Fields that consist only of "empty" lines will get boring after a while, so it's a good idea to think of nice pictures the dominoes could "draw". But in that case, you need a plan on paper since nobody can build domino images from their head. So how is such a plan created? The solution is simple. All you need is the well-known programme Paint which should be available on every computer. There are three different ways to plan a field, all of which I'll explain now step by step.
First, open the programme and use the "zoom" tool there. The zoom is important for being able to place the single squares correctly. The next step is clicking on the "brush" and setting it up to paint big squares. Once you've done that, you can paint a grid. Between two squares, you always need to leave lines of empty pixels. Like that, you get little boxes. You should end up with a grid like the one in the picture.
You can also enlarge that grid as big as you want. Now the key tool comes into play: the color filler. With its help, you can color the boxes the way you want. That's how the fieldplan on top of this page was made. It's not the last step for planning an actual complicated image or even portraits of people. Read more under "Special field plans".
It is important to keep in mind how to use that field plan. Every square contains two dominoes. That means that if you a line of five squares of length, you need to set up ten dominoes. But if you're watching the wideness of the field, one square is just one domino.
The second method isn't really different from the first one. As you plan every single domino here - while the first method always takes a square with two dominoes in one step - the result will be twice as detailed using the same number of dominoes. You don't use squares in the plan anymore now, but rectangles (see picture).
On TimDomino's homepage, you can download the field planning programme he created. You will also find detailed step-by-step-instructions on how to use it. The wonderful tool "field protocol" makes it much easier and faster to build a field than the other methods because it counts the different colors of dominoes in each row for you. Combined with the other two, this tool is just the best.
