When I open some images from aperture into the external editor (in my case CS2) they appear with crazy vertical streaks. I think it has something to do with certain combinations of Sharpening and Noise reduction. If I adjust them I can get aperture to open a new version in CS2 without the streaks.

Anyone else encountered this?

Are they there in your native camera program?
 
Slow on a Dual 2.7?
Hmmm that can't be good, no wonder it's always on a Quad at the Apple Store.

Oddly, I have not seen any other reports on streaks like these (I've been following these forums and the Apple support forums as well). Perhaps they are unique to your combination of Aperture and video card - what video card do you have?

An intersting test would be to see if you see these same streaks in preview (probably you will but it will confirm it's the RAW conversion and not something else in Aperture).

HI,

as aperture does all it's processing in the GPU, i would say you have a memory issue on your graphics card. as the other apps you have tried do not use the GPU then those glitches will not appear..

Try the same workflow and files on a machine at your local apple store to see if the same thing happens.

Aperture pushes the GPU very hard, if there are memory holes or errors, then an application like Aperture is sure to find them.

do you run any other GPU intensive apps? it may be worth giving them a try.

do you see the errors on-screen, or only when you output the image? just a thought.

cheers

No not so far. If you like send me the Raw and I'll see if my version exports a Tiff with the same problems.

if my version is O.K it would suggest a local hardware/software problem. If not then Apertures conversion engine is at fault.

I'm still getting these streaks when I open a file into photoshop from aperture.

I've isolated it to a combination of Sharpening and Noise reduction. (example: Noise reduction at .30, sharpening at .70) If I turn off either the sharpening or the noise, the streaks won't render. No streaks appear when I have Aperture do it's standard export to file.

Oh, and these are still happening after an upgrade to the X800 XT
card.

This is happening to 1-DmkIIn files, doesn't seam to happen at all
to 20D or 10D images.

I don't have much in the way of help to offer, but did you read the thread about Apple looking for image submissions of problem images? It was a pipeline just for RAW conversion issues, but it seems like perhaps you could submit your image there, along with a TIFF export and a note explaining it's a bug between the sharpen and noise filters. They might have it fixed quicker with an example image, I think that's your best bet.

The web page describing how to upload is at:

Sorry to hear the video card upgrade did not fix this, but in some ways that is good news as it would be unfortunate to have graphical issues that varied depending on the card you had.

Perhaps you could explore adding other adjustments making this problem go away (like just adding a very slight exposure or Shadows & Highlights adjustment).

Not to go off topic, but if you ARE going to CS2 with the image, why not turn off

sharpening and noise reduction and do that in CS2? CS2's sharpening and noise reduction
are far better than Aperture's (in my opinion of course)
