There are many techniques we can use to change certain aspects of our photography both whilst taking the photograph and after using editing software
These techniques include the use of;
- Polarizing Filters
These have a number of uses, they block out unwanted reflections from water and glass, making them perfect for taking photographs in places like zoos and where you might get glare on reflective surfaces. They work best at a 90 degree angle to the light source, and cut out light by around 1.5 stops so you have to take that into consideration when using fast shutter speeds.
- Neutral Density Filters
Reduces the intensity of the light entering the camera, which allows for longer shutter speeds and a shallower depth of field without over exposing the image in bright conditions. An example of where you might want to use a neutral density filter could be when you want to take a long exposure of a waterfall, adding movement to the water.
- Graduated Neutral Density Filters
These work the same way as the normal ND Filter except not all of the filter is darkened, this means you can take a photograph where there are different levels of exposure needed, for instance if the sky is bright but the ground is dark, the graduated filter would mean you would be able to have both the sky and the ground correctly exposed
- Ultra Violet Filters
Mostly used in areas where the surroundings are bright, for instance a snowy landscape which reflects a lot of light into the camera. It does this by reducing the haze from UV light, this also removes the blue tint you get when taking photographs in these types of environment.
- High Dynamic Range Photography (HDR)
Dynamic range is the difference between the lightest and the darkest part of a photograph. HDR allows for a greater range to be represented than standard display can produce
Below is a few examples of HDR photography I took a while ago (click to enlarge)
