If, on the other hand, changing the PPI to 300 has shrunk your image below 10 inches on one side, you will need to resample the image. If the image has a height or width of at least 10 inches, then you can save your image and you are finished! In order to change the size of the image, in Photoshop, go to the Image Size box (Image -> Image Size).įor most circumstances, deselect ‘Resample’ and then change the resolution to 300 Pixels/Inch. (higher PPI = smaller image in inches larger image in inches = lower PPI.) Please make sure that when you change the PPI that the size of the photo does not go below 10 inches on the longest end of the image. The basic issue you’re going to run into when increasing the quality of images is that the image will get smaller, because the amount of data in the image needs to stay the same. Here are some instructions for how to do this in Photoshop (available at computers in the Scholarly Commons, Room 220 Main Library):

We ask for a higher PPI/larger size because the winning submissions are printed out as large posters and we wouldn’t want your image to be very pixelated in case it is displayed. Your image needs a resolution of 300 PPI and a height or width of at least 10 inches.
