Can you strip an image of its color profile???

->> I shot some photos recently and didn't set my white balance correctly. When I view the previews of the images in Photo Mechanic with the color matching option off (by toggling the letter "C" on the keyboard" the color doesn't look great but it's not as bad as when the images are opened in Photoshop for editing and the assigned profile is used.
I have tried "Don't color manage" option in Photoshop, but it still looks just as crappy...
If photo mechanic will show me the images without color profiles being taken into account, I imagine there should be a way to force Photoshop to ignore them as well.
*Please do not suggest, the "Don't color manage" option as I have tried it and it does not give the same results when compared to the preview shown in Photo Mechanic.
Any other ideas would be greatly appreciated.

->> what file types???
If you use The Canon software, you can play with the color temps on raw files, before converting them. (this obviously mean that you need to be going from CRW/ CR2 files) I don't know about jpegs, but you may wanna see for yourself.

| ->> What about the Image; Mode: Grayscale option in the Photoshop menu? That seems like a simple solution. |

->> OK. Did some research. please disregard my stupid answer from before. Try using the chanel mixer.
1. Open the picture
2. Go to the Chanel Mixer in the Adjustment Layers pop-up menu or get to it from the Image menu. Check the monochrome box.
3. Use the slider to adjust the image. Make sure the percentages don't add up to more than 100%.
4. Click OK. |

->> Oscar thanks for clarifying, but unfortunately I'm not trying to strip the image of all of its color, rather, just that which is accentuated, so to speak, by the color matrix/profiles that are embedded in the image from my camera.
Thanks for giving it a shot though.

| ->> Oopsie. My bad. Have you tried the Fade option after using Auto Color or the "hidden" options in the Levels dialog box? |

->> Oscar as a matter of fact I did. The auto correct works well on most of the images but there are a few that it just mucks up even more. The fade only takes it back to its original state before the auto correct.
One thing that I just attempted was finding an image that did tone well, and doing a "Color Match" of it. (Which can be found under Image and then Adjustments. That seemed to help quite a bit, although not exactly what I was looking for.
Thanks again though.

->> Justin, this is the extreme down-side of shooting jpgs, but all is not lost.
Open an image that has a known white area.
Add a levels layer to the image. It will automatically open for adjusting.
Click the white-level eyedropper in the bottom right of the dialog.
Click the white area in the photo with the eyedropper. Photoshop will use that as white, adjusting the levels automatically to make it be white.
Click the black-level eyedropper in the bottom right of the dialog. Select something that should have been black. Photoshop will adjust the levels to be black.
Now, if you look at the individual levels for each of the R, G, and B components you'll see how Photoshop did its compensation. You can tweak each color individually until it's how you want it to be.
Click the OK button when you are finished adjusting things, and Photoshop will close the Levels dialog.
Open another image you want to adjust. Drag the Levels layer from your first image into the second one. Photoshop will add that layer and automatically display the color-compensated image. If the compensation is what you want, then flatten the image, and save it back out to a different folder then close it. Repeat as needed.
There are other ways of going about this sort of task, but the Levels dialog and the eyedropper trick will get you back on track the fastest in my experience.
And, yes, I've been there and done that, both to myself and accidently to my wife. It's bad enough when my images showed up all blue because I was on incandescent and shooting in sunlight, but to have to explain to my wife that I didn't have my glasses on when I adjusted the white balance on her camera... not a good feeling. |

->> Justin,
I don't really know the answer to your question, but I don't think you can really do what you are suggesting. You can strip an image of its color profile, but that image always has to be veiwed under some color space.
If you choose the (don't color manage) option in photoshop you are discarding the embedded profile, but you are not changing the working space of photoshop which should be set to Adobe RGB under color settings, so I think the image in photoshop will just be veiwed in the Adobe RGB color space or whatever you have set as your working space.
For color correcting I havn't tried Greg's method but what works pretty well for me is to open either levels or curves and double click on the white eyedropper.
Select an area of the photograph that should be a neutral color. It should have some detail but not be too dark. I find that something between 10-40%K works best.
Click on that area and without moving you mouse change all the R-G-B colors to the highest one by using the tab key. Hit enter and then click the mouse. If you have several images that all have the same color cast you could set up an action to run for each one.

->> Justin:
Instead of auto color, follow the instructions at this link
http://www.creativepro.com/story/feature/17164-1.html
Even though it talks about PS7, the same instructions apply to PS CS. I tried it on your photo and it seemed to get it pretty close to what you want with a single click.
Another option is to use a program like Bibble (www.bibblelabs.com), which I believe will allow you to adjust the color settings even if you shot in jpeg (as opposed to using a RAW/NEF converter). |

->> Justin, one thing I noted in the last photo in the gallery, is that Photo Mechanic doesn't recognize that there is a white-balance applied to the image. That field is blank.
Perhaps there is a setting that PM doesn't understand? Is your version current?
I'm sure Kirk or Dennis at Camera Bits will be interested in what you're experiencing.
Because Photoshop is displaying color that looks good, and it's in PM that the color appears off, I'm thinking the problem lies there. |

->> Hi Justin,
I got an email from Kirk at Camera Bits. Hopefully he contacted you directly, but if he didn't, he noticed the final image had been opened and saved by Photoshop. That would have stripped all the image information that I noticed. Kirk knew that because PhotoMechanic was displaying that Photoshop was the firmware.
He offered to take a look at the original images to see if he could tell what's up. Let me know off-line if you don't have his email and want him to check on the files. |

| ->> Stripping and/or ignoring the color profile won't really solve anything. Since you shot JPEG, you're best be is just setting a custom white balance in Photoshop. |
