Colour tone issues with Fujifilm Fin...

It sounds like the sepia tone is most likely caused by the tungsten lights in a regular room. Without flash, the only source of illumination indoors is artificial light (unless window light is dominant). There is a way to color balance the camera to approximate sunlight through the manual settings. Look in the menus for "white balance". You'll need to take the camera off of the fully automatic settings first. Move the cursor up or down while looking at the image and you will see the color shift. when you find a color balance you like for that particular room's lighting conditions, hit the OK to lock it in the activated position. Remember to go back to "auto" white balance for most shooting, especially outdoors, or everything will take on a wierd color cast.
