False colors and moiré patterns can appear in images when shooting repetitive patterns. Moiré is nothing new. It was well known that Nikon D70, the first consumer DSLR camera from Nikon, produces moiré pattern easily due to a weak anti-aliasing filter in front of the image sensor. The recently announced D800E removes the “effect” of the anti-aliasing filter, which results in a small gain in sharpness and resolution but carries an increased chance of false color and moiré.

One benefit of shooting RAW image is that RAW photo editors do not change the RAW image data but only save or embed the editing information along with the image data. When the edited RAW photo is opened in the editing software later, the software re-renders the image using the original image data and the stored editing information. As a result you can mess with a RAW photo and go back to the original without any loss of image information. This is not the case for JPEG photos. Each time a JPEG file is modified and saved the image data is permanently altered. Since image data is saved in 8-bit per color format and lousy compression algorithm is used to reduce the file size, image data can be permanently lost. Read More…
