INSTITUTE OF PHOTOGRAPHIC STUDIES
We all are passionate photographers and care for our equipment with equal passion. We take care that there is no dust, no fungal growth on sensor or in the lenses. The climate plays a major role in whether our equipment will get fungus or not.
For getting crisp and sharp images, we need unobstructed light from the lens, landing straight onto a sensor. Any kind of fungus (or dust) within a lens is going to disperse light, and is going to add softness to images. Simply, less sharpness, less details, reduced colour, and of course lesser satisfaction! No one of us would want to happen this to our precious equipment and images. In simplest words fungus is a natural thing, which IS going to grow by every passing day, and if care is not taken in time, it would make it difficult for service people to clean it.
To put it in straight math -
The simplest formula to avoid or prolong fungal growth is-
Coastal areas have more humid conditions compared to interiors, where the air is dry. But it cannot be a reason for not caring for equipment.
1) A silica gel bag is an nstant remedy , but for a very short period. These small bags absorb little moisture around, and need frequent replacement or maintenance.
2) An air-
3) Another good and cost effective solution is a compartment in your cupboard or a glass (not plastic or acrylic) fish tank, fitted with a low (zero) power bulb in one corner, and all your equipment can stay in another corner. The heat emitted would ensure that there is no humidity. If you have a temperature measurement device, make sure that the temperature within the compartment is about
5 degrees C higher than the room temperature. Keep the compartment ventilated so air doesn’t get trapped within. What you can store in this? Cameras, lenses, binoculars, filters, What NOT to store here? Memory cards or similar storage devices, batteries, wires.
4) Another way of avoiding fungus is to buy an electrically operated dry cabinet which is readily available. These cabinets have temperature and humidity control. This is an off the shelf remedy and really works well. If you feel it’s expensive, (can be within Rs. 10,000/-
5) Keeping you equipment in constant use, exposing it to sunlight, is another way to keep fungus away.
If you are not going to use camera for long, make sure to take it out every alternate day and keep shooting a few pictures. Let your camera see a lot of light.
6) Camera bags can store moisture, and if bags remain in cupboards for long, they make fungal growth easier. So expose your camera bags in sunlight for 2-
It’s time to get your sensor and lenses cleaned. But from thereafter, precaution is the best remedy to avoid fungus. If the fungus is there for long time, it might have attacked or ‘rooted’ itself into the lens coatings, and even the service people may not be able to take it back to normal. These will certainly leave marks on the lens, adding some unwanted internal lens reflections, and degrading your images.
Get rid of fungus & dust, get sharper results, always!
