Hermetospheres can have a high aesthetic value. If that is part of the motivation behind them, one is tempted to capture the beauty photographically. However, objects behind glass are difficult to photograph.
Depending on the optical quality of the glass from which the container is made, the object will appear more or less blurred. My standard 5-litre jar is made of cheap soda-lime glass of varying quality. In some places there is hardly any distortion, in others very strong distortion.
In the example shown above, the glass is faulty precisely where the orchid’s flower is at its most beautiful. For an unblurred, close-up image, the only option was to open the lid and photograph through the opening from above (see below). The macro lens of 90mm makes it possible to capture the 15mm flower well, even at a distance of approx. 25cm from the object.
Photographing through the opening of the container has another advantage: you can illuminate the container from the outside without having to worry about annoying reflections.
