Starting in IR photography

[Erik Lund]

Some very nice and delicate tones Jørgen, very moody

[Jørgen Ramskov]

Thanks Erik, it fun and sometimes frustrating to fool around with. Can be difficult to find the colors that works with a specific image, but I like this result.

A couple more from Egå Engsø, taken on the same trip as the last one above.

First one stands out with the reds - Warm,,,

I feel a NikonGear IR workshop should be in the near future!

[Jørgen Ramskov]

#1 is my favorite too.

A NG IR workshop would certainly be interesting

You are triggering a serious "I wanna try" sindrome

[Jørgen Ramskov]

Have been sort of away from NG for a bit - haven't used my IR camera or my D750 much, but I got a chance to borrow a Nikon 105mm f/1.4 (what a lens!) and why not try it out on the modified D40x camera? I can't change aperture so all is shot at f/1.4, but that's what this lens is for isn't it?

The D40x cannot set the aperture on any 'E' lens. However, you can set the aperture with say your D750, press the stop-down button, and while keeping it depressed, remove the lens and put it on your D40x. Simply once you have tried it. This trick even works when the 'E' lens subsequently is mounted on an ancient F or F2

The only caveat is the new host will display '1.4' instead of the aperture you set earlier. No wonder as the non-compatible camera doesn't know how to control the aperture in the first place. But the lens remains set to whatever value you selected initially.

[Jørgen Ramskov]

Thanks for the explanation and "cheat", I'll try that this weekend 

As for the IR images, I'd like to add that I still find the PP to be a "curious" experience understood as it being fun to explore what you can end up with, editing an image. You often end in a completely different place than what you imagined.

[Øivind Tøien]

Thanks for this interesting information. I would have thought that the lens would reset, once powering down, so this is quite a surprise.
I just tried it on the 300PF. So aperture mechanism apparently has a motor that drives it in both directions, and not one that works against a spring load. It is probably wise to turn VR off before applying this technique to a VR lens.

[Bjørn Rørslett]

The 'E' lens has no mechanical means of controlling the aperture. Thus as far as the non-compatible camera is concerned, the lens hasn't an aperture at all Meaning also that the metering works, but in effect with stop-down metering.

[Øivind Tøien]

Thanks, that is another good point to keep in mind.

[Bjørn Rørslett]

Nikon has taken many steps to prevent users from doing true stop-down metering, but these measures are null and void when it comes to 'E' lenses on non-compatible cameras.

The camera only "sees" a reduced incoming light intensity and has no knowledge at what aperture this occurs. Since the camera cannot change the set aperture this is a matter of no concern.Light metering will function normally.

One might say Nikon has tricked themselves in this manner.

This insider's tip work with all 'E' lenses I have tested so far.

I have tried the 105 Nikkor-P f2,5 on my D40x the last few days and it seem like a decent performer. Little focus shift and very sharp IMO. I have used the B+W IR830 filter and the lens wide open. Like it a lot.
