5 Photo Tips – some tips about filters, explanations, different types (contd..)

Tip 926 (Grad filter: Fitting light as per dynamic range of the camera): The dynamic range of a clear day can be pretty large, while the camera is only able to capture a limited amount of this dynamic range. Because of this, there will be sections of the photo that are either over-exposed or under-exposed. What a graduated ND filter does is to darken the over-exposed area of a photo (typically images of a bright sky) so that the sky falls within the dynamic range of the camera and details can be seen.

Tip 927 (Grad filter: Available in stops): For photographers, the term stop is fairly common. The same thing is true for the graduated ND filter, which are available in stops. So, when you take a one stop filter, it will reduce the amount of light by half, a 2 stop filter will reduce the amount of light to 1/4, and so on. When taking a photo, you need to get the balance of the stops right or you will get an unnatural looking photo.

Tip 928 (Grad filter: Ensuring that you can get a proper exposure in landscapes): One of the biggest problems in shooting landscapes on a bright day is the fact that when you want to get details of the landscape, the brighter portion of the sky are over-exposed. When you use a graduated ND filter, it ensures that the over-exposed portion of the sky is darkened and the details of the sky are clear.

Tip 929 (Grad ND filter: Ensuring proper positioning of the filter): When you are using a graduated ND filter, you still need to spend some time before taking your photos. Experiment with moving the filter around until the graduation of the ND filter matches with the light levels transition in the composition, so that you are able to define the best positioning of the filter.

Tip 930 (Grad ND filter: Using a lens adaptor for the ND filter): For the best positioning and flexibility of use of the graduated ND filter, go in for lens adapter rings and holder rather than using screw-in ND filters. Using lens adapter rings allows you much more flexibility in terms of moving the transition line of the filter withing the composition.
