one dark photo is brightened by SmugMug

Pindy

I have read in the past all the great info on color spaces and sRGB and 2.2 Gamma and all that and have made the changes necessary. I live in a veritable color paradise now—thanks.

However, this morning I uploaded a particularly (intentionally) dark photo and I believe the built-in color correction algo has brightened it and I'm not pleased! The photo doesn't show the same issue on my Flickr site so that's what I'm chalking it up to. All exporting from Aperture makes sure the files are sRGB.

Is there any way to work around this, if it is indeed the problem?

Notice the high grain visible and too much detail in the tail number:

Uh oh—something is rotten here. I checked it in Firefox and they look identical, and both are wrong. Something has changed in the system.

AAAAARRRGGGHHHH!!!!!

Okay, weird:

I simply sent the photo out of Aperture into Photoshop CS3 beta and it asked me to convert to the working space, which is sRGB IEC61966-2.1. My camera is set to "sRGB" not Adobe as it's working space but for some reason Photoshop sees the incoming photos as Adobe RGB. What's going on?

Having just done that conversion, it looks better:

Pindy, we don't alter your photos There is no "built-in" color correction that is applied to your displayed photos.

Fire back any questions you have

Hi Andy, I was referring to the "i2e" that you use.

Yes, this is the page I was referring to.

I think what is happening is the export profile from Aperture was set to "sRGB" not sRGB 61xxxxx-2.1" and for some reason this seems to have a huge effect on the output.

i2e is our Auto Color correction at the lab, for prints, yes.

It's so strange. if you look at the "photo info" for both the photos on my SmugMug site, the info is identical except for the file size, as there's less detail in the intended photo. Both claim sRGB.
