There is a certain point here and there's certainly a huge crossover between engineers and photographers (and also knitters, but that's another story).
You need to develop both technical skills and an artistic vision. Engineers by their nature, tend to focus on the first and neglect the latter. There are some great book on the artistic side, but I particularly "Vision and Voice: Refining Your Vision in Adobe Photoshop Lightroom" by David duChemin[1]. This is most definitely not a book about Lightroom but rather about your artistic intent which starts when you first think of the shot and how you carry that "vision" through to Lightroom and express with your post-processing "voice". The discussion are priceless and it works as a book even if you don't use Lightroom. His other books and ebooks are also very good.
