Easy IR (Infrared); Create Your Own From Any Color Image File Page 2
Choose Edit>Fade Gaussian Blur, #6 (Filter>Fade in Photoshop 5). Click the Preview box and change the Mode of the blurred channel to Screen or Overlay. This is the blend mode which controls how each layer will interact or blend with the layers below it. Since the default blend mode is Normal, this is what you should first see in the Mode window in the Fade dialog box. Click on the double arrows and then select "Screen" or another mode from the Mode pop-up menu. You'll probably want to re-adjust the Opacity slider according to the mode setting you've chosen. Try Screen first, then Overlay. Sometimes, Overlay provides better contrast and richer blacks, but may make the image too dark. Again, you have to experiment. Try other mode settings, too, like Hard Light or Soft Light.
While you're still in the
Fade dialog box, drag the Opacity slider to the left to reduce the effect of
the blur. The amount varies with each image and with the amount of blur you
applied originally, so try a number of different settings. In some images, 5-25
percent works well, in others, 80 percent. In the example shown here, I found
that a fade to 30 percent worked well with the Screen blend mode, #7. But I
also liked the look with it cranked up to 60 percent, although a lot of detail
was blown out at this higher setting. Again, you can fine-tune the tonalities
and contrast with a Curves or Levels Adjustment Layer.
(Remember at the outset I suggested that you make several copies of your original. Now is when you might want to haul some of those out and repeat the earlier steps trying totally different Gaussian Blur, Mode, and Opacity settings.)
4) IR film exhibits
pronounced, gritty grain, all part of the IR aesthetic. If you want to add a
grain effect to your digital IR image, make a duplicate of your Background Layer
by choosing Layer>Duplicate Layer. Now, with the Duplicate Layer active (highlighted
in the Layers palette), choose Filter>Noise>Add Noise. The Distribution-Gaussian
setting usually works best while the Amount varies according to the size of
your image. Play with the slider until you see the look you like. Be sure to
check the Monochromatic box at the bottom. When this is on, noise is applied
the same to all color channels. When off, the effect is random for each channel
and can introduce unwanted color in your monochromatic image. As with the Gaussian
Blur, you can experiment with different blend modes for this grain layer. Try
Edit>Fade Noise and try different blend modes such as Multiply and Darken.
If the image with added grain is too low in contrast or too dark, flatten the image and apply Levels or Curves to adjust the tonality and contrast if you're working with Elements 2. With Photoshop CS, add a Curves or Levels Adjustment Layer and group it with the background copy. Then in CS, to compare the last IR effect to the one with grain, simply go to the Layers palette and click the eye icon for the noise (grain) layer on and off. You may prefer not to add grain for some subjects. I tried it with this example and decided that I preferred the smooth sculptural skin tone without grain.
5) Yet another filter to experiment with that enhances the IR effect is Filter>Distort>Diffuse Glow. You can try it instead of Gaussian Blur as described earlier. Or add it after you've applied a Gaussian Blur.
Finally, for the richest results from a desktop ink jet printer, keep your file in the RGB color mode and print in your printer's color mode. Your print will still be black and white, but you'll be using all the inks instead of just black for a smoother, deeper print. For striking black and white portraits such as this, I prefer to print on a heavy art paper such as Luminos Classic Velour. A matte or slightly textured paper enhances the fine art feel of IR imagery.
These operations take much longer to describe than to actually perform. So open up one of your favorite color portraits and take it in to the eerie and dramatic world of IR.
