About 3 months ago I bought a camera with Live View. Couldn't see the point to start with really, then last week it dawned on me that for folk brought up on MF and LF, its actually just like composing your picture on the ground glass. Fantastic, now I'm hooked.
Obviously for purists, its not upside down or back to front yet, but these new ones with articulating screens should soon fix that! On the other hand never needed to resort to the Gaussian Blur filter with 5x4.
