"Create an ultra-realistic close-up image of a frosted window. The glass should be covered in intricate ice patterns, with delicate, natural frost formations resembling snowflakes and crystalline structures. The texture of the frost should be highly detailed, with varying opacity to show the subtle differences in thickness across the window. Ensure the glass itself is slightly blurred or translucent, giving a sense of the cold environment outside. Use advanced rendering techniques to capture the play of light on the frost, with soft, diffused lighting and shadows that enhance the realism. Maximize resolution and quality settings for an exceptionally sharp, lifelike image.
