I believe PP is OK. It offers the chance to improve/express one's fotos.
I got my first SLR (Konica A1(?)) In the late 1960's. 1968 probably. I went Digital in the late 1990's with a Sony Mavica. Then around 2000 I upgraded to a Canon Rebel. Since then, I have had a 40D, 50D, and curently use a Canon 5D.
I have it and am happy wiht it. I think it will help any beginning Photographer. It is good that he strongly encourages students to practice.
