Forensic DSLR Camera Question - Nikon D90 & GPS 090630

I'm trying to use a camera to photograph an image and to prove that it's authentic and not photoshopped. Can anybody help me here?

I am very interested in hearing your results. Because you have opened up a very interesting question. One that I never actually thought about before. And I am about to buy a new camera, and I have narrowed my selection down to two candidates - the Canon 50D and the Nikon D90. So one of those two will probably be my new camera. I won't base my decision just on this "forensic" feature you talk about, even though it may be a good thing to have some time. It can be a really useful feature, indeed.

@Altair8801 The current crop of Canon SLR cameras have this forensic feature. I'm not sure if the D90 has it... I still don't think it does. It does have a GPS feature on it, though. What it does is that it writes the GPS coordinates to the metadata at the time or recording, and that's what I'm using to record an event at a specific place. That's why I need something that has a forensic feature - to prove that the file wasn't photoshopped or manipulated.

So, what was it you'll like to take a photo of?

after 7 months its time to reveal, i thought so.!

[Spencerian]

Tiddojr - I can't reveal it just yet until I make sure it's fool proof. Trust me, it's worth it.

Did you see a UFO? An ALien??? hahaha

[Spencerian]

Starzship - I saw something really rare, and I need to photograph it to prove it! When I shoot it, you'll see it for sure.

Keep a log of everything you do, any changes you log it, it shows that you have a paper trail, and nothing was tampered with.

My advice.

For court cases use camera with film.

[Wamfox]

it would be a film camera

hmmm, tough one. in todays digital age i figure thats hard to do.

[blissologist]

@Spencerian Maybe it's already been said, but If it's just one photo. Hire a notary and or third party to witness or take the photo and give them the file until the court date. If it's multiple photos at multiple sites the metadata should be enough to be acceptable in court unless it's something super serious and the lawyer is trying to pick it apart. If that was the case i would hire a pro third party.

what is the lens?

[bite0020]

just shoot in JPG? The meta data should hold time/date/geotag etc

[MrGeotagger]

The GPS-Data is written to the EXIF header of the JPG and/or RAW file. Photoshop is a very bad tool to modify EXIF data. But there are hundreds of tools to do so (ExifTool, ...)

In my eyes the Nikon GP-1 is crap. Not only because of the terrible cable for Nikon D90, D3100, D5000 and D7000 which stands straight out of the body (Dawntech and Solmeta Geotagger have L-shaped connectors!)

GP-1 lacks a lot of features like compass or indoor function

[MrGeotagger]

AFAIK Nikon D90 has no "forensic" feature to proof the pic is unchanged. Canon has, but ist is cracked: h-online.com/security/news/ite­m/Russians-on-the-moon-Canon-s­-image-verification-system-cra­cked-1145443.html

My standard windows program tells you if the image has been messed with or not.
