hmmm... my phone gives me the option to upload to picasa. But it's a 1.5 mb file, but it only brings up a small image to picasa, and I don't see a way to get a larger version...
Can't you plug your phone into the computer so the folder on the SD card show up as a drive? That's what I do.
When I am out taking photos with my big-boy cameras I am tending to forget about the phone cam challenge and then realize after I have moved on that I just missed a good opportunity for a phone cam shot.
I'm still confused about "complete exif data." How detailed does it have to be to be considered complete? This puts a wrench in what I was considering as possible entry. I have an Epic4 Smartphone and many of the Android apps show what I thought was exif data when you look at it under "properties." I often use FX Camera and Vignette Demo and there is some exif data when using those apps to take the photo (not editing it after the fact) so I thought they would be fine. Now I don't know.
I think the time, date and camera model should be sufficient. Detailed exif data is not a strong point of phone-cams.
Here's the quandary. One can import photos to one's iPhone. You can edit them a bit and then export them back out. There won't be any iPhone exif data attached to the file. But, an image can be from "anywhere" if we just accept someone's word for time, date and camera model. That's why there should be a requirement for a validation file from one's camera phone.
Just an example, the following file was captured with a DSLR, imported to my iPhone, edited and exported back out to my computer.
The visible exif data does NOT tell anything about capture device.
geez...I am almost nervous to enter now. I do a lot of my iPhoneography with every EXCEPT the native app. I am guessing its best to shoot them with the phone (native app) and then edit them on my system. (Keeping the original intact of course)
So what are you saying? Can someone take a shot with a 5D...import to Iphone, export and it looks like it came from Iphone on Exif?

Ok, I'm confused...as usual...How do I know if my phone will work with this challenge?
I guess you can send in a sample file with a ticket and have someone on SC check the EXIF to see if it meets the necessary specs. I may have to do the same thing myself as I've never (intentionally) taken a picture with a phone, at least not of mine.

Have done so, will see what happens, thanks.
I have also found there is a mention of EXIF on the photo properties, maybe this is what I need, either way a photo has been submitted, it may still be unsubmitted!
this will definitely be an interesting challenge to validate if legal.
photos from both my 2g and 3gs phone have exif data imbedded but i'm wondering about the phones that don't have that data embedded, will those be dq'd?
i need to try and find pics from my samsung slider phone and see if there's any data in those pics.

Yes.
The "import" part is probably not needed, you could probably simply change/forge all the EXIF data directly. Then obviously make sure that the resolution and file details (dates) are all adequate (they can be forged too), and there is no easy way to tell whether the file really comes from a given phone or not.
Even cryptographically signed files from Nikon or from Canon have been cracked (the secret key hidden in the cameras has been extracted).
Forensic tools are now working on the photo's content itself, in order to mathematically detect modifications (in short, content modifications induce inconsistency in the mathematical statistics properties of the image, and also induce inconsistency in physical laws of sensors, such as noise, luminance, etc.). Also, each type of sensor (brand, model, etc.) has given physical properties, which can be analyzed in the photo then compared to a database in order to estimate what type of sensor has shot it.
I have a Samsung phone that is 6 years old and has no "camera" It can be used to make phonecalls and receive phonecalls and one can send and receive SMS messages with it. I have no need for any other features.
I have an Olympus E1 DSLR camera that is 8 years old and has no build in flash, no video, no scene modes, no art filters, no live view, no flip-out rotating LCD screen. It can be used to make photo's. I have no need for any other features.

Just remember that if we catch you at anything like that, you'll be outta here and never coming back ... seems to me like a lot to risk for a few colored pixels on your Profile page.

Of course. This was not an advice in any shape, just an answer to a theoretical question.
This will probably inaugurate the start of DPC becoming a mobile phone camera challenge site. DSLR's and other regular type's of camera's as we know them are on the way out. The future is mobile as they say. There's already lots of mobile phone cam challenge sites out there anyway. Guess I'm gonna have to hang up my old gear and look for another hobby. Maybe I can start concentrating on fishing again. I was always much more successful at that then photography in any case.

Oh I don't think so. The phone crazy is quick and fun but doesn't replace a camera. Most people that just use it to upload to Facebook or Twitter aren't really photographers. They are just capturing a moment and posting it. I rather like the editing process myself. Give me Photoshop or give me death!!
I can't find an option to add my phone(Nexus S) as a camera in my preferences. Is it alright to just upload it under my default camera and put the phone name in the description? I read through the rules and this thread but didn't see any mention of what to do.

I sent a pic to SC from my phone and they have added it to the list and confirmed that it retains EXIF data, You should still have time to get this done, it took me a few days.
