Fluid Movement with the EM5

    Built a homemade variable ND filter using 2 polarizers I picked up in a camera store bargain bin for 3 dollars each. Wanted to test it out today so I took a detour on the way to work, then again on the way home - to shoot some long exposures of moving water.

    Setup was an EM5, 12-50, wired release and a tripod. I set the front polarizer to get the reflection how I wanted, set the focus then turned the outer reversed polarizer until I got the darkness I wanted. Camera was on manual, ISO 200 and f8. Shutter speed was 20-30 seconds on bulb.

    Lessons learned: Next time I will bring a small flashlight so I can see what I am doing and so I can paint a little light on rocks as I see fit. Also while I know how to manual focus on my CV lenses, I couldn't figure it out on the fly with the kit lens....in the half dark. Lesson there is to set your gear up before you head out.

    Here are the shots, hope you all enjoy. Pretty cool what a small camera, the kit zoom lens and a 6 dollar VND can do.

    Very nice. Often, using two polarizers like that can introduce all kinds of color shifts, but it looks like that wasn't a problem for these.

    I disassembled the outer polarizer by removing the retaining ring, flipped the lens over and reinstalled it. That seemed to stop the negative color cast.

    Interesting idea. What made you think of doing that?

    The homemade vari ND? I read about it somewhere years ago.

    Very nice misty effect to the water. Mystical.

    I thought I had read here once, but I can't seem to find it, how on the EM5 you can get the LCD to "paint" the long exposure as you go along? As I read it, as the shot goes along the LCD goes from dark to bright and you can gauge the final image exposure based off what you see on the LCD.

    Is that possible or am I off my rocker?

    I have never tried it myself, but I also read somewhere that this is how the camera live view display works when the shutter is set in bulb mode. Is it not?

    BTW, the shots are very nice!

    what does the nd filter look like?

    An ND filter in general looks like gray sunglasses. They should have no color tint. A VND (Variable ND) filter is a two part filter where you turn the outer ring to adjust the amount of darkness.

    My DIY VND is simply 2 polarizer filters where the outer element has been reversed.

    Wow what a beautiful location. Here is SOCAL it's impossible to find places like this.

    Love the foggy look of the water too. :smile:

    places like that are everywhere where I live in japan. here is one of mine
    with the em5, cant remember what lens I had on though. I took this one in bulb mode I think, didnt need to was just playing around with it and the lcd refreshes so so can stop the exposure when you think its ready.
