Difference in color between full photos and thumbnails?

BeckmannPhotos

I noticed in my galleries that the thumbnails appear to be the correct color, or as I remember uploading my photos, but when I click on the photos to view them, the photos look off color, more muted, what is the reason for this? I am using a spyder 2 to calibrate my monitor, but am I doing something incorrect in outputting the files or working with them?

TIA

I don't understand why this was moved, this is a smugmug site question, not something related to color correction necessarily. I would understand this issue if both the thumbnail and larger image were both off in color, but they are not. Why is this the case since the thumbnail is derived from the original image I assume?

What browser are you viewing them in? What OS?

When I view your portfolio gallery in Firefox 3.6 on Windows Vista, I don't see any significant difference between your thumbnails and your main image. Both look vibrant to me.

Also, please correct the first link in your dgrin signature because it just takes one to the Smugmug homepage.

hmm, that's interesting, I'm at work now on a different computer and they appear correct. Surprises me that at home on my corrected monitor I have an issue and here where it isn't corrected I don't. At home I have windows 7, firefox latest version. Here I have vista and firefox 3.5.2. Any ideas?

You need to figure out if it's something local to your computer or something you're doing to your images. To that end, I guess I'd ask you to check some other people's galleries like this one on the home computer and see if you see the problem there of dull main images. If you do see dull main images on other people's galleries, then it's something you did when calibrating your home machine. It is possible to make mistakes in the calibration process and get the wrong profile set as your monitor profile. If you don't see issues in other people's galleries, then it's more likely something you did in preparing your own images.

This was moved because I believed that the question you asked is related to smugmug, not to your customization. Your customization doesn't render the thumbs/photos - smug does.

Hey Matt,

This is typically due to your color profile on your computer. SmugMug is a color-aware photo host, and with that we embed the sRGB color profile in all your display copies, Small and larger. Thumbnails do NOT contain the embedded profile. This is why you're seeing the difference.

If you can send me a link to a specific gallery and image showing the difference between thumbs and display copies, it'd help.
