What is infrared photography and how does it work?
Infrared photography is a unique and creative way to capture images using light that is invisible to the human eye. It works by using a digital camera that has been converted to capture infrared light, which is a type of electromagnetic radiation with a longer wavelength than visible light. This allows photographers to capture images that reveal details and textures that are not visible in traditional photographs.
Infrared photography can be used to create a wide range of effects, from surreal landscapes to abstract close-ups. It can also be used to capture images in low-light conditions, as infrared light is more prevalent in these situations. However, it’s worth noting that infrared photography requires a converted camera, as traditional cameras are not equipped to capture infrared light.
What kind of camera is best suited for infrared conversion?
The best camera for infrared conversion is a digital single-lens reflex (DSLR) or mirrorless camera. These cameras have interchangeable lenses and can be easily modified to capture infrared light. It’s also important to choose a camera with a full-frame sensor, as this will provide the best image quality and allow for more creative control.
When selecting a camera for infrared conversion, it’s also important to consider the camera’s age and model. Older cameras may be more suitable for conversion, as they may have fewer electronic filters that can interfere with infrared light. Additionally, some camera models may be more prone to “hot spots” or other issues that can affect image quality.
What are the different types of infrared conversions available?
There are several types of infrared conversions available, each with its own unique characteristics and effects. The most common types of conversions are 720nm, 850nm, and full-spectrum. The 720nm conversion is the most popular, as it provides a good balance between infrared and visible light. The 850nm conversion is more extreme, capturing only infrared light and producing a more surreal effect.
The full-spectrum conversion is the most versatile, as it allows the camera to capture a wide range of electromagnetic radiation, including ultraviolet and infrared light.
