Updated spreadsheet & GRD files. The new version puts everything on two tabs - revised & original so you don't have to edit every tab if you want to try different aspect ratios.
If shipwrights disease really sets in, I suppose that I could add a macro to export the various .GRD files automatically. Hmmmm ... probably not.
I also added the two missing GRD files from the previous post. I even figured out what the photo_id.grd file is for! If you rotate the camera 90 deg you can use it to allign pictures of people's heads with the requirements for passport photos.
Also, if you press the DISP button until you get an LCD display with a minimum of Canon OSD stuff, the grids are a lot more usable in shooting mode.
@reyalp : this is not really G16 specific? Can you move the grid posts from this thread to
Grids : issues and challenges? TIA.
