He is credited with having introduced the practice of painting with pigments that had been mixed with oil and flexible resins on canvas, which resulted in a luminous, jewel-like effect.
The result can be a luminous and magnifying effect not unlike peering through ice or a laboratory slide.
Of the open-ocean squids (oegopsids) such as Lycoteuthis, Histioteuthis, and Enoploteuthis, as many as 75 percent are self-luminous; i.e., light results not from symbiotic luminous bacteria but from an internal biochemical reaction.
Three different treatments of the same scene in St . Petersburgillustrate the variety of results, from luminous and translucent to bold and intense, that such a synthesis may yield.
Photometric data and digital images of the luminous environment are the results that are obtained.
The result is luminous in its imagery, highly sophisticated in its musical choices (the folk song I Know Where I'm Going succinctly and repeatedly stresses that they don't know anything at all) suffused with romantic fatalism – they'll die by night, too; you know it from the start – and enriched by Ray's total identification with his characters' doomed trajectory.
As a result, a luminous efficacy of ∼101 lm/W and a CRI of ∼83.1 were obtained for the mixed sample with 5 wt% red phosphor, which correspond to a decrease of ∼11.2% and an increase of ∼9.3% compared to the reference sample.
The results are intense, luminous and incredibly focused.
