Scientific photographic photos

The two photos are almost indistinguishable, and you can't even tell them together. The photos taken by Ron Ri *** an and Eric Gendron are so similar that a stranger thinks that one of them has been stolen.

Ron Ri *** an wrote for the photo news website Petapexel that he went to the Big Island Commons in Newcastle, New Hampshire, to catch the waves that hit the lighthouse on the whale's back (pictured above). Riesman used a tripod and a lens length of 150-600 mm to shoot by the tree. He never noticed that there were other photographers nearby. Eric Gendero, a photographer who is less than 100 feet, is also shooting the lighthouse, apparently never paying attention to Riesman.

But even if they find each other, they may not necessarily take the same photo. [2065 438+07 Best Scientific Photo]

I have done some photography work. In sports or news activities, I sometimes find myself shooting beside rows of photographers at the same time: a catcher jumps to catch the ball in the air, a politician gestures during a speech, and a couple wears wedding rings on each other's fingers. But I've never seen two photos look exactly alike.

Take a moving scene in continuous shooting mode, and you will see that the photos taken several seconds apart look very different.

Photography involves too many choices to repeat photos. On the lighthouse, the photographer can move the lens to the left or right of the photo. One may include more oceans, and the other may include more skies. Or they may not be amplified to exactly the same amount.

Even if they make the same choice, device differences will fundamentally change the appearance of the final image. As Riesman wrote for petapxel, he and Zhan Delong used different cameras to shoot. Riesman used the Canon 5D Mark IV, which has a bigger "Quan Huafu" sensor to generate images and shoot more scenes. Gendron uses Canon 60D, whose sensor is smaller and the image taken with similar lens looks bigger. Ri *** an suggested that Gendron must be far away, considering that both photographers used 600 mm lenses.

(Ron Ri *** an) still choose and share their favorite images from almost the same photos they took. When the waves hit the lighthouse, they match each other almost perfectly-this is an amazing coincidence of any dynamic and moving object, let alone something as changeable as flowing water.

Ri *** an wrote that when a local TV station shared his photo on Facebook, someone in the comments accused him of stealing Gendron's image. When he saw Gendron's photo, he suspected that his photo might have been stolen by a photographer he had never seen before.

"We got an image that looked exactly the same, taken from the same position and angle in exactly milliseconds," he wrote.

But careful observation shows that there are subtle differences in the waves in the photo, the most obvious being the upper left corner of the lighthouse. There are also slight rotational asymmetry and perspective differences on waves, which will appear when you superimpose images. (They also clearly see that their images are slightly different, because the photos of Gendron are getting brighter and brighter. )

Nevertheless, in the long shooting day, the chances of two photographers taking such similar photos and then choosing the same photos to share are immeasurable. This is an amazing coincidence.
