Most of my images are post processed as monochrome. In other words they have been captured in the RAW format and then have been edited by a post processing tool to achieve the monochrome effect. An image is considered to be Monochrome only if it gives the impression of having no color (i.e. it contains only shades of grey which can include pure black and pure white); OR it gives the impression of being a greyscale image that has been toned in one color across the entire image. Aditionally some of my images will be mainly monochrome but with a single dominant colour displayed.
Visible light ranges from 400 nm (violet/blue) to 700 nm (deep red). Wavelengths above 700 nm and up to about 5000 nm are known as near infrared. Some images have been captured by an Infrared converted camera and then converted to monochrome. Whilst others have been captured in RAW with the focus on lines, textures and shadows. The difference with the IR photo is that foliage will appear white and skys will appear dark. I tend to prefer to convert my IR images to monochrome but occasionally I will use a post processing technique known as colour channel mixing to produce false colours - these images will be displayed in my general photography gallery.
