D70 goes IR - add your Infrared pictures to this thread

Go to last post
I just ordered the R72 from Adorama yesterday, and am looking forward to experimenting with IR myself. Glad to see some results from this filter with the D70, as I couldn't find any D70 pictures before I placed my order. Now I'm anticipating the delivery even more!
 
Great SHOTS!!!

C'mon SUN!!

Here are a few of mine so far (Hoya R72 52mm - can you say "vignette?")







Comments welcome!

Best regards,

Keith McKane
 
Dirk, these are gorgeous!!

A few quick questions if I may - are you using the Photoshop "red/blue channel swap" routine? if so, how do you get the whites so white? In my attempts, I'm still left with a real blue cast to everything that levels just can't solve. Any insight into some of your post-processing would be greatly appreciated by this budding IR enthusiast!!

Thanks so much for sharing your fine work!!

Best regards,

Keith McKane

Important things to get a good result are:

1. Manual WB on sunny grass through IR filter
2. Adjust tonecurve in PS (autoadjust will usually do) to get better contrasts
3a. If you want a b/w IR picture reduce saturation
3b. If you want a color IR with "blue sky" do the following
  • swap channels:
red channel: red = 0% blue = 100%
blue channel: red = 100% blue = 0%
  • optimize colours:
to remove rests of red spots in the picture reduce saturation for red and magenta to 0
to get a darker blue, darken the blue colour (lab brightness) or/and cyan

Now you should have a perfect result :-)

The bluecast may come from a poor WB or a problem with the IR Filter. Which one are you using? Maybe it is too dark to get a good colour IR?
If you could post an example I might be able to give some additional hints.

No, didn't try sofar.

But a good idea to test handheld IR. With ISO 800 the exposure time should be down to less than 1/4 sec. If you then also change the aperture you should be at a managable exposure time for handheld IR. I doubt the quality - but I will give it a try.

Sweet IR shots. How long was your exposure on these, give or take?

Exposure was about 1 to 2 seconds at aperture 8 and ISO 200.

This would hardly been possible or a lot of work. There is so called IR plugins for PS, but they do not really work. This is because the IR information is not available in the picture file. IR is range of wavelengh and represents heat emissions. How shall one replicate this in PS?

Now, if I only have landscape in a picture, this may work. It is known, that petals, grass etc reflect IR, but wood does less, and ground even less and water and blue sky does nearly not.

But what if you had a green wall and green trees in a picture? How should a filterplugin handle this?

Very nice IR pics!

Just wondering: Has anyone managed to take a normal colour pic and
then make it look like an IR pic in PhotoShop?

I really like these shots, but I just checked a few online retailers, and the price for IR filters varies tremendously. For example, at Adorama, the Hoya RM72 67mm is about $75; the same filter at 72mm (which is what I'd need) is $245!
 
You can approximate some of the drama of IR in photoshop - search the retouching forum for actions that simulate it. Here are some examples (color shots converted to an IR-like look)
