🖼️ Exploring Character Reference in Leonardo AI

The script introduces a new feature in Leonardo AI called 'character reference', which is part of the image guidance tool. It allows users to select an image as a reference for generating images with consistent characters. The user interface has been revamped, and the feature can be accessed by clicking a plus sign next to the prompt box. Users can choose an image from various sources, including uploaded images, community feed, or follower feed. The script demonstrates how to use the feature by selecting an image and generating images with varying levels of adherence to the character reference, from low to high. The script also explains how to interpret the results based on the level of adherence indicated by hovering over the image guidance icon.

🎨 Customizing Image Generation with Different Presets

The script continues by exploring different image generation presets in Leonardo AI, such as 'Leonardo lightning' and 'cinematic Kino', which use different models like Kino XL for photorealistic results. The user can adjust the style, contrast, generation mode (fast or quality), and the number of images generated. The script highlights the impact of these settings on the consistency and quality of the generated images, noting that higher quality settings increase the cost in tokens. The user also experiments with different character reference levels to see how well the character is replicated in the generated images, concluding that sometimes higher quality settings do not necessarily improve character adherence.

🌟 Testing Character Consistency Across Various Styles

The script delves into testing the character reference feature with different styles and models, such as 'lifelike Vision' and 'illustrative Alto', to see how well the character consistency is maintained. The user changes the source image to a more straightforward angle to improve the results and tries generating images with different prompts, like 'portrait of a doctor'. The script also touches on the use of the Alchemy upscaler to fix minor inconsistencies in the generated images. The user generates images using various presets, including 'stock photo', 'Kino cinematic', 'portrait perfect', and 'anime', comparing the consistency and style differences across these models. The script concludes by guiding viewers on how to use the character reference feature effectively and encourages exploration of other creator tools.
