Oil painting refers as a painting with pigments that are bound with a medium of drying oil — especially in early modern Europe, linseed oil. Often oil such as linseed was boiled with a resin such as pine resin or even frankincense; these were called ‘varnishes’ and were prized for their body and gloss. Other oils occasionally used include poppy seed oil, walnut oil, and safflower oil. These oils confer various properties to the oil paint, such as less yellowing or different drying times. Certain differences are also visible in the sheen of the paints depending on the oil. Painters often use different oils in the same painting depending on specific pigments and effects desired. The paints themselves also develop a particular feel depending on the medium. There are lots of oil painting website available in internet such as Pix2Paint. The process of oil painting varies from artist to artist, but often includes certain steps. First, the artist prepares the surface. Although surfaces like linoleum, wooden panel, paper, slate, pressed wood, and cardboard have been used, the most popular surface since the 16th century has been canvas, although many artists used panel through the 17th century and beyond. Panel is more expensive, heavier, harder to transport, and prone to warp or split in poor conditions. For fine detail, however, the absolute solidity of a wooden panel gives an advantage.
