Hi – I’m experiencing "colour shifting" when I’m viewing RAW files (Photoshop CS1 – WinXP).

It seems like some camera raw settings are being applied as a preview is generated, and these settings are being preserved as I try to open the file. This is a recent problem – it hasn’t always happened.

When I view the same files in the canon file viewer utility, they appear to be correct. I have downloaded the latest version of the camera raw plugin.

Any info would be appreciated – thanks.

The default ‘camera’ settings are applied like that and are more contrasty that the first thumbnails you see but that shouldn’t effect hue, just saturation, brightnerss, etc. You can change the default settings to whatever you like from the drop menu next to the drop box at the top. Actual camera settings can only be detected by the camera manufacturer’s software. The initial thumbnail view in ACR is a low-contrast ‘raw’ looking version.

and these settings are being preserved as I try to open
the file. This is a recent problem – it hasn’t always happened.

Hi.

You have probably managed to change the default preview settings by accident.

It does not really matter a damn what the Preview of the RAW files look like in the RAW Converter, BEFORE you make the conversion.

The only thing that matters is what they look like after you set all the Sliders, and make the conversion to Tiff.

I printed a file straight out of the camera onto a Fuji Frontier photographic printer, it looked well saturated and tonally correct. I then opened the same file in Photoshop and immediately saved it, took it to the lab and printed it on the same machine, it looked unsaturated, colour cast (green/cyan) and was generally ruined. Colour management was turned off and I made no adjustments to the file. Any explanations welcome.

Did you open the raw version in PS? Converted to AdobeRGB perhaps?

I’m talking about JPG files, no adjustments were made at all

Color management was turned off, you say. That means the image will be opened in your default color space. Is that AdobeRGB by any chance?

The ‘No color management’ setting in Photoshop is very misleading. It only means that your images will not be tagged. However, they will be opened in your default color space, and when viewed on screen they will be color managed. But when printed…

Did you print at the same lab ?
Any chance of an auto color correction by the lab ?

When you saved it, did PS added an embedded color space ?

Same lab, same day. The embedded file was sRGB which is the same as the camera.

That contradicts to what to said earlier. You said ‘Color management was turned off’, which means there shouldn’t be any embedded profile at all.

The file is embedded by the camera

That doesn’t mean anything if you work in RAW. The RAW converter determines the color space, not the camera. Check that your RAW convertyer uses sRGB, because this could be the reason of your problem.

I am talking about a JPG file not a RAW file, it was opened in Photoshop and colour management was turned off (in Photoshop), then it was saved and printed. At the same time I printed the same picture straight from the camera.

OK, you confused me because the title of this message reads ‘Camera RAW and colour shift’.

In that case, try it again with color management *NOT* turned off in Photoshop.
