White balance can be a subjective choice in night photography. Removing all color casts may not be the ideal solution for a photograph, and in the case of mixed lighting situations, it may not be practical. Having the flexibility to tweak the white balance in postprocessing reiterates the need to shoot RAW images. Changing the white balance setting can completely change the mood of an image. Most of the time, there isn't a right or wrong white balance. There is a wide range that will give varying effects. m i n i m i z i n g n o i S e at t h e S o u r c e Noise is unwanted information. It is a by-product of electrical processes that receive or transmit signals. Noise can have several sources and is present in all images to some degree. It can be independent of the image and therefore relatively easy to separate and remove, or it can be integral to the image, which makes it harder to deal with. Noise generally detracts from the image quality, but a small amount of noise can enhance apparent sharpness in a photograph. The best way to minimize noise is to eliminate it at the source. There are five key ways to minimize noise in night photographs. In the real world, you won't be able to use all of them, but if you are aware of the sources of noise, you can take measures to minimize it. The main contributors to noise are the following: · Small sensors: A full-frame sensor adds considerably to the cost of a DSLR, but it offers several distinct advantages, including noticeably less noise than cropped APS-C sensors. Although full-
