high shutter, open iris = depth of field?

I'm trying to create some good depth of field with the 100a. My goal is to open up the iris, have a high shutter speed. I would like to run the tape at 24p. I was also wondering what type of effect this might have if I were to slowmo it. With the high shutter speed would it make things look too unrealistic?

I would be shooting in a club with some light,colours would blues reds greens with some tungsten filler.
I would test this out, but I am renting all my gear. I considered getting one of those 35mil adapters to achieve the affect That is given to film, but I don't think this company has those to rent.

Your thoughts are appreciated,
Andrei
 
the shutter speed shouldnt change the depth of field, technically opening the iris will give you the shortest depth of field while you can use the shutter speeds to control the exposure of your shot?

as for slowing it down? Well always remember, if your shooting 24p and you slow it down more than 75%, at a high shutter speed it will be very choppy and precise, as a slower shutter will allow for those in between blur shots making your slow mo more fluent. But choppy slow mo is also a great effect
 
Opening the iris all the way is a must. Then, you need to be on the long end of your zoom -- zoom in all the way (get your camera back away from your subject, and have the subject away from the background).

To control light, use the ND filters. Shutter speed will cut down on light, too, but as mentioned, it fundamentally alters the movement.
 
If I shot at 30fps and had the cd played back at a increased rate, then slowed down the video in post, would that be better then shooting 24p. Also, anybody know the increased rate of playback so when slowed down, it looks like 24p?

Thanks, and I hope that made sense

k page 37:

shooting at 30 P, " in post, you then play that 30p footage at 80% speed, and you get frame for frame accurate slow motion just like overcranking a film camera. Its very mild slow motoin, about 25% slower, but its the cleanest slow motion possible from a video shooting at 30P


For slower slow motion, you should shoot interlaced video at 60i..... Whats important about slow motion is that its smooth, and to get the smoothest slow motion possible, you ned to capture as many motion samples as possible. Interlaced mode captures 60 motion samples per second. When you import that footage into a 24p timeline, you slow it down to 40% of its speed, and your editing program will make a full frame out of each field."

when shooting 30P use 1/60th shutter speed, and when shooting at 60i, use 1/120th shutter speed.

kewl
 
Papa- How much should I speed up cd if I were to shoot 60i and slow it done by 80%. Would that mean I increase the speed by 20%

Thanks, looking forward to your response,

open 29 frame timeline

put in your 60i footage and then go to speed and put it to 40% ( this is what i have to do in premier pro 1.5 )

save that footage, then import it into a 23.blah blah blah timeline, it should be 24 fps and nice and slow, smooth,.
 
I apologize, when I meant speed up by 20%, I mean the audio track that the artist will be performing. Thus when I slow down the video, his lips will be in sync. Sorry for the confusion.
 
oh ... ummm......... anyone?

not sure exactly how to calculate that out, but im sure someone knows.
 
hmmm, sorry not sure about that one,

or at least how to calculate it, anyone care to give it a shot?
