Kelvin L: I'll definitely get on board with a mirrorless system once decent perspective control / tilt-shift lenses start appearing for them. I think the only mirrorless with a kinda-native TS lens is the Canon EOS-M (with adapter).

Good to see Fujifilm acknowledging tilt-shift, even if it's low priority.

As an addendum, this chap's blog post reflects my experiences fairly closely, with regards to not letting go of the technical camera and the generally poor state of small format wide PC/TS solutions: http://tashley1.zenfolio.com/blog/2012/7/the-24mm-pc-e

SirSeth I've been working on a project requiring perspective control and short camera-to-subject distances. Currently the only way I can get some of the images I want are with a 75mm lens on 4x5" field camera (I think equivalent of 24mm focal length on a 35mm camera) on extreme shifts, to the point where I'm running out of bellows.

I've been looking out for a digital solution for a while, and the adapters aren't really an option. Canon 17mm TSE is looking like the best one so far but I would need a camera body to match (Nikon is in the bag right now!). In the meantime the 4x5" is getting the job done, although running to labs + scanning is getting old pretty quickly.

For longer focal lengths I've been thinking about getting one of those Kipon shift adapters so I can use some Pentax 67 lenses lying around on the D800.

Fair point re: adapters, but wide angle tilt shift options with sufficient image circle cover are lacking. Widest to date is Canon 17mm TSE (about 24mm equivalent on APS)

SolidMetal: Can you do this with color film? I heard it was much harder to manipulate because its sensitivity to every form of light.

Looks like Ctein has made his book "Post Exposure" available for free access online, in case you're interested: http://ctein.com/PostExposure2ndIllustrated.pdf

Kelvin L: Microwaving to assess print dry-down was on page 84 of the "The Print", 1983 edition. Not new information to some of us oldtimers.

No worries Carey - it's great to see a new generation of photographers rediscover the history of their chosen interest. There is a wealth of knowledge and experience out there. I hope that the 'new media' of blogging and video streaming acts as a gateway for new emerging artists to explore the knowledge locked away in both printed media (books!) and the life experiences of older practitioners.

Yes it depends on which part you're referring to. Dodging and burning? Yes. Contrast control? Not really. The colour layers in both film and Type C print materials didn't respond equally to time and temperature changes during development. Grain and colour shifts were the problem. It could be done (there was a Ctein article in the old 'Darkroom Photography' magazine during the late '80s on "Color Zone System") but it wasn't practical as it had a very narrow margin of utility.

Eventually a practical colour zone system emerged, and it's called digital photography. Adams had basically laid the groundwork for the contemporary use of histograms with his zone concept.

On article Hands-on with Hasselblad X1D (802 comments in total)
In reply to:

Kelvin L: One thing that's desperately needed in the digital imaging world is a decent wide angle tilt shift solution. Hopefully Hasselblad will develop a modern Arcbody/Flexbody equivalent for the architecture and product photographer that's less clumsy than an Alpa or Sinar - something now possible with the short mount-to-sensor distance.

@Dianoda if I had a Canon TS-E I might as well use a Canon SLR. This Hasselblad body is an opportunity to create a new solution offering view camera movement range (extra large image circle, extreme movement range, and electronic body-lens integration) priced between a Canon setup and full blown Alpa tilt-shift setup - with image quality comparable to the Alpa.

Franka T.L.: I used to do a lot of large format, still occasionally do. I see a couple of issue here. while the aperture control is great, does it have any signal feedback to the camera, also if I read this right, the rear need not always be a canon body ( or am I wrong ).

the other more pressing one is that most lens simply will not have the image circle required to allow for any degree of tilt and shift with reasonably delivered quality in the projected image. That's why we need those big TS-E lens.

What instead I think should be made is some sort of Electronic aperture control plate so we can put on some of the better current medium format lens like Leica S, Pentax 645, Phase One / Mamiya, or Hassy H series.

JP001 that makes sense. 17mm Canon TS-E + APS-C mirrorless + Actus makes a great combination. A shame that this specific lens combination isn't mentioned in Cambo's promo materials.

I agree Franka about the image circle problem. This device would only make sense if you use an APS-C sensor or 4/3. Even then what's the benefit of using an EOS lens over a manual process/enlarger lens or medium format lens?

Kelvin L: I use a 4x5 field camera, and have been constantly on the lookout for an affordable digital alternative with the same lens movement versatility. I like the look of this system (and it's priced sensibly for what it is), but unfortunately it seems more useful for product/macro than location work.

I have a Nikon D800 body, and it seems like Canon is the way to go for a decent range of tilt-shift lenses - a significant investment for a total system swap and 3 TS lenses. Thus the continued use of the Wista field camera.

Sooner or later the 4x5 film supply will dry up and I'll have to take the plunge. Perhaps someone enterprising in Japan (or Kickstarter) can come up with an affordable dedicated wideangle capable flexbody-type digital for the masses - 4/3 format perhaps?

Canon has a 17mm TSE.

Lightzone has been doing this since the beginning. Adobe Bridge also does this with its sidecar XML files.

Kelvin L: I'd definitely be interested in a monochrome digital camera with panchromatic and infrared sensitivity - but in a body with modern features such as autofocus and live view.

I think the trouble may lie in the lack of commodity monochrome sensor suppliers - perhaps the cost of the Leica is partly due to the use of a bespoke low-volume sensor.

Interesting link - I hadn't come across that one before. I'm now curious whether attaching the Colour Filter Array is too tightly integrated into the sensor production to make runs of "no-CFA" chips economically viable. This is different to IR filters, which I assume are simply sheets of glass attached to the top during camera manufacture.
