This effect was achieved entirely in-camera. I arranged the matchsticks as they appear in this photo. Then I focused on the four innermost matches. I set the exposure to be 1.3 seconds(at f/11 and ISO 100) and zoomed out as the shutter was open.
Optical Illusions + If you view large, and scroll up and down, it appears as if the matches are bending + If you stare at the center for long enough, it appears as if the center is expanding
Thanks for sharing this with the group ryotnlpm. Happy New Year!!
