COLOR Adjusting and Embedded information

[ppardue]

I have received files that are *.tif format. I am trying to convert them to JPEG, the original file is waying toward red in the skin tones.

1) when opening the *.tif format in PHOTOSHOP version 7 a window alerts me for choices, because of the original format (I recieved these from a local newspaper--they are photos of my son) anyway: this window comes up: The document "name.tif" has an embedded color profile that does not match the current RGB working space.

Embedded: Nikon Adobe RGB 4.0.0.3000
Working: sRGB IEC61966-2.1

How do you want to proceed
1) Use embedded profile
2) Convert document's color to the working space
3) Discard the embedded profile (don't color manage)

2) I have tried all three without any visual difference.

3) The colors on the tif and jpeg are harshly red (normally)

Question:
Does anyone have any documentation as to how to color adjust a colored photo and about the embedded information. Is there any hope with the *.tif file.

Thank you for your time. :lol:

I'm surprised that there is no difference. It's quite possible, but it's still surprising. Check again, paying close attention to the extreme colors (pure Red, pure cyan, etc.) These extreme colors are the areas which will show the difference, if any.

Option 1 may be useless if you don't have that profile - I don't think it's a profile normally available with PS but I'm not positive. If you have that profile it's your best bet though. Option 3 is almost always a bad idea if the image has an embedded profile. Which leaves option 2, which is your best choice.

However, I would change my working space to Adobe RGB (and check for the Nikon profile while you're there) and then choose option 2. Converting to sRGB will squash the color space a bit, since Adobe RGB is a larger color space.

But if you don't see a difference between all three - especially after changing your working space to Adobe RGB - then there's nothing to be done. You'll have to open the image and fix the colors to your satisfaction.

I'm fairly sure that Nikon Adobe RGB is the same as Adobe RGB. Neither Adobe nor Nikon invented or defined this color space!

Presumably the original image was shot on a N*k*n in Adobe RGB. Presumably, it was never converted to another space (or else it should be labeled with a different profile). Therefore:

It should like good in Adobe RGB (i.e. using the embedded profile). You are thus overriding your working color space.

It should like fine if converted to sRGB - your working color space. Conversion is performed to make an image look very similar from one color space to another.

Your 3rd option (do nothing) should cause the image to look somewhat washed out since you are viewing Adobe RGB coded colors in your working sRGB color space.

If you don't view images side-by-side, you might not notice the difference.

You could waste some time and convert the image to Adobe RGB and compared the individual pixel color numbers to the N*k*n Adobe RGB image. I bet they are the same -- all 6.3 million pixels. :)
