Try this or this. This one is my favorite because the examples are a photo of a very hot naked chick...er *cough*...I mean uh, "fine art nude". If you want to get technical, I think the normal formula for converting color to greyscale is 30% red, 59% green, and 11% blue (approximately). This attempts to correct for how the eye unevenly processes different light wavelengths. But your probably going to want to apply custom values to get it how you want. I'd start by converting to L*a*b mode, disable the a* and b* channels, then use Curves or Levels on L to tweak contrast (this is a quick and dirty method but can yield nice results with a minimum of hassle).debroglie said:I have to convert the scan of a painting to greyscale for printing. What is the best way to go about this in photoshop. If you could give me examples of what it would look like, that'd be great!
I know the simple way to convert to grayscale in photoshop, but I was wondering if there is an ideal way to do it to preserve the subtlties and nuances of the color version. Is there one technique that produces a more vibrant result? I will be printing this in a college literary magazine, and our budget doesn't allow for it to be color.mkrishnan said:A second way to do it is to choose Enhance->Adjust Color->Remove Color, but this produces visually identical results. Both literally go to grayscale. You can also use the color variations tool in that segment to produce things like sepia tones. Can you say more about what you want to accomplish? Are you just trying to take it to a printing service and you want a large b&w version? Or are you trying to print it at home (in which case I don't even think you gain anything by making the pic b&w)? Or are you trying for an artistic effect?
