+My Photo account - I'm glad the video helped. I try to make my videos so they get straight to the point.

Came here to say pretty much the same thing. Hate how most videos you gotta skip the first twenty+ seconds because everyone needs some stupid intro video. These are the old style of videos I love.

Glad it helped!

You're welcome!

+Tim Ford HI, could you help me in my project which uses this technique ? may I ask you some problems when I carry out ? through email ? tks in advance !

Shutter speed is discussed at the 2:48 section of the video. Flash power depends on what you are shooting (you would just need to experiment with it until you get it where you want it). I would start around 1/32nd power. Focusing is discussed at the 3:16 mark. I have a write-up on my website about using a stroboscopic flash if you'd prefer a text only version. You can see that here - timfordphoto.com/how-to-shoot-stroboscopic-flash-photos/. Hope this helps!

The simple equation is total flashes you'll be using (in my example, it's the 2nd number from the left on the flash I'm showing, which is 10) divided by flashes per second (in my example, it's the 3rd number from the left on the flash I'm showing, which is 5). So in the video, I did 10 divided by 5, which is 2. So I used a 2 second exposure. If you were doing something like 25 flashes total, with 5 flashes per second, your shutter speed would be 5 seconds (25 divided by 5). Hope this helps!

@@timfordphoto Thank you, for the quick and precise answer all clear! Kind

I honestly don't know, I'm not too familiar with the Panasonic line of cameras. My only experience with this flash has been using it on either a Canon camera or a Sony A7R (which does work, by the way). The flash settings are all manual though, so if you discover that your Panasonic can fire the Canon flash, everything else should work just fine.

Tim Ford Thank you very much, some blogs say if the flash settings are manual then it should work fine. Another question if I may, do I need the flash trigger if I'm only behind the camera and not the subject?

You need a way to fire the flash no matter what, but it can be on the camera. As long as the flash is pointing at your subject at an angle that works for you, it should be fine. Apologies if that was confusing in the video.

Try using manual focus. I know it's harder, but that's the only way to be sure the camera won't try to focus on the background. It'll take some trial and error to get it where it needs to be but it's worth the hassle.

@@timfordphoto I am using manual focus. It looks like my hand is transparent. Maybe a bit blurry but literally transparent and the background stands out much more than my hand

@@trancer03 Can you tell me what your camera settings are other than manual focus?

@@timfordphoto ISO 100. F5.6. 35mm lens 5 second exposure. 1 HZ 5 times

@@trancer03 How fast are you moving your hand? You can actually move it pretty slowly and it should still work.

You’ll need to do several test shots In order to figure out your f-stop settings, although you do want to stay away from anything lower than around 5.6. Lower f-stops mean shorter depth of field, which in this case is a bad thing. You are shooting something that has a range of motion, so you are better off working with an f-stop that gives you a bit more depth of field so that everything remains in focus. You can also use ISO to adjust your exposure, though these shots have a lot of black in them so if your camera doesn’t handle high ISO very well, I wouldn’t go above 800. I shot my test shots at 200 ISO. You’ll also need to determine the best placement of your flash. In my case, I had the flash on a light stand at around four feet in height, and it sat about a foot and a half away from what I was shooting (and off to the left). You don’t want the flash too close to your subject, otherwise you’ll actually see the bursts of light from the flash at the edge of your shot. Watch the video to better see where the flash was placed. For the shutter speed, you need to do some very simple math. The goal is to have the shutter open for as many flashes as you have the speedlite set for. In my example, I’m doing 10 flashes total, with the key being that there are five flashes per second. So to figure out how long to have your shutter open in order to capture all ten flashes, just divide the total number of flashes (10) by the flashes per second (5). In this case, the shutter speed would be 2 seconds (10 / 5 = 2).

Thanks a lot. .

Try not moving your hand quite as fast if motion blur is an issue you are trying to avoid.

Settings were ISO 200, f/5.6.

Well, the comments section can be used to ask questions....
