Thanks to all, I have read the one that you have linked alrady, just wanted to ask a local about how strictly these are taken and what are my odds to have my drone taken... I will be in the mountain so I think I should be OK.

Cheers,

I'm not a Slovenian local, but the last couple of years I did several multi-day hikes and climbs over there in the mountains with local guys. It is phantastic over there, on top of my favourite list, including the people. So I don't hink you will have any issues over there using your Spark. Wish I had mine already during my last hike in the Savinja Alps. Almost none of the mountainous areas are within controlled airspace. Which part are you visiting?

You should visit Lake Bled in Slovenia, many who visited Slovenia, say it's One of the Most Beautiful Places there.

Awesome footage mate


Thank you so much A CW, it was done by some Hungarian Guy I think.

I notice in the Footage the Darkening of the Sky in some Parts due to the ND Filter when coming at an different angle of the Sun, I need to do a lot of Test about this, or split the Flight in two parts - Adjust ND, Takeoff Land / and Repeat. Or maybe wait till 12pm when the Sun is from the Top ?

Do you have any ideas how to avoid that A CW ? I think Splitting the Flight is the best option, but it will never match exaclty the previous footage.

A lot of people get really hung up about the whole 180 degree rule in keeping the shutter speed to double the frame rate. This is fine for professional hand help cameras but is almost impossible to maintain on drones due to 360 yaws and lighting conditions changing in seconds with the yaw to the angle of the sun. The only principle requirement of ND filters is to create more motion blur for a cinematic feel to the image - if the drone is flying over 100' AGL and is not tracking any moving objects then motion blur is practically irrelevant as there is little to no motion to blur out. In that case, just increase the shutter speed as what is essential, absolutely essential, is the correct exposure value and when using a micro 1/2.3" basic sensor with a fixed aperture it is important to keep the ISO as close to 100 as possible and control the exposure manually with the shutter speed. Motion blur is not as important as the exposure. Use the rule of thirds to keep 33% of the image to the sky and 66% to the ground - the more sky in the image the darker the ground will be. Using graduated filters will help to balance that but again, a 90-180 degree yaw/pan and the lighting changes dramatically.

I learn't the hard that ND filters are practically pointless on drones - bottom line!

It takes a lot of settings and tweeking before the Actual Flight, and also planning according to the Sun Direction if one needs to do 360 Turns as you have mentioned.

An ND16 may be perfect flying at a 45 degree angle then turn away from the sun and your exposure value drops to -1 or more - the only way to then correct the under exposure is to increase the ISO to compensate for the ND filter which creates noise in the image. It's especially difficult during the golden hour as the natural light changes by the minute as the sun rises/sets.

Infact, even when cloudy, as you said the Sun may come out from behind the clouds as cause a lot of variation when in Manual Mode, this happens a lot to me on my DSLRs as I am always on Manual, I was thinking maybe using 12pm when the Sun is High Up in the Sky when doing 360s or will the Shadow look very ugly ?

I think Practicing with trial and error is the best to improve.

Keep practicing mate though it's one of things I am yet to get the hang of

I understand 100% as its one of the most demanding techniques.

Every Scenario is different, daytime, weather, location, they all effect the final results.

Thank you so much for your Time Dear A CW.
