What ISO? What noise reduction setting? What zoom in CR?
As far as ISO, it doesn't seem to matter. I saw it in images at 100, and also at 400. Naturally I was viewing at 100% in Camera RAW. I have the Color Noise Reduction setting at a default of about 30, but I also played around with that it it didn't seem to make a difference. I also played around with Luminance - again to no avail. I forgot to mention in the original post that I tried using sharpening with various settings, and it just got worse. As I mentioned, this problem also occurs with Amount set to 0.
I would also like to point out that I use Canon 'L' Series Lenses, the best glass they provide for the EOS line of cameras.
Could you post a screenshot? are you viewing images at 100% magnification?
I don't know how to, or if I can, submit a screenshot. However what I have done is put a sample file on my web server here:
I recommend downloading the file and view at 200% to really see the effect, although it is visible at 100%, and becomes more pronounced if you attempt to sharpen the image. For this example, I did a small amount of sharpening, and I have also included a comparison of the exact same image having used RAW 4.0. The settings I used to sharpen each one were:
Camera RAW 4.0
Camera RAW 4.1
Adjusting the Color Noise filter slider back and forth seems to have the greatest effect on this phenomenon, however it's always there regardless of the setting.
Mike, Are you using a mac or a PC? on a PC, hit the Print Screen button, create a new document and Paste the image.
The print screen shortcut on a mac is Shift-Apple-3 you'll hear a shutter sound, and a file is placed on your desktop.
Create a new document where? Paste it where? I can't paste an image inside this text box. And I don't need to create a new document within Photoshop. I've already been through all that. I'm not sure what you're getting at.
You do the print screen operation, then create a new document in Photoshop, paste the image (on a pc) on a mac; you open the PNG file, then crop it to show the issue, and reduce slightly the image size, and post the image on a free image hosting site (flickr, etc.) and insert a link in you post here.
I did all that. If you read the post I left after your post about leaving a screen shot, I did exactly that. I created a sample image and left it on my web site. Here's the address again:
Read the post I left previsouly for the sharpening settings I used for each one.
Mike, you're not alone with this problem. I noticed the same rippling effect on my photos taken with Canon EOS 400D. At first I thought it must be 4.0 and 4.1 producing different renderings of the image with the same sharpening settings, but as your findings suggest, it may not be that simple.
Thanks, Jack, for sounding off on this topic. Jeff Schewe was the first to respond to this thread (as you may already know, he was totally involved in the creation of the new version of Camera RAW), so hopefully he's working on it.
> "I am getting a weird rippling effect in the areas where my images go out of focus".
I downloaded the TIFF image http://www.eclecticimagery.com/composite.tif
and superimposed the ACR 4.0 and ACR 4.1 versions as separate layers on top of one-another, pixel-aligned. I then spent some time clicking the visibility of the top layer.
Even at 200% and 400%, all I can see it that ACR 4.1 appears to be very slightly sharper, and has slightly less noise.
I can't detect the "weird rippling effect" that the original poster mentioned. I think there was a very slight amount of small-scale posterisation in the ACR 4.1 image, perhaps resulting from a reduction in the amount of "dither" that was present in ACR 4.1 because of the reduced amount of noise.
I converted the ACR 4.1 layer ready for Smart Filters, and applied Noise at 1 (I would have prefered less) and Gaussian Blur at 0.3, to try to get a match between them (Noise below Gaussian Blur). When I toggle between them, the effect is far less, although not exactly the same.
But this does suggest that one way of making ACR 4.1 look like ACR 4.0 is to add a combination of noise & blur!
