Here is a collection of various studies with different media and supports. Most of them were produced as preparatory drawings. However, I feel worthy enough to regard them as proper works. The preparatory drawing is my essential process, particularly when I produce historic figure portraits.
Some artists produce numerous preparatory drawings over a period of time while others proceed to produce works directly. Some use photographic images to test out the composition, develop ideas and embody creative inspirations. Leonardo da Vinci could be the earliest artist who used camera obscura for his art practice. More than a century later, Johannes Vermeer and Giovanni Antonio Canal, known as Canaletto were said to use this device proactively. Francis Bacon and Andy Warhol were both well known to use photographic images for their art practice in the modern era. Nowadays I often develop the idea through digital manipulation of my original drawings and pictures. The definition of "preparatory drawing" blurs, so does these works. Some of them are complete and ideal in their own rights while some works regarded as completed but I've never been satisfied. It can be said that the artist's life is the very nature of preparatory drawings towards more complete.
