When textiles are coloured black, this is achieved by a high degree of colour saturation. To do so, highly concentrated magenta (dark violet), blue black, or brown red is use in the colouring baths. Especially in the case of modern synthetic fabrics such as polyamide, polyester, and polyurethane
compounds a true black colouring involves enormous problems. Due to the human eye’s imperfection the viewer registers these colours as black – even though it is only e.g. deep dark violet. Under incandescent lighting especially, these fabrics do not appear black, but rather display a distinct colour shift towards violet or also brown violet. As a result of its above-average sensitivity for infrared light, the LEICA M8 “sees” these “red” fabrics quite intensely.
In winter indoor shots under incandescent light are more common. Since these light sources have a stronger infrared proportion, the annoying effect of black colours reproduced in magenta can be expected more often. In spring and summer there are stronger IR reflections from the chlorophyll in green vegetation.
This can lead to a yellowish
If you intend to do B/W photography with your Leica M8, the camera’s increased infrared sensitivity does not come into effect. Only synthetic black fabrics are rendered slightly brighter than they appear to the eye. This phenomenon was not considered to be important in any of the investigated cases.
The LEICA M8 takes approx. 1 second to power up. It takes approx. 3-4 seconds to read the SD card completely. If the shutter is released before the card is read completely, information on the card is not accessible. In such cases the automatically replayed image will be referred to as number 0/0, but, when the camera is switched to permanent reviewing, the camera will show the correct image number.
From firmware version 1.201, greatly improved algorithms for the automatic white balance have been integrated. This improvement allows colour-neutral images under almost all lighting conditions. In comparison to former firmware versions, the writing time will be slightly longer (approx. +1.3 seconds with „fast“ cards), if JPG or DNG+JPG was chosen as the output format. If images are taken in the DNG format, the writing time will remain unchanged.
