Returned to the Henry Moore Garden with a plan. Of sorts. Take documentary-like images of whole sculptures, large partial-forms and textures, then create a panel with a coherent composition. I’m satisfied with this. It works well to composite everything, then find a high-contrast black-and-white treatment, and bi-colour-process that with bronze-like user-defined colours.
For the record:
Large-form in photoshop layer.
Texture in another layer.
Change blend mode to overlay, though sometimes something else.
Adjust both layers’ levels to taste.
Flatten or export, then black-and-white process with an appropriate filter for dynamic range.
Nik ColorEfex user-defined bi-colour process with colours picked from the original bronzes.
Print-to-file in lightroom as panel.
