NTSB made an educated guess on this one - recordings from the GoPro of previous flights, including a 6 minute flight in the pattern immediately preceding the accident flight did show flash photos being taken inside.
It would be interesting to find out if they did recover photos from cell-phones, but would that require warrants? Dunno.
edit: Here's what NTSB found on the GoPro for the 6-minute pattern flight just prior to the accident:
>>>
GOPR0021.MP4 – Night
Video recording began at the hangar area. A new passenger, Passenger #5 was in the cockpit with the pilot. The pilot's associates were seen standing near the hangar behind the airplane. A sound similar to the pilot pumping the airplane's fuel primer is heard. The pilot started the engine. The following ATIS recording was heard through the GoPro's internal microphone:
Denver Front Range Airport automated weather observation zero-six-zero-five (0605) Zulu: weather – wind calm, visibility [seven], ceiling three-hundred (300) overcast, temperature one-four (14) Celsius dew point one-three (13) altimeter three-zero-two-zero (30.20).
The pilot taxied to a runway. It appeared that the pilot conducted an engine run-up during the taxi. The pilot was seen checking for freedom of control movement in the control yoke during taxi. The pilot began the takeoff roll and departed the runway. During the climb out portion of flight, the pilot uses his cell phone to take a self-photograph. The camera's flash was activated and illuminated the cockpit area. The pilot's cell phone appeared to be on a user screen consistent with a camera application. The pilot landed and can be seen using his cell phone during the landing rollout. The recording appeared to have ended normally.

During the RV-7 crash (N820RV) here I was hired to investigate with the NTSB gal, some things transpired...
I have NEVER been involved in stuff like that so I don't know what normal protocol is but here is my view...
We spent most of one day cutting the motor off, pulling components off like fuel pumps, valves, prop governer, ignition, some other stuff and a COMPLETE motor tear down.. While she was doing that I as asked to remove as much of the (people parts) as possible and remove interior stuff..
She mentioned several times his wallet and cell phone is still missing.. We had already removed the baggage and other stuff from behind the seats and all that was left was the front seat area.... When the guy built the plane he fabricated a small console between the seats but since the lady had totally crushed that area during impact alot of stuff was just twisted metal.
I suggested for her to ask the family to call the cell phone so we could home in on the ring sounds,,, The NTSB gal didn't like that idea so I kept digging and prying siht apart.. Finally I found what looked like a pink object and sure enough .. it was the cell phone crushed against his wallet, between the remains of the front seats and people parts..




..
So I call her over and tell her I will take a crowbar, pry open that area and she can grab the phone and wallet.. After 20 minutes or so she has both in her hand and she takes them to a table I had set up a couple days before so we could weigh stuff as it came out of the wreckage... To me, it CREEPY to dig through other peoples stuff.. For her it was another day in the office.. I sat there as she dug through the wallet and she kinda mumbled a play by play of what she found....
ie...
Credit cards, business cards, cash, receipts, etc etc.... We then knew where they had spent the last few nights from the motel receipts, how much fuel was purchased and where, food bought etc etc......
I am a complete dummy on smart phones as I can barely dial my simple cell phone and cannot even text... She got hold of the phone and was DAMN good at reconstructing all calls, pictures and videos.. I was amazed at the database ' archive stuff in smart phones... Before that day ended she knew just about everything she needed to see.....
So,, In closing,,,,,,,
Apparently it does NOT take a court order to recover data from a phone.. IMHO...
