Suffice it to say, these two filters are neutral density filters, which give you outstanding control to dampen down the incoming light. The Mor Slo knocks light down by 5 full stops, and when coupled with the Vari ND, you get an additional 8 stops of darkness. The Vari ND allows you to look through the view finder, compose your image, then to dial down from dark to black. Hugely useful. Otherwise, you would have to guess at your focus point, do a 30 second timed exposure and find the result was out of focus.
So, here are some blur-making shots, with one freeze-frame effect to show the difference.
All the best,
Chris Kiez, a hardcore photographer since the 80's, learned to take a picture before the age of selfies and cell phone photography, training on mechanical cameras and film. After years of taking photos of all manner of subjects and people, he did over a 10 year stint as a crime scene photographer on two continents. Now, he does portrait and landscape photos, and is currently distressing the world with his relentlessly, excruciatingly boring blogging. To buy what you see on this site, click here!
