This came up in a different thread (HDR legality), but to keep threads neat, here it is in it's own:

Are in-camera multiple exposures legal in basic/advanced? I think we need a clear answer to this. I am very much hoping they continue to be legal.

Related to this, what about in-camera image overlays? I am assuming they are not legal except under the so called "expert" rules; is that correct?

Aren't in-camera multiple exposures and in-camera image overlays the same?

Uhm, shouldn't that question be directed to site council rather than the community?!? LOL

Sorry, I couldn't resist. :P

No, they are not.

Multis are a preset number of exposures, shot in sequence, and the camera stops the "multi" function 30 seconds after the last shot, whether the sequence was completed or not. At least that is the way it is with the D200. The ability to make multis in-camera is (at least for me) one of the attractions of the D200.

Overlays are taking two separate RAW exposures and combining them in camera. They may or may not be made in sequence. In other words, they can be an image from a week ago and one from today, combined.

Well, thanks! You don't look weird yourself :-) [whatever]

legal in basic, my entry was validated

As I posted in the other thread, the end result of a programmed multiple (consecutive) exposure series, and of an overlay are identical. They both result in one output file. So my recollection of recent history and discussion leads to this conclusion for Basic:
- Multiple consecutive shots combined in-camera (multi-exposure function) are allowable in Basic
- Overlays done in-camera are allowable (they must be, since they can't be distinguished from multiples), with two caveats:
1.) All images must be shot within the challenge timeframe
2.) No use of pre-existing "clip-art" borders or other stuff, as a couple P&S digitals will do now.


It's almost a given that with the ever escalating capabilities of in-camera processing, at some point we will have to abandon the "anything in-camera goes" philosophy for Basic at least.

Visually they can't be distinguished, but EXIF data is different for them, and it would be difficult to confuse a multi with an overlay.


Or, maybe stop trying to control everything and make a rule about everything. Just a thought. :)

This will get real interesting if Adobe ever releases something like "Photoshop ICE (In-camera edition) :-)

I'm with ursula... maybe things should be laxed instead of constantly tightened.

Well, essentially they have been. The ruling has always been "anything in-camera goes." As in-camera processing has gotten more sophisticated, so has what is allowable in Basic. At some point, however, if we keep allowing more and more stuff, there's less and less to distinguish Basic from Advanced. We will almost certainly have to push "reset" at some point, or change our view on what's considered "Basic."

Even more interesting if they get it to run on OSX in the upcoming iPhone... with its 2Mp camera.

That is true.
However, I don't think it is reason to make more rules, especially when the rules are slanted towards a particular way of thinking to begin with.

Maybe a distinction will show up over time. Maybe the distinction between basic and other editing forms doesn't have to be software based. I don't know.

I had that same thought myself. And even if Adobe can't be run on it, I'm sure Gimp will be ported to it.

why wait for the iPhone when today's windows mobile phones can already do photo-editing in-camera (i mean, in-phone) lol
