after chatting with someone else who has uses the same kit as me, he suggested that my d50 might've had a different low pass filter installed. i'm not so sure.

this shot is at f/11, 0.62seconds, with a custom white balance and then auto levels in photoshop.

is this kinda IR performence normal of the D50, or has it been modified?

my low pass filter is green looking

You can tell it's not a true IR attempt but it's a good effort nonetheless :)

and I'm pretty sure (with a R72 filter on) you would need more than 0.5s exposure to get any result as clear as that!

hmmm.. i wonder if it has been modified then. it wasn't a properly composed shot or anything, was a point and shoot test (handheld).

resizing using windows image resizer hasn't done much for the images either!!

images on this site suggest mine is standard though..

Yeah, if you had an IR filter on it you would have needed a tripod, and an exposure of atleast 15 seconds to get any image really. Like you say you just changed the levels and voila, you got the result similar to IR.

Buy an IR filter and have a crack at it :)
 
no, you've missed my point.

I have a hoya r72 IR filter. that shot was taken through it. all i did in photoshop was autolevels to bring the contrast up a touch.

that was a 0.62second exposure through a 720nm filter. I'm wondering if the low pass filter has been altered, because like you say - thats a very low exposure time for an IR shot!

Got the DUNCE hat handy? I'm going to be needing it.

Sorry about that lol, me being seriously thick.

But yes your right, can you post the original image, straight from the camera before you done any PP work please, will be interesting to see.

I know the Nikons are better than the Canon's at this work, but I didn't think it was THAT different lol.

Did you buy it second hand?

Also if the low pass filter had been altered, all your images would look off/wrong to how you see them IRL.
 
don't worry about, it is silly o'clock in the morning after all!

i did buy the camera second hand but normal photos don't look 'off' and i use auto white balance *most* of the time.

this is that shot straight off the camera

was 0.4seconds it seems, my mistake! :eek:
 
Hmm, I doubt it's modified, but I am wondering.

Was it particuarly bright when you took that? that's the only explantion I can think of?

hang on, what was your ISO?
 
was shot in aperture priority mode, so my iso would've been locked to its lowest setting - which is 200.

it was cloudy, did have some sun though. i'm not sure if ive got an exterior shots taken with the d50 without the r72 on there - but this was taken at a simiar time with my phone camera

il check on the other pc in the morning for any shots from the d50 in 'normal' mode.
 
Its just a normal D50 with R72. I keep on saying this but no one seems to be listening. The D70/D100/D50 are great infrared cameras. The D80/D40/x are not so great because Nikon have employed a new low pass filter inside of their newer range.

Older Nikons can shoot infrared photography at small F.Numbers on a reasonably crap day and can expect exposure times to be between 1 and 10 seconds.

There is nothing special about your D50. Its box standard and has not been manipulated at all.

And how long did you make your partner in crime stand there while you took that IR. Looking at the image I'd guess at about 15 secs stood stock still like that....

exposure time on the IR shot was 0.62s. The D50 seems to be very good at IR shots.

WTF??? I use a D50 and with a Hoya IR filter I'm looking at a minimum of 6-8 secs on a very sunny day.

hi. the info from that shot is f/11 and 0.62s.

all i've done to it since, is auto levels in photoshop. I always shoot IR in aperture prioirty - and use a custom white balance (normally use grass to set it).

Nah mate, that's unusual for a D50. I can only assume that the filter over the sensor has been removed by the last owner.

hence me posting this thread, to ask others with r72s and d50s!
 
it is worth bearing in mind that the original you posted is massively underexposed so to capture a proper exposure you would probably have been looking at a longer exposure.
 
I have used a Nikon D50 out in the field using my Hoya R72 filter. Some of my shots at F16 were half a second in exposure.

If he has removed his low pass filter then his normal photography would look terrible as it would have infrared radiation spoiling it.
