Anamorphic Chop Shop – Kowa B&H Edge Blackening

November 13, 2016

Following the steps of James Price, this episode explains how to dial down the strong veiling glare in many anamorphic adapters. For this example, I’m using the Kowa B&H. The process is cheap, fast and safe. What else could you wish for?

Moving forward with the series of Kowa B&H tweaks and improvements, this one was presented by James Price (frequent collaborator by now!) on EOSHD a while ago. You might’ve noticed veiling glare in many shots I made with the Kowa – particularly noticeable on wider lenses. Veiling glare is this white halo, or inverse vignetting that comes from strong light sources hitting the front optics.

If you’re not too fond of that aspect of the lens there’s an easy way of modding it. The edge of the front element is exposed on the Kowa B&H, which is both good and bad. Bad because it creates glare, good because that gives us the opportunity of fixing it ourselves with no disassembling.

You can be fancy and get acrylic paint and a fine brush to cover the rough edge (its rough aspect is great for absorbing and adhering the paint) but, as I wanna be cheap, I’m just gonna grab my trusty sharpie and carefully paint the edge. It’s easy to see what the edge is as it is… rough. If you have any track accidents during the paint process, just use a Q-tip with a tiny little bit of lighter fluid to wipe the paint off the front glass.

Here’s a little bit of before/after comparisons. For me that’s a LOT of improvement, as I find veiling glare one of the most negative types of flare as it’s too much like an inverse vignetting on a majorly dark frame.

Here are a few more comparisons, these ones by James Price. He states that “this ‘modification’ can also be applied to any similar lens that has an exposed front edge of its optic, creating a strong veiling glare. Often the veiling glare is part of the joy of anamorphic – but sometimes it can be a little too much, so this technique is good to try a little bit at first – by applying a thin layer of diluted paint first (that way, the veiling flare can be ‘deadened’ rather than completely removed.)”.

Cheap, simple and effective, just the way we like it. What’s your opinion on the Kowa’s veiling flare, is it good or bad?

While the next video doesn’t come out, take your time and catch up on the articles you didn’t read at the blog. Last week we had the comparison between the B&H and the Elmoscope II, so check that out too! I’m Tito Ferradans and I’ll see you next week.
