    OMG!! _Finally_ , a clear, concise and _logical_ explanation of what The Scheimpflug principle is and the practical application to large format camera movements.
    I just invested in my first 4x5 camera and have been a bit confused about how, exactly, to get the images that I want. This is tremendously helpful. The diagrams alone are worth the price of admission!
    Huge thanks.

    Your explanation is much better than the one offered by a reputable art school I graduated from.

    This is the best scheimpflug explanation in TH-cam. THANK YOU!! Please do more large format camera lecture!!

    Thank you for your video. It's most refreshing. Might I add that architectural, catalog, studio, table top, and food photogs use the Scheimflug principle all day long as well. Excessive F-stops do not always do the job and even counteract the optimal sharpness of the lens. This might be beyond the class lecture and beyond the explanation of the intersection of the 3 planes, but I would be interested if you would explain why the Scheimflug principle works? Thank you for your attention.

    Thank you for this great explanation! I am getting into medium format digital backs and trying to learn more about which cameras to pair them with. I've shot DSLR/mirrorless full frame bodies for 12 years and haven't had a formal education so I never heard about the Scheimfplug principle! Thank you so much!
    I now think I need to get a camera that has tilt and shift since I mainly shoot landscape! Thanks!

      You are going to love the view camera! For landscape, having tilt on the front standard is very useful. You can achieve the same results from a rear tilt, but I feel it's easier from the front.

    This is a great intuitive primer on this principal! Thanks for posting! (I appreciate that there is no math--even though I do love math!). :)

    why tilt rear standard for near object and tilt front standard for far object ? why not use rear standard for both, I am sure there will be configuration of rear standard that brings both object in focus ?

    • @PhotoTeacherBlog

      I use the rear standard to focus without any tilting, then I use the front standard to control the alignment of the focus. I find this easiest, bou can either standard. The part that matters is having the standards aligned so that the planes converge.

    Thank you for this excellent explanation of the Scheimfplug rule. I am new (ish) to large format and would appreciate any information you might have on workshops available in the United States (preferably in the west). Thank you!

      Wow, thanks for the generous feedback! If you are near SF, my course is offered in Fall semester at CCSF. It's pretty fun, also challenging work.
      I'm trying to produce more videos, but it takes time and I have so much other work to tend to right now. Try Simmons or Stone for good textbooks on view camera.

    Anyone know if you need/can use tilt to get near and far in focus, if you have used swing to change the focus plane already ?

    • @PhotoTeacherBlog
      @PhotoTeacherBlog  3 ปีที่แล้ว +2

      Yes you can! You can use both vertical and horizontal movements at the same time. Sometimes it gets difficult if the bellows are close together, so a bag bellows may be helpful.

    FYI this is not the "only" way to get everything in focus. You could of course use digital manipulation with what's called FOCUS STACKING.
    While you could replicate the effects of tilts and swings with focus stacking, note that the view camera is limited in that focus is always on a plane.
    Another limitation of course is that this process is quite convoluted with many variables to change, whereas focus stacking only uses one. This is particularly helpful when the Mars Rover takes pictures for example.
    Finally in certain cases a small aperture cannot be used. In most cases tilts / swings are also impractical such as with microscope cameras so focus stacking is a real life saver.
    That being said, I enjoy using a view camera and have only used focus stacking on rare occasions. I just wanted to correct the statement that tilts/swings are the only way to get everything in focus.

    • @PhotoTeacherBlog

      Focus stacking is a digital method that stitches together multiple digital images. It can create a pretty convincing illusion, but isn't true focus. It's still good enough for most consumers. It's not as useful for a moving subject or for a large format film camera.

    Probably a wonderfully informative video but the audio level is atrocious, why even publish?

    • @PhotoTeacherBlog

      This was a live lecture in a large lecture hall. I publish for the students of my class to review. All are welcome to join this virtual lecture.
