Has anyone converted a D3 for IR ?

Yes, has been done but it's problematic, the D3 and most of the newer bodies have a little IR lamp and sensor either side of the shutter which monitor the shutter speed and automatically make corrections 'on the fly'. Unfortunately the IR lamp causes fogging of the image on a converted camera; masking the lamp triggers errors. There are workarounds but I seem to remember they involve altering the firmware. o.O

Will PM you...

I have to say that is a waste of D3.

I agree but I have a spare D700 that would convert nicely.


The D200 is perfectly acceptable as most subjects have sunlight so don't need high ISO.

Does the D300 have this IR light thingie?

I always saw that as a potential upgrade from the D200.


Recognising with IR, that you don't ever get the same degree of sharpness, using the best cameras and lenses might be overkill.

I agree a D300 would be a good option but my D300 is now dedicated to my underwater housing.

 Apparently according to LifePixel website.

Nikon D40, D60, D90, D300, D300s, D3000, D5000, D7000 are not great for IR as they have problems with setting a decent WB Preset when used in IR.

The D3 series, D4 and D700 models make use of Nikon's new infrared self-diagnostic shutter monitor circuitry. This function involves an internal infrared LED emitter/detector chip that could fog images. In most cases it will not be an issue unless you shoot in overcast weather using higher ISO and/or longer exposures.

The D90, D300, D300s, D3000, D5000, D7000, D600, D610, D800 and D800E these models are random, some will white balance all filters but some not at all but most just won't white balance with our Super Color & Enhanced filters. Will need to shoot in RAW and use Nikon Capture NX2 software to set the white balance.


So that leaves as good cameras for conversion the D1, D1X, D70, D70S, D80, D100, D200 and D2x.



Then of course there is the Fuji Xpro1, XE1, X100 that shoot IR (unconverted) but with a R72 filter on the lens very nicely but you need a tripod to use this as exposures are typically 2-4secs with ISO 400 at f5.6-f8.  It is easy to pre-visualise the IR result with the TFT screen.

I don't do a preset for the WB anymore ....even with the D200.

I shoot raw and adjust the yellow-blue to c. -80. ( i think ...without checking) This was the setting I always got from my precalibrated D70 whenever I opened its raws.

So I wouldn't discount these models.

I don't however like the idea of the IR fogging with the newer models you mention. One of the complications with IR is getting the right exposure in shaded or overcast situations. The meter increases the exposure based on the visible light without regard to the IR additional exposure...result over exposure.

Yes, somebody must have been taking the pee at that moment!!! LOL Just like Flicker seem to have lost the e, when they made their website. o.O

I have been struggling to understand how to easily post images into forums from Flicker. Several people have tried to help me but I couldn't master it, so knowing Jeff (Blackfox) hosts all his stuff on Flicker I figured he must be a good chap to ask, so we spent over half an hour on the 'phone trying to figure what the problem was. Thankfully it was trivial, between us we finally sussed it when he had the same issue trying to post into this forum while we were on the 'phone. Thanks again Jeff.

Jeff realised we were using html rather than BBCode, I hadn't spotted the selections available on the Flicker screen. We got there in the end! :bowing:
