💡Leonardo AI

Leonardo AI is an advanced image generation tool that utilizes artificial intelligence to create images based on user-provided prompts. It is the central focus of the video, as the speaker guides viewers on how to use its features to generate high-quality images.

💡Negative Prompts

Negative prompts are a feature within Leonardo AI that allows users to specify elements they do not want to appear in the generated images. This is crucial for refining the image generation process, ensuring that the final images meet the user's expectations by avoiding unwanted features.

💡AI Image Generation

AI Image Generation refers to the process of creating images using artificial intelligence. In the context of the video, Leonardo AI employs this technology to generate images based on textual descriptions provided by the user, making it a key component of the tutorial.

💡Cinematic Photography Style

Cinematic photography style is a visual aesthetic often used in movies that aims to capture images with a dramatic and engaging quality. In the video, the user specifies this style when generating an image, indicating a preference for a more artistic and visually impactful result.

💡Full Body Shot

A full body shot is a type of image that captures a subject from head to toe. The video script mentions this as a desired outcome for the image generation, emphasizing the user's intention to create a comprehensive representation of the subject.

💡Distorted Hands

Distorted hands refer to an undesirable outcome in image generation where the hands of a subject appear unnatural or misshapen. The video instructs Leonardo AI to avoid this by including it in the negative prompts, highlighting the importance of accuracy in the depiction of the subject's anatomy.

💡Muted Face

A muted face in the context of image generation implies a facial expression or feature that lacks clarity or detail. The script mentions avoiding a muted face as part of the negative prompts, indicating the user's desire for a clear and well-defined facial representation in the generated images.

💡Low Quality Images

Low quality images are the antithesis of what users aim for when using Leonardo AI. By including 'low quality images' in the negative prompts, the user instructs the AI to prioritize image resolution and detail, ensuring the final output meets a high standard of visual fidelity.

💡Photo Real Feature

The photo real feature is an option within Leonardo AI that enhances the realism of the generated images. It requires more computational resources, as indicated by the mention of 'tokens' in the script, but results in a more lifelike and detailed final image.


In the context of AI image generation, tokens represent the computational units or resources required to generate an image. The script mentions that using the photo real feature will take more tokens, indicating that it is a more complex and resource-intensive process.
