lens for creative night shots on aps-c camera?

[413x]

looking for a lens i can use for things like light trails (car lights, night sky etc) and just being creative in general with glow sticks etc

am i right in thinking a wide angle lens would be a good bet?

The only remotely applicable lens is the nifty 50 lol

My only other lens is the 100mm L macro

I've recently ordered a 60d and awaiting is arrival
Btw that is an amazing picture. I love it

Btw I don't understand why you reduce the iso to increase the shutter speed?

The iso rating goes back to film cameras and its sensitity to light. The higher the iso rating the more sensitive it is to light meaning less time is required for the image to be produced on film. Increasing the iso however adds noise / grain which isnt desirable in some photos. The lower the iso rating the cleaner the image in terms of noise.

Thanks. I get that bit
What I was getting at was why would you lower the iso.. Make the camera less light sensitive
To increase the shutter speed... Allow less light in?

Personally is buy a strong ND screw in filter, like the B&W 10 stop. Shutting the aperture down to that extreme will mean you have very soft images. When I forget my ND filter I occasionally do that and end up with really sort results.

ah yes i have just read about these. looks good. im guessing there are many different grades. ill have to research what to get

Just reduce the aperture to f10 - f22 and put the iso as low as possible to increase your shutter speed

thats the bit that confused me

when said increase the shutter speed I meant increase in time terms e.g 1/500th of a second to 1 second. Does that make more sense?

yeah thanks. sorry, i thought that was what you meant but was just making sure i hadnt got confused in my head as im pretty new to any of this and there are a lot of concepts to get my head around

would one of the wide angle lenses being discussed in this thread be suitable?
i can imagine a wide angle lens being useful for more than just night as well

Looking at the 10-22 canon or tokina 11 -
I want planning to use the 50mm for this
I have some extra for a lens as I decided against the 70d
And yes I definitely need an nd filter.. Recommendations? Reviews seem varied

And yes the high iso to start is a good method. I understand aperture, iso, shutter speed individually but not the relationship in detail As in one stop rreduction in X is equal to iso change of y.. Something to learn

Thanks for all the tips guys

Is the softness as high F due to the blades being so tight or something to do with the light diffraction through such a small hole in ratio to the lens?
