Hi all,
 
I was wondering if it's really necessary to use filters at all: I can't
believe it's not possible to start from a color image in Photoshop and
simulate infrared in the B&W conversion - lighten green, darken blue...
Shouldn't be so hard...

In my experience with Kodak and Konica infrared films, evergreen trees emit
much less infrared radiation than deciduous trees. They might be a bit
brighter than on regular BW film, but not white like your leaf droppers.

But then I usually use an orange filter, as I don't go for an intense
effect, and that's with film, so YMMV.

I've messed with it a bit, using color negatives shoot without filtration.
Some images gave good results, some not.

One problem is that by darkening the blue channel (I pull it way back in
channel mixer, and pump up the red channel, add a dash of green and pull
back on the constant slider) it seems to really accentuate whatever noise is
in the blue channel, which in the case of my scanner is considerable. It
also gives a strange variance in grain across the image - much more in the
sky than in the rest of the image for instance.

So, sometimes tonally you could get the effect, sometimes not, but even when
you could the grain/noise issue was weird.

Again, just my results with my equipment.

There are plugins for IR--they don't seem to have the true IR look though for most people.

You can get close by using mostly red in the channel mixer, but infrared has
quite a different luminescence than colour film. Foliage is rendered much
lighter, and skin tones have an almost transparent quality.

There is a lot of info on creating IR from colour in photoshop but a 
lot of the hassle may be reduced by using a digicam. Take a look at 
Eric Cheng´s site:

I tried it, it doesn't work. If you know a way, let us know!  That would
even be better than a filter, if it works. But I don't know how you'd
get the greens to go nearly white and still look right.

Jerry,
I think you own a pretty good source for counterfeiting IR with 
Photoshop. Martin Evening explains his technique in *Adobe Photoshop 
6.0 for Photographers*: "Black and White Effects", pp342-343. Looks 
like IR film, though, with its lovely, indistinct quality rather than 
the equally wonderful pin-sharpness of digital IR.

Bob, just a note.  I had tried a simulation of HIE IR film in several of my IRs with information from someone who shoots both digital and film.  I would have to find the URL again.   The ones I did have a much different look from my 'normal' digital IR's. 

I just looked at the pages you suggested---interesting--I guess I glossed over that at some point LOL.  I'll just have to try it for fun.

It's quite hard work, as the infrared response from different shades of the 
same colour can be quiite different depending upon what it is doing the 
reflecting.

Re: [Digital BW] Infrared (was: Shooting Digitally)

2002-01-22 by Derek Clarke

I think you can simulate EIR as follows.

1) Take one IR picture and one full-colour picture of the same subject in 
exactly the same position and lens focal length. Obviously this is a tripod 
job and moving subjects aren't possible :-)

2) Convert the IR to greyscale if your camera doesn't already render it as 
perfectly grey.

3) Split the colour picture into red blue and green channels.

4) create a new picture with the IR as the red channel, the colour's green 
channel as the new picture's blue channel, and the colour's red channel as 
the new picture's green channel.

This simulates the response of EIR with a yellow filter on the lens.

Re: defining custom paper size in 1160 driver

2002-01-23 by Peter McLennan

I'm printing with an 1160 and I'd like to define a custom paper size to use 
with the "user defined" choice in the "paper size" dialog in the printer 
driver. Anybody know how to do this?

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
