    Precisely. In order for one to offer viewers of photographs all scene elements that could have been scanned and examined in detail by a human present when they were made, they must be sharp everywhere.

    Yup. And if one wishes to make a photograph that's soft focus, do that. Either is perfectly valid and neither conflicts with anything I wrote.

    I hope to have some example images shot on 14x17 with the 24" lens that Tri has developed. My last shoot I had a film problem. I'll post some images as soon as I can.

    The pictures look great. Apertures used for the photos would be helpful. Perhaps you stated that earlier, but it would still be useful with each picture so as not to have to reread.

    Corrected. Thanks for reminding me.
    I normally exposed without the light meter then developed the negatives by inspection.

    I would love to see you compare your signature lens to a Struss Pictorial lens?
    Funny I had the same observations except for precisely opposite A vs B prints; B looks swirley to me and sharper in the centre.
