{{% note %}}
To improve performance and decrease cache size, if you set neither `excludeFields` nor `includeFields`, Hugo excludes the following tags: `ColorSpace`, `Contrast`, `Exif`, `Exposure[M|P|B]`, `Flash`, `GPS`, `JPEG`, `Metering`, `Resolution`, `Saturation`, `Sensing`, `Sharp`, and `WhiteBalance`.

To control tag availability, change the `excludeFields` or `includeFields` settings as described above.
