Jared Polin: Jared Polin froknowsphoto.com. We’re up on the roof right now to demonstrate how a variable neutral density filter works, and the importance of why you want to use it? Right now our settings are set to 100 ISO 150th of a second at F22. And what’s happening here is we do not have a filter in front of the camera cutting down on the amount of light, so we have to go to F22. Look at the background. It’s almost sharp. Now, that’s not the worst thing in the world, but if it’s any brighter than this, you have to bump up your shutter speed and you start to get into issues where you don’t want your shutter speed that fast. So what we’re going to do now is we’re going to put the variable neutral density filter on the camera.
Go ahead Steven. As he screws that on, what you’re going to see is that it’s going to almost go well, it’s going to go pitch black. And the reason is, is this filter is going to cut down on how much light is getting into the camera. So now we’re going to go to F4 right. Steven: Yeah. Jared Polin: So we’re going to F4. It’s going to cut back and Steven is going to turn the neutral density filter until its set properly to give us that right exposure. Let me know when it’s right. So now it just looks, it looks better Steven. Yes, the background you can see is blown out. This is the point of using this variable neutral density filter so that you can sit there and control the amount of light that’s coming into the camera. This is what you want to have in your bag if you shoot a lot of video outside. It’s going to come in handy for shooting long exposures in bright daylight if you’re just doing still photos, trying to get those waterfalls, trying to get the 4-5 or the F2.
8, but in bright daylight, the only way you can do this is to get one of these filters. Now this one is a Heliopan that I picked up at Allen’s Camera. It’s a $400 filter, but if we’re doing a lot of outside shooting like we are right now, and you need to cut back on that light because you want to have that 150th of a second which gives us that double what our frame rate is then we have to do this. This is what we have to do to get the shot. We don’t want F22. We wanted nice and blown out in the background so now we got the F4 and that is why we use one of these filters. So there you have it Jared Polin froknowsphoto.com. See ya..
