The new way to filter
White balance shifts are Green or Magenta to
correct for artificial lighting. To add warmer to
cooler tones it can be shifted to Blue or
Amber.
Back in the days of film I had a dedicated camera case for filters which
contained over 60 of them . . . that's right, over 60!

I had a filter for every situation which was necessary since transparency
film only came in Daylight or Tungsten balanced.

Today you actually have all those filters built right into your camera with the
exception of a polarizer, graduated neutral density and some specialty
filters.

The one lens accessory you should always have is a lens hood/shade to
keep stray light from hitting the front lens element and causing ghosting or
flare.

If your lens doesn't come with the dedicated one, you can buy several
different types like this metal screw in type below.
Read Your Manual

In the menu guide you will find information about white balance. By
using Auto the camera will determine the best WB level in Kelvins for
the scene. You can use the Pre-Sets
or in some bodies you can dial in your own setting. Changing the
White Balance shifts the color temperature to either a warmer or
cooler look. You can then hit the right side of your multi-selector dial
to get into the screen below and adjust it even more.

In order to cover this subject in depth, it would take more than a
single page article. The best approach is to either experiment while
reading your manual or take a Workshop on White Balance and
Color Correction.
To the left is a 3 stop graduated neutral
density filter to balance bright skies to the
foreground.  Many people by-pass using
grads and use the grad function in post
production software. By taking a class on
filters/light, you can learn why it's a good idea
to always go for the best possible image on
location rather than fix it later.
To the left is a Hoya
HD Clear filter which
protects the front
lens element from
impact, sand or salt
spray. Always
buy the better quality
filters to maintain the
best image quality.
To the left is a clear B&W MRC nano XS-PRO filter and a
smaller Nikon A2 filter. The Nikon filter is what you would call
a warming filter that adds approximately 200 degrees to the
color temperature.
You can actually use these on digital cameras or just shift
your white ballance to Amber (A) by 2 (A2).
If you dial in your own White Balance, you'll find that
you can replicate the look of film. Again this is a
topic that should be discussed in depth or you should
do experimentation to get an idea of what you can do
with your digital camera beyond Auto Mode.
Below is a Tiffen Circular Polarizer. As you can see the
reflection from the table is a lot less when viewing it
through the filter. Polarizers reduce reflections and
saturate blue skies.
Below is our Hoya HD Clear filter to show how
these filters do not reduce reflections
like a Circular Polarizer.

Cinematic and Photographic Ethics - I provide cinematic and photographic services to a variety of clients using the best equipment suited to the project at hand.

I do not engage in "setting up images"  by means of staging. There's a difference between creating an advertising campaign and actually catching life as it happens.

All digital pictures are processed like film pictures. They are captured in RAW/NEF format, then uploaded and exported in a RAW/NEF file converter like film in a developer.

I do not alter/manipulate pictures. I prefer that they look just like what I saw when I pushed the shutter button. If I alter/manipulate an image, it is clearly marked as such.
