Introduction:
In my inaugural article for CivitAI, I explore the capabilities of SDXL ComfyUI, focusing particularly on its potential with just a few nodes to generate photorealistic output, a pursuit I've primarily pursued for sharing on Instagram.

Embarking on this journey has been immensely gratifying, as I've navigated through various models, LoRA's (Language-Optimized Rendering Algorithms), and other resources. This led me to feel compelled to share my insights through this initial article, with many more to come in the future.
While I typically design workflows for my personal use, I recognized the importance of contributing. Much of what I've learned stems from utilizing this website, watching YouTube tutorials, and of course, gaining insights from my wife. Some nodes within the workflow may appear collapsed, as they serve as connector nodes without requiring specific values.

Regarding the focus of this article, we will delve into how this particular workflow excels in producing clear and sharp images solely within ComfyUI, without the need for additional tools. (You can see what it is capable of by checking my Gallery images out!). More than 1,000 images...

A quick note:
If you utilize the default configuration of this workflow (which is configured for a single model input and no LoRAs), the processing speed is fast. However, if you begin adding LoRAs in the Positive Prompt, it will slow down. The same slowdown occurs if you use "embedding" in either the Positive or Negative Prompt. By default, it's configured to utilize a "TURBO & LIGHTNING" model. You have the option to adjust the Steps & CFG to use standard SDXL models. However, for optimal quality, it's advisable to customize the settings. Once you've fine-tuned them to your liking, simply press and hold the "Queue Prompt" button on the ComfyUI Manager to specify the number of times you want the prompt to run. Alternatively, you can configure the Batch value to obtain the same number of images.

The Ultimate 24-bit SDXL ComfyUI Workflow:
1. 20-30 seconds per image (*not including upscaling which is also quick*).
2. Image is 24-bit by default (*you can change this by changing the main multiplier value from 2 to 1*).
3. All images are in "lossless" PNG format with all "EXIF data embedded".
4. Most images are between 10-30Mb in size, this gives the best quality and clarity.
6. Dual SDXL Model Merge Ratio built-in.
7. Dual SDXL Lora Merge Ratio built-in.
8. Dual SDXL CLIP Slip control per Model.
9. Dual Lora Selectors.
10. Dual Model Selectors.
11. FreeU V2 built-in.
12. Supports all SDXL "Turbo" & "Lightning" Models, as well as standard SDXL.
13. Supports "Preview" image on "KSampler Node (Advanced)" and Upscale "Preview". This allows you to stop waiting for failed image creation if you notice a failed image render. It can be cancelled at anytime.
