Well, I have re-joined the living. I wasn't convinced that I was going to for a while, but I'm back. I had my pacemaker replaced on Monday and I was back home on Tuesday, but it was a pretty rough surgery and I'm still in considerable pain. A Technicolor movie has nothing on the shades of color showing on my right side from the under the skin bleeding that occurred, but in time I won't be as spectacularly colored as I am now. Still in considerable pain, but I'm doing better that way too. I'll spare you all from viewing the photos that have been taken.
So, on to my first reply to the posts on this forum since my new pacemaker has been installed -
Other than the LED panels not being very bright, the 8 that I have, the GVM 480 LS provide great even light with the wide leg U pattern that I have them placed in on my studio ceiling. They are above three sides of the banquet table that we have used in these videos, and angled down at about 40 degrees. There are two LED Panels on each of the sides, and four across the base of the wide U pattern. Each is spaced 2-3 feet apart and angled to point roughly at the banquet table. They are attached to a ceiling lighting support grid, a DIY project of 1 X 1 X 1/4" steel angles that are about 10' long and spaced 4-5 feet apart running parallel with my backdrop system. These are about 4" below my studio 8' ceiling. If I want to hang a light or something else that's between two of these angles, I have 5' long pieces of this same angle material that I can bridge between any two of the 10' long angles to allow hanging a light or other anywhere within the shooting area of my studio. For these LED panels, the 10' long angle with the 4 LED panels is the 4th 10' long angle when counting back from the backdrop end of the studio. This is roughly above where the camera is located. For the side legs of the U pattern I have added two 5' long angles to each side (I don't have loose 10' angles, and they would be hard to position, so just use two of the 5' angles on each side of the shooting area). At present, two LED panels are placed on these along each side of my shooting area, and also angled down at about 40 degrees.
I installed surface mounted power strips on the studio ceiling, running from the backdrops to near each end of the last of the 10' long angles, so Mains power receptacles are available every 6" along each of these, and power is available within 5' of anywhere that I choose to hang a light. Since most lighting on light stands is placed along both sides of the shooting area, this power strip arrangement provides power for any light on a light stand below as well. So no power cables, and a minimum of tripod light stands are ever on my studio floor, making the studio a much safer place for me and my subjects. A common electrician piece of hardware called an "Electricians Beam Clamp" provides the attachment point for lights and even in pairs are used to attach the crossing point of a 5' long steel angle to the 10' long angles. These beam clamps are a kind-of C-clamp, with a large bolt included that closes the opening to clamp it to a steel beam. The other two sides of this beam clamp are drilled and tapped for 1/4-20 threads or 3/8-16 threads, and common threads used in photography attachment hardware. To attach one steel angle to another, I use two of these beam clamps with a 1/4-20 X 1/2" round head bolt to connect the two clamps together. Then one of the clamps can secure to the 10' long angle and the other beam clamp of the pair can secure the 5' long angle to it. I always place the 5' long steel angles above the 10' long angles, so if any clamp should fail, the 5' long steel angle cannot fall to the floor. It will fall against the 10' steel angle instead. Since I don't trust the spigot attachment of light to the hanging point, I also have small chain loops that keep lights from falling should this spigot connection fail. This grid attachment point is another beam clamp with a photography spigot attached to one of the 1/4-20 threaded holes in it.
So all of the lights hung from the ceiling for video, which makes moving the camera around the studio floor safer and easier. The lighting arrangement lets me light about 1/2 of my 19 X 26' studio at the backdrop end, so the area being staged is about 10 X 12' with the backdrop along the 10' side and the camera working space along the other 10' side. The videos that have been made so far consist of an 8' banquet table, two chairs and health food products on the table, with 1-2 adults sitting or standing around this table to demonstrate and talk about the products being displayed. The longest video took most of 3 days to shoot and it is only 14 minutes long. With the LED panel lights positioned this way on the ceiling, I was able to create a relatively shadow free and evenly lit area around this table that looks much like the TV News room environment that you see when watching one of the big channel News reports on your TV. I tried several arrangements of the light panels and added some, before I managed to get this stage space lit to our satisfaction, and if we make any more of these videos, Shadows in this kind of video are not what is needed. They can improve portraits, but not infomercial videos. I'll be adding two more of these GVM 480 LS panels to extend the lighted area back toward the backdrops a bit further, if we end up making any more of the videos. Near the backdrops is a bit lower in light level than desired with the present setup. It has been adequate for the videos that we made, but I haven't been fully satisfied with it, and I'm always looking to make my shoots better. These videos are on "indefinite hold" right now, and I'm beginning to doubt that any more will be made, and this is why I haven't bought the two additional LED panels yet.
