When you metered this hall way

Where did you place the meter to get the shadow detail?

When metering really dark hallways I struggle with where to put the meter reading. I know everyone says meter where you want detail but when I do folks say it is too dark and they don't see enough detail. I can barely see anything right at camera left on your shot. Is there more in the print?

I would have metered right there, Camera left, and placed the exposure on the least amount of detail shadow. Just under zone three.
