I've been through this book thoroughly now and have been spending time practising all the techniques. I feel like I know the content well enough, and it has given me a great foundation.
But where to go now? I have been through most of the content here on Lowepost, which has also helped a lot, but now I guess I am looking for more insight into: the practicalities of the craft; the real-world processes of professional colourists; intermediate and advanced techniques; grading sessions; useful (colour?) theory from related disciplines and art forms; etc.,
Any tips, particularly on which video tutorial sites are best, would be gratefully received.
