Thanks Brenda . . . I wouldn't mind whether you had seen this first or not . . . I'd be flattered if you had and was working of the idea. As you didn't, however, I'll settle for the concept that great minds think alike!! :)
Anyway - Thanks for commenting . . . now I have to check yours!

Clear and smooth or not, it would make a great abstract painting! Many thanks for your comments on my "Fire n Ice" mate. Getting that first BIP is something else, time to go celebrate with a cold beer.
Cheers mate!

___Thank you so much my good friend! I'm honored you added this to the favs and totally appreciate it. The catchlight has been mentioned and I will look into it next time . . . maybe posting both to get people to choose!
___By 'return in August' I was referring to a Pomona Bird Trade show where Pet stores and some people show up to buy directly from Bird breeders. My Bizz has yet to miss one of these shows. As a vendor . . . I can freely circulate amongst the other vendors and get photographs as well (have a great Toucan shot)! The bird in this shot was not mine but a fellow vendor's. Our next show is in August and already I have many birds ready to sell.
In short . . . You ROCK yourself!

I think that this is my favorite of the birds! I love the composition on this. The tight crop is outstanding. I love the dramatic colors and stripes surrounding his eye.
I'm not seeing the purple around the black stripes either.
I'm looking around for something to critique since this is a critiquer's corner photo... I think that the only thing I could find that I might change is the white flash (or catchlight) in the eye. I think that a catchlight is usually desirable in most photographs, but I feel like it might be a tad distracting in this photo.
All in all I really love it. Into my favorites it goes.
What do you mean about when you return in August?

Dear Doyle
I adore this close-up on the araparrot. It looks like a painting with lots of texture. A bit blurry, but it doesnŽt bother me at all:-)IŽve had so many nice, special experiences with these kinds of parrots. Great intelligent birds.
Best wishes,
Annemette

What a way with words - and an intensely impressive and inspirational image!
I really had to look hard at this to work it out - at first I thought it was a design on the bottom of a swimming pool or something, since the green at the top really looks like it's under water. Then I decided you had combined several images. It was only when I saw your comment with the larger image attached that I understood. Well perhaps I am being a bit slow this morning... I find the different textures across the image remarkable. Just one thing I'd consider changing - removing the bright spot from the eye.

You're the man! Awesome treatise and the fix (other than avoiding the problem) is possible in Elements 4 too. While I appreciate that . . . I still need to see it to fix it! I will look more deeply into this when I get myself onto a different monitor.

The Dreaded Purple Fringe
There seems to be an awful lot of discussion going on in the digital camera world about the dreaded purple fringe. This phenomenon exhibits its self as an out of focus purple ghost image rimming parts of a digital picture.
This event, purple fringing, was thought to have been brought about strictly by Chromatic Aberration in the lens design. CA occurs when one to all three of the primary wavelength colors (RGB) do not focus at the same destination point. Less expensive or less exacting lenses exhibit this behavior regularly. It is easy to see with a single element lens, such as a magnifying glass. Tip the glass so that the light rays are not passing directly through its center and at some point a rainbow effect will be cast upon the reflecting surface. Modern camera lenses utilize multiple lens elements in an attempt to prevent this problem. Lens creators also use special low dispersion glass (LD, UD or ED designations), special lens coatings, aspherically ground elements and occasionally fluorite elements to counter act design problems and to eliminate CA in their more expensive lines. Most of the low end digital cameras ($100-$200) have been accused of having simple and inexpensive lenses which are more likely to be plagued with CA, thus more purple fringing. However, with some of the new 8 megapixel cameras, with great lenses, reporting purple fringing, researchers began looking deeper than just the taking lens.
The imaging sensors became the next suspicion. The light imaging sites on the sensor, often wrongly referred to as sensor pixels, are set down into the silicon chip material like small buckets. The imaging sites must physically be separated from each other to avoid bloom or bleed over. Bloom is blown out highlights, like in a fantasy dream sequence, which leave temporary white trails. Bleed over is color smearing and polluted color intensity between sites. To funnel light down into the separating buckets each site is covered with a microscopic lens. With eight million tiny lenses, all within three eights of an inch, there is bound to be stray or inadvertent reflected light. So test shots were made in an attempt to determine if CA of the site lenses was the culprit. It does not appear that the site lenses alone are the problem.
Tests have been conducted to see if too narrow of site spacing (too tightly packaged) was the problem. Testers wanted to know if voltage was leaking from one image bucket to the next because of narrow spacing. Testing began on the algorithms used by each manufacturer to process their image information to see if they were problematic. Tests were also conducted to see if extra or unfocused UV or Infrared was causing site pollution. None of these symptoms alone seemed to be the problem.
To date there is no clear single item that is responsible for purple fringing. We do know that is most likely to happen when apertures of greater than f/4 are used, when a wide angle of 28mm (or equivalent) or wider is used and when the subject to background contrast is high. Since it is most likely to happen under those conditions, avoid that combination if possible. To remedy some of these problems it seems to be most advisable to use a lens hood or shield the lens from light raking directly a crossed it. Under exposure and low light shooting conditions will also aggravate the situation. Image processing attempts to find or add something where really there is nothing. Even when shooting film, large dark areas are problematic. The digital noise in dark areas will lend itself to the digital purple dread. Avoid image sharpening in Photoshop where there are large areas of dark values. Some of the fringe may be reduced in Photoshop by image> adjust> color balance and adjusting down the blue channel enough to camouflage the purple.

Chris:
Intriguing - I downloaded and saved from UF in case the original image had changed during upload. Then opened it at 150% view. While I do see a brighter flashback here or there . . . I really can't see purple. I will have to check on a different monitor . . . the work monitor is NOT the greatest. The white area and triangles visible is skin . . . not feathers which do not grow there. You can see some flashback from some of the triangular areas of skin. I don't know what CS2 is, I use PS elements 4. I do always shoot in RAW though. I do think the quality might improve with a better lens for this purpose though . . . Thanks for spending so much time on this Chris . . . I do appreciate the feedback. I will be looking on a different monitor but only thanks to your comment. I suspect the tight crop and blow-up may have caused whatever issues you're referring to and will simply eliminate that next time. We'll know better come August when I change lenses!

Hi Doyle, I think that the purple fringin is more visible when viewing closer to a 100% pixel view. I cropped in on what I thought was the most extreme example of the fringing.
PS CS2 has a nice feature where you can adjust the individual color channels to correct for this if shooting RAW.

Chris

These birds aren't smooth anywhere . . . although they seem so from a distance.
Your comment is third . . . the first comment explains that it was, in fact, cropped from a larger photo and the photo it was cropped from is attached.
I don't see the purple tint on the blacks and haven't done any color or hue adjustments . . . Wonder if they're subtle and natural or if I need to check from another monitor.....Hmmmmm . . . Probably should have used the Macro lense to pull in more detail . . . have to look into that in August when I return! Thanks for the comments.

Soory D... should have scrolled down first! I tink the extreme crop is what resulted in the above stated loss of detail and purple fringing.
Maybe just zooming in on the birds eye would have been abetter route?

Nice photo, doesn't really look as smooth as it should.. the detail could be quite abit finer.
Also the blacks seem to have a purple tint to them and don't really appear to be true black.
I'm curious... was this cropped from a larger photo?
