How do I save my digital images (from a canon G3 camera) so the embedded rgb colour profile is discarded permantely?

When I import into PS7 I choose the discard embedded profile option, but even after manipulating the image and saving that original profile is still there, and causes problems when importing into other programs.

Help will be appreciated.
Thank you.

In the "save for web" dialog you can prevent the embedding of a profile.

Is it actually an imbedded profile? , or could you remove it using the IgnoreExif utility ?

I don’t have the save for web option,, it’s not active for some reason.

I tried doing it in Image ready also w/ no luck

Yes I believe it is an embedded profile,, because when I choose the "ignore embedded profile" option when first opening the file in PS7 it corrects the colour.

But the saved versions even after doing that are still yellow when trying to get them to Photoshop Album.

I don’t have the IgnoreExif Utility..

I’ll look for that.

thanks

I got the "ignore EXIF utility" and it hasn’t helped.

Is your image in 16 bit mode? That’s unusual.

Yes, it is,,

I know, this is really frustrating!

If you change your image to 8bit, then you can strip the profile with Save For Web – that’s why it’s not available.

You should be able to Image|Mode|Assign to color profile|Don’t color manage this document. When you save the image, there should be no profile in the image.

I’m completely at a loss.

Wait a minute. You’re saying that it’s a 16-bit image. It’s in photoshop and you cannot do Image|Mode|8-bit? What is checked in the list of image modes when you do Image|Mode?

Perhaps you should try resetting your preferences, as there is something weird happening. I tried your process with an image from my camera (8bit), and had no problems.

Confirming the steps I took, that worked.

1) open camera file in Photoshop
2) get message regarding profile (embedded was sRGB)
3) tell to discard profile
4) Save for web – use different file name (just to keep clear on which is which)
5) Close original image (it will ask if you want to save changes, even if you did the save for web)
6) open saved-for-web file
7) get message regarding profile (none embedded)

EDIT: was typing this up while Tony posted his query on what is/isn’t available in the Image|Mode menu – there is definitely something weird going on here …

WHat I’m saying is that in either 8bit or 16 bit I don’t have the option to ‘save to web"….where I can permanently discard the embedded colour profile.

That is where the problem evidently lies.

If I could do that there shouldn’t be any problem should there?

That option is "greyed" out… and non functional. it shows on the list but isn’t usuable.

And why do they save like that even if they’ve been altered?

First, you only want to save for web if you’re saving a JPG or a Gif. But in reality, you SHOULD be able to strip the profile off by not color managing the document (Image|Mode|Assign to profile).

Look at the Image Title Bar – is the document RGB? Are there any characters after it like an asterisk (*) or a hash sign(#)?
JH

Sep 22, 2003
Yes, I’m trying to save JPG’s.
Yes, RGB no * or # in the title bar.

OK here’s what is really weird.

I do all this.. everything appears fine,, except of course for not having the option to save for web,, which at this point I’m not going to worry about.

When I go to use an image I’ve done all this to in Photoshop,, I go to create a catalogue in Adobe Photo Album and the thumbnail image in the file list is correct,, right colours etc.

BUT the thumbnail and subsequent imported image have the original embedded colours.. ie way yellow…

This is what is so perplexing why this is happening and why with another adobe product.

I could see if this was another vendor… but it’s adobe!

Well, you may not want to worry about it, but I think it indicates a major problem – I’ve *never* had this option greyed out, that I can recall, regardless of colour profiles, bit depth etc.

BUT the thumbnail and subsequent imported image have the original embedded colours.. ie way yellow…

If I understand you correctly, when the image has an embedded profile, the colours are off, and when you discard the profile within Photoshop, the colours are correct?

You give way too little information and don’t answer the questions. If you want help, you have to provide more details.

What are your CM presets (Edit|Color Settings)? What is your mode (Image|Mode)? Which profile is embedded? Is it a RAW or JPEG? Or did you convert it with an external RAW converter? Which? To which format? Do you make some changes or correction with the images?

I don’t mean to give too little…. I thought I had given most of this.

I’ll start from the beginning.

1. photoshop7
2. imported images from a canon G3 in jpg the embedded profile is from this source.
3. CM settings,,, custom
RGB: VA720-1. CMYK: US Web coated SWOP v2, gray gamma 22, dot gain 20% RGB/CMYK/Gray all off,,, conversions, Engine, Adobe (ACE), relative colorimetric.
4.I have made multiple changes/manipulations with the images.
5.I discard the embedded profile on import.
6.I use 8 and 16 bit modes, rgb and cmyk and grey scale…..
7.Repeated calibrations adjustments with Adobe Gamma
8. The problems;
a. no save for web function
b. images appear to revert to the original profile when being imported into Photoshop Album. They import fine into Illustrator.

I hope this helps.. I am really at a loss here.. I’ve also got this thread going in the Album forum, but no one there has a clue either.

Thank you for all your help.

Generally you can prevent embedding a profile in any "save" dialog. So, if you open your image, make same corrections or changes, and then go to "save as", you can just uncheck the profile option.

I"ve been doing that,, doesn’t help. This is so weird.

I tried saving w/ the profile I use didn’t help either.

So you could save it without a profile (the profile box unchecked)? But the other application still crashes? Did you reopen it in PS? Was a profile embedded or not? I recommend you to turn on the CM in color settings and choose your way, when you open an image. Referring to the manual, PS does not automatically discard a profile, when the CM is off.

Yes, I can save it without a profile.

The other application doesn’t crash,, just show’s what I perceive as the original profile.

I’ve tried saving it w/ my profile, that doesn’t help either w/ the other program.. still show’s the incorrect/original colours.

YES!!!!!!!!!!!

100th times the charm.

I’ve reinstalled PS,,, confirmed all my settings.

Now when I save w/ my profile it is working.. why? I’m not sure, but at least it’s working.

Now if I could only save for web… but that’s the least of my worries. THank you all so much for your patient reply’s help.

That’s what I thought too.

But it does appear it is still there,, some how.
Of course this all could be some strange thing inhabiting only my machine. Which, with my luck is what it is.

Thanks again.

Without doubting your observation, how do you know it’s still there?

<<Without doubting your observation, how do you know it’s still there? >>

Why I’m assuming it is there;
When I go to open the file(s) in Photoshop album, the "incorrect" colour shows in the preview thumbnail.

Now that I am saving the colour profile in photoshop before I import the image into Album, it initially has the incorrect colour and then corrects itself to my settings.

It is really odd, and I may not be explaining this precisely.. but I do see that original embedded profile colour.

IMO, that is NOT an accurate way to discern whether a profile is present or not. I don’t know anything about photoshop Album, but here’s how *I* would tell if there’s a profile embedded.

After you have Image|Mode|Assign Profile, and indicated not to color manage the document, save the image. Now, open it in Photoshop.

In the bottom of the Photoshop window, there’s a Status Bar. It usually displays Document Sizes. Click on the little arrow next to that and choose Document Profile. What does it say?

Like I said, I may not be describing this accurately… so my apologies if that is so. I’m only going on what I see.

Per your question.

The files that are not opening w/ the correct colour are indicated as being untagged RBG,, this is when, on import into PS, I discard the colour profile.

The image that is importing into album correctly now, is showing my assigned profile VA720-1.

That means they have no profile. Mission accomplished.

You would do well to spend about 15 minutes at Ian Lyons’ most excellent guide to color management. It has helped me, and countless others to gain a grasp of what’s happening.

For what it’s worth, I see in your Colour Management settings, you are using a Viewsonic monitor profile (VA720-1) for your working space. Although this will work fine for you, it’s generally a better idea to use a non-hardware-specific working space such as sRGB or AdobeRGB as a working space – particularly if the images are going to be viewed on other monitors.

cheers

Hmm,,
Just tried both your suggestions, and all the images I had been working on all have the dreaded yellow cast to them, even if I convert to the sRGB profile on opening.

The profile the images out of the camera have is sRGB IEC61966-2.1

I’m getting very confused. The images I have been processing using the monitor profile are showing well on other computers as far as I know.

Thank you for the suggestion
