really was good- printable photos + 120fps shooting. Is a shame...

+1 (if I can) for using your noodle and looking at the EXIF!

Haha, it's a force of habit, I always check data for nice pictures I come across on the internet.

Yeah the 120fps shooting is definatelly a cool feature, especially for checking out spark formation and other fast phenomena. But honestly what impressed me the most was the silky smooth 30fps 640x480 videos, on par with an old digital cam I used to own, but in a phone. :D

Though besides that the software of the phone really pissed me off. It has great hardware (ZORAN chip, made by an Isreali tech firm), but no damn software support. :gun: That's the only reason I upgraded to a Blackberry...I use the KU990 to shoot in "dangerous" (high EMF etc.) conditions. :D

Another fried camera - lasers will do that when you shine them directly into them.

It seems the damage treshold of most ccd cameras is quite comparable to that of the human eye - most manuals will also warn against taking pictures directly pointing at the sun to prevent similar damage.

Bluray is especially dangerous since its hardly visible - shine the dim dot at a fluorescent surface and get an instant lightbath to remind yourself once in a while ;)

I'm no expert on projecters but they use emitters or big LED's, since they give off light and not recept light I doubt very much if they are sensitive at all to most lasers below 100mW, just my 2 cents :tinfoil:


I have heard that lasers can also damage video projectors too- that would suck worse than the camera, but that's nothing compared to a precious retina! good pics & points

I dont see how it would damage a projector either, short of shining the laser into its output lens... but why on earth would you want to do that?

Always use care, and btw, I am testing more red goggles, and it seems that I have a pair that look identical to the ones offered by CNI, WL, & OEM Laser Systems etc. that actually allow 6.5% of BR light to pass, this is troubling as both CNI and OEM state they are 99% blocking in 405nm. I'll be trying more goggles soon to look for better protection, best to also, Always use care! -Glenn

It took me a minute to find this, but I knew I had read it somewhere- The issue is more with high powered laser projectors. What happens is this- if you have a video projector pointed towards a screen/stage, and a laser projector on the stage pointed back in the direction of the video projector (especially a DLP), stray beams from the laser projector might enter the video projector.

Warning All Laserists - Dlp Projector Damage - ILDA Forums

Professionals can use what are called "beam attenuation maps" to decrease output power in specific zones to prevent these types of accidents.

I am no pro, but I do have a 300mw 532 in my primary beam projector and a sum total of white light > 500mw, and a DLP video projector, so I took note when I read the contents of the above link.

Thanks, Mike
