You are a retard, and are conflating metering and exposure. The first image is obviously correct and the second is BTFO. The first one is metered for the scene and the second is metered for the ground.
The beauty of neg film is that of course it's easy to fix a lot without it looking like shit, but you will end up with naturally better looking photos if you use the film's contrast curve rather than abitrarily wrestling your own onto it in post.
