Pixilu Imaging Inc. provides professional retouching services as an online service. You upload digital photos and Pixilu’s graphic artists review each photo and perform color correction, acne removal, facial lines reduction, teeth whitening, and enhanced red-eye correction. The cost varies from $1.49 to $9.99 per photo.
I submitted my picture to the service, and this is the “after” picture from the $9.99-level process. You can see what the artist did at this mouseover page.
