Rain!

Perfect flying conditions?

What’s this? A Brit talking about the weather?

Never!

OK, so we do have a reputation for being obsessed with the weather but nevertheless the genesis of this post is the onset of rain.

I’d been expecting it; the forecast (see below) had suggested we’d wake up to rain which was frustrating as, having created my first aerial panoramas a few days ago (blog post to follow), I wanted to try out the onboard panoramic function within the DJI app. I’d not been able to get out yesterday and it was looking like I might need to wait until next week so when I left the house this morning and it was dry I decided to seize the day.

Arriving at the location I went through the pre-flight routine that I’ve become reasonably adept at now and the Mavic was quickly up in the air and hovering at 200 feet ready for the planned shot. A quick shot to check exposure and I was ready. I fine tuned the composition, bringing the drone down to around 150 feet and set the controls for a spherical panorama which would need to capture 34 frames to work its magic. As I pressed the virtual shutter button to start the sequence a drop of rain fell gently on the control by my finger, then another, and another until it was properly raining. Less than ten frames in and the rain had arrived! I was thinking furiously. 

My first thought was “it’s OK, the rain is coming from behind the Mavic so won’t get on the lens”. Typical photographer, but this however was very swiftly followed by “I know it’s not waterproof but what about a little shower?”

Fifteen frames, not even half way. “I’ve seen videos of these drones being flown in snow storms so a light shower isn’t going to hurt”. Eighteen frames. “But those guys know what they are doing, I’m still learning”. Twenty one frames. “I’m not stopping now!

Twenty six frames. I wipe the rain from the face of my phone which is being used to control matters. Thirty frames. “I’m sure it is taking longer between frames”. Thirty two frames.

“Thirty four, finished!”  Must just stitch it first though, after all that was the purpose of the experiment”. I know, agonising for most of those thirty four frames and then I leave it up there whilst the app processes the images without knowing for sure how long the process would take! But this was the process I wanted to test out.

It looked OK (see above) but I couldn’t zoom in to check I’d got all of the lock gates, which are worryingly close to the edge of the frame …

By now it’s raining steadily so common sense takes over and I bring the drone back, flying backwards to keep rain from the lens but still looking for compositions as I bring the Mavic closer.  I can’t resist a few more single frames as I bring the Mavic ever closer and finally back down to the landing circle at my feet. Swiftly wiping rain from everything I’m packed up and under the shelter of a large tree in no time.

Checking the flight log it’s taken me considerably longer to pen these notes than the events they describe.  But I’ve added to my knowledge and experience both during the flight and whilst writing this.  As always when a flight finishes I have that mixed feeling of relief that I’ve brought the drone back safely mingled with a desire to get back in the air. I’ve two fully-charged spares in the bag on my shoulder so plenty of capacity for a longer flight – but it is actually raining quite heavy now and for the second time in five minutes common sense kicks in.

Processed completely on my phone before bringing drone back down.

Sat in the cafe with a coffee I was pleasantly surprised that the spherical panorama rotates gently when viewed via the DJI app although disappointed that when downloading it all I get is the long thin panorama rather than the spherical version. Something else to research, but in the meantime I keep looking at the gently rotating sphere, more than pleasantly pleased that the earlier research had paid off and Woodside Mills locks are virtually dead centre of the sphere as the image above shows, The tiny dot almost dead centre is my landing circle. I will reprocess the 34 RAW files later on the computer but for now am very happy with my short but eventful trip.

Walking back along the canal I was able to appreciate the fresh, warm smell you get when it rains for the first time in over a week. Heedless that the tree pollen season hasn’t quite finished I breathed deeply and savoured that unique aroma. I do like the rain!
