Annoying it is unfortunately sometimes in detail, because the author speaks first times very slowly and explained so fussy and with permanent reps that I will regularly impatient and think 'come to the point!'
Example demonstrations he leads but then again so unclean that, as a newcomer I can not say whether the result due to its operation as 'bad', or whether this is actually achieved for Photoshop the limits of feasibility. (Eg section 3.12 - What would he have done as a professional with the bottom corner to get a satisfactory result He can then just so ... And what I do in such a case? - Sure, it comes to an overview but also there I have to work cleanly, so that the user learns what works and what does not).
And a second star deduction is based in detail but often poorly executed statements. eg the chapter levels. Instead of beginning to say clearly what levels and what are they for once, he's talking about a very long time just about the "levels a basic technology of PS" and then goes directly to tell me where I find them in PS. '4.2 What are levels?' answered this very question just not really, so that I can do as a novice a basic and simple idea to Wes it's here ... This I can then open up everything somehow from the context of the demonstrations, but well explained what I call the not.
