I recently purchased a Nikon D70s and so far I am very pleased with the camera. However, after shooting many pictures, experimenting a bit, I loaded them on the PC and noticed that many of the images had a blue tint to them. These were taken outdoors as well as indoors with the flash. I am using an older Nikon AF 35-80 lens off of my N70 and it has a basic UV filter attached. Any suggestions on what could be causing this.
