In the 1960s, the Albright-Knox wrote to a selection of artists to ask for statements about their works. Victor Pasmore responded with thoughts about his 1960 painting Abstract in Red, No. 3.
No, you’re not imagining things; the right-hand edge of the prominent red shape in Abstract in Red, No. 3, 1960, is intentionally meant to look out-of-focus. The visible blurriness is one of the “expanding effects” artist Victor Pasmore used to create “ambiguous images” that “transcend the boundaries and dimensions of the finite picture-plane.” He explained that “to get beyond dimension in terms of strictly dimensional material poses a paradox which, in reality, can only be solved in subjective terms; that is to say, by stimulating the imagination. To do this within the terms of surface-bound painting has been and still is my problem.”
