Experimenting with a 18 year old IR converted Sony DSC-R1 camera.

Removing the IR blocking filter took less than 15 minutes. If it turned out good, then I got something to play with. If not, nothing really lost.

The original would have looked something like this,

obviously taken with a different camera.

Wow! It turned out good for sure. Excellent image. So, does this make it a full spectrum camera that can also image UV light? Looking forward to seeing more.

I did the same with another (ancient) Sony camera (DSC-W15) once. Disassembly, taking out the IR filter and reassambling took about half an hour after which the camera continued to function within normal parameters though with an altered color response as expected. The (color)results its produced resembled your result (for as far as I can tell from your one sample).

WOW! Your effort is well worth.

Does it focus out to infinity? I did this with a Nikon Coolpix 950 years ago, and replaced the IR blocking filter with clear glass to maintain the optical path. This allowed the camera to focus like normal.

Not sure to which post you reply so I'll answer anyway: the Sony DSC-W15 focussed the same without the IR filter as it did with the IR filter despite not replacing the filter with clear glass like you (obviously) had to.

As far as the focusing goes with the converted Sony DSC-R1, I’m not happy. Most images are blurry, either near or far. And I used a tripod. This may have something to do with the cheap IR pass filter I used. Likely will restore the camera to its original form.

Thanks for the interest.

If the camera is recording full spectrum the images usually aren't sharp. Lenses have focus shift over the vast range. With the right filters the range can be reduced to UV, visible, or IR. Then the images should be sharper.
Still fun to experiment.
