# ワイドダイナミックレンジ
高コントラストの照明条件でカメラの画像を最適化するためにWDRを有効にします
ワイドダイナミックレンジ（WDR）は、コントラストの高い照明条件で画質を改善します。暗い部分を明るくし、明るい部分を暗くすることで画質を向上させます。その結果、明るい環境でも暗い環境でも細部を捉えた、よりバランスの取れた画像になります。
***
## WDR設定を編集
{% stepper %}
{% step %}
**Verkada Command で、\[All Products] > \[Cameras] に移動します。**
{% endstep %}
{% step %}
**設定するカメラを選択します。**
{% endstep %}
{% step %}
**カメラフィードの左下で、動画品質メニューを選択します。**
{% endstep %}
{% step %}
**WDRを選択し、次のいずれかのオプションを選びます。**
a. ON\
b. DAY ONLY\
c. OFF
{% endstep %}
{% endstepper %}
{% hint style="info" %}
夜間モードで画質が低下する場合は、DAY ONLYを選択します。WDRは明部と暗部のコントラストを強調するため、夜間モードの画像がより暗く見えることがあります。
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://help.verkada.com/verkada-cameras/ja/she-ding/view-and-edit-camera-settings/wide-dynamic-range.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
