Hi Marcel,
Not to harsh at all, I do agree with you about having to learn this myself, as it was my choice to take it up, I just wanted my pictures to be perfect first time round but then i suppose there would be no fun or frustration in my learning curve. I think im just struggling with the relationship between aperture/shutter speed/ISO etc, and the fact that sometimes when I am taking a picture with my 18-55mm lense on and the subject doesnt come into focus and this frustrates me as i have kept the settings the same and only pressed shoot??
