Direct paper positive using weak 3% hydrogen peroxide with a little citric acid as bleach. This is a process that Ricardo Leite used to make film reversal and Joe VanCleave successfully used to reverse paper negatives, but with weaker H2O2. Re-developed with thiourea, skipping re-exposure.
I like the juxtaposition of the somewhat mundane grass foreground and the dramatic oak. Also the process sounds just about esoteric enough to give it a try.
