I've never used smoke for any of my shots.
The key for me is long exposure.
Both laser and camera on tripods and I set the camera to 30 sec on a high-ish ISO setting, for example ISO 3200.

These two shots are outside with the 80mW 589nm.

Thanks for your pic. With a long exposure a 589nm is definitely look amazing.

Yes, very true, I should have mentioned that.
The higher the power, the less exposure needed, just experiment.

Here's another 30 sec one I did with three beams, each one moving in succession, turning on one at a time during the exposure.
The only reason I used 30 sec is to get this effect.
If I was to do a single beam shot, I'd only need a second or two for the higher power ones.

Another nice one. It is what we call it light painting? :shhh:

Thank you so much Thunder22, glad you like them.
The 589nm really comes up nicely in long exposures because it doesn't overwhelm the camera.
But you can get very nice beam shots with just about any laser power given the right exposure.

I might make another photo with all my wavelengths soon.

As you can see in the pic, even with the lights on, the beams are exposed nicely and are uniform. This was taken using just a few puffs from my fog machine while doing test shots. Exposure was F10 ISO 125 at I would think 3 or 4 seconds, but I turned off the overhead lights after a second to let the beams expose longer

Bruce! Love your photos.

RB Astro. Whats your settings to get that nice starry background with the laser? I usually go for 30 seconds @ f5.6 and ISO 1000.

Hey Ultron,
I think the photo you are asking about was taken by RB Astro, not me.

Yes, I was addressing him?

Oh, my edit isn't saving. Strange. But I was talking to the both of you.

Edit: Yeah, edit is not saving. Keeps loading forever when I click save. Works on this one tho.

This is awesome. Are you manufacturer? :wtf:
Those 5 lasers hanging above really catch my eyes

Hi RB astro would you mind sharing the model of the camera you are using? Also are there any disadvantages of long exposures? If not I am going to make it super long exposure to shot a super visible beam :eg:

In the 589nm shots I think I used 30 sec @f/8 and ISO 3200.
Your setting are close, just bump up the ISO a bit. :beer:

Thank you Sir, glad you liked them. :yh:

I use both a Canon 7D MkII and also a 5D MkII, just depends on which one I grab first.

As for long exposures on a DSLR, no real disadvantages except that image noise starts to build up because the sensor starts to heat up.
You can't damage the sensor but it produces image noise in the photo which looks ugly.
This is where you need to use In Camera Noise Reduction (ICNR).
You set that to 'on' in the camera settings and what this does is the following:
You takes the images for x amount of time, lets say 3 min in 'Bulb' mode.
It then takes another 3 min image straight after the original but this time it blocks the light path and only takes the image of the noise generated by the 3 min interval.
Then it subtracts the noise image from the original image and you end up with a cleaner image.
The only disadvantage is that it takes twice as long to take an exposure.

You can't damage a sensor by long exposures so don't worry, they're designed for that.
Just know that the longer the exposure, the more noise it generates in the image, so use ICNR.

Beautiful image as usual Bruce.

OK so I figured out how to set the exposure time for my camera. I am now be able to take some pics with good looking beam. Still exploring. Thanks everyone.

Glad to hear that dude. Remember to share your pics whenever you have time. ;)
