This is a masterpiece, the photograph which appears not to be of a good quality are in fact a good principle of practice to to look at different texture, age, different height, colour, structures and with the different clothes of the gender, welcome to the real world!! When I began to treat patients my professors always asked all the students to change the partner or clients to have a different touch, texture of the skin, different build up., so you may test the dysfunction from a different point of view so that is the principle of the photographs, to appreciate the dysfunction in different contexts. That is not a drawing....real life, real cases.
This is a real tool, not only a reading book, it is also a consultation book, which solves the problem of any doubts if not a second test if not more...extensive of course but complete research, peace of mind for the clear whole picture and also when the client has to come for a second session or for the Doctor, or consultant to be in charge! Also for the student who wants to know the latest or some parts very clear, be the best. This is a must.
