A Beginner's Guide to AI Image Generation with Prompts

How do prompts function?

LLM model breaks down the words and phrases in a prompt into smaller parts called tokens. These tokens are compared to its training data and then used to generate an image.

Manual Prompt

Following the basic rules for manual prompts listed below will help you generate faster and more accurate renderings.

1. Avoid requests and instructions

   Instead of saying, “Render a red sofa for me,” simply describe the object as “a red sofa.” The reason for this is explained above: prompts are broken down into tokens of adjectives and nouns, so requests or instructions don't mean anything to the model and do not affect the output image. Key adjectives or nouns like "red" and "sofa" are used as tokens and will appear in the result.

2. Prompting is a step-by-step process

   You should treat prompt building as a step-by-step process. Each time you refine your prompt, you'll learn more about how prompting works and its limits. Once you grasp how wording affects the outcome, you'll be able to create precise images with very little prompts.

   Start with something simple and refine your prompt step by step. You might come up with new ideas during the process.

   

   1st prompt : Red brick wall

   

   2nd prompt: Red brick wall, black garage door, grass front yard

3. Avoid Ambiguity: Be Descriptive and Specific

   If you know exactly what you're looking for and want a very detailed picture, you should be as descriptive and specific as possible. Instead of saying "A pretty front yard," use: "A lush green front yard with blooming flowers and a tall leafy tree."

4. Define the Context Clearly by using keywords

   A picture should include the subject, background, and other key elements. To get the best results, include multiple elements and provide clear context. You can emphasize style, mood, and aesthetics to change the overall feel of an image.

   Here is an example:

   

   Keywords: luxury / dark theme / modern / studio shot

   Here is a list of details you might consider when writing a prompt:

Autoprompt

The auto-prompt feature is a great user-friendly feature ReRender provide to enhance your prompt. The Auto-prompt function will combine your input text with the auto-generated prompt of your input photo.

By using Auto-prompt, you can see how the model turns your input image into text. Remember, prompting is a step-by-step process, and you can adjust the prompt to fit your needs. Over time, you'll learn to write clear and precise prompts.

Here is an example of the Autoprompt feature and its result:

How to prompt with or without preset styles

1. Custom Style

   Use Custom Style if you have a strong understanding of styles and prompts. It gives you maximum control over your image generation. You should follow the basic rules mentioned above: be specific and descriptive, clearly define what you want, and refine your prompt step by step. Over time, you will achieve the best results.

   Here is an example:

   

   Prompt: The photo captures a breathtaking view of an architectural masterpiece inspired by the Wonnam Temple. Set against a backdrop of a soft, cloudy sky, the two-story neighborhood facility stands as a modern oasis within an urban environment, revealing itself with elegant, fluid curved forms that embody an organic flow. The sleek glass and metal materials shimmer under the muted daylight, enhancing the building's transparency and inviting reflections of the soft clouds above. In the forefront, the building’s façade boasts large, seamlessly integrated glass panels that stretch from the ground floor to the second, offering glimpses into the serene, light-filled religious assembly hall housed on the upper level. The hall is flooded with natural light, creating a warm atmosphere that seems to merge with the surrounding greenery.

2. Prompt with Preset Styles

   If you have limited knowledge of styles or want to use Preset Styles. You can skip describing the overall style. Choose one and simply describe the key elements and changes you want to make. You can also generate an image without using any prompt. Usually, the color, texture, and overall aesthetics are already set.

   Here is an example:

   

   

   Prompts: No prompts

   Style: Neo Futurism
