The camera maintains a close, dramatic perspective as these colossal creatures launch themselves skyward from the dark blue ocean, creating enormous splashes and showering cascades of water droplets that catch the sunlight. In the background, misty, fjord-like coastlines with dense coniferous forests provide context. The focus expertly tracks the whales, capturing their surprising agility, immense power, and inherent grace. The color palette features the deep blues and greens of the ocean, the brilliant white spray, the dark grey skin of the whales, and the muted tones of the distant wild coastline, conveying the thrilling magnificence of marine megafauna."

Example prompts to try:
- A horizontally oriented rectangular stamp features the Mission District's vibrant culture, portrayed in shades of warm terracotta orange using an etching style. The scene might depict a sun-drenched street like Valencia or Mission Street, lined with a mix of Victorian buildings and newer structures.
- Painterly landscape featuring a simple, isolated wooden cabin nestled amongst tall pine trees on the shore of a calm, reflective lake.
- Filmed cinematically from the driver's seat, offering a clear profile view of the young passenger on the front seat with striking red hair.
- A pile of books seen from above. The topmost book contains a watercolor illustration of a bird. VERTEX AI is written in bold letters on the book.
