He hopes his latest exhibition of nearly 70 works, most of them done in the past 10 years, can help people understand that the nude is a form of art. “In fact, it is the most basic form which all artists should study,” he adds.

His show illustrates how the female body has been a dominant creative force in his works as seen through his line drawings, paper collages and his more recent colourful abstracts, such as in Three Graces (2007) and Colour Poetry 1 & 2 (2003), which show a delicate interplay of different elements and balance of colours.

He also uses a wide range of painting media including colour pencil, ink, conte, pastel, charcoal, acrylic and a mixture of them.

The exhibition also features his newer experimental works that he has produced in a tedious process combining hand drawings and computer technology to create a new form of visual expression he calls pixelated mosaics. Examples of these include Pose V and Pose III both done in 2010.

After his return from his studies in Canada in 1970, the Raffles Institution alumnus taught at the former Baharuddin Vocational Institute for 10 years between 1972 and 1982 to train Singapore’s pioneer batch of graphic design artists. The school was the only one offering such a course then.

Later, he started his own advertising and design house, Loh Design, before joining Lasalle College of the Arts where he pioneered its design curriculum as dean of its design department between 1992 and 1995.

He later taught at the Raffles Design Institute, Temasek Polytechnic and life drawing classes at New York University Tisch School of the Arts Asia.

He was an active member of the Art Group 90, a group of artists interested in nude drawings, from 1990, when it was formed, to 2013, when it disbanded.

“I still like drawing nudes and hope more people can distinguish between nude and being naked, and they will appreciate what I do better,” he says.
