I tweaked the image at the top of the post reducing the shadow around the figure and straightening up the pillars at the back. This Postimage photo has been added in at the next size up.( 17 inch monitor ).
You can easily see the downside to LCM. The image tends to look flat and I was unable to compensate for that by having figures further away. That , of course, increases the risk of subject movement. You also get a light grainy colour cast in the image and editing and cropping can only be minimal. Still when you consider all of the photo gear fits into a small pelicase and the set up takes minutes those effects are acceptable to my mind.
My son Jonathan is over from Australia where he emigrated five years ago. He is well over 18 at 45. He did a fair bit of caving with me when he was younger but never really took to it. Jonathan's Chamber in Withyhill is named after him by me as he was one year old the same month I discovered it 44 years ago. ( tempus fugit ).
