Pro Tips for Better Results

For Portraits

Include specific details: "portrait of a woman with freckles, auburn hair, green eyes, wearing a yellow scarf, golden hour lighting, shallow depth of field, 85mm lens"

Text in Images

Keep text short and place it in quotes. "A neon sign reading 'OPEN' on a brick wall" works better than long sentences.
