From the 7th lesson, we will be introduced to oil painting techniques. As the first class of oil painting, we learnt from using a limited colour palette, to learn the treatment of the light and shade in monochrome. In the beginning, choose a dark colour such as burnt umber or ivory black as the main colour, mix with a small amount of turpentine to smear the canvas panel with a large brush, and wipe to get the surface even by tissue paper. The following painting steps for the composition, proportion, shadow shapes and values are the same as the charcoal drawings we learnt before. It was quite interesting to see how the drawing techniques can be applied the same on paintings.
The brightest parts can be rubbed out by tissue paper, for example in the fourth image below. When I rubbed the panel, I used the help of turpentine, because the panel I used was a cheap one I bought years ago. Tutor said that a good quality panel like Fredrix can be wiped out very easily, which it’s good to know that there are many elements can impact the results. The final look was finished by mixing with titanium white oil colour.
I specifically chose the male torso as my first practice, because I had been drawing the female torso and cast in my previous classes, which their outlines and shadows are very soft. The muscles of the male torso are much stronger, and the shadow shapes and body structures are much clearer. The result is easier to present, and it will make me feel a sense of accomplishment.
第七周的Foundation课程 – 我在London Fine Art Studios工作和学习的日子
从这节课开始就是油画色彩训练。作为油画的第一课，是先限定在用一个色为主来先学习明暗光影的处理。先选取一样深的颜色例如赭石或黑色作为整幅画的主色，混合一小点松节油用大笔刷涂抹画板，并用手纸擦匀。之后构图的步骤与之前的碳棒画不尽相同。
最亮的部分可以通过手纸擦揉出来，例如下面的第四幅图。因为我用的是自己以前买的便宜画板所以有些擦不出来，沾了一些松节油之后才能擦出。但是老师说如果是好的画板的话就可以马上擦出来的。阴影都处理好之后，就可以开始通过混入白色来完成最后的效果。
我特意选择了男性躯干像来作为我的第一个练习，因为之前一直画的是女性，线条和光影都很柔。男性躯干像的肌肉线条更加强烈，阴影结构更加清晰。效果更加容易呈现，效果会让自己很有成就感。
