28 Critical Reflections: random 1 t0 7
The gallery is a lovely bright space, all white-painted wood and high ceilings, with a few stunning pieces, but the garden's the real show-stopper here. It's quite small, but full of amazing and very varied sculptures, placed far enough apart that you can enjoy each one individually, but close enough together that you can get really interesting perspectives of three or four at once.[8]
This can be explained by the existence of microfacets. We assume that surfaces that are not perfectly smooth are composed of many very tiny facets, each of which is a perfect specular reflector. These microfacets have normals that are distributed about the normal of the approximating smooth surface. The degree to which microfacet normals differ from the smooth surface normal is determined by the roughness of the surface. At points on the object where the smooth normal is close to the half-angle direction, many of the microfacets point in the half-angle direction and so the specular highlight is bright. As one moves away from the center of the highlight, the smooth normal and the half-angle direction get farther apart; the number of microfacets oriented in the half-angle direction falls, and so the intensity of the highlight falls off to zero.[6]
'Abstract' is a word which is now most frequently used to express only the type of the outer form of a work of art; this makes it difficult to use it in relation to the spiritual vitality or inner life which is the real sculpture. Abstract sculptural qualities are found in good sculpture of all time, but it is significant that contemporary sculpture and painting have become abstract in thought and concept. As the sculptural idea is in itself unfettered and unlimited and can choose its own forms, the vital concept selects the form and substance of its expression quite unconsciously.[7]
There is an inside and an outside to every form. When they are in special accord, as for instance a nut in its shell or a child in the womb, or in the structure of shells or crystals, or when one senses the architecture of bones in the human figure, then I am most drawn to the effect of light. Every shadow cast by the sun from an ever-varying angle reveals the harmony of the inside to outside.[7]
What alien/other peoples from other-worldly, past or future cultures would have made such a grouping of monolithic structures out of aluminium, brushed or stainless steel? The alien, the natural, the primitive, the advanced coincide in Hepworth's works and garden.[4]
River Form reminds the viewer of a pebble that has been gently shaped by the currents of a churning river. The piece is a contemplation of water, space and the sky. The artist’s interest in exploring the void and the interaction between positive and negative space is evident in the cutaway interior which gives the impression of having evolved over time.[1]
I like the contrast of foreground horizontal form with background vertical one, also between them the rhododendrons and lake with reflections.[5]
