Raw would be the original

| but if you shoot in RAW + JPG mode both have intact exif. |

When saving RAW + JPEG is there a way to tell if the JPEG was the original? I don't know of any such way. If so, only the Raw will count.
Here's another idea:
DP could require RAW be enclosed with each submission. The Originals would only be saved for the duration of the challenge + DQ time, then deleted. Net increase in server space is minimal relative to the total.
Two advantages:
1) A DQ request would not need author response in 48 hours (and some inadvertant DQ's).
2) EXIF's could be automatically scanned to check date. |

How about on the submission page instead of having to enter the location of where you took the photo, you have to enter the date you took the photo. If not in the required date range then photo not accepted.
Of course you could enter a false date, but your exif would give you away. Just a thought... |

| I think that's what the field called "Date of Exposure" is for. |

That would seriously hamper the minority still on dial-up (or with slow broadband uploads) from participating.
Also, many places in the world meter internet usage (they pay by usage, not per month), which would increase their cost of participation with no real benefit.

it's not that we don't like this idea. however, the final files that are submitted to DPC would have their EXIF altered by whatever application made the edits. therefore, the EXIF isn't truly original, and we have no way to confirm that it is indeed the correct information. |
Just overwrite the modified exif with the original then. I'm still at a failure to see how anyone would detect that; what does SC actually use to verify that the exif is correct, unmodified, and for the correct photo?
There was one person who recently had a rash of entries DQed and subsequently banned (afai can tell). Obviously the changes to the exif files hadn't been caught as the person had several ribbons, each of which would have required validation, so the person was found out via other means. Unless I'm wrong, which could also be likely.
I'd like to add support for the suggestion that if EXIF data were parsed when included it'd make everyone's life easier, aside from the inital coding. It's pretty ridiculous that people have to manually enter the data the camera saves for you. |

The EXIF data is gone or modified before it ever reaches DPC. The only way to parse the camera data would be to upload the original at the same time. |

Not on everybody's images though, as was mentioned earlier in the thread. Even if it's not accepted for DQ validation, it could still be used to populate fields, and be used as a an early warning to people posting when the exposure date is wrong, assuming they still have EXIF data. |

I generate my JPG's directly from Rawshooter for the most part. I would normally have EXIF data included because it saves me typing later on. I agree most would not have it. |
