All my pics are now on ASA 100, I have dumped electronic flash completely in favour of my high power LED lighting, and I am using expoure times of up to 30 seconds. This does not represent problems as I always work solo. Having said all of this your picture is truly amazing, a word that comes to mind is "unique", meaning that we shall probably never see another like it.

There should not be any. Its a matter of duration. Electronic flash is I believe 1500th of a second, LED lamp is on as long as you like. I tried multiple flashes on a hand held flashgun but the capacitors would not recharge fast enough for me so I gave up and moved to LED lamps. -- ''the stopes soared beyond the range of our caplamps' - David Bick......

The downside to this is that there's a lot of equipment required. It's certainly possible to get people to stand still for 1/60 second, but 30 seconds is a lot more challenging. And again, conversely, it's easy to carry around a single high-power LED torch, but a lot more hassle to carry four flashes. At this juncture, I think I'll keep quiet about the dozen or so Metz flashes that I've sold in the last 18 months, suffice to comment that I suspect the ones used in this case probably didn't have the bulky external battery packs 'Open flash' certainly is going to deliver better results, it's just a shame that there's a lot more hassle involved. -- Filling space until a new signature comes along...

To take a photo similar to the winning one with a lamp you need several of them at this power pointing in various directions to take a pic at 1/30th or 1/60th of a second. -- Gold is where you find it IP: 95.148.1.110

It should get you a similar effect to 4 flashes on one shot, as long as you watch out for overlap creating hotspots. -- In your mines, Taking your pictures... IP: 86.154.111.143

My first memories of mine exploring in the 60s led me to want to record the scenes I'd seen. The only camera I had access to was my Father's old Ziess Ikon bellows folding bellows camera which used 120 roll film. Originally there was no facility for flash but we had it modified to sync up with a flash gun using 1/60th sec. Of course for underground work using the open shutter technique it was not needed. I can remember setting the whole thing up on a tripod and wandering around a stone mine trying to illuminate sections and then trying to get back to the camera without leaving snail trails of cap lamp or falling down. Then of course you had to wait for the results which depended on such factors as, when was the next time you would be near somewhere which took in film for developing, could you afford it? and then the anticipation of whether or not you had a decent photo. If you did then the little square print that the 120/ 2 1/4 inch negative produced was incredible and again if you could afford it, you would have the image enlarged. I always used Ilford Black & White film, colour was only used for special occasions. Slide film was just too expensive. Sadly I've lost the negatives along with others I took in Ecton around the same time and those of a trial adit in Chrome Hill. I was taught that the lowest speed that you could hand hold a camera successfully was 1/30 sec, 1/60 sec being better. How times have changed. IP: 81.135.85.99

Your flash gun that gives 5000lm, would you consider it a small / medium big one? just trying to get a feel for how many lumens they give out. I have seen all sort of figures quoted, by people - up to 75,000lm on some. It would be good to getting a definite figure - is yours straight from a data sheet or calculated? One manufacturer of flash tubes quotes about 40lm/W of electrical power, but these seems far too low. 5000, even 10000lm makes it feasible to make a LED flash gun, consuming a fraction of the power a flashtube one does. -- Mr Mike www.mineexplorer.org.uk IP: 79.70.65.221

I hope the winning photo had scale. Better to have a professional instead of a banker. Hi Tony I'm stopping short of moderating these sorts of comments; but would you mind drawing a line under this please. Very Sorry Perhaps I should limit my comments to Ukcaving, until I get banned. Cannot promise to completely refrain from `Scale' as I might be giving a prize at next years Hidden Earth. Sorry not to have replied earlier, I have been on my travels: see under Raasay Iron Mine.

ASA 100 setting, F5.6, 20 seconds exposure working solo. Forground triple P7 photo lamp, centre MagnumStar on full blast, far reaches same as forground. Thing is, we all have our own styles.

Can I do it with my camera?? Panasonic Lumix FZ28?? Yes, but... You're going to need several slave flashes, each equipped with a light sensor that triggers them when the flash on the camera fires. I see no reason why you shouldn't be able to something similar, but it's going to take a bit of practice. I'm using a Lumix LX3 (two trips ug so far) and I'm quite impressed now I've figured out what the buttons do. That said, I've probably taken in excess of 6,000 photographs underground and none come close to Mark's photo! I'll start another thread, but would anyone be interested in a photo trip somewhere in North Wales sometime around Christmas / New Year? -- Filling space until a new signature comes along...
