Greetings...
I stumbled across THIS while surfing DeviantArt yesterday. Anyone who is using Photoshop should take a look at this and give it a try. Let me know how it works...

John, I know that Fred Miranda is selling an action for that with differents settings on the internet .. I wanted to buy it and try it but did not have time yet.

I've been very curious about IR, and whether it's something I can even try on my Powershot S30... so this struck me as interesting.
I downloaded the action, and gave it a try. It seems like it didn't do much more than turn it b&w... but I'll let you decide. This is a shot of Amber Brkich from Survivor II: The Australian Outback (I'll use any excuse I can to let people know that I know her :)
Amber (normal)
Amber (fake IR)
I'll have to try this some more...

hmmm... not quite what i expected... My IR filter that I ordered is on backorder... :( I dunno when it will be here, but when it does, I hope to spend a lot of time playing with it. I have a list of things I wanna photograph with that filter when it arrives...

Here's another one, which looks a little more IR-ish...
Lake - normal
Lake - fake IR |

It's interesting though because MANYK from DeviantArt said that he got the same results as the Miranda action. He even used the images from miranda's site to build his action and duplicate the process...

| John, do you have an image you'd like me to run the action through? Maybe these shots just don't lend themselves well enough to IR conversion...? Send something along to me at alan@thefreeds.com, and I'll be glad to post the before & after if you want to experiment. |

I don't have anything handy... I would have to look thru my stuff when I get home and see what would lend itself well to IR...

I dont understand what IR is actually meant to do.
Also, as a side note, MANYK rules :D

I don't know the technical detail, but here is what I know... an Infrared filter blocks all the incoming light below or above the frequency range of light considered "infrared". These filters are quite dark, and often times, you will need a tripod to make these shots since longer exposures are required....
Check out InfraredDreams for some nice examples....

It does give the typical colours you see through an IR
filter, but obviously you won't get pictures that look the same -
IR shots look so unearthly because they are showing the hotter parts
of the image as lighter - you can't tell that from a normal wavelenth
shot, so you can't convert to get the same effect, just a similar
sort of colour scheme. |

The action does a good job for all that it purports to do. The guy who made the action fully admits it doesn't actually replicate IR photography, it only simulates it.
Quick easy course -- IR photography deals with those wavelengths of light we can't see. (Think of something along the lines of X-Rays -- not a perfect analogy, but good enough.) Therefore, when actually creating a real IR shot, you're using light waves that aren't visible. So, in color photography, those wavelengths get translated into funky colors. In B&W you get unusual shades of gray.
The action, on the other hand, modifies wavelengths we CAN see to create an effect similar to IR shots. So, instead of catching that "color" beyond violet on a rainbow (as IR film does) it modifies the greens in the shot and blows them out.
(As long as I'm basically correct, please don't get scientific on me and tell me that we're actually catching the colors before red on a rainbow, or whatever -- this was only supposed to be a VERY simplistic discussion. IF however, I'm flat out wrong about something, please do correct that.)

Patella: Very good explanation -- other than the above red vs below violet you're spot-on.

I posted some IR images a short time back - some of them can be seen here.
These were shot with a Hoya R72 filter which stands for Red 720nm - basically means it blocks all light below 720nm which I beleive is just outside the range visible to humans. This is the cheapest IR filter I could find but there are others that block much higher in the spectrum and cost much more too. It is basically just a VERY deep red filter and if placed close to the eye you can still see a very faint image through it.
Exposure times on these images were all between two and four seconds at F2.8. Unfortunately my camera is not the best for Digital IR - the lens configuration generates a very distict hotspot in the centre of the image. Keeping the lens open and not using zoom helps to keep it to a minimum but most images are unusable without a lot of post processing. Talking of which I was planning to ask the photoshop guru's on here of the best way to process out these spots out - will post again later on that note. |
