    When will the doh`s end?

    Lately I have been cursing at my 150mm f/5.6 Fujinon-W for it`s small image circle, not allowing almost any front tilt before vignetting.Not always easy to see this on the groundglass, so I ended up with a bunch of lousy negs because of this.
    I was halfway ready to buy a 150mm Sironar-S to get over this..Then it came to me, I`ve alwasy had this rubber lenshood on it, quite large actually, the type that can extend to three different lengths.. So... I pushed it a notch deeper, and my tilt was back! Doh.........
    I can`t imagine the Sironar-S can be much sharper than this little Fujinon, it`s super-sharp even wide open.

    I`m still amazed by the number of mistakes it possible to do with LF, just when you though you had done them all....

    My experience has been that the number of potential mistakes and the number of opportunities in a given system are approximately equal. Build a system with a small number of potential mistakes (incorrectly referred to as "foolproofing", which in fact merely reminds you how resourceful fools really are), and there are a similarly small number of ways to use the system well. Build a system (like a well made large format camera) with many ways to use it well, and there will be a plethora of ways to screw up with it.

    The process of reducing mistakes and increasing successful use of systems is called "learning."
    Photography has always fascinated me -- as a child, simply for the magic of capturing an image onto glossy paper with a little box, but as an adult because of the unique juxtaposition of science and art -- the physics of optics, the mechanics of the camera, the chemistry of film and developer, alongside the art in seeing, composing, exposing, processing and printing.

    Front tilt eats up lens coverage faster then any other movement. The reason that this is so is that when front tilt is used the plane of the image circle becomes the hypotenuse of a right triangle.

    Blix, Funny story to be sure. Thanks for sharing. Isn't reassuring to know that LF offers a whole new world of exquisite opportunities to screw up? My most favored way of messing up a perfectly good sheet of LF film is to pull the darkslide while the shutter is still open....

    Or to open the shutter back up after the exposure before replacing the dark slide and removing the film holder

    Did this once yesterday.

    Try QuickLoads - its pretty obvious when the slide it out... then again, that can be overlooked as well.

    How about forgetting to cycle a grafmatic shut before pulling it from the camera? Argh!

    I have a 250mm Fujinon f/6.7 on my way, for use on both 4x5 and 8x10.
    I guess the 398mm image circle will be enough for some front tilt on my 4x5..

    My best "groaner" is when I pulled the dark slide off the BACK film instead of the one facing the lens. Talk about "DOH!" :rolleyes:

    cheers
