I note you compare Safari and IE. What's your opinion of color management if using Windows Firefox? Firefox doesn't have colour management, Opera doesn't have colour management, IE doesn't have colour management.. Safari is the only browser to support it. Ray |

That's not technically true; there are several other Mac browsers that have it, by virtue of using the Apple frameworks. Most of the software you'd use to view pictures on a Mac will be color-managed, with the notable exception of Firefox. Internet Explorer for the Mac even had it, when it existed.

You can't target them, since they don't have color management. All you can do is give them sRGB and hope for the best. Since most people also don't have their monitors calibrated or set anywhere near correctly, this isn't as big a deal as it seems; you're really just hoping for the best anyway. And for any one viewer, all the pictures he sees will be *consistently* off, so he'll be used to the error. The key thing is to make sure to convert to sRGB. If you don't do that, things get ugly. This is unfortunate, since most monitors and almost all output processes can exceed sRGB, and the conversion visibly harms some images, but that's what we have to work with at this point and for the near future. -- Jeremy | | http://www.flickr.com/photos/100mph/ |

That's great, but I was answering louise's question on Firefox and colour management in Windows, not addressing the original poster of this thread. Ray |

I'm not a mac user, so I'm only going from what I've heard from mac users, which has always been "only safari". Ray |

If the OP is concerned about his actual audience, he should be tuning his images to look their best on non colour managed browsers. And how would that differ from tuning them for Safari? In other words, I tune my image using CS3 on my screen, calibrated with Spyder2 and then I upload them to zenfolio. When I look at them, I'm looking at them in FF or IE. Louise |

I've just started loading on the web and I am loading RGB, not sRGB. I haven't seen anything I think is "ugly" although occasionally things look a little darker. What do you mean by ugly?

Well, if you're working in Adobe RGB or ProPhoto RGB or something like that, and you put the images on the web like that, they will be desaturated and dull in the browser (unless the browser is Safari or one of the minor Mac ones that does color management). They might also be darker or lighter depending on which color profile you use. -- Jeremy | | http://www.flickr.com/photos/100mph/ |

They might also be darker or lighter depending on which color profile you use. OK - let's hope I can keep this straight because I often get confused about color space etc. I'm using a Nikon D40X and I have it set to take photos with Adobe RGB I have calibrated by Sony CRT with a Spyder2 I am using an HP 8250 (6 inks) and Photoshop CS3 I have PS set for the working space which is the calibrated Spyder profile PS color management says "convert to working RGB" When I print, I select the HP printer and particular paper for that profile, and color management is managed by application PS). Therefore, I'm under an impression that I am working in RGB straight through the printing process. BUT - when I put my photos on line (www.madeline.zenfolio.com), I simply take the files I've created (usually TIFFS) and I save as jpg highest quality. This makes this an acceptable size for uploading to zenfolio. Are you saying that at the point I am saving a tif as a jpg for the purpose of uploading, I should then take the jpg I've created and convert it to sRGB before uploading it? Hope this was clear and thanks in advance for your help. Louise |

As a working space you should use one of the standard device-independent spaces such as sRGB, Adobe RGB, and so on. -- John Bean |
