has anyone tryed IR photography with a D40. I cant find anything on the net about the D40 and IR.
i have tryed myself but iam struggling to get a good white balance that i can work with in PS.
the fuji i have takes great IR pics,but every pic has a hot spot in the middle. in order to get rid of the hot spot, would it help if i removed the hot mirror and replaced it with clear glass?.

regards carl.

carl yeomans,

Ask the man who uses it, I say: besides the obvious color shift, what else does infrared do that you like in a photo?

besides the obvious color shift. it can make an ordinary pic look better by Comparison. the few ppl i did show the second pic of hemlington lake said, wow they didnt recognize it.

anyway i like IR,and thats all that matters really.
horses for corses.

Carl-

I really like how these turned out. Would you mind describing your process / gear a little bit more? I'd really be interested in finding out what kind of filter / settings you used and even a bit about how you process them :)

sure nicole, ill try.
the filter i used was a hoya r72.
kit lens 18-55.
a tripod

exif
aperture f/4.2
shutter 1/6
iso 200
white/B manual
focal length 30mm
format RAW

set costom WB to green grass with IR filter on. if your camera wont allow you to do that, use incandesant +3

take the raw file to photoshop raw converter. i set the temp to 2850 and the tint to -27. then in photoshop i just run my own( false colour IR action). ajust the levels and curves. do anyother hue&sat and desaturate the colors i dont want.
like in this pic the only thing that has colour is the sky and water

Great, thanks for that Carl. I love IR pictures, and eventually I'd like to try some for myself, so consider it information gathering :) I always heard that IR needed long exposures, so I was curious how long it would be in this case. Now, to find an IR filter in my budget :p

Great shots Carl.

I too have a D40, Hoya, and I shoot some IR every so often. Mine don't look as nice as yours though.

You can see my IR feed here (http://beta.zooomr.com/smartsets/trevorcarpenter/11257).

I have been stuggling with my Rebel XTi and infrared. I have the Hoya 72. I have only attempted it a few times. I keep forgeting to take a color picture as well in the same spot to use as an overlay. I should try some more perhaps today if I feel lucky.

The more IR-pictures I see the more I want to get a filter myself, waah, I have to. And that third picture of yours, carl yeomans, is absolutely gorgeous, love at first sight :D !

I love the look of IR as well, so I blew my tax refund this year on getting a point & shoot converted to IR by an outfit called lifepixel.com. The camera is permanently set to shoot in IR - their site explains it better than I can! The advantage is you get nice fast exposures and you can see the real image on the LCD screen for composing and exposing. No tripod necessary. I've just recently gotten it back and am still getting the hang of it and haven't taken it out on any trips yet. We don't get many dramatic skies in San Diego at this time of year so I'm still waiting to get a great sky shot like your lake photos!

Here are the ones I've taken so far...

Hi Carl,
I am new to this topic. I always failed to preset the WB on green grass. Sunshine is abundant where I am at. I tried numerous settings, changing exposures and yet it always failed. My filter is Hoya R72, using D40 and the kit lens. what was the exposure you used for presetting the WB?

Any reply would be helpful

Cheers

Johan

There's another tecnique without filters that produces an IR effect.

In photoshop, open image, then open curves and put in the following values.

R-160

G=140

B= -200

Pretty cool, huh?

Regarding the white balance, if you shoot RAW you can set if from the grass in photos afterwards anyway so it's not that crucial to remember when you're out taking photos.

It is nice to set i while you're out though because your pictures will look more finished when you view them back on the camera giving you a better idea of what you're really getting.

Carl,
I'm waiting for mi filter to arrive and start trying with your configuration, so first of all, thanks for the posting.

My question: I keep reading about modified Ir cameras. I know the concept, and i have read about it, but i want to know if the pictures you have shown are taken with a modified D40 or you just plugged the filter and started trying.

Thanks again.

Joaquin
