Yea, it's called "pull focus"
Pete is the above wrong,? it's a typo or sommit surely????????? Chris is asking about an apeture DOF pull. erm I think ??
Mate not being pedantic trying to work out how to make a vid tis all I know nothing but it's bestI'm able to understand the terms
Pull focus is the same as focus pull ie moving point of focus from one point to another.?? that is right isn't it
sorry mate I'm spinning from video input but had to ask as it might not be a typo, you might be right I need to understand
You can use a depth of field pull. You can do it by using a variable ND filter or ISO to compensate for the change in aperture. You need to be able to vary the ND or the ISO smoothly or you are going to get steps in the exposure variation.
AH , more specifically can you elabourate at all on how auto ISO can be used to compensate for an DOF change .
I normally shoot stills my camera body is a 1dx mark ii I shoot wildlife . Due in part to C19 sheilding etc I find myself making video , which I have never done before. I normally work with natural light all these vids are made at night. Simply I have a mum fox that scavenges our bird feeders has done for ages, I just didn't know she brought her cubs here. I can film then from feet away and am trying to absorb every thing I can as fast as I .can
So basically from just siimply shooting, i'm aware I'd like to have a method of varying DOF and also aware just changing the F looks horrible . Is this as simple as using auto ISO. . Is auto ISO a crude start point that will need more work in post? Does one severely limit auto ISO options to pre determined f changes? Andrew you shoot something very very different to I. The ND grad is a non starter for me ,I had wondered about ISO being an option. My subjects at this distance allow me to barely move a lens ,they is simply no way an NG grad can work but ISO in auto seems logical. If I can understand a working method I might be able to adapt it to my needs. Sorry for the Q's I could ask a million at the moment, I need to grasp the basics of so much,so fast
many thanks if you reply.
Chris
@sirch sorry if this is a derail, I feel like i've commandeered your thread bro, my humble apologies . It just seemed so silly to ask elsewhere start another when the topic is what I wanted to ask about and am also slightly confused by Pete's post
thanks lads
