The new filters with the patended shape use their little teeth on the side and "bite" inside the UV-filterīs thread. If necessary you can press or screw them in a little. For removal simply tear the little hook onto which the filter type and exposure factor is printed.
ADOX gelatine filters are made from the world famous Cibachrome(R) dyes which are light stable and will almost not fade out. The modern ADOX coating facilities in Switzerland and the coating know how of the Swiss enable us to manufacture these filters water protected so that they can be wiped with a wet cloth shortly to clean them. You can also wipe off rain drops.
