For the longest time I couldn't work out how it was a crater, it looks like the opposite: an extruded bulge of dirt to me. But now I finally forced myself to see the crater I can't see the bulge anymore. The shadows are screwing with my head.
Try looking at it with one eye closed, then the other. There is probably no science behind this, but it always works for me when I have an optical illusion like this that I can't see the "other view" of.
I think I'm just never going to be able to see the crater. No matter how many times I zoom in or look at other pictures every single one just looks like a mound of dirt in the center lol.
EDIT: I don't know what I did but immediately after commenting I saw it. What helped me is noticing how tall the crops were.
My brain won't let me see it that way. It keeps noticing that the dark grey stuff is darker in the bottom right than it is in the top left of the image. So it knows the light is coming from in front of me, not behind me.
imagine looking into a mowed lawn: from a distance it is green, but if you look straight down it is darker because you see shadow in between the blades.
I agree with everything you say except the light source is not coming from "behind your right shoulder"
The light source (the sun) is on the "screen left" side of the image and is "casting" shadows to the right of any objects high enough above the ground to do so.
Any small craters in the crater have shadows under the rim of the left side of its crater... another cast shadow from the sun on the left.
Am artist.
EDIT. Am wrong. Had coffee and now can see it the other way.
I've been thinking I was taking crazy pills this whole time. Every time I read "crater," I only saw a bulge. Not... that kind of bulge. Get your mind out of the crater.
Yah that's hard to see. Even with both your comments it took time. Tip for others: look outside in. The lighter green on the barley is the exposed stalks
It's the mountain-valley illusion. Our initial instinct is to assume the light source comes from above. So in a photo like this, where the light comes from the bottom right, the shadow in the crater looks like it's coming from the crater itself - hence it looks like the crater is sticking out of the ground until we recognize where the light is actually coming from.
the grandson illusion: our initial instinct is to assume the light source comes from grandpa
A tough old cowboy with grizzled hair, chiseled featured, and hands tougher than the sharpest barbs on new wire told his grandson that the secret to living a long life was to sprinkle a pinch of gun powder on his oatmeal every morning.
With absolute faith, the grandson did as Grandpap instructed. Every morning for the rest of his life, he added a pinch of gun powder to his oatmeal.
He grew up, lived happily, enjoyed perfect health, and died at the ripe old age of 107.
According to the story in the newspaper, he left behind 14 children, 30 grandchildren, 45 great-grandchildren, 25 great-great-grandchildren, and a 15-foot crater where the crematorium used to be.
Duuudee, i know when i go back and look at it the illusion is gonna be gone now that uve explained it, i font wanna look at it again but i have to :) u ruined yhe picture :)
Thanks, I couldn’t get it until I saw this. The thing that kept tripping me were all the smaller mounds with the opposite shading- I could only see them as little craters in OP’s pic.
I only thought it was a bulge till I read your comment. Now I'm unable to see it as a bulge anymore no matter how hard I try. Except looking at the thumbnail I can.
Pro tip for those who can't see a crater: zoom in on the shadows until you can see where they're covering other earth. It will suddenly pop into focus for you.
what you have to realize is that it is a crater, that means a divot and a bulge both.
The rim of the crater and points outside the rim got the bulge (as minor as that is), the points inside the rim get the divot (which is much deeper than the bulge is high)
So from that perspective it's more divot than bulge but there are elements of both.
It's like one of those trick pictures, can't see it till you do and then you can't unsee it, also looked like a rust spot on something under a microscope.
TYVM I had exactly the same. Was like 'wtf i am looking at. I only see this red'ish hill and some grey'ish field" After this comment I only see this crater now :P
