How to convert a Nikon D50 DSLR camera to Full Spectrum

  • Watch as I dismantle a Nikon D50 camera to remove the internal filter that blocks UV and Infrared light. The plan is to replace the filter with a clear filter, but it turns out to be too thick so I use the camera with no internal filter. I wanted to add the clear filter as a dust shield that would place dust particles farther away from the sensor. This would make the dust less visible in images. There is still a piece of glass from the factory covering the sensor. The reason I converted my camera was to be able to photograph faint nebula easier. The factory filter is designed for standard photography and blocks a large amount of light in the wavelengths of Hydrogen Alpha and more. Nebula such as NGC7000 North American Nebula emit this color of light. Since I am leaving it full spectrum, focus may not be as sharp because UV and Infrared focus at different points than visible light. Another issue is auto exposure is calibrated with the internal filter present. Removing it causes over exposure, so I compensate for that by using manual exposure. I look at images on the rear viewing screen of the camera and adjust the exposure settings. I further adjust them using GIMP on my computer. The images look more red without the filter, so I desaturate them in GIMP until I like the results. I have been experimenting with full spectrum and Infrared images in the daytime and plan to make a video on that.
