Tips for Mastering In-Camera,Double Exposure Portraits

Whisky-dave wrote: Ok, so they do two frames, then merge or blend them into a single file. That's postprocessing, not really "double exposure" in my book. It simply emulates it, but it is not it. are you channeling eric? it's double exposure, without any emulation whatsoever. It's not a double exposure it's two seperate exposures on two seperate frames. Which is what happenes whenever you take two photos. Then they are merged together something that doesn't happen when taking single exposures. double exposure is always two separate exposures on two separate frames. that's why it's called double. bonus points: how many exposures in a triple exposure? Is HDR a multi-exposure technigue I'd say yes but it isn't the same as what was done in film multi-exposures. the only difference is they're of the same subject rather than different ones, and that there's usually more than two images for hdr, although two certainly works. So I'd say it was emulation of double exposure, or it could be a simulation if exactly the same method was used as would be used in film. it's neither emulation nor simulation. it really is double exposure (or triple or however many there are). also, a double exposure of the same scene will have less noise, The vast majority of double exposures wouldn't be of exactly the same scene otherwise they'd be little point in doing it, unless for HDR of course which is when you do take multiple shots of the same scene. it doesn't matter what the majority does. multiple shots of the same scene will reduce noise. once again, math. and it's a lot easier to do it in camera than later. Only with digital not with film, as you run the risk of the film moving. push the little button and the transport is disengaged. sheet film users don't need to do anything. that's also part of how google night sight works. What part ? the multiple exposure part. |

Wrong. It is two separate exposures on the same frame. Which is what a digital camera does not do, so it is not double exposure. End. -- Cheers, Carlos. |

Which is what a digital camera does not do, so it is not double exposure. it's two separate exposures in the same memory, before it's written to a raw or jpeg image, thereby making it a double exposure by any definition. at the end of the day, it's two clicks resulting in one image, just as it's done with a film camera. instead of pressing a mechanical button on the bottom to disengage the film transport, you toggle a setting in the menu, which disengages the memory writing. it's also not limited to two exposures, which is why it's called multiple exposure, and also far more capable than anything film could do. camera companies don't agree with your ridiculous definition. nikon: https://nps.nikonimaging.com/technic...more/img/img_0 9.png https://nps.nikonimaging.com/technic...more/img/img_1 1.png canon: https://support-my.canon-asia.com/img/G0227382.gif https://support-my.canon-asia.com/img/G0227383.gif https://support-my.canon-asia.com/img/G0227386.gif fuji: http://fujifilm-dsc.com/en/manual/x1...p/images/osd_s m_multi-exp00_en_x100t_320.gif |

Not even the one in the camera. To be valid, the sensor would have to be exposed, and then, without reading it, exposing it again. Are they really doing it? that's not required, nor would it work particularly well. -- Regards, Eric Stevens |

Nikon, Canon, and Fujifilm (and probably others) have a multi-exposure feature/mode which allows for two separate exposures, on two frames, which are blended into a single file. It is a bit of a novelty and nothing that cannot be done in post. Ok, so they do two frames, then merge or blend them into a single file. That's postprocessing, not really "double exposure" in my book. It simply emulates it, but it is not it. are you channeling eric? He is being precise. You are not. it's double exposure, without any emulation whatsoever. also, a double exposure of the same scene will have less noise, and it's a lot easier to do it in camera than later. that's also part of how google night sight works. -- Regards, Eric Stevens |

Learn to write with precision. i did, long ago. |
