Understanding additional imaging parameters, part 1 - Midjourney Tutorial

- [Instructor] In this movie, we're going to get more familiar with parameters and how they work in conjunction with our text prompts. We're already a bit familiar with parameters as we added dash dash ar to the end of some of our text prompts, which allowed us to define the width and height of what we would like out of a photo. But these parameters can go that much deeper. Let's start off with a simple text prompt and then duplicate that text prompt with a parameter in mind. So I'm going to just type in here, imagine prompt a 1970s disco party at a nightclub. I'll follow this with a comma and the parameter that we're already familiar with, which is dash dash ar 69, and let's see what we get. Okay, so here are the four images that were generated using version V6. I can see that some of these are pretty good in terms of a disco party, but I don't like the empty room. I also don't like the colors blue and purple. So I'm going to take this existing prompt that I entered, and the aspect ratio, copy it by pressing Command + C or Control + C. Let's run the imagine prompt again, followed by colon, paste this prompt, Control + V, Command + V, and make sure you just have one colon. And after ar, let's add dash dash no to define what we don't want to see. So no, I don't want the room to be empty, so no empty. I don't want to see the color purple. I don't want to see the color blue. I'll press Return and let's see what we get. Okay, this is great. So we definitely have a disco party at a nightclub. The club is full and it is excluding both blue and purple colors from it. This is exactly what I was going for. Now let's take a look at another parameter, and for this, we're going to find out information about this job that was just created. That's these four images. I'm going to go over here to the side where it says more, the three dot icon. Click on it and select this envelope. For any reason that you don't see this, you can go under Add Reaction here and view more to find the envelope. Once you select the envelope, it'll be added to the bottom here, and we'll find out the job ID for the four images and the seed value. This seed value can be very helpful and added as a parameter to the end of your text prompt. If you don't add a seed value, Midjourney automatically creates one for you. So I'm just going to first of all, just copy the text prompt, which is still saved to memory, right? That disco party at night by pressing Control + V, Command + V. And I'm just going to add here to the front of this, a black and white photo of a 1970s disco party at a club at night. And just at the end of this prompt, again, I'm going to type in dash dash no empty blue purple, and add yet another parameter, which is dash dash seed. And for this, I want to use the same seed that was used on this job. I'll add a space next to after seed and then press Return after that number is copied. This is very interesting. So in one case, the first image that was created is very similar to the one from the previous generation. We can see that all photos are black and white. And because it used that same seed value, it does have a similar look and feel to the images produced here. Last but not least, we're going to take a look at the chaos parameter, and I might as well just run the prompt that we've been working with, a 1970s disco party at a nightclub. Okay, so I'll type in the imagine prompt and I'll copy the 1970s disco party at a nightclub. And let's add the parameter aspect ratio dash dash ar 16:9, dash dash no so empty, I'll accept color in this particular case. And last but not least, dash dash c for chaos. The chaos parameter influences how varied the initial image grids are. The highest chaos value is 100, and this is going to produce extremely unusual and unexpected results from your text prompt. While lower chaos values are going to be a little bit more reliable and repeatable results. Keep in mind, still giving you minor unexpected results from your initial prompt. Let's see how this is going to vary the initial image grid. So let's set it to 90 and let's press Return. And wow, with this high chaos value, look at the differences, number one, between each of these photos, and in some cases, how it isn't even really taking our text prompt that much into consideration. In some ways, you can consider chaos to be how much to play or deviate from your actual text prompt. Now, since this is so extreme, I'm just going to copy this entire prompt again up to the chaos value. So Command + C or Control + V, let's enter the imagine prompt, paste our text prompt and those parameters, but bring down the chaos value to 10. So maybe we can see a little bit of a reflection of our 1970s disco party. Okay, with the chaos value not set so high, we definitely do see the reflection of disco parties in this case, but you can see that it's having some fun here, the chaos party, we have a beach sort of disco party outside with lights, not even a disco ball. Then one party with a lot of disco balls and another one that's inside that is more photorealistic than the others. So use that chaos value in order to instill a little bit of a randomness and surprise from your initial text prompt. So there we have it, a few parameters that we've covered. We've covered the no parameter to define what we don't want to see in our images. We then took a look at the seed value that is generated when we create our images and how we can ping our existing job to use that seed value. And last but not least, we took a look at chaos. In the next video, we'll be covering some more parameters that you can use in your image creation with Mid.
