photoshop file display observation/question

In a particular picture in Photoshop document format taken with a digital rebel xt and displayed on PS CS2, there is a narrow rusted cable in the distance against the blue sky. The blue of the sky appears to bleed into the dark color of the backlit cable. When I grab the picture to move it around, the blue bleed disappears and the cable takes on the correct dark rusty color. When I stop moving the picture around, the blue bleed from the sky appears again.
This makes me think the camera actually recorded the correct color information for the cable, but Photoshop is mishandling the information when it displays the picture in normal mode, but displays the information correctly when it is displayed for the photo movement function. Can anyone explain what is going on?

when you zoom in it looks correct??
if so it is a monitor display problem
try higher resolution setting or better refresh rate??

Hi. I'm not changing the zoom when I see the change, just grabbing the picture with the 'hand' tool to move the view around.

Mike,

During the Drag action, the image is actually shown at a lower resolution, so you are not likely to see the problem at that time. When you have positioned it, PS goes to the set rez for the monitor.

The same thing happens, when you're using one of the Transform Tools, while, say Scaling, the image goes to a lower rez, until you release the handle(s). I've had it stick at the lower rez, until I double-click or Enter, but that is not often, and was probably on some of my slower/smaller VRAM vid cards. Do not recall seeing that happen for some time now.

Had the image been shot RAW, you could possibly clean it up easily with the Color Fringing Tools in ARC. If you shot JPG, then a bit more manual work might be required. The color fringing is a result of one, or more, of several factors, the lens, the sensor in the camera, JPG compression, sharpening in camera, and the lighting.

Jumping in, hope not to offend, but I smell new toys for x-mas :-)

I am using RAW now, with much enjoyment and mirth (when looking back at my previous stuff)

However, I am at a loss to understand what the ARC bit is, have I missed a play toy somewhere on the RAW plug in, or is it shorthand for something I am playing with now???

Thanks for the feedback. Yes, I did shoot in raw, so I could try some fringe cleanup in the raw imaging tool. The coloring doesn't look like the bi-color fringes I sometimes see. The color in the dark area is only blue.

I did think PS was simplifying its display when moving, although it's hard to see any degradation of the image after stopping the movement but still holding the button down. About the only change I notice is the loss of blue sky bleeding into the dark rust color. As you stop moving the picture and new areas of rusted cable are revealed, the detail and color in the newly visible rusted area is outstanding. The color of the cable in the area that had been in the original view and is still visible after the move still shows the blue bleed. When you release the button the blue bleed returns to the entire cable in the view. It seems that Adobe made a great clean-up tool algorithm without perhaps realizing it.

Keith,

The ARC refers to Adobe Raw Converter, so if you have the RAW plug-in that matches your camera(s), there is nothing new to add - sorry. Maybe another 1GB stick of RAM, or a 750GB ATA HDD would suffice beneath the tree <G>.

I bet you have "Pixel Doubling" turned on in the Preferences. If Pixel Doubling is on, then what you see on your screen when you pan around an image is a crude, low-resolution proxy. When you stop panning, you switch back to high-resolution mode.
