TTL flash
With TTL flash photography, the reflection of the flash is metered and the
intensity of the flash is adjusted automatically, which can mean TTL flash
photography may not be suitable for all shooting conditions. In the cases
described below, we recommend that you use a flash meter to check the
intensity of the flash or use a manual flash setting.
Example:
1. When the size of the subject you want to light with the flash is
relatively small within the picture
2. When the background behind the subject is extremely bright or when
there is a strongly reflective object in the background
3. When the background behind the subject is extremely dark (outdoors
at night, etc.)
4. For flash photography with a narrow sensitivity latitude
