I am pretty confused now with how to save jpegs for smumug or when giving photos to friends. I thought that when "saving as" then select jpg. Clicking on the ICC profile and selecting sRGB will use sRGB to display. When I select save for the web. it doesn't save EXIF and the sRGB says unknown when I click in smugmug's info menu.

I usually work on PSD 16bit and when I am ready to make JPG I do these:

1.0 image->mode 8 bit
2.0 Save as
3.0 Select JPEG form the pull down menu
4.0 Clink on ICC ( sRGB)
5.0 Select IQ 11, standard.

Will this display iamges correctly on the web after D/L to smumug?

With SmugMug, it doesn't matter. If your image is in Adobe RGB, ProPhoto RGB, or CYMK; SmugMug will convert the file to sRGB when you upload it.

I'm at work so I can't check deeper into this, but I'd check the metadata on both images locally and, if they both show sRGB, I'd post a question on www.dgrin.com (http://www.dgrin.com) (SmugMug's forum) as to why they're showing up different.

Here's the info from SmugMug:

Does colorspace matter? (javascript:void(0);)
Gotcha: The only JPEG colorspace (http://www.smugmug.com/help/srgb-versus-adobe-rgb-1998) supported reliably by Internet browser software like Microsoft Internet Explorer is sRGB.
If your photo is in the Adobe RGB (1998) (http://www.smugmug.com/help/srgb-versus-adobe-rgb-1998), CMYK, or Prophoto color space, we convert it to sRGB. Your viewers will thank you.

It's probably because when you save for web, all the metadata is stripped out of te JPEG and that Metadata is what SmugMug uses to determine the profile. Flatten and do "Save As" versus Save for Web in order to keep your metadata intact.

Yes, I may have misinterpreted the OP's post in that I thought he was following the series of steps he outlined for both images. If they were processed one using Save to Web and one using Save As, it would account for the difference in the metadata. There must be another way for SmugMug to know whether to convert to sRGB at that point or perhaps it assumes sRGB if the metadata isn't present. Not quite sure what else is present in a JPG.
