# Enlarge an image with Duaer Upscale

In Duaer, Duaer Upscale enlarges an existing image and keeps the subject, layout, colors, and text.
## Enlarge one image

1. Connect the node that holds the image to Duaer Upscale. It reads binary field data by default.
2. Open Model and pick an image model. The charge is one image at the price of that image model.
3. Select Execute step. A wide image asks for 2560×1440, a tall image for 1440×2560, and a square image for 2048×2048.
4. The result is in the output binary field, named duaer-upscale-1, with model and size.

## Questions

### Why does Duaer Upscale fail before any request?

The input field is empty, it is not an image, or the node has no Duaer access. Fix the field and run again. That attempt is not charged.
