The product line of the European brand Irix EDGE, which already contains the popular and trusted round UV & Protector, C-PL and Full-ND with its different densities filters, is expanding to include a whole new family of square 100mm system filters (Full-ND and Gradual).
Irix Edge IFH-100 Holder
The Irix EDGE 100mm system is a square (100mm wide) filter system is based on Irix Edge IFH-100 Holder which combines a maximum of compact and light design with a range of practical solutions such as ease and speed of use. The IFH-100 Holder is compatible thanks to its dedicated adapters, including all lenses with thread diameters from 52mm up to 95mm.
Secure your filter- Irix Edge Square Filter Protector Set
The Irix Edge Square Filter Protector Set is made of black, light-absorbing material that also dampens any shocks perfectly. The protector has two functions: to protect the filter against accidental damage, and to protect the edges of the filter from any light beams trying to seep through the edge of the filter, thereby improving contrast and preventing the formation of any flaring.
On the day of launch (12.09.2018), the following Irix Edge Square Filter Protector Set will be added tothe first 300 filter orders from the Irix Edge IFH-100 family.
Gradual Irix Edge 100x150mm Filters
When it comes to those scenes where there is a significant difference between those areas of light and dark, we sometimes have a problem when it comes to registering information simultaneously in the light or dark parts of the image, often due to the technical limitations of camera sensors (or photosensitive materials). Professional digital full-frame cameras (35mm) allow you to record a scene within which there is a difference in the degree of light intensity in the order of 15 EV. But even this is sometimes insufficient; therefore, we must use a means of registering more information in lights and shadow than that offered by the camera itself.
For those with older photographic equipment, the problems associated with recording a technically difficult scene may particularly be troublesome because their sensors are not sufficiently advanced to meet such conditions. So the use of square filters is a simple way to breathe new life into cameras – both digital and analogue. Of course, they are a few years behind, but do enjoy a great reputation. This may be due to the nature of their robustness, the colours generated by the sensor, or just straight-forward sentimentality for equipment that has been with us for some considerable time, but we know it all perfectly well and don’t want to exchange these with anything else.
The Irix Edge Soft Gradual Filter
The Irix Edge Soft Gradual Filter is a filter in which the gradient is extended – that is, there is a long transition between full transparency and maximum density (about one third of the filter height). Thanks to this feature, we can obtain a natural tonality of the image when shooting scenes with irregular horizons such as forests and mountainous areas, as well as urban scenes. Its main use is to dim the area of the frame with the sky (naturally the brightest part of the image) which obscures the densest part of the filter, while the gradient covers the irregular horizon line.

The Irix Edge Hard Gradual Filter
The Irix Edge Hard Gradual Filter is a filter where the transition between full transparency and shaded area is narrower. This type of filter works well for scenes where the horizon is flat and regular such as the sea or some wide-open plain. In this situation, the upper part of the image – the sky – is definitely brighter than the rest of the frame and this part should be covered with a filter.

The Irix Edge Reverse Gradual Filter
The Irix Edge Reverse Gradual Filter is a relatively new type of filter that combines the features of a hard and soft filter. It finds its application when it comes to sunset and sunrise photography. Probably every one of us has at least once tried to capture a beautiful view of the sun emerging from the horizon, and then encountering one problem; either the frame was visible, the sun and the horizon has turned into a white spot, or we have managed to capture the sun with a beautiful façade of pastel colour background of black emptiness. This filter in its design allows us to eliminate such problems; it is half transparent, turning to full density (Hard Gradual), and then gradually reducing the density (Soft Gradual). Such a construction ensures that it covers the narrow spectrum of the frame within the horizon line, and so giving us the possibility of ensuring the correct exposure of the photograph.

The Irix Edge Full-ND 100×100
The Irix Edge Full-ND 100×100 is a full ND filter; its entire surface is responsible for the reduction of light. Its use allows us to extend the exposure time in order to blur out movement such as cloud, water or people. This is done through a long exposure; any movement of people is short enough in the frame so they will not be registered on the camera sensor.
The filter is also applicable whenever we want to extend the exposure time; either because we do not want to do it with other exposure parameters available from the camera, or our camera does not allow for shorter exposure because of its faster shutter speed.
For example, let’s say we want to take a picture with soft water (motion blur), and we know that our camera has a minimal native (not extended programmatically) ISO 100, and the lens is the sharpest at f / 4.0-f / 8.0. The optimal settings will include the ISO 100, an aperture of f/8.0, and the time depending on amount of light (during the day it would usually be 1/100 1/2000), and is definitely too short a time to blur any movement. Therefore, we can choose a filter suitable for our requirements (with the desired density) to extend the exposure time.
The ND filters are available in different densities. For gradient filters, the density is usually from ND4 (density 0.6 / 2EV) to ND32 (1.5 / 5EV). The situation is different when it comes to full-ND filters – here, the density range of filters reaches extreme values starting from ND4 to ND1000 (density 3.0 / 10EV), and higher. As a result, each photographer is able to choose something for themselves, knowing their needs (and the limits of their own equipment), as well as the circumstances in which they usually comes to photographing them.

Each filter is packaged in a practical case that protects the entire filter surface from any external factors such as dust and moisture. In addition, the magnetic latch protects the case from getting inside the particles that could scratch the surface of the filter, such as quartz.
