Trying out the LCW half-frame!

As I used an iso400 film, it beats me why some of the photos turned out so blue even in the outdoors with a lot of natural light - my sister's roll of iso800 on her Fuji Natura Classica turned out the same way. Could it be the fault of the photo lab's? Perhaps their scanner is faulty or not working at its best? Someone help me out!
