I uploaded a batch of new photos to Flickr, pics from my visit to DC. I tinkered with the white balance and exposure of the RAW files before using ImageReady to convert them to JPEGs for upload.
When I looked at the photos in ImageReady, the colors looked washed out as compared to the more saturated RAW files I had been working with. I should have stopped and investigated then. It wasn't until today that I found the source of this problem. Sigh. Perhaps they won't look washed out for you Windows PC users. I changed my Mac display gamma to 2.2; I like my world's color palette rich and saturated. Sometime I'll have to go back and correct these photos.
