画像プロンプトジェネレーター FAQ
画像プロンプトの使い方、利用先、image-to-prompt ツールとの違い。
What is an image prompt generator?
An image prompt generator turns a rough visual idea into a clearer instruction for AI image models. It helps define the subject, setting, style, lighting, camera, composition, aspect ratio, and constraints.
Is this different from image to prompt?
Yes. An image prompt generator starts from your written idea and creates a prompt. Image to prompt starts from an existing image and describes it as a reusable prompt.
Can I use these prompts in Midjourney, DALL-E, Flux, or Stable Diffusion?
Yes. The generated prompt uses clear visual language that works across common image models, and the target model selector adds wording that better matches each workflow.
What should I include in a good AI image prompt?
Include the subject, scene, style, lighting, composition, camera angle, mood, aspect ratio, and anything to avoid. Product and brand visuals should also include material, background, and use case.
Do I need a negative prompt?
Negative prompts are most useful in Stable Diffusion-style workflows, but they can also help you think through what the image should avoid, such as blur, artifacts, messy backgrounds, or unreadable text.
