## Image settings in CVAT
|
||
|
|
|
||
|
|
The **Image settings** panel serves
|
||
|
|
as a versatile tool for fine-tuning the visual aspects of your image.
|
||
|
|
Whether you need to brighten the image,
|
||
|
|
increase contrast, or make other adjustments, this panel is your go-to.
|
||
|
|
|
||
|
|
Additionally, the panel allows you
|
||
|
|
to overlay a grid on the image for more precise annotation.
|
||
|
|
|
||
|
|
{{% alert title="Note" color="primary" %}}
|
||
|
|
Adjusting the image settings only
|
||
|
|
alters how the pictures are displayed.
|
||
|
|
The images themselves will remain unmodified and unchanged.
|
||
|
|
{{% /alert %}}
|
||
|
