The glass must be immaculate. Anything on it at all will ruin the focus, so scrub the inside with a sponge (always first) and wipe the outside with glass cleaner. Then try to reduce any outside light, any reflections will also ruin the pic. I wait until nighttime to take my pics. If you use a flash, take the picture at an angle to avoid seeing the reflection in your pic. Other than that, remember digital pics don't cost anything to take, so take as many as you want!
