In Forza Horizon 5, there were a lot of lens effects that in real photography only appear with some anamorphic lens and adapter designs, yet the options for the aperture shape in photo mode did not include any options to simulate the telltale oval bokeh that is associated with anamorphic lenses.
In Forza Horizon 6, it would be nice to have a few options for anamorphic bokeh, especially as this would allow for an appropriately cinematic look when framing photos for a 21:9 aspect ratio.
