ADOX M77 Snap-On Infrared Gelatine Filter - Factor 2
Filter thread: 77mm
The new ADOX "SNAP-ON" gelatine filters are budget-friendly color filters to increase your creativity.
These new filters with a patented shape use their little teeth on the side and "bite" inside the UV-filter's 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 knowhow of the Swiss, enabled ADOX to manufacture these filters water protected so that they can be wiped with a wet cloth to clean them in an instant.
This dark red infrared filter is ideal for those who want to get started with infrared photography. It is the essential companion for many B&W infrared films like Ilford SFX, Rollei Infrared and Adox HR-50. The filter has a double filterfactor (2x), which means that when using this filter the exposure time must be doubled or the aperture must be opened by an extra level. Compared to infrared filters with higher factors, this filter has a rather low factor which means that you can still shoot handheld with most infrared films and still enjoy the infrared effect. Should you prefer a stronger effect then an infrared filter with a higher factor is more suitable for you.
