油彩與塑膠彩的比較(20點)

the main difference between oil painting and acrylic painting is the overall feeling of the fininshed product. both types of paints have it's pros and cons. oil painting is used more for a smooth transition on the canvas while acrylic panitning can create texture and vivid brushstrokes.
Speaking from personal experiences, oil painting is difficult for amaterus, as it requires a lot of patience b/c you need to build up layers to create a realistic painting and each layer needs to be completely dry before the next layer can be apply on top. Also, if you are not use to this medium, it can create quite a mess, because the paint needs to be washed and thin down using turbitine.

Acrylic paints are easier to handle, they dry very fast and can be diluted with water, i think it is easier for a beginner to handle (but doesn't necessarily mean that it is easier to master). For impressionistic painting, i suggest acrylic because, as mentioned before, it is easier to creat brushstroke and because it's quick drying, it is easier for you to capture the both the emotion of your subject and also yourself on canvas.

of course, this is just personal opinion and experience.

塑膠彩快乾D, 同廣告彩相近~(如果油薄d ge話...)
但廣告彩ge遮蓋能力好d!
塑膠彩多數人ge用法,係好厚咁油上去~如油彩咁上下用法...
因為快乾~好快唔可以混色!
都因為慢乾! 想加野而混唔到下面d色要等乾時就好快~
乾咗之後痴塵可以用水抺~

油彩慢乾D, 臭D, 整係手上難洗D~
因為慢乾~耐d都仲可以混色!
都因為慢乾! 想加野而混唔到下面d色就要先等乾...會好耐~
而且會比較痴塵!但可以用水抺~

我個人比較like用塑膠彩多d!因為可以畫得快d...
but用乜顏料畫,其實都幾睇你可以熟用邊隻顏料!

要繪畫印象派作品就...
其實以前印象派作品多數係油彩,水彩,粉彩...
大概因為當時未有塑膠彩~ ^^

油畫和膠彩 最大的區分 在於 媒劑的不同，也就是說油畫是以油揉合色料，
膠彩是以動物膠提煉的膠質做媒劑。 前者屬油性，後者屬水溶性。

二者當然都能表現出立體感，這是沒有問題的。膠彩之所以讓你感到比較平面是因為早期膠彩在日本可說是他們的國畫(那時專指膠彩畫)，等於是中國的水墨的地位。但是膠彩和水墨的作畫歷程是一樣的，須層層疊染，並且注重工整細緻的美感，加上水墨和膠彩其實同出一軸，對於主題的處裡方式(ex對立體感的概念)沒有太大的區別。 至於會感到比較平，是因為本身材質特性輕薄的關係。
油畫顏料本身就是濃稠的，當然畫面會感覺較渾厚，深沉。
