The ability to use generative artificial intelligence (AI) to create images from a simple text input has taken the world by storm. Tech companies are eager to keep tweaking the user experience, as Adobe's latest feature update shows. 

At Adobe Summit on Tuesday, the company unveiled Structure Reference capabilities in Adobe Firefly, its text-to-image generator. This feature gives users even more control over the output of generated images.

Structure Reference lets users input an image they want the AI model to use as a template. The model then uses this structure to create a new image with the same layout and composition.

For example, during Adobe's live event demo, a user inputted an image of a person's profile as a structure reference. Then, Firefly outputted several new pictures that kept the "structure" of the original profile photo, as seen below:

You can tweak the "strength" of the structure reference, or how much the model adheres to the reference's image structure when creating a new image. For example, if you want Firefly to use an input image as a loose guideline, you can move the stub to the lower end of the strength spectrum. If you want the image to adhere to the reference exactly, you can set the tool to maximum strength.

This new Firefly feature works alongside Style Reference, also seen in the demo above, which uses an image as a reference to generate a new image in the same style. This new picture uses the reference and keeps the same stylistic choices, such as feel and color scheme.

Users can now use a combination of Style Reference and Structure Reference, and detailed prompts, to ensure that the image generated matches their needs as much as possible on the first attempt.

"It's like going from 2D to 3D, to go beyond words into a more multimodal approach, that includes sketches and images," Deepa Subramaniam, Adobe's VP of product marketing, told .

Using images as guidelines means users don't have to create a prompt and tweak it several times to get the desired outcome. This feature is useful when users can't find the words to describe the image they are visualizing, but a quick sketch or reference image can. 

Adobe has added Structure Reference to Firefly on the web and on mobile. You can try the feature for free by visiting the Adobe Firefly website, where you can start tinkering with images and text prompts.
