Color Space for Hosting
Hi Everyone. I was wondering if I need to convert my images to sRGB for use with Smugmug\Zenfolio? I shoot everything RGB and am going to try out both of those services before making a decision..

Thanks..

Yes and also No.The host should not care what the colourspace is..

But the user OS and more importantly the user Browser cares about the colourspace. The accepted usage at present is sRGB as there are very few browsers which are colourspace-aware..

Yes. You should ensure your images are converted to sRGB before uploading to the web, but only if they are in something OTHER than sRGB, of course..

SRGB is standard on the web, and is assumed by most browsers..

However, saying that you "shoot everything RGB" isn't telling us enough to say whether conversion is necessary or not, because ......

'RGB' is just a "mode" of digital colour description, not a colour space, as such. Other modes of colour description are CMYK, CIE L*a*b, Greyscale etc..

Most digital cameras default to sRGB space, but many can be set to Adobe RGB (1998) space as an alternative ...... [unless you shoot RAW, in which case colour space is set by user at the point of "colour mapping" in the RAW processing software.].

I hope this helps.Regards,Baz..

I should have said AdobeRGB. If I convert them to sRGB wouldn't that affect print quality...

Conversions made in Photoshop using the Adobe Colour Engine do not sacrifice a great deal of quality.... [obviously, you shouldn't go back and forth multiple times.].

However, if you are printing from the webservice, I cannot say..

Perhaps they can make use of the Adobe space for your prints, if you have used it to shoot with. But then, I think perhaps you should be asking them, THIS question...[???].

I think and am pretty sure that the online photo hosting sites do an automatic conversion of uploaded images to sRGB. So it is not necessary to do a preconversion before uploading.Willhttp://www.pbase.com/willcarson/inbox..

I wouldn't count on that... a while back I uploaded some "Nikon sRGB" colorspace pictures to webshots, and they looked horrible - I had to convert them to sRGB IEC6... and all was well..

I don't use Adobe RGB, but I've read that most people who use this do so only if they print at home, or their print service supports this. But for public use, I would convert everything to sRGB IEC6... to know that you won't have compatibility issues..
