I have been playing photography for many years. I have a question.
When I use the external flash with my cameras. Even I use TTL mode or Manual mode, the ISO, shuttler, and Aperture will have changed. Why? How to calculate by the cameras??
For example, when switch off the external flash? the the setting is 60/1, F3.5, ISO500
However, when switch on the external flash. the setting will be change to ISO100 even I use TTL and M Mode. Why?
