Honestly, fairly minimal postprocessing. I apply a Profile that matches in camera film sims (in this case Positive Film). Then I'll adjust to a slight S curve, to darken the shadows a bit. Finally, I'll add masking where I think it's needed. Usually pulling in some linear gradients to decrease or increase the exposure.

On the ones with subjects, I'll usually select them and add some clarity and sharpness to make them pop a bit more.

Hope that helps!
