My last Nikon D70S whach had been converted for IR finally bit the dust. So I replaced it with a cheap D3200 with a full spectrum conversion. This means I can use various filter to get different effects. This was a manual 5 pic pano, with an IR 720nm filter. Still haven’t managed to get my custom white balance set quite right, but it’s a start.
Superb Darren
Cheers, John.
I’m limited to lenses at the moment as the camera uses AFS lenses and older. I only have three of them, and only one has filters for it yet. Aim to get another couple for the 10-24mm but I’m not sure if such a wide lens will introduce hot spots. The cheaper lenses seem to cope better with this, and of course the focus shift with IR and UV. For now I am limited to a Nikkor 35mm, which is what produced this shot
For lenses have a look at mpb, I have bought most of mine from there and all of them have been in excellent condition.
I used to do a bit of IR photography back in my film days, but I’ve never tried it since.
That’s exactly where I got the 10-24 from
A lot easier now with digital, no more tripod required for most shots. Taking the ir filter out gives an extra 2 or 3 stops. I considered just having the original filter replaced with a 720nm, but then thats all it can be used for. This way allows the camera to see full spectrum, and with the right filter on the lens I can also shoot plain colour. The other one I have at the moment is the 850nm, totally devoid of colour abd should be good for pure black and white
Hi Daz
If you want to take the guesswork out of whether lenses are suitable for IR (ie minimising hot spots), there are a couple of databases out there that have tested and rated most of them
Eg - this one from Kolari vision -Lens Hotspot Database – Kolari Vision
For custom white balance, try this from Rob Shea - free download of custom white balance profiles for most cameras -Infrared Profile Pack | Rob Shea Photography
Ive used both for my own IR set up (a Sony A6000 and most recently a Nikon Z6 - both converted to 720nm as i only really do black and white for IR)
Hope that helps
Andy
Cheers for the links, I had seen the Kolari Vision one before but had forgotten about it!!! I’ll also have a look at the white balance link. Ive been using the grass, but with the dry weather we’ve had, I’ve been struggling to find some that is actually green!!!
If it’s pure black and white you should have a look at the 850nm
If you load Rob Shea’s dng profiles in Lightroom and adjust the white balance for maximum overlap of the RGB channels (when the white bit is largest) you get a decent white balance for processing RAW files.
Good news on the lens then
The reason i went for a perm 720nm conversion over 850 is that it offers a better wavelength compromise between contrast and exposure for B & W, and with 850nm, you lose a couple of stops of exposure plus lens hot spots are worse
If youre setting a custom white balance “in camera” each time you shoot, i’m guessing you must be shooting in jpeg? If you shoot in RAW, you can just use the Rob Shea profiles in Lightroom and sort it out in post rather than in the field (as it were) - much easier
I’ve pasted a couple of shots below from a recent trip to NYC - shot in RAW using white balance in camera, then processed in Lightroom using the Rob Shea profile for my Sony A6000 (Ive only had the Z6 conversion a week so still playing around with that, but the LR profile for that camera look pretty spot on to me - shot the church shot below with it)
