Photo Impressionism

Using film creates some effects that are "often imitated, never equaled" - one of them is grain. The grain filters in PS come close, but not quite the same.
Cross processing (slide film developed as negative) enhances grain. It helps to overexpose by about a stop.

I used the extinct AGFACHROME RS1000, overdated, rated at 400.

the original print was off color - I adjusted it in PS.
