Esperite is one of the most difficult minerals to photograph. The bright yellow of Esperite is very close to the bright green fluorescence of Willemite. The two together general blow out the exposure on most every camera. Most of the time, the esperite tends to look white with a little bit of yellow and possibly have an overall green cast over the specimen.
This video shows one method to help fix this problem. This was taken with just an Applie iPad’s camera. But the demonstration shows use of a magenta camera filter placed in front of the camera sensor. You can see the comparison between the image you get with this color compensating filter and without. No Photoshop, Lightroom or Premiere was used in creating this video. This is just as the camera saw it with no post production work whatsoever.
