Sorry if this is the wrong place to post this but am a beginner dig. camera user and have some questions. I have a Fujifilm F810 and am having problems with it. Can't figure it out by the manual- all of my outside pictures are showing up white- and the inside one's have wavy lines going through them. From what I've read- I need to change the exposure and/or shutter speed- but for the life of me I can't figure out how to do that. Please help!
