Blue Filter for Top-down Porthole

16 reviews
$ 7.99

This polymer filter reduces blue light reaching the camera sensor, resulting in better photos with more natural color rendition.  The filter simply slides into the bottom of either our standard Top-down Porthole, or the XL version.  This color filter was chosen specifically to filter out Blue from LED lighting, we are currently developing another filter for fluorescent light spectrums.

*Fits all current models of Porthole.  Will fit older gray housing Portholes but will not go completely to the edge.

Don't bother with this.

I do not like it. It makes the brighter colors really dull. I ended up just turning up the white lights when taking photos instead of using this.
