I thought I’d try the HDR feature on a rapidly moving train. Here one of Amtrak’s Keystone trains is passing Princeton Junction at speed. Notice the effect of double exposure where the cab car is ghosted into the coach. This is curious aberration, but probably not the best solution for railway action photography. I don’t have a ‘non’-HDR image of this scene. Princeton Junction, exposed with Lumix LX7 in HDR ‘scene’ mode.
