The images are mostly 768
by 1024 pixels in size, numbers in front of the picture descriptions are serial numbers of the original
photo files. Luka and Diana Avsec, Tit Sterle and Neža Košir participated in the excursion to Križna jama.
After the excursion, Alojz and Andreja Troha provided the author with all he needed to stay out of trouble
following his unfortunate fall into the water.
The names of cave parts are sometimes the author's.
The purpose of the excursion to Križna jama was to test the Huawei Pura 80 Ultra phone (photos
from PJ56202 onwards) in a cave environment. The cave photos were taken in "Night" mode, where the camera
takes about 15 photos with an exposure time of 1/10 second in a 2- to 30-second capture time, which the
camera software combines into one file, for the best result, both in terms of the balance of dark and
light areas as well as in terms of colors and moving parts in the images - for
example, of people who cannot be completely still for so many seconds.
On this his occasion, the new light gray canvas caving suit with a helmet cover was also tested for the
first time, and according to the author, it blends better with the scenes from Križna jama than the
previous dark, gray-green one.

56215. Luka, Diana, Neža and Tit in a boat on the Second Lake, facing east, towards the Third Lake. The lighting was suggested by Luka: two waterproof lamps, such as are normally used for headlamps, in the water, one held by him, the other by Tit, and the helmet lamps, set to the lowest intensity. It obviously worked well. Capture time 3 seconds, f 1.6, ISO 12800. Two clicks on the image show it in full resolution. The brightness of the published image is increased by 50% and the contrast by 33%.

56225. Flowstone buds in the stream bed below the spillway. Capture time 2 seconds, f 2.4, ISO 400.
