Been a while since I've done any pictures, and since the last time I did them, I actually got a nice new Canon 60D DSLR to do pictures with :D

First off, some of my new 638 nm, wasn't dark enough to get very good beamshots, but I had fun taking pictures of the shiny host and playing with my camera's depth of field.

Now some of my trusty 445 nm, lots of lens flare with these ones. (any pros got any advice on how to minimize lens flares?)

So at this point, it started getting dark, and trying to manually focus my camera on a dark object in the dark was not fun, so I unfocused my 638 and used it to highlight my 445.

Interesting things I noticed:

First off, in 2 of the pictures some mosquitoes decided to fly around the aperture of the lasers, producing some interesting motion blur effects.

Also, I noticed an interesting difference in the way the "aura" around the aperture of my 445 looks between my camera's RAW format and JPEG format.

JPEG compression gives that classic purple aura, while raw gives a pale blue aura closer to the natural color of 445.

Nice Shots :)

I usually take shots with my 100mm Macro Lens at F/2.8 and iso between 100-200.

Also shutter speed at about 1/80-1/100. That way the flares are lower.

That setting works for me :)

At the end I guess the lens also has a lot to do with the quality.

If you are using a normal kit lens .. I would suggesst to buy a new one.

Nice shots! I typically shoot with my 35mm prime lens set to f/9 with ISO of 200 and a shutter speed of 30 seconds. Although the specifics change depending on which wavelength I am shooting.

This is the lens I use:
CANON EF-S 18-200MM 3.5-5.6 IS LENS 2752B002

Yes it did come with my camera, but given its stand alone price I would hesitate to call it a "kit" lens ;) :)

I do a lot of my photos with the aperture of my lens wide open, I'm thinking that also might have a lot to do with how much lens flare I get. I'll try closing the aperture and nudging up the exposure time and ISO.

One tip Brucemir gave me was to keep my aperture around 9-13. It works well for me.

Lens flare is not only annoying when taking beam shots but it makes you stand out at night, on lookers could even think that bright glare is dangerous so what I often do is use a shroud or a tube around the lens to make the angle of observable lens flare very narrow. That way anyone off to the side sees only a nice clean beam.

Great pictures. I advise lowering your ISO and using a higher F stop, wit a slightly longer exposure to try to minimise glare. If that fails, go down a few stops and try shorter exposures with higher ISO, in short just play around. Lower ISO should mean less flare. Interesting looking at RAW files and JPEG. I'll have to have a try with my D90 when my new lasers arrive.
