How to add grid to photos on the Samsung Galaxy S4?

I have a samsung G4 and I would like to know how to add a grid to the photos I shoot. Also how to make the photos just black and white to see the values. 




Looks like both features you are looking for doesn't exist on the preinstalled camera app of Samsung Galaxy S4. I suggest installing 3rd party camera apps which you can easily find on Google Play store.
