It’s Wednesday, and the ⏱️ countdown for Winter break is on, Vampires! 

In today’s edition, we want to expand on the topic of image generation with AI. 🖼️

While most of us have used ChatGPT to plan lessons, write emails and generate ideas, the upcoming holidays could be as good a time as ever to learn more about how to generate your own AI art. 

Let’s also consider the possibilities and implications in our classrooms.

Understanding AI Image Generation

AI Image Generation uses complex algorithms, often referred to as neural networks, to create images from textual descriptions. These tools have been trained on vast datasets, enabling them to generate detailed and diverse visuals. 

This video explaining AI in art and image creation is on the longer side (13+ minutes), but it is a good introduction to how these tools came to be.

How-To guide

Getting started with AI image generation is straightforward.

Choose a platform like DALL-E, and create an account. When you input a descriptive text prompt, the AI generates an image based on that description.

BUT... most of these tools have a cost attached. For example, to use DALL-E 3 without limitations, you need credits, or a ChatGPT Plus subscription.

The two most popular image generation tools are DALL-E and Midjourney.

 To use them, read the steps below:

DALL-E 3:

Sign Up for an Account. You’ll need to provide some basic information like your email address.

Free credits: OpenAI typically offers a set of free credits that you can use to generate images with DALL-E 3. 

💰However, without a premium subscription, your use of DALL-E 3 will be limited by the number of free credits you have. Once these credits are used up, you’ll need to wait until the next month for additional free credits or consider upgrading to a premium plan for more extensive usage.

Midjourney:

Join the Midjourney Community: The primary way to access Midjourney is via its Discord server. You need to join the Midjourney Discord community, which you can find through the Midjourney website or by searching for an invite link online.

Create a Discord Account: If you don’t already have a Discord account, you’ll need to create one. Discord is a communication platform that supports text, voice, and video communication.

Navigate to the Midjourney Bot Channels: Once you’ve joined the Midjourney Discord server, look for channels that are designated for using the Midjourney bot. These are usually named something like #newbies-1, #newbies-2, etc.

Enter Your Image Prompt: To generate an image, you type a command in the chat followed by your image prompt. The standard format is /imagine prompt: [your prompt here]. Replace [your prompt here] with a detailed description of the image you want to create.

Refine Your Image: Midjourney often provides a few variations of the image based on your prompt. You can choose to upscale (increase the resolution and detail) of any of these variations for a clearer image, or you can modify your prompt and try again for different results.

💰Limited Free Trials: Midjourney offers a limited number of free trials for new users. After these trials, you would need to subscribe to continue using the service.

✨ But you can still use Bing to access GPT4 and DALL-E 3 for free!

Go to bing.com/create and simply type your prompt.

Ethical considerations and Digital Citizenship

While AI image generation is a powerful tool, it’s crucial to discuss its responsible use.

➡️ To begin with, remember the age restrictions…students themselves can only use these tools if they are 13+.

Regardless of the tools they use to find images for projects, it is essential to educate students about the importance of copyright laws, especially when recreating artworks or using generated images in public projects.

Discussing AI biases is just as important.

🔗 AISB’s Responsible Use Policy states:

I understand that the use of artificial intelligence tools poses ethical questions. Artificial Intelligence tools can only be used when directed by teachers.”

Sizes and technical aspects

Here are some key aspects to consider:

1. Resolution and Dimensions: AI-generated images often have default resolutions set by the platform (e.g., 1024×1024 pixels for DALL-E). Some platforms allow custom resolutions, but they might be limited to premium plans. 💰

2. Aspect Ratios: Many AI image generators support standard aspect ratios like square (1:1), widescreen (16:9), and portrait (9:16).

3. File Formats: AI-generated images are typically available in common formats like JPEG or PNG.
