Slow Motion Question (Hair)

[Jon Schellenger]

Hey everyone!

Question- I have been fooling around with the slow motion on the red, and I have a question about slow motion and motion blur.

If I wanted to shoot a girl with long hair advertising a local start-up hair product, what shutter speed should I use? I have played around a bit, but I am curious to see if you all have done something specific to capture good slow motion on a persons face along with hair. (Any tips?)

After playing around with the speeds, I feel that 90 frames per second is a good speed for what I am attempting to do. I know it is all about establishing a look and everyone has a different opinion on this, but I am wondering what most of you are doing. If you were to shoot a girl shaking her hair back and forth in slow motion, would you bump up the shutter from 48th/sec to something over 100th/sec to cut down the motion blur?

Do you all have any cool tips about shooting slow motion that you would mind sharing?

Thanks again everyone!

Set the shutter to relative so you don't have to think about it. Then you'll have the right amount of motion blur if compared to a film camera set to higher framerates with 180 degree shutter.
Don't think you want to have motion blur in slow-mo. It just looks out of focus.
Also I like Red's option of shutter display values. I think degrees are so much easier to relate to.

So test relative shutter displayed in degrees and see have you like it. That's my advice.

Kjetil,

Okay, I will begin to research this. I agree that I do not want much, if any, motion blur during the slow-mo.

I will try a few tests on this tomorrow. Thanks again for your reply.

I suggest shooting it at 120, your highest frame rate. You can always throw away frames in post and choose the speed that works best. This will give you the most options and possibility of a slow-mo to slower-mo post ramp.

as another little tidbit, I try to always shoot slow mo at a faster than 180 degree shutter, just doesn't look right to me otherwise

Hair thickens up at about 50to 60 ( if the hair is nice and thick and is only bouncing turning)

With thin hair being blown you might need 120 (although if you are doing a 16:9 extraction it better be a close up or stick to 100 and be carefull)

with hair I would default to 180degrees until you are sure of the look you want.
