p.1 #1 · D700 and IR photography


Anybody had any success with their D700 and IR photography? I am just waiting for a day off to try it with my new camera.

Give it a try and let us know. Nikon's history is to block more and more IR with each new camera. The D70 was okay. The D80 almost impossible. I haven't even tried the D90 or D700, and really have no plans to try them.

p.1 #3 · D700 and IR photography


Just happened to try this earlier today. It was overcast /rainy and I used an 830nm IR filter. To maximize exposure required ISO 1600, 30sec f4. Not really a viable option.

As already mentioned, the newer, or more expensive, the DSLR the better the ICF. I have a few transmission spectra of various ICF on my site www.beyondvisible.com/BV3a-ICF.html which will indicate the issues.

I would like to hear from anyone using an 830nm IR converted D700 as I am considering this one myself.

I had LifePixel convert my D700 to IR BW about 6 months ago. this is my 3rd IR camera. I love the IR D700. there are no problems and I get sharp, crisp IR images. you'll like it.
regards, tom

I am pretty sure I know the answer to this,but just have to check as I have never looked into this...once your camera is converted to IR is that all you can use it for?

yea, I believe they swap out the sensor and it becomes an ir cam.

What the conversion does is remove the IR blocking filter and replace it with an IR pass filter. And yes the camera is then a dedicated IR machine.. I had my old D-100 converted and it's a lot of fun. Considering getting one of my D-300's done when I purchase another FX body.

Here is a shot or two from the converted D-100..

I would recommend a basic removal of the AA filter, and just that. Use the filter in the front or rear (depending on lens) some lenses have the clips for rear lenses. You also have a wider variety of filters to choose from. They all do interesting things on the nikons.

my latest project was on an old D70. removed the AA filter, then put a sliver of exposed and developed C-41negative film at the rear of my 15-30 sigma. Made a custom WB preset. Voila. The shots below are unedited, straight out of camera:

I've never had blue skies straight out of camera with IR. I'm pretty happy with the results.

Wait, WHAT?!

So if I just got a sheet of developed C41 film, used it as a filter and made a custom WB with it, it would look like that?!

the AA filter wouldn't affect color like that though unless it doubles as the IR cut filter.

You might want to post your questions about IR conversions and suitable cameras here:

http://nikongear.com/smf/index.php?board=57.0

or refer to the archives there too:

http://nikongear.com/smf/index.php?topic=22929.0

Anyway, the best folks I know from a technical (if not aesthetic) point of view regularly post there - and they are nice, and open to anyone.

the AA filter does affect color, keep in mind, it blocks IR. So certain blacks will show up purple without it. Without a filter, you'll get a full spectrum of waves. UV/IR.

Do not lose sight of the fact that once you remove the IR filter, the camera cannot be used for "normal" photography. It is an "IR ONLY" camera.

not true. Buy a hot mirror filter, for the lens. I know really not the greatest idea, but cameras like the leica M8 have no aa filter. So they require an IR blocking filter to go on the lens. So in reality your D700 would be a full spectrum recording camera. If you throw an R72 filter on it, you'd get only IR.
