# Grain and a title
## Grain

A fine, even grain over the whole picture takes the plastic smoothness off a gradient and hides banding. It is on out
of the box at a subtle 0.035; it is one of the [effects](https://mpdreamz.github.io/undertone/pictures/effects), with a slider for its amount, or off.
The grain is about a point across on
any display.

## A title

**Show a title**, on the **Title** page of **Settings…**, writes a title and a smaller subtitle in the middle of the picture, white on dark pictures and near
black on light ones. It is off until you turn it on. These are filled in:

| Placeholder  | Becomes                                                        |
|--------------|----------------------------------------------------------------|
| `{computer}` | The computer's name, as in System Settings › General › Sharing |
| `{user}`     | Your full name                                                 |
| `{os}`       | The macOS version, for example `26.6`                          |
| `{host}`     | The network host name                                          |

The defaults are `{computer}` and `{user} · macOS {os}`. Handy for telling machines apart in screen shares.
