Did you know that infrared light
Distant vistas, almost invisible in the haze,
Become clear with infrared

Haze reduction through infrared
What a difference!
Dark areas near IR center are cloud shadows – (at the bottom right in the enlarged view)
Shenandoah Valley from Skyline Drive, Shenandoah NP
Top image – Nikon E5700 P&S
Bottom image – 35 seconds later
Same camera but screw-in IR filter added
The screw-in IR filter is opaque (can’t see a thing through it)
I took the top image without it
then, screwed it in and made the lower image
Shutter speed – 1/831 without, 1.40 with
Over 1000x longer (2000x since ISO was doubled)
This is how I started in IR
An old P&S with a screw-in IR filter
Highly recommended as a great way to learn
The cons of this approach are
Opaque filter requires framing shot before attaching filter
Opaque filter requires shutter speeds longer than a second
Both of the above necessitate a tripod
But there is a big pro –
If you shoot the color version before doing the IR
You have both a color and an IR
That allows for all sorts of color & selective color fun
By layering the two versions
In the case of this image how about making a color version
With the detailed distance of the IR version
By layering & blending in PS
(Could be done better; didn’t want to take the time)
Top – IR + Color Blend in Photoshop
Bottom – Color as captured
Or – you can layer the IR above the color & erase portions of the IR to get selective color effects like this –
