Some infrared images

[Eon]

Yeah, there's some postprocessing involved.

First I use the Gimp to get the blueish otherworldly effect, or sometimes leave the red sky if I like it better.
Then I pp some more sometimes with either SFX pro or CFX pro.

I can post a series of an image as it processes through the workflow if anyone likes.....

 

[Eon]

Yeah, I share Gary's curiosity. How much of the effect is purely filter, how much is post-processing? Are any of these images straight OOC without PP?

The house framed by trees of light is powerful.

This is a different pp of the house, but now they are really trees of light

Lonely tree in the middle of a nearby rapeseed field. Infrared.

Oooooh, nice!

Okay, apart from a very nice image of a lonely tree in the middle of a Rapeseed field ... why is your tree black (cold) and the trees in this thread white (warm/hot)? Maybe the filter's primary function is to turn green to white?

Sorry, over the edge, chlorophyll is very reflective in NIR. Your tree should have white leaves. Your sky should be black and your clouds should pop.

I don't think I get it?

Sorry for any confusion, this is just a normal .jpeg image converted using the infrared filter in Lightroom. :smile:

Hmmm, maybe I get overenthusiastic a bit too quickly...

I really like that last shot you posted at the beginning of the thread! great stuff

Somethings can't be done in post processing. The data needs to be in the original file.

I always liked the film version of IR and the electronic version seems to be equally fun. I'll try it.
Thanks,

The green emenates certain thermal heat which isn't visible to the naked eye. By using a very very dark red filter, if your digital camera does not have high pass filter like in Lumix cameras, it will block the green and capture only the thermal InfraRed coming out anything green.

Since it is a red filter, it will make anything blue darker. The basic 101 of old B&W negative film photography.

This being said, human beings also emenate that thermal heat. The skins end up becoming very dreamy like the greens in IR photography.

This is near infrared. There is no heat or thermal signature. That would be far infrared. Basically, objects and materials that appear light are more reflective in near IR. If you were seeing a thermal signature, you would be able to photograph the object in a room without light.

The sky is black because it does not scatter the longer wavelength of NIR. This really cannot be described as filtering color.

Yes I have done B&W film IR in night clubs where there were no lights. The skins of the human beings were glowing.

I would love to see the pictures. What was the source of the IR? BTW, lenses cannot focus not transmit thermal radiation, not glass ones anyhow.

 

[StudioHeraBell]

I have to scan them, and there is some nudity. I can't upload them here. They are in negatives burried in my folders. Kodak made the B&W IR negatives. They were 400 ISO, sometimes I pushed the film. Camara was Canon AE1 lens 50 mm f/2.8 All manual. I had to focus first add the filter then shoot.

I know the Kodak film. Whether film or digital, it does not record a thermal signature. It is simply reflected NIR radiation. The source of the IR was your lighting.

IR film was commonly used in flash photography to photograph in bars and nightclubs so as not to disturb the patrons. The flash unit was filtered to only allow the NIR from the flash output. Because of that, the flash was never seen.

What is the difference between the 72 and 92 filters?
