I received a batch of images from a photographer and I wanted to reduce the dimensions of a couple, so I opened them up in Photoshop. They looked fine - the color was good, but when I went to save for web, the preview was brownish...like much of the color is sucked out and the image is darkened and lifeless.
I've been using Photoshop for web development and light editing for over a decade, but I'm not sure what is causing this. Perhaps some setting photographers use that I'm unfamiliar with?
In the photo below you can see the original (within Photoshop) above, and the "Save for Web" preview in the forefront.
