you can use smoke(from cigs or fog /smoke machine) or some sort of aerosol spray like hair spray(preferrably something less messy) or air freshener

You may need to use manual camera settings, to get a long exposure. A tripod will assure you a photo free of movement blur. Any room lighting will need to be turned down a bit. Smoke, fog, or incense sticks will also help the cause. A little experimenting along these lines will get you results. A lot depends on your camera and what it allows you to set and control. With 50mW, you should be able to photograph the beam. Post your results so we can see them.

The least expensive way is to use JayRob's "smoke in a bottle" trick.

Check out post #16

A hole is cut in the bottle cap and a transparent window is glued over the hole. Then you just extinguish a match and drop it in the bottle. That's how I made my profile picture.


Another simple way to take a beam shot is to use a glass container filled with water....you can make also some interesting reflection effects...

Careful you don't kill your diode with reflection.

mfo:
mmm, I used the wrong word: change reflection with refraction! Sure, this aspect must be always taken into account; using this pyrex container (with the rounded lower edges) it is possible to see a pale horizontal reflection inside the water, while the laser is clearly sloped and at a lower level...:yh:

Any direct reflection can be dangerous when the beam reaches a sufficient reflective surface in a perfectly perpendicular setting....

8" xtal balls work well for blu-ray and green but not so well for red, the blu-ray actuly changes color going through the ball to a light green color and comes out the other side violet, to the camera this light green color appears light blue in the picture, in a closed space I like to use incense it smells a whole lot better than fog from a fog machine.

Usually it happens when in the mix of silica used for make the glass, there was some lightly fluorescent elements.

I noticed it with some glasses, but not all, so no idea about what the responsible element can be, sorry.

that is weird i can take beam pics with my 50mW on my i phone which i think would be difficult because of the quality of the camera

I used to light 4-5 matches and blow them out in a room. But a fog machine makes everything soo much easier.
