What does the graduated pink filter do and what for?

I have a nikon D5200 and need to phone what the clear faded into pink len filter does and when will i need it?

Added (1). That does not make sense that there's no such filter when i have one?

Added (2). I don't know how to respond lol so i'm adding once again thank you everyone! But seriously it says pink grad 52mm heres my order details…

This is a Graduated Pink Filter 52mm which will allow you to take pictures with partial coloring.
The design of gradually decrease near the center of the filter allowing emphasis of foregrounds or backgrounds. Color of lens gradually fades out, so the boundary between the colored and transparent sections of lens will not become apparent even with the lens aperture stopped down.

This filter is mounted on rotating frame, so you will be able to rotate the coloring at any part of your image. Giving your landscape and skin texture a more colorful touch.

Double Screw Mount
Included: 1 Graduated filter pink 52mm

Lol i'm not crazy right? Says pink looks pink but can't find any information on it online… Hmm. Odd?

I appriciate this so much!

Never, if you want to ruin a photo use instagram

There's no such filter.

Look on B+W and Hoya websites to see what filters are available. If you have the 18-55 mm lens, then you need to buy 52 mm filters

Are you sure its pink? What are the letters/numbers on the side?

I think you probably have what is known as a gradient Tobacco filter- not really pink but more of a sepia colour. They are often used by those taking landscapes or similar pictures- the upper more densely shaded area both reduces the light from the sky and enhances the sunrise/sunset shades.

To use these filters, you meter on the lower half of the area so that is correctly exposed and then the upper gradient area reduces the brightness there so it is not overexposed and you retain detail in both the top and bottom. These can come in screw on format (and then you need to adjust it to make sure it is properly set)- but most of these are "drop-in" filters- a screw on adapter that lets you then slide in the filter- letting you adjust how much of the gradient covers which area of the picture

Yes, pink color grad filters exist - and not only the one you have ;-) They are e.g. Produced by Tiffen and Cokin both well known filter manufacturers.

The pink filter is mainly used to get a sunrise tone to rather washed out skies. An example is found here:

To achieve this effect you will have to rotate your filter so that the coloured part is on top. So the topmost part of the picture will be coloured more while the colouring is reduced towards the center and there will be no colour in the lower part.
But you can also use it to select other parts of the picture to be colored. As you are using a digital camera you can easily make comparison pictures to see the effect.

What for? Looks better sometimes - adds colour to a boring skies etc. At least that's what they are meant for.

Hope that helps.
