Digital Camera Dynamic Range - an Investigation Technology Articles | February 6 Adidas Yeezy Boost 350 V2 Black Red UK , 2009
An investigation into the dynamic range of several selected digital SLR cameras including the Nikon D100, Nikon D2x and Canon D20.


Many digital camera sensors have a depth of 12 bits per colour. The bit depth defines the dynamic range of the camera. However, it is difficult to find any recommendation by any of the camera manufacturers that we should be using all 12 bits by working with 16 bit rather than 8 bit files. In addition, many of the features of image processing software (such as Photoshop) do not support the 16 bit mode as they may only be used in 8 bit mode. Potentially Adidas Ultra Boost Blue Men's UK , the result of using the 8 bit mode, which causes 4 bits of information to be thrown away, is that the dynamic range of the camera is reduced and information is lost.

To overcome this problem, many photographers process their work in 12 bit Raw format Adidas Ultra Boost Red Men's UK , converting to 16 bit tif when the final result is to be printed. This method of working is detrimental to workflow as it precludes the use of many of Photoshop's most useful features.

As support for the 16 bit mode by the manufacturers is half hearted to say the least, there is a suspicion that the 4 bits, that are lost when working in 8 bit mode, do not contain any coherent data; they contain only noise. It is also possible that the 4 bits are partially swamped by noise i.e. the higher order bits of the four contain coherent data whilst the lower order bits contain noise.


The following method was used to investigate whether the 4 'lost' bits contain any coherent data. The method involves placing a marker in the image. This provides an easier method of locating the corresponding data addresses in the 8 bit and 16 bit versions of the files Adidas Ultra Boost Pink Women's UK , than by hand calculating the data addresses.

As the 4 bits of interest are most likely to contain coherent data at the camera's lowest sensitivity, the sensitivity was initially set to ISO 100. The effects of raising the sensitivity to ISO 400, ISO 800 and ISO 3200 was tried in later tests.

Everyone in the world desires a peaceful home to come home to. It is hard to imagine what you would do if you did not have a house to go back to at the end of the day. No matter how big or small, people feel most comfortable in their own home. .
