Developing a tilt/shift system for 35mm digital camera based on 4x5 large format view

John,
Thank you, well explained.
Alex

Woah! I'm totally impressed! Thanks for sharing the rig setup!

I've got some test images from the camera, with Rodenstock APO Rodagon N 80 F4 attached:
Fixed exposure on both, 1/250 F8
Non tilted, straight photo:

Hah, my friend at work and I were just talking about this. Was going to get some bellows for my canon or his ep-1. Then mod them a little so they could tilt and shift and use his 4x5 lenses on them for fun!

I've got some more real life examples using my tilt-shift system:

See how i've got the whole bracelet in a focus:

Very nice Alex. I read your post on blog describing the setup. Very helpful. Let me ask: is it possible to use extension tubes on a Canon TS-E lens (say the 90mm) to combine macro work with T/S to achieve a wider simulated DOF? Your 4X5 view camera setup with a Canon body is quite impressive but a bit out of reach for me.

Peter,
I can't be 100% sure, as I never tried using such setup, but here is my thoughts: you'll be able to use extension tube, but you'll limited tilt-shift capability, as a lens projecting circle will be out of sensor very soon.
Even if Canon would have a macro tilt shift, it won't be able to match view camera tilt angles. Few days ago I've played with Hasselblad H3 camera with a tilt-shift adapter (http://www.hasselbladu​sa.com …lt-and-shift-adapter.aspx) and it was not able to get the whole bracelet in a focus because of the adapter limitations.
Soon I'll post a video, where will be shown actual tilt angle on my adapter for this shot, and you'll see how huge it was.

Another thing you could do is set up a slider so you could move the EOS body up/down and left/right to cover the whole field of view of the large format lens, say with 9 or 16 overlapping images. Then stitch the overlapping images with software e.g. Photoshop or Autopano Pro.

Then you'd have large format definition too. Static subjects only of course.

Again, not to take away from Alex's acheivement, but anyone with experience with focus-stacking software want to chime in? (Taking multiple images and combining them to acheive greater apparent DOF? Anyone use CS4 for this?)

Impressive samples! That bracelet is so crisp and sharp. I can almost touch it.

Peter,
I've read about such software, hope to find it and post a link here. It did not work for me ( the idea), as there will be too much post-production efforts when shooting hundreds of pieces,(for a catalog, for example).

Puttick, with view camera setup there are same movements for back frame, where the camera is mounted. You can get 60+ megapixel stitched photo from it.. But it won't help with the focus tilt..

Tilt Shift and focus stacking are not the same and not really comparable. With tilt shift you can still get pleasingly narrow depth of field, just along a path that isn't parallel to the image plane. With focus stacking, you'd lose that control. Focus stacking is basically an artificial ultra-narrow aperture, unless you spent days post processing the shots, you'd never get the results a tilt shift can do with one click.

Eventually got a video from that photoshoot:

You can see there how much tilted the lens was.. can't do it with any existing tilt-shift adapters on a market.

Nice Alex - thanks for posting that. Man, it's one ugly camera rig you got there, but quite effective.

Also, I've been using canned air to blow dust, but it never seems to get all of it. I'm going to try your brush technique.

I haven't really shot any jewelry, but you can see some of my product stuff here: www.greatproductshots.​com

Peter,
You've got a great portfolio! Thanks for sharing here.
The brush I use is actually a sensor brush, it charges with static electricity to attract dust. I did not work well with a sensor, but great for a products like these.

Ugly camera? Man, my baby is beautiful :
