Carving pumpkins is a time-honored tradition on Halloween. Though many people carve pumpkins with simple triangle eyes and noses, some people wish to make more elaborate carvings. Most stores sell premade templates and some can be downloaded for free online. But if you want to make a pumpkin carving stencil out of a picture or image you have, there is a little more work involved. Though it does take some effort and perhaps more than one try, with a little practice, almost any picture can be turned into a pumpkin carving stencil.
Things You'll Need
Photoshop or similar photo altering software
Ruler or measuring tape
Scan the desired image to your computer if it's not already on your hard drive.
Measure the side of the pumpkin you wish to carve on. This will guide you in how large your finished image should be. Write this information down and save it for later.
Load your photo altering software and start a new project by opening the image you wish to use.
Click on the "Image" menu in your photo altering software. In Photoshop, select "Adjustments" and then "Desaturate."
Click on "Levels of Brightness/Contrast" from the same "Adjustments" menu. Continue doing this until the image changes to as close to pure black and white as possible.
Posterize the image to three colors: pure black, pure white and middle gray. Do this by going to the Adjustments menu and clicking "Posterize" then "Levels: 3" from the menus. Your image will now appear in only these three colors.
Invert the image by using the "Adjustments" menu and clicking on "Invert." This will change the black to white and the white to black.
Save the new image to your hard drive and print it out. When printing, you may need to adjust the size of the printing depending on how big or small the pumpkin is. Refer to the measurements you took at the beginning of the project if you are unsure of how big to make the print.
A photo that already has a lot of contrast in it is ideal for this project, since it makes rendering the image into black and white easier.
The photo used for this project doesn't have to be of a high resolution since it is going to be rendered in black and white during the image altering process.
Images with too much small detail may make for fuzzy stencils that are hard to carve. For novices, it is best to begin with an image with only one or more objects in it that are large and easy to carve. Once these are mastered, more detailed images can be tried.
