you have to save it, then zoom in and out on it
just some totally random photo i took and was about to delete of my phone when i noticed something
you can see curvature lines on the the photo when it is zoomed out ie made smaller
especially on the top left corner, these lines actually change shape and disappear
i was certain i could zoom in and still see some evidence of the curvature lines
it seems to me like the light refraction effect still works even from the photo
i could be wrong though
sorry about it not being bitcoin photo though its good to have something off topic and to stretch the
mind from time to time and this forum has the most brightest users out of any IMO
