Visibility IV / V
A tile play with a crystal sample photographed on the bank of the Kemijoki River with a fairer negative lamp.
Image 1 is a stack of 6 images from the same time (20: 18-20: 22) as the crystal images.
Image 2 is a single 30-second exposure of the best stage of the play a little later (20:40).
The remaining images of the crystal sample collected at 20:16 to 20:25. Admittedly, in dense crystal clouds, crystals still appear on the glass as they are photographed. Again, the last crystal image was taken at 20:46.
Figure 3. is a normal crystal image of the sample.
Figures 4-5. are cross-view stereo images of the crystal sample.
Figures 6-7. are anaglyphic images of the crystal sample, i.e., these require red-blue glasses (red-cyan glass). Figures 5 and 6 are from the same image. The latter only shows a wider area of the image.
