I am a very amatuer photogragher. I have a panasonic lumix dmc fz5pp camera. I have to edit all of my outdoor landscape pictures using fill light. They are very dark. Looking through the view finder or the LCD screen, they look good, but after transfering them to my computer I have to use the fill light. When I first used the camera I didn't need to do this. I usually use the scene(landscape) mode on the camera to take these pictures. Any suggestions? Also, Is there a free website that can teach me the basics of digital photyograghy? I have a natural ability for finding excellent scenes, but really need help on the technical part of photograghy. I would really appreciate any help. Thank you
