Some types of lens filters can be pretty expensive, and when we’re on the budget, it’s time to go DIY. Ryan Connolly from Film Riot shows us some of the cheap and easy filters you can make at home. They work for video, but for photography as well. You probably already have most of these things lying around the house. And even if you don’t, you can get them for a few bucks and start your little filter experiment.
Using ND filters is a great way to get creative with your photography, creating motion in your images with long exposures, being able to shoot wide open in full sun, producing smooth silky waters are just a few ways to have fun with them. In this blog I show you how I used a cheap eBay variable ND filter to produce these images below and then compare the images using more expensive and excellent quality B+W filters.
We’ve all come across a situation where we’ve had a filter on a lens that just wouldn’t come off. If you haven’t, you will one day. Switching environments, or just leaving your filter on there for too long can cause it to pretty much become embedded into the front lens element. At other times, cheap filters, or the wearing down of coatings on the metal lens ring or filter itself can lead to galvanic corrosion.
In a recent podcast at Tested, former Mythbuster Adam Savage recounts the story of how he removed a shattered filter. How did it become shattered? Well, Norm’s Canon 24-70mm f/2.8II lens fell to the ground along with his shiny new Canon 5D Mark IV after his hand got knocked walking into The Cave. After much panic to determine whether it was just the filter or the lens elements had cracked, the plan began to get it off. A task which turned out to be easier said than done.
A few years ago I broke the filter on my 24-70 2.8 Nikon lens. I felt quite the lucky guy, as that lens is about $1,800. The comments on the usefulness of that filter were mixed. I think the comments on how the new Sigma filter protects a lens will be different.
On December Sigma announced that they are developing a new ceramic glass filter that will be stronger than any other filter you know.
Sigma released a video that was very slick (we will link it below) but did not show much of the action. Now Sigma released another movie showing how a 49 gram metal ball is dropped from 127 centimeters onto the filter and the filter survives. (None of the other branded filters do… ). Why 127 centimeters, and why 49 grams? I don’t know. Maybe it those symbolize the first and last names of Sigma founders.
If we had a breaking news section, this would probably be breaking news. Best Buy just introduced a new family of filters – “Natural Density Filters“. You can get them right here.
So, this is obviously a typo (confused with Neutral Density Filters) and thing will resume to normal as soon as the Department Of Web Sites Categories gets their hands on this and makes a fix. (Hopefully, they will not have to throw all their stock of Natural Density Filters and replace them with Neutral Density Filters as throwing away so much stock can be quite expensive.

P.S. If Best Buy says that they don’t carry this kind of filter, just point them to this screen grab.
Did you know that that when you use a polarizer in a wet forest, the color come out more vibrant because of the water’s effect through the lens?
Up until today, the only two things I knew about polarizers were that they make things go black when you put two together, and that they’re a feature in my American Optical Pilot Aviators (insanely affordable for their quality). Photographer Steve Perry, however, is so passionate about the polarizer that he made a ten minute long video tutorial over it. And don’t let that throw you off; this video doesn’t waste time. He spends ten straight minutes teaching you about polarizers, and it’s one of the most informative little pieces I’ve seen for a while now.
