ongoponton asked: Hey Toni i saw the sections of Christopher James book and Christina Andersons book that included you.i found you on medium and read all of your posts. I am just doing some tricolor tests usually jump right in to the most complicated and work backwards. I just had a question about your digital step wedges did you custom make these or are they available online someplace?
I make my own step wedges. Send me an email at gonoma@mac.com and I can email you the wedges I’m using

paulivanushkaphotography-blog asked: when working with cmyk print, at what point in time do i change my finished file to cmyk? or do work post prod in cmyk if iam going to mske a cmyk gum print?
I only use RGB, but if your going to make CMYK negs, I think perhaps you should work in CMYK mode from the start or better yet convert to CMYK right before you Multichannel.
