Corne started to draw at age three and ever since showed an interest to paint.
Inspired by old master painters worldwide and especially South African impressionist Adriaan Boshoff. He has loved the works of the great masters ever since he can remember. Corne spent hours studying the works and techniques of the masters of impressionism, including Monet, Degas and Renoir.  The methods of composition and lighting, the use of broken colours to depict visual impressions, everything intrigued me, no end, he says.  There were also the techniques that he would explore in his own work.  It became an obsession to develop his own unique style based on the established disciplines of the old masters.
Corné was privileged to live with Adriaan Boshoff for one year at Hartebeespoortdam before his tragic death. The hours spent together at Boshoff `s house talking about colours and lines, different strokes, sketching the same thing over and over for hours paid off.  Although I see Boshoff as my mentor, I had to do the hard work of applying what he told me, and there was no easy way out. I draw and paint everyday and know that practice makes perfect.  I wish I had more time with Boshoff but I must rely on my own talents, and gifts that were given to me by the Lord.
An exhibition in Cape Town (June 2007) was a huge success. The Cape received Corné and his art work with open arms. Twenty five of his works of art were sold within hours of the opening speech delivered by Dr Franklin Sonn (former SA ambassador in United States of America).  A record price of R60 000 was paid for one piece. This makes Corné (30 years old) one of the youngest SA artists who has achieved such a goal.
He is a name to watch out for in the future. Corne's amazing quality of art is nothing short of a miracle. Weideman's works are displayed in some of the country's top Art Galleries.
