First of all, enable the visibility of the grid overlay in the Viewer by selecting the Mostra option in the Griglia tool.
Alternatively, go to the menu and select Visualizza -> Griglia to toggle it on and off.
You can also use the keyboard shortcut Сmd + G (masOS) or Ctrl + G (Windows).
Select the desired type of grid from the Tipo drop-down menu in the Griglia tool. There are three options available:
- Rettangolare. This is the default option that will let you customize the numbers of sections within the Grid with the Margine Lingo and Margine Corto options. Any number of equally spaced vertical and horizontal sections up to 128 can be chosen. The default is a 3 x 3 section grid.
- Sezione aurea. This 3 x 3 grid has been modified by the Golden Ratio rule so that the intersecting lines are closer to the middle of the frame. This grid has no options.
- Spirale di Fibonacci. It is a well-known tool to obtain an aesthetically-pleasing composition. You can control how the spiral grid is positioned over the image by flipping it vertically and horizontally.
You can select one of the six available grid colors to ensure that the grid will be easy to see against the image subject. You can choose between black, white, red, yellow, magenta, and cyan by Colore in the Griglia tool or by selecting Vizualizza -> Colore Griglia from the menu. The default color is white.
The Segui Ritaglio option will fit the selected grid inside the crop area and follow it as you readjust the crop. If the option is deselected, the grid will fit the entire image regardless of the chosen crop.
