| Change your image mode to sRGB before you save for web. |

| Its a colorspace thing, Its been discussed at length before, try doing a forum search, something like "save for web". I am a relative noob with dealing with color profiles/spaces, so I am not the best person to ask. |

Oooh... no, don't do that! Your captured image already has a profile, and assigning an sRGB profile to a photo shot in another color space would "lock in" the same bad conversion he's getting with Save for Web. You should convert the profile to sRGB and use MonitorRGB under Proof Setup to preview the photo as it would look on a typical monitor (assuming the color on your own monitor is reasonably accurate). |

Thanks to everyone for the input.
Have a follow up Q.
When i open a photo it tells me that the photo has an embedded color profile that doesnt match the working space.
When i convert it to the working space, i can then save for web and its fine. (after having set proof setup to monitorRGB)
This all started when i added these color profile to my camera for different shooting situations.
Im wondering if by converting it to working space, am I losing the settings of those color profiles?

For Mac users.
I use Firefox browser on my Imac and noticed that my photos (converted to sRGB) looked washed out and a bit desaturated compared to the original on my desktop after I uploaded them to DP challenge.
However when I used my Safari browser from the same Imac the uploaded photo's looked exactly the same as the original on my desktop.
So obviously the issue was with the Firefox browser.
After googling for this issue I found the problem and the solution:
Test your browser:
//news.cnet.com/Safari-ushers-in-better-browser-colors/2100-1012_3-6191815.html?tag=mncol;txt
Here it is. Test your browser rendition here.
Is your browser ICC Version 4 ready?
//www.color.org/version4html.xalter
How to fix the issue with your Firefox browser:
There are two ways to turn on color profile support in Firefox 3. The easiest is to install the Color Management add-on (which will work with Firefox 3 Beta 5). After you install the add-on and restart Firefox 3, color profile support is enabled, and you can specify a custom color profile by going to the Tools menu, selecting “Add-ons”, and clicking the Color Management add-on “Preferences” button. If you do not specify a color profile, the system default profile will be used, which should be OK for most people.

Now my images look the same as the original on my desktop when viewing them on DPC with either the Firefox or Safari browser
Ps. Another browser check and info:
Here is another ICC browser test and info:

Except that not everyone uses a colour managed browser. For those that don't, their browser assumes the image to be in the sRGB colourspace.
Converting to sRGB before uploading makes sure that the image will be treated the same regardless of the colour management settings in the browser. |

This Ballard guy explains things in detail: //www.gballard.net/psd/saveforwebshift.html
My Firefox browser was not color management enabled either and yet rendered sRGB converted images differently when viewing them on DPchallenge to the same image on my desktop. Since I enabled color management on my Firefox browser the images are now rendered the same.
Here is a whole Flickr forum discussion on this issue: //www.flickr.com/groups/adobe_lightroom/discuss/72157614970517024/
I just came across this bit of info that shows it might have something to do with RAW conversion. This makes sense as I did not experience this issue with Jpegs from the camera, only with RAW files converted into TIFF and them to Jpeg. I edit and convert my RAW files with iPhoto editor and then convert to 16 bit Tiff for further editing in an external editor. This could couse the color profile to be altered somehow as described in this article although my Jpegs which I get from my TIFF files I convert to sRGB as well.
"Professional cameras tend to have two modes of file export: the first is to export JPEG or TIFF files with an embedded profile, while the second is to export camera raw date for converting at a later stage.
If the embedded profile option is chosen, the on-board firmware renders the image to a well-defined standard colour space such as sRGB or Adobe RGB (1998). The corresponding profile is embedded into the image.
If the camera raw option is chosen, the conversion software will handle the rendering and will normally suggest a suitable profile to be embedded into the image file.:

Came across a wealth of information on this website. Worth checking out as there is just so much info on this subject that it will take months to really absorb it all. Well it would for me anyway as I am new to most of this tech jargon. //www.digitaldog.net/tips/index.shtml

Let me expand. If you are viewing an image that is not in the sRGB space, the browser will assign the sRGB space (not convert to) and it will therefore look different than in a browser that is colour managed. Hence, converting to sRGB prior to uploading will ensure consistent viewing (monitor calibration issues aside) of images regardless of whether the browser is colour managed or not. |

Thanks for your feedback Colette. I appreciate it. Funny thing is..I have disabled the color management function on my Firefox browser again and it now does not show any difference anymore between an image on my desktop or one on the web. Weird because before with color management disabled it would show a difference.
Ps. I always work in sRGB with my images from start to finish. I never use anything else. |
