Kase Revolution magnetic ND1000 95mm

Thanks to the magnetic ring, this Revolution ND1000 gray filter is easy to mount and remove on the lens. The filter is made of high quality Wolverine glass, this ensures that the filter is almost indestructible. Use this filter to reduce brightness by 10 stops.

ND (Neutral Density) gray filter
ND gray filters are used when shooting with slow shutter speeds, to control the exposure time of a scene at the time of shooting. The gray filter thus affects the amount of light, which reaches the sensor. The extent depends on the strength of the ND gray filter used. Gray filters do nothing else with the colors in your photo, making it easier to work with a slower shutter speed or open aperture. In addition, Kase filters have accurate IR coatings, providing true neutral color within a captured image, without the color cast normally associated with long shutter speed photography.

Thanks to the magnetic ring, this Revolution S-GND0.9 soft gray gradient filter 82mm is easy to mount and remove from the lens. The filter is made of high-quality Wolverine glass, which ensures that the filter is almost indestructible and color neutral. 
The magnetic filter can be mounted on a lens with the supplied magnetic adapter ring, but can also be used with the optional Revolution inlaid ring of 82mm.

The edge of the filter has 3 orange bars, which ensure recognisability, the bars also represent the number of stops of light that the filter blocks.  




GND (Graduated Neutral Density) gray gradient filter
GND gray gradient filters have a gradation (gradient) that varies in strength and density across the surface of the glass filter. The filters are often half ND gray filter and the other half is clear. When photographing with long shutter speeds, it is important to be able to control the light. Depending on what you want to block the light from, you can place the gray gradient filter in the correct position. A GND gray gradient filter is often used together with an ND gray filter.

Characteristics:

• Kase Wolverine glass with high optical clarity
• Virtually unbreakable
• Nano coatings, which control reflections, repel oil and water, and are mold resistant
• Scratch and shock resistant
• Color neutral
• 0.9 is 3 stops of light reduction
• Gray gradient filter size 82 mm
• Soft transition

The edge of the filter has 4 orange bars, which ensure recognisability, the bars also represent the number of stops of light that the filter blocks.  




GND (Graduated Neutral Density) gray gradient filter
GND gray gradient filters have a gradation (gradient) that varies in strength and density across the surface of the glass filter. The filters are often half ND gray filter and the other half is clear. When photographing with long shutter speeds, it is important to be able to control the light. Depending on what you want to block the light from, you can place the gray gradient filter in the correct position. A GND gray gradient filter is often used together with an ND gray filter.

The magnetic filter can be mounted on a lens with the supplied magnetic adapter ring, but can also be used with the optional Revolution inlaid ring of 82mm.
The edge of the filter has 3 orange reverse bars, which ensure recognisability, the bars also represent the number of stops of light that the filter blocks.



R-GND (Reverse Graduated Neutral Density) Reverse gray gradient filter
R-GND gray gradient filters have a gradient that varies in strength and density across the surface of the glass filter. Half of the filters are clear and the other half is a GND gray gradient filter, which becomes lighter at the top. When photographing with long shutter speeds, it is important to be able to control the light. Depending on what you want to block the light from, you can place the gray gradient filter in the correct position. In a landscape scene the sky is normally brighter than the foreground and at sunrise/sunset a fairly narrow beam of light around the sun is much brighter, so an R-GND filter is placed in front of the lens and moved to a position where the brighter part of the scene is covered by the R-GND filter and the margin between sky and sun, along with the margin between the sun and foreground, are blurred using the transition zones of the R-GND filter. The scene is normally metered for the highlight area and shadow area and the difference in stops dictates the strength of the filter used. Using an R-GND filter avoids the heavy darkening sky normally associated with using stronger GND filters in sunrise/sunset scenes, the transition zones are normally soft.

Solar eclipses are a rare phenomenon; a total solar eclipse even more so. Unless you are lucky enough to live on the path of totality, you will need to travel to a suitable viewing location. Given their predictable nature, several websites and apps can help you find and map the path of solar eclipses, such as TimeAndDate, NASA, and Wikipedia.

Upcoming total solar eclipses

April 8, 2024
An April eclipse, the path of totality for this one will run across North America, from northern Mexico, through Texas and the US Midwest, ending in eastern Canada. Weather permitting, many major cities will see totality, including Dallas, Montreal, Cleveland and Austin.

August 12, 2026
Europe will then be treated to a total solar eclipse in 2026, which will be visible from Greenland, Iceland and Spain. Weather permitting, several major cities will see the totality, including Reykjavik, Bilbao, Zaragoza and Palma. Most of Western Europe will experience a partial solar eclipse.

August 2, 2027
The path of totality for this 2027 eclipse passes through North Africa and the Middle East before ending over the Indian Ocean. Egypt will experience the longest period of totality, lasting up to 6 minutes and 22 seconds near the city of Luxor, making this the second-longest solar eclipse of the century. Given the climate, time of day and exceptional length of totality, this is probably the most favorable viewing position for any solar eclipse in this decade.

July 22, 2028
The last total solar eclipse of the decade will occur in 2028, when Australia and New Zealand will witness an eclipse with a maximum total duration of more than 5 minutes. This eclipse will be notable because it will pass over Sydney.

If you plan to photograph a solar eclipse, whether it is a complete solar eclipse or a partial solar eclipse, preparation and safety are of the utmost importance.
The first thing you need to be aware of is that there are dangers associated with seeing a solar eclipse. Never look directly at the sun with your naked eye, especially through your best telescope or binoculars. At best you burn your retina; at worst, you can become instantly and irreversibly blind. Always wear solar viewing glasses. This also applies to your camera with a telephoto lens, always use a good filter, which significantly reduces the amount of light that gets through. Pointing a telephoto lens at the sun without any form of protection for your belongings is a very bad idea. A telephoto lens increases the intensity of sunlight and in extreme cases can melt your sensor!

Gray filters do not affect the colors in your photo, making it easier to work with a longer shutter speed or an open aperture. In addition, Kase filters have precise IR coatings, which provide a true neutral color within a captured image, without the color cast normally associated with slow shutter speed photography.
