Thanks for following up on my lead, Keith. Your demonstrations helped me understand of what tilt and shift gives us, and what future possibilities might appear on the market some day.

And thanks for asking too!

The Mamiya Press had a tilting back. I used this camera in the 80s.I even had the 250mm f5 which was a beast. I rarely used the tilting back as it was too clunky in operation.

That's not one I've come across - sounds interesting to use - thanks

@@KeithCooper The lenses they produced for this camera were some of the sharpest I have ever used especially the wide angle ones. There are some examples on Flickr.

Another good video Keith

Essentials in my office with my difficulty in close focusing ;-)

Thanks for the info. I was especially interested in your book, which I've ordered!

Thanks - Hope you enjoy it!

When I was a small child in the 1970s, I was worried about the question - How does he divide my image into 6 ID cards? The photographer was moving something on his large-format wooden camera. I thought it was dividing me into 6 images. How funny it is to remember today.

I've seen similar plate holder on a view camera used for police mug shots

Maybe the idea is to tilt the plane of focus fast, then merge it using AI to get an image that is taken with long lens and fast aperture, but still has very deep depth of field. I bet that would be handy with security cameras, and also could allow changing the focus point from the RAW image data and selecting what ever depth of field in post editing. Or maybe tell it what depth of field you want, without changing aperture. That sort of system also might not require similar focusing system or it being as accurate than normal cameras. Could be handy for all sorts of stuff, not just photos but also video. Or maybe i just didnt understand the whole thing properly.

Changing focus after capture would be similar to plenoptic or light field cameras. If you read the patents there are a lot of diagrams showing the plane of focus looking along a street. The mechanisms for the internal shift/tilt are similar to lens IS units - so of similar speed. As to security stuff, merging it with AI could well cause evidentiary concerns if the resulting video was used in court [obviously depends on where you are]

The sports photography applications got me interested. Just earlier today I was photographing the Finnish Cross Country Running Championships. The possibilities of such lenses/sensors get me hopeful we might someday see a product like that.

Yes - quite a few of the patents have quite long focal length examples. Not for the sorts of shots I tend to use shift with.

Wildlife and particularly birds too, I would think.

Super video - thanks! People on the street coming up to you asking to explain what you're doing with that view camera is akin to one of my favourite scenes from one my all time favourite movies ;) kzread.info/dash/bejne/qoaruquPYLGwj8Y.html

Thanks Yes - that one definitely works for me too ;-)
