When I uploaded this image to iStockphoto a month or two ago, I didn't think it was too yellow. But when I was visiting one of my relatives, I checked it out on his computer. And it looked almost too yellow. Perhaps, it was just his monitor. Stockxpert rejected this image because of the yellow tinge, but iStockphoto accepted it. And it has sold a couple of times on iStockphoto, so it can't be that bad(hasn't sold on Stockxpert yet). Thanks for your critiques.

If I didn't know better, I would think this was a commercial for "Calibrating your Monitor".
...I often wonder sometimes, if reviewers are required by those that hire them, to have their monitors calibrated properly.

yeah i agree, their monitors should be color calibrated, but i don't think any of the agencies require that.

But either way, even if you don't have a calibrated monitor, you can see if the white is white by looking at the numbers when you edit an image yourself in photoshop.
