This image shows what we hoped to accomplish with our thermal flashlight. This imaged was created with Photoshop. Based on the bathtub photos (see Field Notes 8) and our daytime data collection, we believed we could capture colour over a broader area of the water. However, as Photograph 2 shows, the flashlight realistically shows streaks of light, rather than light diffused evenly over the surface. We believe if we had put some sort of diffuser of the lightbulb itself (and had our tech not failed), we could have achieved this result.
