Oakwood mill is a complete ruin, quite why it’s been deemed worth keeping up rather than being demolished is beyond me, when some magnificent structures elsewhere have been flattened. I didn’t even bother looking for a way in, I took a few externals and moved on to look at other stuff in the area. I quite liked this one of the gate though.
I’ve not done too much to this, local adjustments are tricky when you’ve an image that’s as complex as this in terms of foliage and gate detail. It’s more of an overall contrast boost really, but better for it over all.
