Camera Flash Communication Methods Comparison (TTL vs E-TTL i-TTL p-TTL) and Thyristor Auto Mode

ttlmethods

I talk about camera flash communication methods (TTL vs E-TTL i-TTL p-TTL) as well as thyristor sensor based auto mode. Here is the Youtube video: Diagram for TTL and pre-flash based TTL methods: Standard TTL: This was the original method of flash power control. It happens as the film/sensor is being exposed to light. There is a dedicated sensor near the film that monitors the reflected light off of the … Continue reading

Youtube video link: The camera lens aperture is the variable opening inside the lens that lets more or less light into the camera. A small aperture has a larger number. See a full technical description of aperture on Wikipedia: http://en.wikipedia.org/wiki/Aperture Also important is the f-number that explains what the aperture number means: http://en.wikipedia.org/wiki/F-number … Continue reading

I want to do a lot more learning and tutorial based videos in the future. The video on Youtube: The exposure triangle: All current cameras can manage exposure pretty well, so it isn’t bad to let your camera manage the details while you focus … Continue reading
