Scaling Up an Image with Shelley Holtzman
Scaling Up an Image with Shelley Holtzman
To enlarge a painting or image that you would like to draw or paint without a projector is easily done using a grid. It’s not too difficult, but it does take a little math. The key is to keep the proportions of your reference image and work surface the same so there will be no distortion. For example, if you reference an image that is an 8×10, it will easily enlarge to a 16×20, 24×30, etc.
Draw a grid of equal squares over your reference photo. For an 8×10 image measure with a ruler and make a small mark every inch on each side. Then proceed to connect the marks to create a grid! Use a pen so the lines stand out.
2) Number the squares across the left side and top of the reference photo.
3) Use the same technique to draw a grid of equal ratio on your paper lightly in pencil. This is a 2” grid because the final piece is 16×20. (For a final piece that’s 20×25 your grid would be 2.5” and so on.) Number the large grid accordingly.
On canvas use a soft charcoal, which can be sealed with a fixative or washed off with water after you start painting.
4) Now the fun part! Begin to copy your image square by square. Focusing on one square at a time is easier and less overwhelming than the entire image. Make sure you are in the correct square! Use the numbers on the sides to guide you.
5) EXTRA TIP: Cut a frame to the size of the squares on your reference photo to help stay focused!
Keep drawing!
