Photorealistic images from Imagen 3

Science & Technology

Introduction

In the fast-moving world of generative AI, the realm of image generation is reaching new heights with the launch of Imagen 3 on Vertex AI. This newest model offers the highest quality in text-to-image generation. In this article, we will explore how to design prompts that showcase the innovative features of this model.

Overview of Imagen 3

Image generation models work by taking in a text description, also known as a prompt, and outputting a newly created image based on that description. With Imagen 3, one of the standout features is its ability to produce photorealistic images with fewer distracting visual artifacts.

Example 1: Photorealistic Image Generation

Let’s navigate to Vertex AI Studio to see this in action. Suppose we want to generate a photorealistic image of a family on an RV camping trip. Our prompt could be:

"A professional photograph of a happy family of four people sitting around a campfire outside of an RV, making s’mores and admiring fireflies above their heads."

As a result, we can observe that all elements of the prompt, including the number of people and their emotions, are accurately depicted in the generated image, showcasing the realistic quality of the output.

Example 2: Text within Generated Images

Another remarkable feature of Imagen 3 is its ability to effectively render text within images. For example, if we want to create images for an advertising campaign for a new flavor of strawberry sparkling water, we could use the following prompt:

"A minimalistic can of strawberry sparkling water with only the Sparkle Water logo and 'Your Summer Flavor' in red and yellow font, set against a summer fun background."

The generated image displays the exact text and color as specified, demonstrating the model's capability in rendering textual elements seamlessly within visual contexts.

Model Varieties: Imagen 3 and Imagen 3 Fast

Imagen 3 comes in two varieties: Imagen 3 and Imagen 3 Fast. The faster version optimizes for latency and cost. To illustrate the differences, let's generate images with both models using the prompt:

"A red sports car sitting on a cliff, blurred background to focus on the car, in a landscape orientation."

By comparing the outputs from both models, we can see that while Imagen 3 Fast reduces latency and costs, the detailed rendering in the standard Imagen 3 model provides superior quality. Depending on your use case, experimenting with these model outputs will help you find the best version for your needs.

Conclusion

This brief overview has highlighted some of the advancements offered by Imagen 3, all of which have been illustrated using Vertex AI Studio. Importantly, you can also integrate Imagen directly into your applications through an API. The possibilities with this model are truly exciting, and we look forward to supporting your creative processes.
