution is undermining all varieties of film, even a storied one that garnered its share of spectacular images: the giant Hindenburg zeppelin dissolving in a red-orange fireball in 1936; Edmund Hillary's dreamy snapshot of his Sherpa climbing partner atop Everest in 1953; and, most iconic of all, Abraham Zapruder's 8-millimeter reel of President Kennedy's assassination in 1963.

4. My photo in the contest this month

was taken with a Canon and I think is pretty true.

5. I've had some violets...

be picked up, even some blue violets, and some get washed out; turning to pale blue or pink. I'm not sure how the camera makes the distinction of what's good enough.
It's hard for me to tell the exact shade of your beautiful flowers, since I am, of course, dependent on my monitor. They are blue violet but exactly which shade they were as you took the shot I can't know. I take your word that they look the same on your monitor as they did in person.

8. Purple Fringing

A common problem with digital cameras is solved with a combination of filters over the sensor, and algorithmic corrections in camera image processing. (the process of taking the camera's raw data and turning it into a file of a given protocol such as JPEG)

That, and the whole mechanism of Beyer pattern sensor filtering make certain things difficult.
Most sensors only know an approximate color of an area around six pixels or so. They really do a bang up job considering, but purple is a weakness.

Sigma camera sensors are a whole different beast, as are Fuji's Super CCD.

I happen to like Sigma best, with fuji a close second if I didnt use that serious sharpness, and one color reading per pixel abliity to bring out the most subtle color gradiations that Sigma's Foveon chp provides.

9. That is just stunning! n/t

6. There are several workarounds with various

kinds of DSLR.
But as long as I do an individual white balance for the scene, I rarely have problems with my Sigma SD14.

7. I will keep that in mind when I don't see...

what I should be seeing.
