The sensor in your DSLR is much more powerful than you may realise, and capable of capturing photos on wavelengths that your eyes can't see. With a little work and some easily-available parts, you can tweak your camera to take beautiful, cinematic landscapes that include both visible light and near-infrared wavelengths.
ExtremeTech's David Cardinal explains how he hacked his Nikon D7000 to take shots not just in the visible spectrum that we all see, but to capture near-infared light as well. Why bother? He explains it this way:
The so-called "near infrared" spectrum - from about 700 nanometers (the longest wavelength red we can see with our eyes) to around 1000 nm (the longest wavelength to which our camera sensors are typically sensitive) - is chock full of interesting visuals. Dreary grey skies turn into cinema-worthy masterpieces, drab foliage pops and separates itself from surrounding rocks and buildings, and everyday objects can take on an otherworldly quality.
You can see an example of this in the image above, and more at the link below. Cardinal explains that you can actually have the work done for you by a professional for between $200 to $450, but if you're willing to do it yourself, you can buy the appropriate filters for around $US1-200. He also warns that you shouldn't go the DIY route just to save money -- you have to really be into the project. After all, the process does risk damaging your camera, as you have to take the housing apart, remove the original filter from the sensor, and clean everything up nicely for good, clear photos.
Even so, if you're a photography buff looking for a great project, or you upgraded your DSLR and you're looking for something cool to do with an old or secondhand model, this project might be for you. The photos really are worth the effort. Hit the link below for a full walkthrough.
