Node by Node

Stop leaving your images to chance. Start designing them.

ComfyUI looks scary at first: a dark canvas, boxes and colored cables everywhere. Most people give up after one tutorial video. This book takes you through it node by node - from your very first image to a workflow you built yourself and can repeat whenever you need it.

Learn by doing, not by reading

Every chapter ends with a task, and 11 ready-to-run workflows let you skip the setup and see a result in minutes. Drag a file onto the ComfyUI window, click Run, then change one setting at a time and see exactly what it does.

Inside, you'll learn how to:

• install ComfyUI and create your first image, even on an 8 GB graphics card
• write prompts the model actually understands and master the six settings that really change the result
• start from a photo, fix one part of an image and extend it beyond its edges
• upscale for print, keep a shape with ControlNet and add a style with LoRA
• combine everything in one graph and produce a whole series with a single command
• find and fix errors in five steps and check quality before anything leaves your desk
• check model licenses and the rules in the US, UK and EU before you sell an image
• build a portfolio and an offer, so your new skill can turn into paid work

Tested, not guessed

Every workflow was run from start to finish on an ordinary PC with an 8 GB graphics card and 32 GB of RAM. The generation time is printed next to every exercise, so you always know what to expect. All workflows use built-in nodes only - no extensions to hunt for.

Companion download pack

Workflow files, exercise images, a batch script, checklists, a license register and brief and offer templates. No account and no e-mail needed - the link is inside the book.

Printed in full color

Every result and every graph appears in color, right next to the settings that created it.

You don't need to code or draw. You need a computer, a few evenings and this book open next to ComfyUI.
