Do you still use color correction filters with digicams/DSLRs even with AWB and PS around? Why?

With film cameras, yes but I don't think it's necessary to use CC filters when using digital cameras.

I did a bit of research and test and here it is.

The theory goes like this: If you shoot in an environment with very
low color temperature blues are very underrepresented. You can say,
they are underexposed. During white balance no matter whether in the
camera or the raw converter, the blue channel has to be pushed up
more than the red and green one.

See the general Wikipedia entry on Colour Temperature at:

<http://en.wikipedia.org/wiki/Color_temperature> (http://en.wikipedia.org/wiki/Color_temperature)

... and scroll down the page to the "Spectral power distribution plot"
heading. Have a look at the graphs and you'll see why you need to
filter excess red+yellow frequencies from incandescent light sources.

See also the spectral distribution curves for various indoor lighting
options at:

<http://tinyurl.com/ykvtr4> (http://tinyurl.com/ykvtr4)

Hence using a blue filter to correct the light colour as much as you
can before it hits the film/sensor.

Other colors applied.

Can't notice any difference though on my test. Maybe i need to calibrate my monitor or better my eyes :)

Thank you for sharing that very useful piece of information. :)

I haven't used CC filters in a very long time. Shooting in RAW is sufficient enough for me :D

The preset white balance setting on the camera is also a good way to get the white balance correct.

I've heard a lot of good things about this filter. http://www.singh-ray.com/goldnblue.html

Pretty expensive though. I hope it's worth it.

You really get your money's worth with Singh-Ray filters. They are hard to get right now as there's a backlog of orders especially with their polarizers. Glad that I got my grads early.

other than cpls, nd grad filters, and infras, i dont have other filters.
