When cropping in Lightroom it will helpfully overlay the image lines marking thirds, which makes it easy to crop using the Rule of Thirds.
Is there any plug-in/add-on or other means to instead overlay with lines marking the Golden Ratio, or with a Fibonacci Spiral?
LR has an option to cycle through the various grid overlays for cropping, including the Golden Ration, Fibonacci Spiral and others.
In the Develop module, select your photo.
Click on the "Crop" icon from the right-side panel (it's the first one on the left).
Press the letter "O" to cycle through the overlay options. Or select in the Tools >> Crop Guide Overlay submenu.
For overlays that have different center points press Shift-O to cycle through those.
