Just received my Hoya R72 infrared filter for use with my D40 and 18-55mm kit lens.

This is my first attempt at infrared photography, and the D40 seems to do it well!

Pretty cool. I didn't know you could do IR with the D40 without removing some sort of internal IR filter.

I assume your using a tripod, but how do you calculate the extended exposure time? (Or is it just "click 'n chimp"?)

Very cool!

Nikonino that's cool honestly i should say its almost two months that am strugling to get a custom IR white balance btw i have the same set up.
nikonino 13 years ago
Niikon... don't bother with the preset WB. Set the WB to incandescent +3, use M mode with shutter at about 1" and aperture +- f9.

The D40 does not need a conversion, just the Hoya IR72 filter. The D40 even auto focuses properly with the filter on the 18-55mm!

Use a tripod, compose the picture without the filter, then carefully screw it on and take the photo

You will get a red photo, which you post process in Photoshop to obtain one similar to mine. (Lots of photoshop workflows for IR on google)

It really isn't that difficult to do, just try it!

Awesome. I have to try this.

Awesome. I have to try this.

Agreed. I also really want to do film IR. Obviously this will immediately enable me to produce images just like Minor White's IR work. : )

Funny. I had decided to dismiss digital IR and wait until I had someting suitable for film. And, of course, it's Minor White that's mostly responsible for me wanting IR too :p

That is really neat, I like it a lot. I'm completely naive regarding IR, but those settings you gave, are they only good for a specifc time of day?
nikonino Posted 13 years ago. Edited by nikonino (member) 13 years ago
Settings are for a bright sunny day. The ideal time for IR photography is from 10am to 2 pm (here in sunny South Africa).

Just go slower shutter (2-3 sec) if its too dark, but rather choose a bright day

Actually, the digital sensors are highly sensitive to IR light, and the manufacturers had to build in an IR block filter. The long exposures with the R72 filter allow a tiny bit to trickle in to get IR, but it's tough because everything gets cotton candy looking unless it's a perfectly still day and can't really get people shots, etc.. The super trick way (but expensive) is to have the filter removed and convert your camera to IR only, then you can shoot full speed!

High speed IR!
I'll have to consider it as one possible use for my D40x when I upgrade...

This guy:

does some interesting stuff with IR-converted bodies and IR flash, which seems really cool.

Nikonino my problem is noise.In photoshop I did auto levels>channel mixer>adjusting hue and saturation.when adjusting hue I get a lot of noise like this and i thought D40 is not good for IR.

D50 with custom white balance on green grass and R72 worked for me but the D50 was on a temperory loan

I love my R72. I haven't been able to fiddle with it much lately, though.

Nikonino I looked at the exif of the Botanical Gardens image ,It says White balance is manual.Can u give more input on your post processing?
David Van Chu 13 years ago
kukkurovaca I'm inspired. :P.
Niikon 13 years ago
I figured it out...we have to look at the light source in the exif eventhough the white balance says manual.
White Balance: Manual
Light Source: Tungsten (incandescent light)

Just when I thought the old 18-55 kit lens was going to be shelf filler, I read that it's perfect with an R72 filter, and at only 52mm the filters are under $35 or $40! The larger ones like 77mm are ruinous, and get bad hot spots.

I say go for it!

studio_juan 13 years ago
how much is one anyway?
DPoem 13 years ago
Yep. I use mine on my 18-55mm (in fact, now it's pretty much on there constantly). It's found new life, and with the Hoya R72 filter, the camera can still autofocus.

As for composition, the trick that works for me is to keep one eye open in the view finder, and the other eye open as well and look for the little red box. Works perfectly.

Anyway, I think I paid like $30 for mine, but I'm not sure. I know the price for the 52mm threads is really good.

i promised not to make a Christmas list but looks like this one's gonna break it ^_^v
nikonino 13 years ago
Niikon...... use noise reduction software like Noise Ninja or DFine BEFORE you do auto levels and channel swapping in Photoshop.
This will produce a much better final photo that has very low noise...

@whatadqr: "The larger ones like 77mm are ruinous, and get bad hot spots."

Sorry, IR noob. Could you, or anyone, please explain?

Another infrared photo taken with the D40 and the Hoya R72 filter.
I now have the work flow for the conversions in Photoshop to my liking.....YAY!!

brown trousers [deleted] Posted 13 years ago. Edited by brown trousers (member) 13 years ago

The 77mm R72 filters are like $250 and up, and on many lenses with a front element that large, get bad hot spots where areas let a bit more IR in and burn out the photo. Considering that is more than many lenses cost and the performance is shady, I'd say stick with a 52mm R72 for under $40 on the 18-55 kit lens (which will even autofocus with the filter on it).

Nikonino please post your work flow ,if possible with screen shots

You can have the IR filter removed and you'll still be able to take normally pics you just need to remember to get a IR blocking filter to go on your lens.
kukkurovaca 13 years ago
My R72 arrived! Awesome.

I resisted the urge to out and shoot a bunch with it, because my neighborhood isn't always safe these days, and while I don't let that stop me from shooting, I'd rather not be futzing with my tripod and lens and trying to figure out how to do this IR stuff, because I'm pretty sure that would just about destroy my situational awareness.

However, I did do a quick test shot out my window using my 105mm f/2.5 K:

D40 looks to be good for IR, but what about D40x? Any experience?

Some beautiful shots here.

If you want to check your cameras ir sensitivity then point something like a tv remote at the lens press the shutter and take a test shot . . . . . . . if you have live view just point the remote at the lens press a button and look at the lcd screen ........

Thanks for the tips, nikonino. I followed your instructions, but had to extend the exposure time (it was getting late in the afternoon). Here's the result.

First test of infrared.

This is going to be fun. :)

If I buy the Infra Red filter for my d60 + 18-55 lens will I need to make and mods to the lens or body for this to work?
natures_mathematics 12 years ago
Nope, exactly the same as the D40 - see above details.

Wow! That infrared stuff looks so cool!! And - hey - me with a D40 and 18-55 kit lens, too! Looks like I'm going have to get one!

@ Clarky Snap - that's interesting. Just tried it, and it works!! But what exactly does it prove? You write that you can test the ir sensitivity. So are there different degrees of red or brightness, or...?

[edit] - another question: Just checking Amazon: Hoya or Opteka? Opteka is much more it worth the extra price?

Best of luck to you, suzysdada. It's been a lot of fun so far.

The D40 does do well with IR. ISO 200 manual F10 with 2.5 shutter speed seems to the be the best for partly cloudy sky landscapes. Full sun I go with slightly faster shutter speed.
This is my first attempt at IR taken in February of this year. Taking IR photos over water can be difficult in post editing because the water reflects the blue sky and you get weird high lights. Most of my other IR photos haven't made it to be processed yet.

Part of the reason the D40 & D40x do so well with IR photography is that they have CCD sensors that are more sensitive to IR than CMOS sensors.
