Tilt shift for dummies
- Thread starter Quasimodo
- Start date
Having read and not understanding the Scheimpflug principle on wikipedia, with its dense and mathematical language; I came over some great articles written by Harold Merklinger. Imo he writes in a pedagogical and clear manner explaining the principle.

80% BY HEART, 15% BY LENSES AND ONLY 5% BY CAMERA

Dear Friend , NWPhil.
The Bull eye target picture( From My BB-Gun Target Practice) , 1- I put at he back of Camera to show the Location of Sensor in the Camera, 3- of the Bull eye targets the Center is show of the Center Location of the Real Photo= at the Right Focus, The Left Bull eye target is show the Tilt of Lens toward the camera sensor( When I tilt the Lens to the Left position) = Make the Left side Details of Photos = Blur, The Right Bull eye target that show on the photo = move toward the front of the camera, or far away from the sensor, compare with the center bull eye position= that make the right side of the picture are blur. That how to change the DOF in both side of the Photo, and leave the center is only area is sharp.
Yes, I use this method to show to my Photography/ Camera club, to show them , how it work.
Here is a great Video that I adapt for my class
Using a Tilt Shift Lens: Ep 204: Digital Photography 1 on 1
Enjoy

Your camera comes with an indicator for that, showing where the film/sensor plane is within the camera:
Look for that symbol similar to the greek letter phi:
Φ
the line indicates the plane through the camera
The 5D cameras have that symbol on the left of the viewfinder box, near the mode dial.

The book you want is:
"Using the View Camera - A Creative Guide to Large Format Photography" (Revised Edition)
by Steve Simmons
Amphoto Books
ISBN 0-8174-6353-4 (pbk)
It's a comprehensive guide to using view cameras, but then of course the principles are exactly the same as are involved in the use of tilt-shift lenses. This book will answer all of your questions, comprehensively, without getting excessively involved in the mathematical theory and it's very readable. You can ignore the bits about film. The only thing it won't tell you is not to tighten the locking knobs on Canon's TS-E lenses too much. They're easy to break and expensive (very) to fix.

Thanks a lot
I will get it soon. Nice of you also to point out that one should not tighten the locking screw too hard. I think that I might have, but luckily nothing has broken yet....

Late to the party here, and I don't shoot T/S, but I did find this recent T/S video from the RokiBowYang camp quite interesting:
Samyang Tilt-Shift 24mm f/3.5 in action
Lots of examples. The idea of using T/S to keep a large depth of field in focus (albeit in a line) without having to stop down or composite multiple shots was pretty cool. (See 6:18 - 7:10).

Better late than not attending at all
I will look at the video tomorrow as it is 12.30 am here now, and the kids show no mercy when it comes to sleeping habits appropriate for weekends

The entirety of what you need to understand is encapsulated in the two gif's on the page I linked to originally.
Scheimpflug is only half the interesting bit, and his work has little relevance to us, he was only interested in huge J point distances that require very little tilt. His work was for battlefield imagery from balloons in the first world war.
Merklinger, and his J point/hinge line, are the really interesting bits for us and nothing explains this half as well as the gif does.
If you want a deeper understanding of the maths then Merklinger's free ebook, and lets not forget he actually wrote the book on this, is available here http://www.cs.cmu.edu/~ILIM/courses/vision-sensors/readings/FVC16.pdf
His other work, on depth of field for tilted images, is available entirely free too, here, http://www.trenholm.org/hmmerk/TIAOOFe.pdf
You do not need to buy anything to have the deepest understanding of tilt and shift use.

Sorry, haven't read the whole thread, but from my perspective, Darwin Wiggett's ebook on TS was particularly helpful for me:

Thanks
Surapon and others have suggested the book also in other treads here on TS. It looks good, but primarly on landscape, and not on other areas that I would like to explore.

I'm not intending to be confrontational at all, but I found the Darwin ebook ("The Tilt-Shift Lens Advantage for Outdoor & Nature Photography") to be a complete waste of $20... It's overly simplistic and too full of "pretty pictures"... But my biggest problem with this book is with regards to his approach to finding the correct "balance" between lens-tilt & focus to achieve the "infinite depth-of-field effect" that most beginning tilt-shift-photographers struggle with... His technique of "bend (tilt) for background, [and then] focus for foreground" is the exact opposite way everyone else does it; and his insistence that "if you mix these up, you’ll likely never find optimal tilt" is just flat-out wrong...
A quick Google-search will show that everyone else tells you to "focus for the background & tilt for the foreground." It really isn't difficult at all to find the correct "balance" between lens-tilt & focus to get the "infinite depth-of-field effect." It's just really hard to try to explain to someone who hasn't spent an afternoon playing around (experimenting/practicing) with a TS lens. Those animated gif's referred to by privatebydesign (over at northlight-images http://www.northlight-images.co.uk/article_pages/using_tilt.html) are a great way to get your head around the whole tilt vs focus thing... And once you're comfortable with the idea of balancing tilt & focus, a great short-cut (that I use all the time) is described here: http://www.northlight-images.co.uk/article_pages/focus-with-tilt.html.
