Picture taken

If someone takes a picture in the dark to report a crime can the gardai identify someone from that photo?

Who took your picture OP?

Scioch

Depends on whether or not you had the flash on I'd say.

Pdfile

Perhaps that is the crime the OP is worried about.

Exposing your "little friend" to the laker girls again OP ?

If they had night vision, your screwed!

chicken_little

Pdfile is reassuring anyway :P seems incredible but a friend asked last night and i was interested to know if theres like a massive photo file for this? Or do the gardai not have the technology etc

your average photographer probably has software similar to what the gardai would be using.

I'm sure they can as long as the person they are looking for is in the photo

if the photo was taken in the dark with no flash, it might not make a difference; the focus might not have locked due to low light, and the shutter speed would be long, possibly long enough to blur the face.

Depends on distance, film iso, resolution and other factors.
Not a simple question just to say yes or no to.

This sounds very like one of those 'If a Tree falls in the woods and no one is around to hear it...' philosophical questions. What state of inner zen are you expecting to reach by pondering the question OP?

Have you seen CSI? They can enhance a pure black photo and see the reg of a car from a mile away! :pac:

I imagine the guards recognise repeat offenders by sight.
But as others mentioned, at nighttime without a flash, a camera needs a longer exposure to take a picture which means more blurring.

(nerd hat on) or needs a high ISO (stills camera) or night vision mode (video) .... a high ISO/Night Vision mode would not require a long exposure as they are designed to capture images in low-light situations.

in order to answer we need the make/model of the camera and actual luminocity of the area (how dark it actually was) - and we can calculate the required shutter speed/ISO ratio required to expose a still subject and/or a subject moving at a rate of 1m/sec or different speeds.(/nerd hat off)

Blasht 'em with p*ssssss !!
