Have an image you want on a pumpkin, but don't have a pattern? No worries, send me the image and I'll generate a three-tone gray-scale pattern and you can start your carving masterpiece!
The best images to make gray-scale patterns from are ones with good contrasts. Old B/W images from Golden Era Hollywood are great examples. New photos are perfectly workable as long as they have contrast. For example, a picture of a child or pet is best if lighting is from one direction so there are contrasting shadows.
Ideally an image should be high resolution or at least 800x800 pixels in size. Smaller images or large low resolution images can work but they can be tricky. I will attempt to generate a pattern from whatever I'm sent but if I cannot because of poor image quality I will let you know ASAP.
