Now we're rolling
. Hey dirtech, that's pretty good for your first beamshot.
That looks like a pretty typical Cree XP-G beam...... medium sized hotspot with a medium sized spill.
White wall beamshots are great for showing the beam profile, especially if you show it next to another light that most folks already know, that way we have something to compare it to.
The main thing is to establish some kind of consistency. The same distance from the wall, the same settings on the camera, etc.
What I normally do is keep the camera in full manual mode and take notes of the camera settings. I'll lock the white balance on "Daylight", and note the ASA setting, the F stop, and the shutter speed, along with the distance from the wall, and then include that info with the photo...... along with the light information. For instance, was this shot with the light at full power?
Some folks will also include a few more shots. For instance, with 1 and 2 stops under that first shot (faster shutter speed or smaller F stop), and 1 and 2 stops over that first shot (slower shutter speed or more wide open F stop). These let us see various aspects of the beam.
Then do the exact same setup with any other lights you have. That way we can see how the beam on the Logan compares to other lights. Same distance from the wall, same ASA, same shutter speed, same F stop, and with the white balance locked to "Daylight".
The other thing would be to do a real life setup type shot with all your lights. Some folks use a long hallway, some folks go outside and use a forest, some use their living room. The idea is to be able to see how the light pattern looks in the real world..... the combination of throw and spill...... so you need stuff at various distances (both away from the light and to the sides) to act as markers...... like an alley way...... or a field with trees...... etc.
In this case, you're trying to get the photos to give a realistic representation of what you are seeing, but at the same time keeping the camera settings the same from light to light.
In any case....... great job, and thanks for contributing.
