K10 with 950nm IR Filter.. can't work?

[epileatheral]

I just bought a 950nm IR Filter to try out on my K10. I put it on and tried some shooting. But no matter how long I set my shutter, I get nothing but darkness. My apperture is 6.3 on my Kit lens, and ISO is 200. I expose it for almost 5 mins.

Is there anything wrong? Hope someone can enlighten me.

when did you shoot? daytime or nighttime

950nm cuts out a lot of light, couple that to the fact that k10d before mod is very insensitive to IR, 5 minutes is nothing.

I shot in the evening.. it was rather dark. So, I have to shoot in a SUPER BRIGHT day to get something? Wow! 5 mins is nothing? OMG... I probably have to crank up my ISO then.

you need sunlight to get IR.. evening IR is next to impossible when your camera is not sensitive la.

i remember playing with some of the pentaxians' k10d for IR, something like iso100 or something... with f/4 and 2 minutes? in bright sunlight. that's with 720nm too (hoya r72)... i have never used a 950nm before, but you will expect to get monochrome images.. and i think you're in for a long wait.

can ask istDS or creampuff... i think it was one of theirs.

one of the tests i learnt was to aim the remote of ur tv at the cam and press e buttons a few times..
if it can register means got hope.

 

[epileatheral]

AH! okay! I try that now!

 

[epileatheral]

Ah.. I do get some registers of red dots!

k10d definitely can take ir

but is VERY LONG EXPOSURE

 

[epileatheral]

Yeah.. VERY VERY long exposure. Any idea how long is that long? 15mins? Or even more? Will it fry the sensor?

i won't know.

why don't you get a weaker ir filter to try, it should give ok results.

definitely not 15 minutes la. just wait for better light. like right now, will not be good.

 

[epileatheral]

Not 15 mins means.. even more or less? Yeah.. guess I'll have to get a much weaker one.
