I have been getting a private lesson 1 on 1 with instructor Kendra..

Finally I got into controlnet and open pose after procrastinating for a long time. I just thought it looked busy or a bit involved so I was sticking to what I knew and focused on other aspects of SD. In the pursuit of generating widescreen images, I learned that it was probably controlnet and it's complimentary extensions that was the answer. I first learned the method of "outpainting", meaning first generating a normal upright portrait ratio image and then with SD upscale and the "resize fill" option selected, then "outpaint" the rest with controlnet inpaint. This did the trick but was hit and miss. It was difficult to get it to blend well with the original, you always get a seem between the two. I learned from Sebastian Kamph to then do a normal img2img generation. This will blend the two together and then you can uspcale it. During my research I came across a different method however that excludes the need for any "outpainting". You will instead use the latent couple extension in txt2img. With it you can assign a part of the prompt to a specific region of the image.
If you want a normal 16:9 ratio widescreen image this division and settings (se example) has been working the best for me.

You will separate the prompt with "AND" for each region. I write all the light and image quality tags for the first region, the subject tags for the 2nd and the background and/or scenery for the 3rd.
Here's how a prompt can look like:

If you are going to use a Lora like me you also need to use the extension "Composable Lora".
You can also assign the negative prompting in the same way to each region by separating with "AND", though it's not always necessary. Use the same value for "end at this step" as your sample steps.
You can move the subject within the image by changing the position value for the 2nd region, 0:0.7 for example.
This will shift it of center in the image. Then press "visualize" to apply the new setting.

Set the resolution of the entire image in text2img, for example 960x540, write your prompt and separate the regions with "AND" , also the negative prompt in the same way if needed.
Select your sampler and steps and cfg etc like normal, Setup the Latent couple extension settings and Composable Lora then generate.
To take it even further you can also use open pose to control the pose of the subject and to bump up the quality you can either use hiresfix with the primary generation or SD upscale script in img2img.
