    I didn't demonstrate that. You shouldn't accuse people of cheating based on nothing.

    Perhaps you are not aware but the world for me does not revolve around American spelling :-D

    Where I live when used as a noun it is "practice" and when used as a verb, as it was in my sentence, it is "practise" :-)

    Then, as a writer of real English, it would have been better to write "if you were to practise", assuming that your schooling included English grammar.

    That is your opinion as is your right to have.

    What I wrote conveyed the meaning and context correctly.

    In any case you are continuing to prove my point that you are the type of person who does not practise what they preach, so I don't take you seriously.

    You suggest to people to not reply to my posts and then you make a fool of yourself by continuing to do so. How dumb is that? lol :-D

    And here you are yet again with your inimitably rude and confrontational style!

    At one time in the era of the Exposure Triangle diatribe I was 100% on your side vs. the others - but expect no more support from me, now that you have made it very personal with that last sentence.

    I await your next pathetic attempt at the coveted thread-winning Last Word.

    I told him so, he prefers to ignore it. Maybe he was tricked by zebras or histogram. Anyway, he dialed -0.3 EV EC.
    Also, this isn't raw, this is lossy:

    f/4 wouldn't be my choice either.

    no its not its perfectly exposed.

    Your definition of exposure is different to Jim's.

    Your definition of exposure is how dark or light a photo looks on the medium it is being viewed on. That is actually image lightness not exposure.

    Exposure is the amount of light that struck the sensor per unit area while the shutter was open.

    A lot more light could have been put onto the sensor without clipping the raw data.

    I took the image and its how i wanted to expose the image. so its perfect. Jim has yet to enter the comparrision and post a converted raw thats better than the jpeg. and Btw you havnt either. 😉

    According to Sony's own raw converter you clipped the shadows.
