UAV Filter Frenzy!

CreativeCOW presents UAV Filter Frenzy! -- Drones/UAV Feature

Virtually every sUAV/RTF drone in the air uses the same image processing chip and most have similar lenses. None of them are ideal, and they all operate at very high shutter speeds. None of them allow for shutter speed control, and as a result, it's up to the user to slow the shutter speed. This can only be done through the use of filters.

At this time there is no stock UAV/Drone camera that operates out of the box, to its full potential.

There are three types of filters that benefit UAV/drone operators.

  • Polarizers

  • Neutral Density

  • Gradients

  • Each of these filters serve a particular purpose.

UAV Filters - Polarizer
Polarizers reduce the glare found in a scene. This is particularly useful when flying over water or objects that have a lot of shine (waxed cars, metalic surfaces). UAV/Drones do not use circular polarizers that are popular with photographers; drone systems use linear polarizers so that the angle doesn't need to be adjusted.

UAV Filter-Neutral Density
Neutral Density filters allow us to control the exposure, therefore slowing the shutter speed. Most POV/Action cameras/drone cameras shoot at very high shutter speeds which incur nasty contrasts on detail edges, shadows that are unrealistically crisp, and create a sense of unnatural movement. We want our shutter to be operating at less than 1/500 of a second, and the only way to achieve this in small UAV/Drones is to use a Neutral Density filter. Neutral Density filters do not affect color in any way (hence the name "neutral density"); it merely slows/stops the light from hitting the sensor, forcing the camera to allow for a slower shutter speed, giving an image more natural in contrast and blur to the human eye.

Filter-Gradient
Gradient Filters allow us to enhance the sunset, enhance a skyline, or enhance a sky while exposing for the ground. These filters require a specific angle of installation on the drone camera (simply be sure the colored sectional line is horizontal).
Gradient filters also allow for creative adjustment of color. Put a Sunset gradient on during a midday or early morning flight, or put a blue gradient during a sunset to shift the light for creative purposes.

So...how do you know which filter to use when? We've got a handy chart to help you with that!





The ND8, ND8/PL, ND16, and ND16/PL are the most commonly used/needed filters for UAV use.

Check out this video! (best viewed in 4K and full screen, this is a manually-flown example of how the filters work. Forgive the lack of uniformity; it was so hot our tablets melted down and we were flying blind in the 119 degree heat!)




Filters do more than enhance our images and save time in post-production/video editing. They also protect the very expensive camera lens on the front of your UAV camera.

Speaking of protection, remember to keep a DronePen in your UAV case at all times! Clean the lense prior to and after each flight to protect the lens and keep your image dust-free!





 

We are proud to be partnered with Polar Pro, and highly recommend their products for UAV flight for best photography. Visit one of our Drones Plus stores in Hollywood, Las Vegas, Dallas, Toronto, Portland, or Seattle, and our drone experts will be pleased to share even more information with you!

An understanding of the Drone Code may help clarify the lines the FAA and UAS/UAV/drone owners have drawn in the sand for each other, says Douglas Spotted Eagle, CEO of Drones Plus, Inc. The Drone Code may seem to shift at the whims of legislation, lobbyists, manufacturer organizations, government agencies, and UAS users. It doesn't. Here is Part 1 of your path to distinguish shifting sands vs. the solid underlying large rocks anchored to the earth.

Drones/UAVs, Cameras, and Beyond: Douglas Spotted Eagle

When longtime Creative COW leader Douglas Spotted Eagle recently approached us with a suggestion to add a Drones/UAV forum to our extensive cinematography and videography communities, it immediately made perfect sense. And who better than Douglas to host? We also took this opportunity to speak to Douglas about the sweep of his career, from Grammy Award-winning musician and producer, through editing, cameras, training, consulting, to now, as an early adopter and advocate for UAVs.

Drone Rules Suck...and Why You Want Them

Drone Rules Suck...and Why You Want Them

Rules! Why do we need so many rules for drones? Pilot, skydiver, and drone operator Douglas Spotted Eagle agrees, “Some of the UAV/drone rules and laws are not only unreasonable but downright ineffective,” but when you look more closely from a pilot’s eye view, they start to make much more sense. Starting with this principle: common sense isn’t all that common!
