So... The last three months, life took over. I had to put down my camera for a while. Three weeks ago, i decided im ready to take photos again. So i took my camera out of the dry box and wiped away the dusts. Literally... Sensor dusts. More like molds, actually. The dry box wasn't so dry after all.
Anyway, it's a simple cleaning task. But not quite. There was dirt in places i couldn't reach. Like that one behind the viewfinder glass itself. I live in a tropical weather country.
I figured its gonna take a long time before i get my camera back if i bring it to the service center. So i took it for a ride and did some night photography. Long exposure shots. And whoaa! Hot pixels everywhere. About more than a dozen of them if the shot takes more than 4 seconds.
There is a built-in feature in my camera for hot pixel mapping but that one only works if hot pixels show up at one second exposures. This made me decide to finally let the pros handle my gear.
So it' gonna be a few days, probably a week without my toy. For no apparent reason, my wife is playing some country music mp3's. Trisha Yearwood. How do i live without you.
Anyway, i have some questions on pixel mapping. I have two very reliable and informed sources telling me two exactly opposite opinions on it. One is basing on his experience when he had his canon pixel mapped. The other one is a technician from a local camera shop. One is telling me that pixel mapping, since it modifies the hot pixels after capture, modifies the exif. The other one is telling me that since it modifies the pixel before writing the image to the sd card, the exif is preserved. Then the other one contradicts that the exif is modified in-memory (date updated becomes greater than date taken) so the exif written on the image is not the original exif anymore.
If i take a photo of a crime scene and used that photo as evidence in court, will the jury accept my photo as original unmodified image?
If i ribbon, by a long shot, will SC accept my original as unmodified?
Although in my hometown it's more likely that i would take a photo of a crime scene than i would take a photo that would ribbon here.
So, anyone here have had their camera hot pixel mapped? How did it go with the validation? |
