Style and Artistic Medium Specification

Photorealistic, oil painting, watercolor, 3D render — style vocabulary.

Why Style Vocabulary Matters

Image models are trained on billions of captioned images. They 'know' the visual language of specific styles, movements, and artists. Using precise style vocabulary is like speaking the model's native language — it activates learned visual patterns directly rather than relying on vague description.

Photorealistic Style

Photorealistic prompts instruct the model to produce images indistinguishable from real photographs. Key vocabulary terms and how to apply them:

photorealistic_prompts = [
    # Basic photorealism
    'photorealistic portrait of a woman, DSLR photograph, '
    'f/1.8 aperture, 85mm lens, bokeh background, natural light',

    # Hyperrealism (even more detailed than photo)
    'hyperrealistic painting of a weathered old door, '
    'every crack and grain of wood visible, photorealistic quality',

    # Studio photography
    'product photography, white background, studio lighting, '
    'sharp focus, commercial quality, shot on Canon EOS R5',

    # Environmental photography
    'documentary photograph, photojournalism style, '
    'natural unposed lighting, 35mm film grain, raw authentic moment',
]

for prompt in photorealistic_prompts[:2]:

# Key terms for photorealism
photo_keywords = [
    'DSLR', 'shot on [camera model]', 'f/[aperture]', '[mm] lens',
