Crystal ball Photography, ie recordings of and through crystal balls, currently a trend in various photo communities appears to be who has infected me. It is clear that a glass ball for photographic purposes special visual requirements subject. For optically pure balls you can in relevant providers spend a small fortune, especially in larger diameters. I found the range of Yeti Gold therefore priced very interesting. Even decorative balls in comparable size can be bought elsewhere more expensive, but if homogeneity of the material and sanding should vote, 9 euros would be a real bargain. So I have surely ordered the 8cm ball both in quality as well as the photographers regular counterpart (5 euros). The delivery by Kathleen salt crystal charging was carried out quickly and smoothly and in optimal packaging. The package had been in transit a decent dent, but the balls were resting safe and sound between Styrofoam peanuts. I suppose the difference between the two types of production is not only the use of a machine vs. manual pulp refiner, I suspect that the blanks are specially selected for the quality photographers. At any rate, the machine ground ball several inclusions of tiny bubbles that look quite interesting for a Dekokugel for photographers with high demands but already are somewhat problematic. Who the ball photography just want to try it, without too much money to invest, and is willing to accept (hardly noticeable) shortcomings in purchase, may also reassured access to this sphere. The hand ground ball, however, is my feeling after optically absolutely spotless, no inclusions, no streaks on the inside, no slip error value a wonderful work of art and the price per se all! Moreover, the 8cm ball is very comfortable to hold, but provides with its approximately 670 grams no great burden on the daypack is, if you want to take them in addition to the camera on field trips. Larger so a photographer ball for normal purposes is not necessarily.
Unconditional purchase recommendation!
PS As already mentioned, when shooting under direct sunlight fire hazard. The ball should also be securely stored during the recording, so that they can not fall, for example, by a wall and hurt people. In the simplest case a rubber seal (Plumbing Fixtures) inferior to the appropriate size, then the ball can not roll away, and the (mostly black) rubber ring falls on photos hardly noticeable.
