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