Using the photo inspection to find the best available photos
In order to find the best photos that correspond with a location on a point cloud or mesh, select the crosshair icon (1) and then select the desired point in the viewer (2).
By default, the photo viewer will then show the best five photos covering that point (3). This can be decreased or increased by navigating to the cog wheel next to the "Close photo viewer" (4).
POIs can be created that links a photo to that selected point (5).
At the top of the image are the zoom in, zoom out, reset view and enter full screen buttons (6).
