Transcript Measure and use a grid to enlarge an image

BASIC
DRAWING USING A GRID
• Using a grid is a time honored way to
begin to understand how to render what
we see. It helps us to train our eyes to
see in a different way. After a while you
will be able to see the grid in your mind
without drawing it. With the grid system
you can make your drawings any size
that you want just by enlarging the size
of the squares in your grid.
Purpose of a grid drawing
• When artists need to enlarge
an image they often use a
grid. This grid enables the
artist to identify details in a
block and place them
properly on the page. Once
completed, all the blocks of
the grid form the larger image
Assignment
• Use a grid to draw a
larger version of an
image (your computer
photograph).
Step 1
• Draw a 1/2" grid on your
image.
Step 2
• Fold large sheet of drawing
paper in half and crease the
fold.
Step 3
• On the inside sheet of paper
draw a 1" grid. Have the same
number of squares in each direction as the
grid on your image has. 3x4 = 9x12
Step 4
• Fold the paper again. You
can see the grid through the
top sheet of paper.
Step 5
• Now make a larger copy of
your photograph by drawing
exactly what is in each
square
