Here are the images from the live stream David Bicho and I did on Profoto’s Facebook page. We do this live stream every Wednesday at 17:00 Central European Time.

This episode was the fourth one and is also available on Youtube (https://youtu.be/cbOggnGNnSg).

We went thru the different modifiers for Profoto A1 and their impact. Since you can zoom the A1 we have images for both zoomed in and out. The power loss is not really a power loss since it is all about how the light is spread out and I was only measuring one small spot in the middle. It is always the same amount of power and light but spread out in different ways. The flash was 2 meters from the wall and it was shot with a 24mm lens to include the whole light pattern.

This image is the A1 with no modifier at all and in the most zoomed in position.
