Totally new to photography? Iif so,, start with Auto mode, and focus on composition, holding the camera steady, make a conscious effort to support the camera well, hold breath, snap, More shots are ruined due to unnessary haste, hence the slogan,,
haste makes waste.
And the D7000 is the perfect starter camera because you can start full auto, and work up to full manual, and not outgrow the camera.
