AI image generators have exploded in popularity over the past few years. They have received positive reviews from many users, but there are also concerns around their use.
These concerns are centered on copyright. If an AI is able to generate original content, it can create works that aren’t protected under US law.
Text Prompts
AI image generators understand text prompts to render the visuals you want. They include a subject, descriptors (adjectives and adverbs that describe the subject), and aesthetic or style keywords.
The most important thing to keep in mind while writing a text prompt is that it should be clear and specific with at least 3 to 7 words. It should also focus on subject and style keywords instead of connecting words.
While many AI image generators use a combination of text and image prompts, it is possible to create unique renderings using only image prompts. In fact, some of the most accurate and detailed visuals are created with only image prompts.
Stable Diffusion is a free AI art generator that uses a latent image-to-image and text-to-image diffusion model to create images within seconds. It uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts, and a UNet autoencoder to convert the input text into an image.
Image Prompts
AI image generators use text prompts to render images that meet the specific requirements you write in them. Depending on the particular AI, these can range from basic icons to illustration or artwork to photo-realistic depictions of 3D objects.
A good prompt for AI image generation should include a subject (the main focus of the visual) and additional descriptors to help the AI generate a rendering that fits your specifications. Avoid using abstract concepts as they may lead to inaccurate results, but concrete nouns are a better option.
Additionally, you can add aesthetic and style keywords that will give the AI more instructions for generating an image that matches your preferences. For example, the rendering on the left was created by using a simple prompt with a subject and some additional descriptors, while the one on the right was generated by combining aesthetic keywords with a more defined art style.
Image Styles
AI Image Generators can create a wide range of different images, from abstract art to high-quality illustrations. Some of them are simple to use and others offer more advanced features.
Nightcafe is an excellent AI image generator that creates versatile digital artwork. It uses neural style transfer to turn real-life photos into artistic masterpieces.
The site is divided into two sections: Altair and Orion, each generating different types of digital art. The first section produces images that depict abstractness, while the second produces fiction.
Dream by Wombo bucks all the limitations and restrictions found with other AI-based text to image art generators. It lets you create unlimited pictures in any style, and it is as easy to use as creating an account and entering a text prompt.
Its latent diffusion model changes a random image into a coherent one based on the prompt and style of the art. It supports a variety of art styles, including Ghibli, Dali, Love, Robots, Psychic, Synthwave, Baroque, and Dark Fantasy.
Image Formats
Whether you’re printing an image, sharing a design on the web or downloading it in a PDF, the correct file format is crucial. The wrong one can cause your graphics to appear grainy or miss details.
Fortunately, AI image generators come in many formats so you can find one that suits your needs best. The AI Image Generator Documentation gives you an overview of each of these formats and helps you determine which one is the right fit for your project.
Most of these AI image generators work by training a neural network on billions of text-to-image pairs. They then use this data to generate images that match the prompt you provide.
