Hey, consider it an exercise in problem-solving. Giving the brain a workout is a good thing, no? :)

R.

What if you shot with the incorrect date all of the time? Instead of shooting for the current challenge you go back a couple of weeks to see whether you have anything that will work each rollover? Plus, as far as I can tell, only the original of the image entered is required by the rules. I don't see that they can make you provide additional originals.

Unless you were skilled enough to have high-placing images in back-to-back (or nearly so) challenges, with one image id# not matching the other or possibly even having the image id#'s in reverse of what they should be logically based on the challenge run time.


Also having to take into account if different camera bodies were used... :)

Let's refine this thought experiment, shall we?

Ok. Let's say that my only goal is to use this technique only once and specifically to win a ribbon. I go out and buy a new camera and a new CF card. I set the date to exactly one week in the future. I pop in the card and format it. At some point, I stumble across the most spectacular scene and take exactly one shot. To my amazement, a challenge appears the following week that that one image is perfect for. The date in the EXIF is within the challenge dates. I edit and submit. How do they catch me?

Oooohhh! THAT would work! :-)

Wouldn't there be a date on the actual RAW file, as viewed in Windows Explorer? I mean in the "Date Modified" Column.

Maybe I didn't download the image until within the challenge dates.

I'm confused. Are you talking about the image numbers used in the file names (ex. IMG_5395.CR2)? If you entered one challenge with IMG_5395.CR2 and then next week with IMG_3192.CR2 it could just mean the photographer shot a lot between challenges.

if you go through all of this effort to win a virtual ribbon, i'd vote you get to keep it.

...but we'd still know. :P

I can't find it in my EXIF.


not all makes and models store the same information -- and not all of them store it in the same place.
06/03/2009 03:53:16 PM · #36
A clue!

According to mucky, they'd still know even with the only image the camera and CF card have ever taken/recorded.
06/03/2009 03:57:06 PM · #37
Is the EXIF the only place to look, or is there metadata attached to an image somewhere else that I don't know about? Maybe there's a way to see previous date settings? Like it would be obvious that the date used to read one value and now it reads exactly 1 week later? Even then, who's to say that the previous date was correct? Maybe it was a week slow?

Don't you have some pictures to go and take or something?
06/03/2009 04:00:50 PM · #39
I do, but I need to know what date to set my camera to first. :)
06/03/2009 04:02:16 PM · #40
I wish someone askes to see the photo I took on 5-22-2009 with today's 6-3-2009 date.
06/03/2009 04:03:25 PM · #41
Can I see it please?

Thanks

This is it

Cool shot! I don't see any EXIF data on it, though, so I can't confirm your story. :)

I took two photos one after another with two different dates then a third of the same with the first correct date. I can prove it that I predicted rock contest coming.

Forget about ribbons... I want the flipping lottery numbers for next week :-)

Example scenario:

On May 26th, 2009 you set your camera's date ahead to June 2nd, 2009 and take a photo with file # IMG_2450.CR2.

On May 27th, 2009 you set your camera's date back to May 27th, and take a photo with file # IMG_2500.CR2. You enter this photo in a challenge (call it Challenge One) with a submission date period of May 24th thru May 30th. All is fine with this photo.

On June 3rd you enter a challenge (call it Challenge Two) with the photo taken on May 26th (although it's EXIF says June 2nd) - file # IMG_2450.CR2. On the surface it looks fine as the challenge submission date period for this challenge is June 1st thru June 7th.

You're on a roll and end up in 5th place for Challenge One. Your photo is validated per request (places 1 - 5 are automatically requested). Everything is good.

Challenge Two is rolling along smoothly, then something you did in post-processing triggers a validation request. You submit the original for review. Looks fine date-wise, however, how could you take a photo on June 2nd for Challenge Two with a file # that is earlier (#_2450) than the file (#_2500) for Challenge One?

Yes, SC would have to be looking for it for any red flag to be thrown, and you could have an alibi that you reset the numbering on your memory card, etc...

Certainly would be a lot of effort I suppose and like muckpond said "...all of this effort to win...I'd vote you get to keep it". :-)

On the other hand, purposefully altering EXIF data will result in a permanent ban, so there won't be many folks admiring your ribbon ...

Hmmm...that's true, but would that be technically "altering" the EXIF data? The camera date is changed physically, but the EXIF hasn't been touched by any editing tool designed to alter it.

If what you say is true, that's good to know. :-)
