I want to know if it is possible to change the grid layout on the D5000. The default comes up with 16 squares in a 4X4 layout. I want a 9 square layout in 3X3 to use the live view to set up rule of thirds in my photos. The manual is no help and so far I have not been able to find a way to do it. Does anyone know how/if it can be done? Thanks.
