This ComfyUI tutorial workflow upscales a landscape photo and restores fine natural detail using the TopazImageEnhanceV2 node. It starts with LoadImage, reads the original dimensions via GetImageSize, and scales the image with ImageScaleBy to your chosen factor (for example, 2x or 4x). The upscaled image is then passed to TopazImageEnhanceV2 (Topaz model) to bring back foliage texture, rock edges, and sky gradients while controlling noise and softness. Finally, SaveImage writes the enhanced output, and ImageCompare helps you visually inspect before/after results side-by-side.
Technically, the pipeline separates geometric upscaling from semantic enhancement. ImageScaleBy handles precise resizing based on the dimensions reported by GetImageSize, while TopazImageEnhanceV2 applies learned restoration tuned for natural scenery. The "Upscale Setting" group exposes the key controls so you can quickly adjust scale and enhancement behavior for different landscape inputs. This makes it a practical go-to for turning good scenic shots into print-ready or high-resolution web assets without over-sharpening or plastic artifacts.
API
Use este workflow a partir do código
Todo workflow Comfy é um grafo JSON. O payload abaixo é este workflow, exatamente como o ComfyUI executa — obtenha-o pela URL, mantenha-o no controle de versão ou carregue-o no ComfyUI e execute nó por nó.
Execute a partir de TypeScript ou Python com o Comfy SDK. O mesmo código serve para o Comfy Cloud ou um ComfyUI hospedado por você — apenas a URL base muda.
// Install (beta)
npm i @comfyorg/sdk
// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");O SDK utiliza um workflow no formato API: abra este workflow no ComfyUI e use Arquivo → Exportar Workflow (API).
O acesso à API do Comfy Cloud requer um plano com chave de API.
