Part of the incredibly sad railway building works at La Sagrera, Barcelona (incredibly sad, because as with so many construction projects here, they are currently “paused” thanks to appalling failures in the cost estimates and budgeting).

Part of a test series for Ilford Delta 400 pushed to EI3200 in Microphen with one-stop over-exposure. Shot with the M7 and ZM 2/35 in full daylight using a deep red filter.

Here the sky is darkened by the red filter, but there seems to be a lot more grain in the sky than I would have expected based on the previous test shots. I am not sure what the cause of this is, but it is perhaps related to the response of the film to extreme low frequency light when pushed in this way.
