More Purple Than Blue

You'd think so wouldn't you

I have found that it depends on where I am shining my 445, sometimes it is more voilet than blue. We have had some fires lately and shining my laser at the moutains it looks violet with blue sparkles due to the smoke and paricles in the air!

Sounds beautiful. Unfortunately I wont be in the mountains for another 10 months. :cryyy:

Yeah I have seen some videos when it looks blue and some when it looks purple.

What camera's make of it differs too. I have one that for some reason captures red (650-660 nm) lasers magenta. Its color performance is fine on normal scenes though, those things just arent built for a whole lot of monochromatic light...

Videos are irrelevant .. color there depends on camera interpretation .. and blues are common problem .. it's almost impossible to capture blues and violets correctly.

Thanks you for this. I was wondering why some looked so different.

I wish my camera would have been here to take a pic, my daughter borrowed it. I tried with my phone but they didn't turn out.

I live in the mountains, my elevation is 4900ft. It is actually legal to ride our quads on the streets, I don't have to load up my quad to go riding I am here, get on it and go.
This is from my front door

my quad. 800 polaris


I took these pics with my phone!

Well to me, the beam IS blue. It is a certain sort of deep, techni-color blue. Very beautiful. There is very little violet in there. The only reason you can see the violet is it shows better at higher powers in ambient atmospheric dust. Put your 445nm in a little smoke or fox, and all you will see it pure blue.

is this blue ? or violet ( my first pic of my 445 ) and it's true blue to me

ps: i posted a few pics in multimedia ( first pics )

For me 445nm is royal blue. I think this is the perfect name of the color what is not purple and neither classic blue.

I propose that the word "purple" be banned from LPF unless it is being used to discuss rock music from the 1970s.

 

[DrSid]

Most sites about color theory actually use word 'violet' for fast single line blues. 'Purple' is then reserved for red-blue combinations.

All saying cameras can't capture it well.

Strangely enough mine captures it EXACTLY like my eyes. Even has the same problem of not really being able to focus on it. When the whole room is bathed in 445 light, my camera takes blurry photos. It doesn't care to focus on the beam either. Ive been fighting with that a lot.

What camera is it then ?

It all depends on white balance which your camera calibrates upon exposure. Most probably use auto white balance, if the option is even available. It's easily correctable in any photo editing program.

Taking RAW pictures enables you to do this tuning with the raw pixels captured by your sensor.

Here's a shot made by my Nikon D90 which I find reflects my perception of 445nm well. It is set to auto white balance and manual shutter/iso/aperture. No post-editing except for resizing.
