    Hey guys, need some advice or pointing in the right direction.

    Yesterday me and a friend took a trip down some tunnels, the pair of us have little photography experience but want to get some more effective shots the next time we head down and I was wondering if anybody could point me in the right direction of some relevant reading for light painting in tunnels or if anyone with some know how could walk me through the theory a little further than holding the shutter open and shining some light about.

    We don't really have much in the way of lighting equipment apart from one flash gun and a handful of flashlights. I have a tripod, I know that is needed but as far as the general practice I'm pretty much stumped.

    Any help or advice anyone can offer is greatly appreciated and not only will it give me more knowledge but it will also improve the quality of pictures that I use on future reports!

    The basis of light painting shouldn't vary. In so much as requiring sufficient light to illuminate whatever subject matter you're wanting to photograph.
    That said different materials reflect and absorb light in various amounts as I'm sure you'll find out if you continue with your interest in Sooty Railway Tunnels ;)

    Whether it's a Derp, Sewer, Factory or Railway Tunnel I always use a tripod as you mentioned (good start there as some people think they can hold a camera steady for 30 seconds;)

    Select whatever aperture you require ? Remembering the more you stop down (raise the F stop number while increasing the septh of field you'll reduce the amount of light reaching the sensor and so will need either more light and/or a longer exposure time to compensate.
    I'd suggest investing in at least a £3 remote shutter release as any unwanted vibrations will affect the final image.
    On a personal level I shoot in A mode if the exposure time will be under 30 secs by the time I've finished doing my thing ; ) or in M in Bulb mode where the shutter is open for as long as you select. So when you have a lockable release you can wander around to your hearts content lighting different areas while the image you're lighting develops as you light areas up.
    Long exps in Bulb mode without a release may pick up vibrations from you moving and even breathing so the £3 release will be a sound investment along with a tripod capable of actually supporting the weight of camera on it without flexing etc.
    Depending on where you are and what you want to create multiple flash units can do the job but IMO light painting is a darn site quicker. But then I'm not creative.

    I'll use F6.7 or F8 on a F2.8 lens for some decent DOF but then I shoot in manual and shoot using Focus Peaking so I know.whats actually in focus (mostly) multi metering (information there's no other sources of light) and paint away. Some jiggle lights about like a Firefly on speed some paint vertically or horizontal. Whatever works for you and the image you want.

    If your gonna carry on with the tunnels I'd suggest you practice on something less challenging first TBH to get the hang of it and invest in some quality lighting for the Tunnels very long exposure times;)

    It's easier to show that explain and others will no doubt suggest other things but all.ill say is look at my tunnel reports and see if you think.theyre acceptable?


    Excuse the rambling as I'm on the non 28DL friendly Mobile and it keeps crashing so it'll be all.over the place as per ,)

    Edit i forgot to say use the Cameras base ISO to reduce noise in the image, ie don"t have it on Auto ISO as the camera will raise the ISO to try to reduce the exposure time, which you don"t want :)

    Thanks Monkey, I'll give this a good read.

    @ACID- REFLUX Thanks for the info, I'll have a play around tonight when it gets dark and see what I can come up with with the equipment I have but I'll certainly invest in some more powerful flashlights than the ones I already have. They are fine for pointing out things and seeing where I'm going but I think I need something with a bit more oomph for painting with. I'll have a look over your reports to get a sense of things.

    I'm having a look at a more powerful flashlight but I'm poor so it is going to be a cheap and cheerful to get me started so if it doesn't pan out I wont be too out of pocket but I'm looking at something with 220 lumens and a quoted 300 meter beam for £22. It's certainly cheapo but has a fair chunk of power so I can paint more effectively without having to dance about in front of the lens and possibly ruining the shot with ghosting.

    Too complicated. Use a Lenser or other torch with a focus. Pinpoint the end of the tunnel and gradually focus back to flood along the length of the tunnel. What you're trying to achieve is the same density of light from front to back.

    Thank you for the input @Oxygen Thief, I will have a look around for something with a focus and start putting some cash aside. Until then I will just spend as much time as I can practising various techniques for utilising what I have access to and seeing what results I get.

    One of these... Lenser P7.2 on Amazon

    Don't even consider buying one from Ebay, it will be a fake, guaranteed.

    Thanks for the tip on what to get and I won't use Ebay, I barely use Ebay in general so no worries there!

    They'll be fakes mate I promise, especially if you bought a pair, PM me a link to the auction and I'll see if they're on my naughty list. BTW, the fake 7.2 is still better than a genuine P7.

    Tell you something I just got myself a led lenser h14r.2. Bloody thing is awesome does wonders for pics etc. And the fact you can use aa also means you can carry spare rechargeable ones with you. And it comes @ACID- REFLUX certified lol. Very good for long drains etc.
