Nearly everyone loves a beautiful seascape. Many of us who like viewing them, also seek to paint them. And the satisfaction that comes from painting a seascape makes the effort worthwhile.
First, do you have the materials on hand? Are you seeking to use watercolor, acrylic or oils? Each medium has its strong points. Water color dries quickly and the brushes are easy to cleanse. Acrylic dries quicker than does oil, though not near as quickly as watercolors; but the color is less given to fading. Oils have a quality that makes them unique for painting, but they can take months to dry.
So make your choice if you have not already purchased the materials and let us get to the canvas. Any good craft store will have canvasses of many sizes, from the tiny to the gigantic. If you want a seascape for your desk or bathroom wall, you will naturally choose a smaller canvas. You might also consider one of medium size to practice the art before you try one the size of the wall above your sofa.
With your canvas on the easel, you will first want to paint in the sky. This is best done by making large x's over the top portion of the canvas. Carry the color, be it light blue, dark blue or some other hue of sky down below where you intend the water to begin. That will insure that you don't have a gap between the two sections.
It is usual to put in a few cloud formations and these can be simple or elaborate, depending on your personal desires. Load your brush with white paint and if using oils, make an area the basic size you choose, then with a blending brush, smooth out some of the lumpier spots until you achieve the desired result.
If you are using oils and are having trouble keeping the white areas as pure as you like, then wait until the paint of the sky has dried.
What color will your ocean be? Green as the Pacific or blue as the Atlantic? Either makes for a beautiful seascape. If you're in the USA and painting the Atlantic, are you in the north or down south? This can make a difference if you are painting what you see out your window or at the beach near where you live. Some seascapes include large rocky crags, others a more sedate beach without rocks.
Your sea will need to be horizontal across the canvas. Forget the way you put in your sky. Take your loaded brush and beginning in the air next to your canvas, use a sweeping motion and allow the brush to travel across the white space. Go beyond the other edge of the canvas, out again into the air. It takes some practice to achieve this one sweep motion, but stopping in mid sweep will cause a result that will not please you.
Continue with this sweeping action until you have covered the entire area that will be your sea. It will then be time to allow the oils, or acrylic paint to dry.
Once the paint has dried to your satisfaction, you may put in the waves to suit you. Again using a brush loaded with white paint, make the waves with the loaded edge of the brush, with a firm stroke across your water. For foam, these must be put in place with and upward loaded brush stroke and a dabbing on of paint on the tops of the waves.
It can be difficult to learn to paint seascapes from reading only, but with some experiments and practice, you can learn to make a pretty painting.
Don't forget to clean your brushes whichever medium you choose for your artwork.
