    10 Oil Painting Tips for Beginners


    1. Start with small paintings (Lúc đầu chỉ vẽ tranh nhỏ)

    Painting Small gives you the chance to try out techniques and experiment with color without investing too much time or material into the process. You can buy some small 8x10 inch canvases or canvas boards, or even try painting with oils on paper.
    Vẽ nhỏ cho ta cơ hội thử các kỹ thuật vẽ và chiêm nghiệm màu mà không mất quá nhiều thời gian hay vật liệu cho chuyện này. Bạn có thể mua một canvas nhỏ 8 x10 inch hoặc bảng vải, hoặc thậm chí hãy thử vẽ sơn dầu trên giấy.

    2. Get Organized (Bày biện ngăn nắp)

    Set up a space in a well-ventilated area where you can keep your palettes and supplies out and your paintings visible.This will give you the chance to see and think about your work, even if you're not actually painting. It will also make the process of painting easier so that you will be inclined to paint more often, even daily if possible. Your work will improve rapidly if you paint a lot.
    Dọn một chỗ thông thoáng, có thể bày biện palet và đồ vẽ và nhìn thấy tranh. Làm vậy sẽ cho bạn cơ hội để nhìn thấy và nghĩ về tác phẩm của mình, dù không vẽ. Thế cũng sẽ làm việc vẽ tranh dễ dàng hơn khiến bạn vẽ thường xuyên hơn, nếu được thì ngày nào cũng vẽ. Nếu vẽ nhiều, bạn sẽ vẽ đẹp nhanh dần.


    3. Invest in Brushes (đầu tư tiền mua cọ tốt)

    Buy professional grade paints as you can afford them rather than student grade.
    Nếu có tiền thì mua màu chuyên nghiệp, đừng mua màu dành cho sinh viên.

    Buy only a few
    higher quality brushes
    - three different sizes should be good to start with. You can buy more and experiment with the different shapes as you paint more.
    Chỉ mua ít cây cọ chất lượng cao - lúc đầu 3 cỡ là đủ. Sau này vẽ nhiều , thì hãy mua cọ các kiểu các dạng khác.

    4. Prime Your Painting Surface (sơn lót trước)

    It's important to apply a type of primer called gesso to the painting surface to prevent the oil from seeping into the surface, protect the surface from the acids in the paint, and provide a surface that the paint will adhere to more easily
    Cần sơn lót bằng loại sơn có tên là gesso lên mặt tranh để dầu không thấm vào mặt tranh để không bị axit trong sơn dầu ăn, và cho ta 1 bề mặt dễ ăn sơn hơn.

    5. Understand Color and Color Mixing (hiểu màu và cách trộn màu)

    Primary paint colors are not "pure" but rather lean toward either yellow or blue, making them warm if toward yellow, or cool if toward blue. This influences how the primary colors mix to produce the secondary colors.
    Màu sơ cấp không "tinh khiết" mà ngả vàng hoặc xanh, làm màu sơn ấm bằng màu vàng hoặc lạnh bằng màu xanh. Điều này tác động đốn màu sơ cấp khi trộn màu để có màu thứ cấp.

    6. Use a Limited Painting Palette (dùng ít màu)


    Don't feel that you have to use all the colors in your painting at once. Start with a monochrome painting, a painting of only one hue plus its shades (black added) and tints (white added). You can use any color you like depending on whether you want a cool or warm painting. This will allow you to get the feel of the paint.

    When you are ready, add a warm and cool of each primary color to your palette, along with earth tones like burnt sienna, burnt umber, and yellow ochre.

    Đừng cảm thấy mình phải vẽ bằng màu liền. Hãy bắt đầu vẽ đen trắng, chỉ có một màu và các bóng tối (thêm đen) và sắc thái (thêm trắng). Bạn muốn dùng màu nào cũng được, tùy bạn thích tranh theo tông ấm hay lạnh. Làm thế giúp bạn cảm nhận được sơn.
    Khi đã sẵn sàng, hãy thêm độ ấm lạnh của từng màu sơ cấp vào palet, cùng các tông màu đất như burnt sienna, burnt umber và yellow ochre.


    7. Start With an Oil Sketch (Bắt đầu bằng cách phác thảo bằng sơn dầu)

    This is a thin underpainting consisting of a color and turpentine (or odorless turpentine substitute such as Turpenoid). This will dry quickly so that you can then add subsequent layers of paint and color without having to wait too long for it to dry. Burnt sienna is useful to lay out values and composition, whether you work on a white canvas or tone it with a neutral gray first.

    Đây là lớp sơn nền mỏng, có màu và nhựa thông (hoặc nhựa thông không mùi như Turpenoid). Làm vậy sẽ khô nhanh để bạn có thể vẽ lớp nữa và thêm màu mà không cần phải đợi cho khô quá lâu. Dùng Burnt sienna để bố trí các value và tạo bố cục tranh, dù lót bằng màu trắng hay màu xám trước.

    8. Understand Paint Order (Biết thứ tự vẽ)


    Paint thick over thin, fat over lean, and slow-drying over fast-drying. That means using thinner paint and less oil in the first layers, saving thicker paint and higher oil content for later layers. This will help ensure that earlier layers dry first and will help to keep your painting from cracking.

    Start with an underpainting of paint and turpentine, then move to a painting medium of a combination of turpentine and linseed oil in a ratio of 2:1. Linseed oil can yellow with age (which is more apparent on light colors) but dries faster than other oils.

    Hãy vẽ dầy lên mỏng, béo lên gầy, và chậm khô lên mau khô. Nghĩa là dùng sơn mỏng và ít dầu làm những lớp sơn đầu, để sơn dầy và nhiều dầu sơn sau. Làm vậy sẽ đảm bảo lớp trước khô trước khiến tranh không bị nứt.
    Hãy bắt đầu cách sơn nền bằng sơn màu và nhựa thông, rồi tiếp đến là medium vẽ tranh là hỗn hợp nhựa thông và dầu lanh với tỷ lệ 2:1. Dầu lanh lâu ngày có thể ngã vàng (màu nhạt sẽ thấy rõ) nhưng khô nhanh hơn các loại dầu khác.



    9. Clean Your Brush (rửa sạch cọ)


    It's important to clean your brush between colors and with soap and water when finished painting. Oil painting can get messy. Have paper towels and rags handy to wipe excess paint and turpentine off your brushes. Have two containers available while painting - one for turpentine for cleaning your brush between colors and one for medium to mix with your paint.
    Cần rửa sạch có bằng xà phòng và nước sau khi vẽ xong. Vẽ sơn dầu có thể làm ta bẩn. Hãy luôn có sẵn bên tay khăn giấy và giẻ để lau sơn và nhựa thông thừa ra khỏi cọ. Hãy chuẩn bị sẵn hai hũ khi đãng vẽ: 1 để rửa cọ và 1 chứa medium trộn màu.


    10. Keep It Tidy (Hãy gọn gàng ngăn nắp)

    Oil paints and mediums are toxic if ingested or absorbed into the skin. Keep them put away and out of reach of pets and small children. Dispose of paints, mediums, rags, paper towels, and disposable paper palettes or paper plates (also good to use as palettes) properly. You should wet or soak rags and paper in water before discarding them since they are flammable, can heat up when drying out, and sometimes spontaneously combust.
    Sơn dầu và medium độc nếu nuốt phải hoặc dính da. Hãy dẹp gọn hoặc để ngoài tầm với của thú cưng và trẻ em. Hãy vứt đúng cách sơn, medium, giẻ, khăn giấy, và palet màu bằng giấy dùng một lần hoặc đĩa giấy (dùng làm palet cũng tốt). Hãy ngâm giẻ, giấy trong nước rồi hãy vứt, vì chúng dễ cháy, khi khô có thể nóng lên rồi có khi tự cháy luôn.

    Re: Học vẽ sơn dầu - oil paintings for beginners

    Glazes and Washes Go Over Dry Paint

    TRANSPARENT layers of oil paint are called GLAZES.

    TRANSLUCENT layers of oil paint are called WASHES.

    Both are colors thinned with a solution of 1/3 linseed oil, 1/3 turpentine and 1/3 Damar varnish.


    A GLAZE is a thin TRANSPARENT color used over another dry color to create a third color. For example if you put a thinned Quinacridone rose (a transparent color) over blue, you get a violet. If you use a glaze over a similar color you enhance the color. Cast shadows over complex textures are often glazed. A glaze always darkens a color. (See Paints for transparency and opacity)


    This is a Glaze


    By example, the beetle's carapace needs to be greener.

    The GLAZE formula is mixed on the palette with thalo green (a transparent color) until the degree of transparency necessary is achieved.

    The glaze is then applied with a sable brush to the horizontal painting. Allow it to dry overnight. With a glaze you can change a color with out changing the pattern of brush strokes of the underlying layer of paint.
    This is a Wash
    A WASH is a thin OPAQUE color used over another dry color. A wash will not change its essential color and appears as a TRANSLUCENT layer on top of other colors.

    Mix the color with the glaze solution on your palette until you have the degree of translucency needed. Apply it to the horizontal painting with a sable brush.

    White (an opaque color) is used with a glaze solution to create the rays of light. Allow it to dry overnight.

    Oil Painting Tips For Beginners


    Oil Painting Tip 1: Paint Fat Over Lean


    This is probably the most important rule of oil painting, especially if you are painting wet on wet (a technique where you do not let the paint dry in between layers).
    Fat paint refers to how much oil is present. By adding an oil medium to your paint, you are making it fatter. By adding a solvent to your oil paint, you are breaking down the oil and making it leaner.
    The fatter the paint, the slower it dries.
    The reason for painting fat over thin is that the layers on top must dry slower than the layers on the bottom of your canvas. If not, the paint will crack as it dries.
    A simple way of tackling this is to have a process for painting. Start with very lean paint (paint plus solvent). Then add layers which are slightly fatter (paint plus a mix of solvent and oil medium). Every subsequent layer should be fatter than the prior (more oil medium / less solvent).
    Personally, I use Winsor & Newton Refined Linseed Oil to fatten my oil paint and Mona Lisa Odorless Paint Thinner to thin my paint.







    Oil Painting Tip 2: Paint Thick over Thin

    This is a similar principle to the fat over lean rule, in that it is based on the drying time of oil paint. Thick oil paint dries slower than thin.
    So in theory, your first layers should be very thin, almost glazes of paint. Then as you build up your painting you be adding increasing amount of substance and oil.









    Oil Painting Tip 3: Prepare Your Canvas

    Preparing your canvas is a commonly overlooked but very important step. What does it actually mean?
    Well firstly, you must make sure your canvas has sufficient gesso coating. This is generally the case for most pre-primed canvas you buy from art stores.
    Next, you should consider laying down a muted background color for your canvas (I like to use Winsor & Newton Winton Oil Colour Tube, 37ml, Raw Umber). This achieves the following:
    • It gives you more of a middle ground to work with on your canvas, rather than a glaringly white canvas. Painting straight onto a white canvas could wrap your sense of values.
    • It avoids any bare white parts of your canvas being exposed.
    • It is an easy way to just start your painting and stops you from procrastinating, waiting for the perfect time to strike the canvas.
    Now that you have a colored background layed down on your canvas, you should consider placing a sketch for your composition.
    The sketch does not have to be all da Vinci. All it needs to do is set out the major shapes in your composition.
    The purpose of the sketch is to merely guide you around the canvas. A sketch is also particularly useful if you are dealing with any perspective lines in your painting (i.e. a cityscape).









    Oil Painting Tip 4: Try Painting With A Limited Palette

    More colors does not mean a more sophisticated painting. If anything, it is often the opposite.
    In your next painting, try limited your palette to the bare essentials of blue, yellow, red (the primaries) and white. By mixing the three primary colors you get a natural black. Add some white to that and you have gray. The three primary colors can then be used to mix what-ever color you need.
    Using a limited palette will help focus your painting and create harmony. The more colors, the more difficult it becomes to balance your painting and control the chaos.






    Check out these oil painting tips perfect for beginners.

    "Kvinna som klär sig", Anders Zorn, 1893




    Anders Zorn was known to use a very limited palette of Yellow Ochre, Cadmium Red Medium, Ivory Black plus White. This is often referred to as the Zorn palette.

    The Ivory Black was used by Anders Zorn as a very dark blue and the Cadmium Red and Yellow Ochre made up all three of the primary colors. With the addition of white, he was able to create a broad range of colors but retain a harmony across his paintings.


    You can read more about Anders Zorn here:









    Oil Painting Tip 5: Upsize Your Paint Brush

    A simple way of improving your painting technique is to take the largest brush you are comfortable using, and up-sizing it. Try using this brush for a long as you can brush downsizing to smaller brushes.
    A large brush has such influence in your painting and forces you to be decisive and efficient with your strokes. You will also be able to cover the canvas much quicker.












    Oil Painting Tip 6: Your Palette Knife Is Not Just For Mixing Colors

    Palette knives are not only useful for mixing colors on your palette. They can be a fantastic painting tool used for applying paint in an impasto style, or for scraping paint off your canvas.
    You can also use palette knives to put paint on the canvas without any blending which you would get from using a brush.
    There are some artists who have left paint brushes behind entirely in favor of palette knives.

    Oil Painting Tip 7: Learn Global Techniques You Can Use In All Your Paintings


    Instead of spending all your time learning how to paint a specific beach scene, type of tree of cloud formation, invest in learning global techniques which you can use in all your paintings.
    Great painters have mastered a handful of techniques which they use over and over again in all their paintings. Learning how to paint a highly specific scene will teach you exactly that, but nothing more.











    Oil Painting Tip 8: Incorporate Scraping

    Instead of adding more paint to create objects in your painting, try scraping paint off your canvas. This is a create technique for adding texture, detailing trees or even just for signing your painting.
    You can use the blunt end of your paint brush or palette knivesfor this technique.









    pro hartSave

    Pro Hart, Australian Painter




    Pro Hart was a famous Australian painter who used scraping in many of his paintings, usually to depict the harsh and sketchy Australian environment.







    Oil Painting Tip 9: Careful with Blending


    Blending is a common technique used in oil painting to create a refined and smoothed appearance. It is particularly useful for pushing objects back in perspective by softening the edges into the background (i.e. distant mountains which blend into the sky).

    With that being said, it is one of the most overused techniques in oil painting. This is likely due to those painters trying to create a realistic finish as they view the painting from close. But you should not be painting for people to view up close. You want them to see the painting from a reasonable distance.
    Your brush strokes should be visible up close, but as you step back from your painting, there will be optical blending and those strokes will no longer be clearly visible.
