In case you're still looking at comments from this video: You did mention that many techniques have been discovered. I'm just a little surprised that you left it at "we just have to go back and forth a few times." In my experience, location of the plane of focus can mean the difference between f/22+ and f/45, or a belief that it "can't be done with this lens," i.e., achieving adequate DoF. I have been practicing this myself recently with my 4x5 field camera and a couple of lenses, both tilt and swing. More specifically, I have found the technique of marking the extension difference in mm between fore and back, selecting the center point of travel, and using a table to select the aperture, the most efficient. It tells me right away what my aperture will need to be. It is then that I can try relocating the plane of focus to see if it provides a larger aperture, if the first try yielded, say, f/45. Admittedly, marking the bed of many field cameras is relatively simple; this may not be practical with a rail, press, or other camera. All the best, Philip.
Tony at 8:48 this axial focus technique has another, similar method on the sinars, they have a sheimpflug scale on the focuser a dial which when a near subject is focused, this dial is set at zero, the second far away subject is then focused, the dial setting shows +\- and a number, this is then translated to the swing\ tilt axis the +/- giving the correct direction of motion..... the subjects NOW are focused at the same time (the plane of focus is now adjusted correctly), now just refocus to the optimal point for the scene.
When I take high camera angle shots of boxed food products, the high camera angle results in distortion caused by the rear standard no longer being parallel to the vertical subject lines. Adjusting the rear standard to make it parallel to the vertical subject lines eliminates this distortion. From the high camera angle, I may also need to tilt and/or swing the front standard to control the plane of focus. What tips do you suggest for using front and back standard movements for the same subject?
That's definitely a series of complex movements. I would recommend building one type of movement at a time. For precise work, f you use a high output light source, you could stop down the lens and look on the ground glass if you are getting what you were looking for. Thanks watching! 😎
Thanks for providing practical exercises to practice this technique with clear visual demonstration. Incredibly helpful for us visual and hands on learners 😊
one other focus technique unique to the sinars/Toyo and other monorail modular systems is a binocular finder, a mirror inside a pentagonal p.v.c. box, with a welding goggle piece at one end to view through; this has magnification, and is a great isolator of light, and can be affixed on either ground glass frame, or in the sinar case, on the standards themselves (the bellows frame of the standards is the same size!)- increases the systems' adaptability to shooting scenarios.
My Sinar (and I guess that this is where specific products may differ), tells me to focus on the distant object (using the rear standard), zero the readings on the microfocus wheel and the reading for degree of tilt before then focusing on the near object. This will give me an aperture reading. I use that at the lens and, and then I turn my focus back to a reading of one half of that aperture - i.e; defocusing both of the objects in the ground glass.
Very clear and concise explanation of these techniques. One thing I learned long ago when applying base tilts is to keep my hand on the focus knob and slowly refocus as I move the standard. This avoids the multiple iterations to "get it right."
This was very interesting, and I think i have an idea why my photos are not focused all the way through. I will have to watch this video over and over again in increments. To back up and begin at a very elementary level, when you begin focusing, is your lens wide open? To attain deep focus, much like Ansel Adams, do you suggest (once focused) stopping down to f64? Or a larger aperture. Btw, I have an Intrepid 4x5. Thank you so much.
Hi Michael. I'm glad you are here. I always begin focusing wide open, then I stop down the lens as I'm viewing the ground glass to make sure all the areas I want to be acceptably sharp are good. Have you watched my other video on optimizing aperture. Hope this help. Thanks for watching!
Tony, if you want a lighter sinar camera, Try the F2, a 'Field' version of this monorail system, the function cars (where the knobs are), is a lot lighter in construction- Not that is so light it can't do it's job, it still is strong enough to hold a lens out at 1M+ ( as is customary in the extended condition for macro work), there is even 8x10" rear standards which can be affixed to this monorail if so desired.
When you're wondering why "we needed" tilt/swing in order to change the focused-on plane, it's because your 35mm camera's portrait lens would be ~600mm at 8"*10" and even at f/90 has shallow Depth of Field (DoF). That's why the tilt in the tree/house example is needed to get both sharp. The "Constitution" of focusing is Scheimpflug's Law that says that when the intersection (crossing line) between film plane, focus plane, and lens plane is in one line, then you have a perfect match. This works in the neutral/zero position because of the axiom in geometry that defines that parallel lines/planes cross at infinity. In tilt/swing it really helps to keep Scheimpflug (shime pfloog) in mind.
Tony, Very good! I think Fred Newman's method of iterated focusing to the farthest object and tilting the lens to bring the nearest objects in sharp focus foollwed by stopping the lens to bring the entire scene in sharp focus is simpler and nore interactive than Alex's mathematical method. I want to get your take on the latter method
Hi John. Thanks for watching this video. Have you watched my other video on optimizing aperture? That's where I discuss Alex Burke's method. I appreciate your support.😃
You said "Scheimpflug" the right way - I'm impressed! 😁 A good overview over all of what I would ever need - the moment I get my real lenses operational … (Not having to worry about all this is one appeal of pinhole photography. "Sharpness is a bourgeois concept.", as Henri Cartier-Bresson said.😉)
@@michaelmoss2901 And the exposure to be selected alongside the nice rule best in in our language: Die Sonne lacht Blende acht In English there is the "sunny 16"
An obliging taxiderimst, a very long bamboo stick, some very fine wire, and you're all done. There is a guy who uses a Graflex in the Formula One arena. It works! That brings me back, though, to a former colleague who was a keen photographer and who one day showed me his entries for a club competition. He'd gone to a F3 race, and his photos were triumphs technically. Beautiful composition, fantastic colours, mastery of dynamic range. His pride was a photo of a car passing at high speed. The car was rendered in incredible detail, was almost as clean and defined as if you were looking at the blueprints, and the faces of the crowd could have been used as evidence for identification in a court. It was awful. No sense of movement, no excitement. It looked like a parked car. Hell, the road surface was clear. Too many hours at a screen.
It was a very entertaining video, but to be honest it was way less informative that what Thomas Cristopher Moore uploaded 16 years ago ( Scheimpflug / Plane of focus on RUclips). Still it was fun to watch!

Great video, Tony! It's nice to see what I missed by not going to school for this stuff. :P

Its nice to have that feature built in to your Sinar. Thanks for sharing! I appreciate your support.😀
Nice explanation, I've never really thought about the last part before. But it makes sense when you think about it.
Thank you my friend! I appreciate your support. 😎
