# whose eye do you have?

a vision test for image compression, in the spirit of [ismy.blue](https://ismy.blue). each call shows the same photo squeezed two or three ways, and you **pick the one that looks best.** we won't say what changed, on purpose: if we told you to watch the color, you'd watch the color. so answer on instinct.
