TLR B&W Conversion is an Adobe Photoshop Lightroom 2 presets for making high contrast, Ansel Adam's like B&W images from a color image.
The Quick B&W presets simulate the use of color filters with B&W film. There are also Quick B&W actions for special purposes, like simulating panchromatic and orthochromatic film.
Quick B&W High Contrast presets make high contrast B&W conversions with three settings to choose from.
Duotones, tritones, and quadtones use spot color inks and multiple passes on a printer. They are expensive to produce because of the separate plates and press washes. Photoshop has a duotone mode. Printing these images on an inkjet printer results in a pseudo-duotone. These can be very lovely images and nearly indistinguishable from a true duo/tri/quadtone.
If all you want to do is produce a toned B&W print, there is no need to use Photoshop to convert your image to Duotone mode. You can use the TLR B&W Split Toning ACR Presets instead and give your RAW files a fine art tone.
TLR Cross-Processing Lightroom Presets applies colored overlay effects to your images that simulate the interesting artistic effects that film photographers achieve by cross-processing color film (i.e., processing color negative film with color slide film chemicals or using color negative film chemicals to process color slide film).
For even more creative possibilities, a wide range of color filter effects are available for the film cross-processing effects.
