I want to send Black and White files to a local lab for making neural b/w C-prints. When I asked them the type of file format etc. to provide them for best results this is what they said:
"To get a neutral BW image, convert the image to grayscale first. Then they can convert to a color profile such as sRGB using Relative Colorimetric intent. This will achieve true BW based on the white point of the paper."
Can anyone break this process down for me in detailed, but, layman's terms?
