I’m working on a painting of Haystack Rock in Cannon Beach, Oregon. It’s not quite finished yet, but I put together these images into a gif so you can watch the process of using masking tape to make a crisp horizon line.
If the gif isn’t working, here are the step-by-step images below:
I measured from the bottom on each side to get the horizon level, and applied the tape. Make sure your paint is really dry before putting tape on, at least 30 minutes, or longer if you are using blending mediums to slow the dry time.
Then, I removed the tape and let it dry:
Much better! I’m still working on this one and I’ll post the finished product soon.
