Just bouncing around, doing my thing...

| | | Posted by JiveBunny I was having a look at a hot shoe light but wasn't sure if that would be enough illumination.
| Depending on how big some of your locations get, there are some options out there for throwing light around. It just all depends on your budget and how much crap you want to drag around with you. Hot-shoe light panels are really nice to use. The one thing that I will suggest is to go after panels that are designed to work with camera batteries (like the Sony F970 for example). It was the best decision that I made and I don't have to change out 18650 or AA batteries anymore while I'm out and about. Ryobi makes some decent 20 watt, 18 volt, battery-powered LED work lights that work great with scrims and they can be tripod mounted. But they're also bulky (if you're trying to use a backpack) and not exactly a feather either. I also have a few pairs of cheap Amazon "1500 lumen" portable LED work lights that work pretty darn good for accent lighting and fill lights. They're like $25-$30 for a pair and take 18650 or AA batteries. They're roughly the size of your hand and they're easy to toss into a camera bag or backpack.

| | | Posted by SaladKing Also what's been said about laserpointers; I use mine to manually focus though, rather than trick the autofocus.
| It's not "tricking" the AF, rather it's giving a specific spot for the lock. There are no competing targets because of the beam's intensity. Even hundreds of yards out it's a bright, high contrast target for the AF. Being coherent light means little loss over distance and as the beam diverges slightly it gives a larger target. The AF "likes" it because it's very high contrast target which is what they lock onto the easiest. Some cams like Sony have used this for night AF. Edit... damn spell check

I guess my camera doesn't like the laser or my laser's too weak; I've never had my autofocus lock onto it before, hence my manual focusing. At long range, the red dot might as well be invisible. I'll do some experiments with it to see if I can make it work, thanks for the heads up.
| The one I used was a red 535 nm one. About 1 mw or less. That was with Canon cams. Lock up should be very fast. If it's a 556 nm one, it may get filtered out by cam optics as it's getting nearer to the IR bandwidth. A green laser may work better as it's near dead center in the visible spectrum. The human eye is most sensitive wavelength of green which why at the same lumen level green will seem brighter than red.

Write something and wait expectantly.

| | | I hate using on-camera flash, so I typically will reflect the light from a powerful flashlight/torch by shining it onto the ceiling or an adjacent wall. This will work much better if the walls are light-colored and be less effective on darker walls. Using my flash off-camera (in “test” mode), allows me to create a quick, powerful burst of light very quickly, like a strobe. An advantage of the strobe technique is that your light will be more evenly distributed. Both methods will allow you to get creative with the angles and direction of the light source, although any technique that involves the manipulation of your light source will take a fair amount of practice to get consistent results you are happy with. Some times I’ll also use colored gels for a unique effect. Gels are little pieces of semi-transparent plastic that you can place over your flash or torch to create interesting lighting effects, including an array of different colors. One member here, Imbroglio, has some amazing examples of using gels in his photographs to create some really interesting effects. Lastly, keep in mind this is not a good technique if you’re trying to remain stealthy or could be seen through windows to the outside! ***Slightly off the subject but related: Be sure to set your shutter on a delay or use a remote shutter for long exposures. Even on tripod, you’ll move the camera when you depress the shutter button*** Happy shooting!
