Hot on the heals of version 5.2, comes 5.3. The shiny new feature in 5.3 is the Personnel Deployment Record. To gain an overview of the system, here's a link to a short film.

My Excel-based Cave Rescue Incident Management System (CRIMS) has now been adopted by Gloucester Cave Rescue Group. The system allows easy management of available resources and deployment of personnel/equipment, as well as maintaining an incident log. It can deal with up to 24 teams of 12...

This is the fourth and concluding episode of my three-part series on how a set about making my caving films. It covers, amongst other things, A and B-rolls, Cut-in and Cutaway Shots, The Film Production Process, Salons/Competitions/Film Festivals and Film Judging Criteria.

This is part three of how I make my caving videos. 
In this episode I concentrate on two very important elements of successful film-making: editing and sound.
 I cannot over-emphasise the massive importance of editing. There are loads of people taking video footage on caving trips nowadays but...

This is the second part in a series of videos titled, My Caving Videos, How I Make ‘Em. Part One, was uploaded way back in 2019 and it covered the type of equipment that I use. This part covers: Intended audience, aims and objectives. assembling a team, planning shots, lighting, shadows and...

Thinking of Hanging Up Your Fins? Never Say, "Never Again." The film of Geoff Yeadon's return to cave diving 26 years after he last donned on his fins is now within a cat's whisker of being finished, and I have to admit I am quite pleased with the result. It's very different to anything I've...

I've created a playlist on the Hidden Earth Video Archive YouTube channel (youtube.com/hiddenearthvideoarchive) for the videos that were entered in this year's video salon. 9 videos were submitted but we only have permission to link to 8 of them. No judging took place this year so there was no...

Has anyone used an iPhone for filming their underground adventures? I need to upgrade both my phone and the camera I use for making my caving videos, a Lumix GX7, and the question I'm asking myself is, could an upgraded phone double as my caving camera? The Lumix has always given me very good...

I needed to update my old GoPro Hero 6 so I read loads and loads of reviews and watched loads and loads of YouTube videos. The choice was between the GoPro Hero 11 Black and the DJI Osmo Action 3. They both came out extremely well in the reviews but in the end I decided on the Action 3, mainly...

Tomorrow I'm giving a caving talk to a vintage motorcycle club and I know that somewhere in my library of caving books there is a B&W photo of motorcycle completely laden with caving gear. I would be very grateful if anyone could tell in which book(s) the photo appeared. Thanks in anticipation...

Mrs E. has banned me from using the washing machine to clean my caving stuff so I thought I'd give this a go. :confused:

Keith sets off to go caving with two of his most trusted caving colleagues, Chunky and Loz. What could possibly go wrong in a part of the cave known as the Birth Canal?

I've almost always used the YouTube Audio Library as a source of music for my videos. However it seems now that some of my favourite artists are slowly withdrawing their best creations from the library and I'm struggling to find the sort of stuff I need/like. For example, I've used a lot of...

I've had this headlamp for some time. Here are my thoughts. http://youtu.be/s1X2_AS1pCc

I've just got my hands on the new Fenix HM70R headlamp. My first impressions are very favourable. The 1600 lumen turbo mode is very impressive. Have a little look and I'm sure you will agree. https://youtu.be/KmXbDoNku6U

I've had an idea for a new film. It's at the conceptual stage, and whether it gets made or nor depends on finding caving related words beginning with each letter of the alphabet. I've had a go but I'm really struggling with some letters. Just for fun over the next 26 days, starting with A today...

For the last few years there has been an annual video workshop. These successful workshops were run in South Wales by Antonia and Andy Freem, and the Forest of Dean by Paul Taylor, but this year there won?t be one,  :( unless we have a virtual/online one. I?m working on the script for the...
