If you are using Photoshop, there are several ways to convert from RGB to grayscale.
1- Direct conversion to Greyscale. Avoid. It is based on luminosity of the image. A conversion based on luminance would give better result. 2- Desaturate method. Then use levels and curve to control contrast and density. 3- Convert to Lab Color then delete individual channels. A good method 4- Channel Mixer method, probably the preferred method 5- Calculation method (Image - Calculation - Multiply, try other settings too) There could be others methods in Photoshop that I do not know about.
