So I know we cannot take a photo of a duck swimming and edit those together such that the duck is moved in each scene.
BUT... could we take a photo of say a light bulb, or Christmas tree lights in the "on" state and then a photo in the "off" and merge them, ala HDR to create a more complete image of the tree/bulb? Nothing moves for example... except in the incandescent bulb there may be something scientific going on with the filament or such.
Thoughts?

| One of the allowed purposes for multiple exposures is for exposure latitude, so that might indicate that this could be judged legal. However, the presence/absence of the lit bulbs in the image might also be judged a change in content in the scene, and thus illegal. Personally, I think that nothing entered, nor left the scene, and nothing moved, therefore it should be legal. Not that my opinion matters. |

I'm sure it would be legal, myself. I think it would be insane not to be. If they are THAT picky it's time to dump the rules and loosen our sphincters a little...
ETA: think about this: It's absolutely legal to do a single exposure with the lights turned on/off partway through. So, to do one exposure with the lights OFF and do another with them on/off has GOT to be legal, eh? You can see where I'm going with this....

Hmm... I think I'll be the great dissenter here.
If turning on a bulb is allowed, then it would logically follow that we can also use this to stack an image to enhance something like blurred water.... Essentially nothing in the composition has changed, only the portions of the water which are lit/unlit change between frames.
You can probably see where I'm going with this.... |

I think blending two versions of the tree with the lights on and off is the equivalent of HDR, and could probably be done with that method alone and the lights on all the time.
Using multiple exposures to create blurred flowing water would not me legal (IMO) because
1. you are creating a "new feature"
2. the water has moved between frames (or there would be no blurring effect) and so the scene has changed |

I've got a suspicion that I've seen landscape HDRs entered which have the clouds interestingly blurred because of movement. But I might be wrong.

Minimal natural blurring due to movement between burst exposures for HDR is one thing, deliberately blending different pictures (presumably with similar lighting) where the subject has moved in order to create an entirely new "subject" is another.
FWIW I speak only for myself, not for any other SC members ...
BTW: if this relates to the "Holiday Card" challenge, that is Expert Editing and combining the two exposures is completely legal (as would be the blurry water idea, but under any of the other editing rule sets).

The electrons are moving in one. but not the otherâ€Â¦just like the waterâ€Â¦
