VND & CPL Filters Guide

Why every serious operator carries a variable ND and a circular polariser. Stop reflections, hold shutter, and protect the cinematic look in any light.
Overview
Two filters live on the front of almost every serious operator's lens: a variable ND and a circular polariser. They solve different problems, and between them they let you protect the cinematic look in any light.
A variable ND (VND) is a darkening filter you can dial up or down. It cuts the light reaching the sensor without shifting colour, so you can hold a slow cinematic shutter and a wide aperture in bright daylight instead of being forced to stop down or speed the shutter up. A circular polariser (CPL) manages reflections and glare, rotate it to kill reflections off glass and water, deepen skies and saturate colour.
What's Inside
- VND (Variable ND): a darkening filter that holds your 180° shutter and wide aperture in bright light, with no blown highlights
- How it works: two stacked polarising elements you rotate to add or remove density (roughly 2–8 stops)
- Watch the cross: pushing a VND to its extreme can show an X-shaped uneven patch, worst on wide lenses
- CPL (Circular Polariser): cuts reflections off glass and water, deepens blue skies and boosts saturation
- The CPL trade-off: it costs about 1–2 stops of light and works strongest at ~90° to the sun
- On set: run a VND for exposure, and reach for a CPL when reflections or sky are the problem

Filter workflow explained
The VND explanation demystified why my footage looks weird at extreme densities. The CPL rotation angle guidance (90° to sun) saved me from flat skies.

Professional filter mastery
Now I understand stacking and the cross effect on ultra-wide lenses. The 2–8 stop range for VND is spot-on for my kit.

Useful filter guide
Good practical tips on CPL angle and VND stacking. The cross-effect warning for wide lenses is real.
Questions, answered
What am I actually buying?
A PDF guide on the subject on this page: a one-page on-set reference for the library guides, and a longer multi-page guide for the Complete Camera Guide. Nothing physical is sent.
Is the Full Library cheaper than buying guides one at a time?
Yes. The Full Library gets every library guide in one payment for less than buying them separately, and the discount is applied automatically at checkout when every library guide is in the cart. The Complete Camera Guide is a standalone product and isn't part of that bundle.
Can I print them?
Yes. They're laid out to print and pin up, and most people keep them on their phone for set as well.
How do I get the files after I pay?
Delivery is instant. As soon as the payment goes through you get a confirmation email, and the download is saved to your dashboard: sign in with the same email you used at checkout, open your purchases and download from there. You can come back and download it again any time.
Do you ship anything?
No. Everything here is a digital download: nothing physical is posted and no delivery address is needed.
Can I get a refund?
Because the files are delivered instantly and can't be returned once downloaded, there are no refunds for change of mind. If a file is faulty, won't open, or is materially different from what's described, email sales@mdmmarketing.com.au and it will be replaced or refunded.
Can I share the files with a friend or my team?
Your purchase is a personal, non-transferable licence for your own projects, including paid client work. The files, download links and account access can't be resold, shared or redistributed.
I paid but nothing arrived. What now?
First check the spam or promotions folder for the confirmation email, then sign in to the dashboard with the exact email you entered at checkout: the download is there even if the email is delayed. Still stuck? Email sales@mdmmarketing.com.au with the email you paid with and it will be sorted.
