Натюрморт с яблоками на столе вид сверху

A photorealistic top-down flat-lay scene on a pale gray wood-grain desk. Exactly [7] glossy red apples are neatly arranged in two rows: exactly 4 apples in the upper row and exactly 3 apples in the lower row, evenly spaced, with realistic stems, subtle yellow-red striping, and soft cast shadows, with no extra apples. In the upper-left corner, a single blue hardcover book is partially visible, angled slightly with its spine facing inward, featuring the white text "[算法导论]" printed cleanly on the spine. Horizontally centered between the two rows of apples rests exactly one black fountain pen with elegant gold trim, its metal nib pointing to the right. In the lower-right corner sits exactly one transparent cylindrical glass half-filled with clear water, displaying realistic optical refraction, delicate rim highlights, and a soft shadow. Clean natural studio overhead lighting, crisp focus across the flat plane, balanced negative space, realistic proportions, and strict object placement. No extra objects, hands, plates, labels, or decorations.
