Any evidence for digital

[igercelman]

I don't know that forum is true for that matter.

How can I prove that image is taken by me at court of law?

If I use film, there is no problem. But if use digital, I don’t know which evidence is trustable.

I think exif data are not trustable, because I can re-write that data.

May be RAW format is acceptable as most trustable evidence.

Are there any experience and idea about that?

Best regards.

If the issue is about copyright (you want to prove that you took a photo and sombody else stole it), then maybe being the only person who has the original RAW file might be a good case.

I would say that a .crw would be trustable for now, but who knows what features will be on the new PS8 raw convertor.

As far as I know... nikon is the only one putting out an digital camera that the file can always be put in it's original state and is allowed in a court of law.

So if digital can't be trusted because it can be changed, surely film can't either!

The Cottingley fairies were done in camera in the 1890s and still don't look obviously faked. I'm rubbish in the darkroom but I know some people who can do some amazing things. Even allegedly 'straight' pictures are dodged and burnt and the contrast etc. adjusted.

I guess there is something pschycological about film that digital will never have.

The best proof of course is a witness or two - take some mates along to watch you shooting the pictures and verify that they are yours.

I submit photographic evidence in trial court often, about 10% film and 90% digital. Cross examination is limited on the photographs and usually consists of "is this a fair and accurate representation of what you observed" Many years ago cross included numerous questions about the workings of the camera, settings, film type, processing, etc. Have yet to have a problem introducing digital photographs.

I am curious about the possibility of reverse engineering.
First, take a digital shot, then print it.
Second, using a film, just copy the printed shot.

Can a scientist tell whether the original is digital or film?
Remember 12 megabytes surpass the film quality. Perhaps any digital shot over 12 megabytes can be converted into an "original" film, or not?

I've heard of people scanning slides and/or prints at very high resolution, changing things in PhotoShop, and then sending them out to a photographic-quality printer. Voila!
