Allright NS,

I was helping my buddy film for his new edit on the glacier, he was fish and I was long. He has the 60d and I have a T2I. When watching his fisheye footage, I noticed it was considerably darker than fisheye footage I had taken in the past, and we both have the Rokinon 8mm. He had his aperture set at the F 3.5 and it was still really dark. He said he sets his white balance using the "wheel" on his 60d and this makes it darker. I was just wondering what he was doin? I set my custom white balance and still had to bump my aperature up to F/13 to get a darker look. He said he has no filters and I don't think he has magic lantern and I'm also shooting at ISO 100 and 250 or 320. I'm just hoping to get less over-exposed video on the glacier without blowing up the aperature too much?

Point it at the snow, expose the highlights (the snow) to be 1 stop over, and have at it.

Yeah, if you're at iso 100 and f11 or so you shouldn't have to put your shutter over 1/500.

i feel like you really want some sort of ND filter/fader while filming on a glacier

Yea he must have bumped up his shutter way high. I really do want to invest in an ND Fader filter for my Tamron, but from what I understand they don't really fit on fisheyes so that won't fix the overexposure problem for that lens.

rokinon has no front threads cause the front element sticks out

He is using both. Seems the issue is with the Rokinon though.

Yea I'm using both lenses, sorry for the late response. I like the idea of ND Filters and ND Fader Filters, but I'm not really sure which one would be good, and how they are sized. Any advice? I've bumped my aperture up to F13 and Shutter speed to 320, as well as customized the white balance so i'm starting to get richer colors. I'm just wondering, do you think it would be alright to bump my shutter speed up higher to like 500 and then be able to lower the aperture to like F11, is this a good idea?

Def get ML and use the zebras as already said. I recently bought a Fader ND filter, I'd def recommend it! Awesome to help with exposure. I use the Lightcraft Fader ND MKII. I love it, it's awesome! Very high quality and worth the money. So nice to be able to adjust between 2-8 stops of light opposed to having to buy multiple ND filters. What I did and what I would recommend is to buy a 77mm filter and use step up rings for lenses below 77, This way you only need to buy one filter but multiple step up rings which cost like $5. This also helps prevent vignette on wider lenses like an 11-16.

I just use a ND .9 for filming skiing in the sun. Works great. And you want to keep your shutter speed double of your frame rate whenever possible. So 500 is too high. For 60fps do 125 and for 24 fps do 50. That is how you will achieve the smoothest picture

no? Sure you can do that if you want a natural looking picture with some motion blur if you're shooting action. Double is the minimum usually but you're free to go pretty high. I film skiing at 250 shutter speed for a certain look, and I believe Zac and Evan shoot somewhere around there too, maybe even higher like 320? You can go high on you shutter speed, you just have to make sure you don't got too too high or it could begin to look choppy

Zac shoots high because he thinks motion blur is gross

People are so picky about shutter. If you have it higher than double your frame rate, it all looks the same. It's either motion blur (which i dont like that much) or no motion blur. 1/250 will essentially look the same as 1/2000. I like shoot 1/188-1/250 for 60p.

Yeah I suppose your right for skiing. I just have that rule programmed into my head from learning to shoot narrative, and other relatively slow-moving subjects in school. I have always tried to follow it for skiing as well, I guess I prefer a less digital looking image or something.
