Hi,

i´ve got some trouble using the adjustment Layer "Hue/Saturation" in Photoshop CS3 running Windows XP.
Colored pixels appear in random positions. When I hide and show the exact same layer again, the pixels appear on a different position. But are still there. And these are saved to the File if I write a tiff or jpg.

Here´s a Link to see the result of my Image.

If you had the same problem before I would be pleased if you let me know.

Best regards,

Martin

System: Win XP
Graphics: Nvidia 7600 GT 256 MB Ram

from a while back from one of the adobe engineers:

Chris Cox – 01:17pm Feb 7, 2003 Pacific (#7 of 15)

If you zoom in and they go away, it’s probably the video card.

If you zoom in and out and they change, it’s probably bad RAM.

If the image looks fine, you save it, then reload it and it’s corrupted – then it’s probably the hard disk.

Hi Dave, thanks for the Answer.

But I guess there might be a possibility number 4:

I zoom in and out and those Pixels stay and don´t change at all.

And the image doesn´t look fine when I save it nor when I relaod it in the same application on the same computer.

But I changed to another computer with Photoshop 6 installed and all the pixel bugs disappear.

what happens when you open the same file on another computer. i.e. save it on the problem computer then open it on the "good" system. is the damage saved with the image on the problem computer?

There are no pixel bugs at all when I open the saved file on the second system.

hmm… and are the pixels always in the same places when you open on the bad system, or do they change location?

In case of opening the file those pixels change their location. It´s the same effect like hiding/showing the adjustment-layer.

but once you start zooming in and out they stay in the same place? scrolling around the document they stay?

i’m inclined to think video card (if you have a spare one to swap in and out you could check). i was leaning towards hard drive but as you say they aren’t saved with the file (opens clean on good system) that would seem to rule that out, or at least minimize it. wouldn’t be a bad idea to reseat the HD cables in any event.

either way i believe you’re looking at a hardware problem on that system.

Thanks for your answer.

There´s still no solution but I installed a previous Version of Photoshop (6) on that "bad" system and the result is that there are no buggy pixels.

Might there be a hardware-software conflict between Photoshop CS3 and my nvidia card?

I don´t own a second pcie graphics card so i cannot test to change the card.

try going into control panel> display> settings> advanced> troubleshooting and turning down hardware acceleration. if that fixes it it WOULD indicate a driver problem rather than hardware.

Thank you for your answer again.

But that didn´t fix it either.

I think my first step would be to do a clean reinstall of the CS3 software package.

I don’t htink it’s software but if it is, turning down the hardware acceleration and checking the driver takes about 5 minutes. reinstalling cs3? 20 mins to and hour.

oh are you saying you did try turning down the acceration and the problem persisted? i’m afraid i’m about 90% sure you’ve got a hardware problems somewhere.

good luck.

Before you give up – check if you’ve checked the view out of gamut warning menu item (can’t remember the exact name, haven’t got PS on this machine) – that’s what it looks like to me.

(although just read that they stay the same on zooming in – does that mean they stay the same absolute size, or relative to the image?)

@dave:
Indeed I tried different graphic drivers and turned off the hardware acceleration. I also turned off write combining. No changes.

@graeme:
When I am zooming in an out the "broken" pixels stay the same size related to the image. They are behaving like usual pixels. As if they were burned in the image. Only when I hide/show the adjustment layer those pixels change in position and color. And of course when I change the Hue/Saturation sliders.

I´ve uploaded the .psd file if you would like to test:

(You need to zoom in about 400% to see the green dots)

F.Y.I. The reinstall of Photoshop did not change a bit. Similar artifacts as before appear.

Another interesting discovery:
I tested all the other adjustement layers and there appear no buggy pixels.

When I press "colorize" button in the Hue/Saturation adjustment layer, no buggy "jumping" pixels occur either while dragging the Sliders.

It is really especially in the default Hue/Saturation function when I am playing around with the sliders.
And by the way, it´s not only the Hue/Saturation adjustment layer. Even the normal Hue/Saturation function from the Image->Adjustments menu causes these "effects".

Anyway a workaround could be to avoid the Hue/Saturation adjustment layer and simulate the effect with other controls like "Color Balance" or "Selective Color".

The solution was to reduce the clock speed of the processor from 3.6 to 3.41 GHz. My processor is an overclocked Pentium D, native speed at 2.6 GHz.

That´s the whole story.

Thank you guys for the answeres and sorry for the confusion.

kinda sorta. woulda been good info to have. ordinarily when debugging one of the 1st steps is to make sure you remove any ‘tweaks’ you have set up and get as close to a vanilla config as you can.
