Nikon Coolpix P7800 review – Dynamic range
Image: Using the supplied Nikon Raw software, I was able to pull back a lot more detail in the highlight areas to create a better image
The sensor in the P7800 is a 1/1.7in unit that, at 7.6×5.7mm, is bigger than the typical 1/2.3in sensor (6.17×4.55mm) found in most consumer compacts. It is, however, smaller than the APS-C (23.6×15.6mm) or 1in-type (12.8×9.6mm) sensors we have seen in many recent premium compacts. The dynamic range is good considering the sensor size. However, highlight detail is often lost in JPEGs, although some can be salvaged from the corresponding raw files.
I found that not much shadow detail is lost and even in very dark areas information can be brought back in Photoshop or using the supplied Nikon raw software. Also, with the active D-Lighting feature turned on, a decent level of detail can be lifted from the shadow areas in-camera. To achieve the best results with D-Lighting, I had to marginally underexpose the images to maximise the dynamic range appearance. However, using this function at higher ISO sensitivities means noise is present in certain areas and appears smudgy with less detail.
