At some point, objective images teeter on non-objectivity. For example, if one looks only at the sky, isolating it from other representational things like the horizon line or buildings, on a clear day, it recalls a color-field painting. These highly abstract paintings are usually regarded as meditative and bring to mind concepts like sublimity and nothingness, aspects of visual experience hardly representable or objective.

For better or worse, photography is associated with objectivity. If photographs of the sky are printed on canvas and overlaid with paraffin, perhaps they broach the scarcely representable, or effable, concepts that Rothko and Klein were after.
