Hasselblad 907X "system"

With announced (as of June 2019) CFV II 50C digital back and the 907X body, Hasselblad made a cool & clever move. A digital back both for old V bodies and for a new "minimal" body - the 907x - bringing X lenses full compatibility.


Bridge the past and the present with the modernized CFV II 50C attached to a classic Hasselblad V System camera. [or] Merge the CFV II 50C with the 907X to create a whole new combination that enables shooting with a variety of Hasselblad optics, ranging from the V System to our modern XCD Lenses.
When combined with the 907X camera body, the photographer gains access to the entire XCD Lens range, providing autofocus and autoexposure.
A high frame rate of 60fps enables a smooth live view through the digital display. Thanks to the high-resolution screen and improved live view, including focus peaking,
the CFV II 50C and 907X combination give access to excellent wide-angle lenses including the XCD 21 and 30. This combination becomes very reminiscent of the Hasselblad SWC camera, but with interchangeable lenses. All HC/HCD, V System, and XPan Lenses can also be used when coupled with the XH Adapter, XV Adapter, and XPan Lens Adapter, respectively.

Battery is now inside CFV body, which has a flip high resolution LCD screen (= waist level electronic "finder").
As their updated X1D II 50C camera (with same ~"old" 50mpx Sony 44x33mm IMX161AQP-C cmos sensor) is <6000$ one can hope that CFV II 50c could be quite cheap (for a new MF back). With the extra handle, would make a super compact / light / cute highly-cropped-medium format camera.

This also means that the Hasselblad V system is still ~alive: Future CFV upgrades will surely include newer Sony 44x33 sensors (e.g. BSI IMX461 100Mpx that will be used in Fujifilm GFX 100, ?with on-chip phase detection = better auto-focus?)... Larger sensor 53.7x40.4mm (e.g. IMX211) are less likely to be used as 'would be ok with V (and H) lenses, but too large for (actual) X lenses on 907x body.

Tableau vivant (staged photography)

Tableau vivant was an approach to picture-making taken up by pioneers of early fine art photography
Today, the approach is exemplified by fine art photographers and artists such as Justine Kurland, Roger Ballen, Jan Saudek, Sandy Skoglund, and Gregory Crewdson...

Radioactive Cats (©Sandy Skoglund, 1980), from

It is sometimes called "staged photography," but this is an imprecise term - since the simple posing of fashion models in the street is also 'staged photography'. Tableau vivant is a more precise term to use, if the staged picture obviously draws on the traditions and conventions of either the theatre or painting.

Andreas Gursky (photographer, Germany)

Andreas Gursky is a German photographer best known for his massive architectural and perspective photographs. He uses extremely wide, panoramic-like angles to create an overwhelming sense of presence and space. He generally shoots subjects that bear some sort of repetition ? people, windows, foodstuffs, you name it ? and exploits their undiscovered beauty.
Andreas Gursky also holds the record for the worlds most expensive photograph ever sold. His 99 Cent II Diptych ? sized at 207cm by 337cm ? sold three prints, each over $2,000,000. The highest one topping out at an astonishing and record breaking $3,340,456.


Visually, Gursky is drawn to large, anonymous, man-made spaces?high-rise facades at night, office lobbies, stock exchanges, the interiors of big box retailers (See his print 99 Cent II Diptychon). In a 2001 retrospective, New York's Museum of Modern Art called the artist's work, "a sophisticated art of unembellished observation. It is thanks to the artfulness of Gursky's fictions that we recognize his world as our own." Gursky?s style is enigmatic and deadpan. There is little to no explanation or manipulation on the works. His photography is straightforward.

Andreas Gursky and The Contemporary Sublime

In place of nature we find the invasive landmarks of a global economy Taken as a whole, Gursky's work constitutes a map of the postmodern civilized world.
The vision is not a comforting one. Many of Gursky's pictures, though beautiful, intensely colorful, and wonderfully composed, leave the viewer with an uneasy feeling. Whether because of the spread of architectures or the bustling crowds they show, or because of the equalizing aesthetic treatment given to all subjects, from the Dolomite Mountains to a car show in France, the pictures are both awe-inspiring and disturbing.

Size does matter!

Or how and why pictures from medium format and larger camera often look immersive

Answer: it's the lens spatial frequency advantage

It always struck me how medium and large format pictures looked more life-like to me. I've realized that it's not (just) a question of resolution and dynamic range nor shallow dof, as even "low" resolution jpeg pictures on the web could look vivid / "real".

Great 3D / life-like feel © Leszek Kowalski @

Forget Film vs digital, forget CCD vs CMOS, forget anti-aliasing filter or not, forget megapixel race: what matters most - for image quality - is the sensor size... not because of the sensor performance but because of the lens!


  • For an identical image, if the format is larger, the same captured detail will be larger = you are using lower spatial frequencies that are easier to resolve (higher transmitted contrast) by the lens = better micro-contrast (the image that will be "sampled" by the sensor is better to begin with!).
    It's a shift to lower spatial frequencies: The lens is used in a "better zone" of its MTF, meaning used in a better zone of its optical quality, giving a better micro contrast etc...

e.g. a 10um detail on a 24 x 36 mm sensor = a 18.3um detail on a 56 x 56 mm sensor. The lens will have to resolve a smaller detail on the 24 x 36 than on the 56 x 56 = the lense will have to be used at higher spatial frequencies - at lower contrast. 10um would correspond to 50 lp/mm versus 18.3um to 27 lp/mm. A lens transmitted contrast at 27lp/mm is better than at 50lp/mm (especially at wide apertures, see page 8 graph of Carl Zeiss' paper on reading MTFs

Summary: The larger the format, the lower the spatial frequencies beeing sampled, the better the micro transmitted contrast


An other simple way to look at it: A large format will "capture" more analogical optical details.

n.b. larger format "equivalent" lenses, as having to cover a larger image circle are more difficult to build and often have less good transmitted contrast at equal absolute spatial frequencies (that's why in my schema I shifted the blue - larger format lens MTF - to the left compared to the pink - smaller format), but as the used spatial frequencies are lower the end result is better overall transmission for the larger format (as long as the reduced transmission by absolute frequency performance is not bigger than the gain from using lower frequencies).
So maybe a 44x33 with a bad lens is not better than 24x36 with a good lens, but as long you're using good lenses and a larger enough format, the image being sampled is better to begin with, across all format relative spatial frequencies, not just at high resolution. Will this matter in the "final" image, that's another question (it depends on the image style... the amount of destruction by post-processing, print/screen quality & size, your taste)

Seeing (at Paris Photo 2011) a Richard Learoyd 8h exposure, giant direct-positive image, taken with his room sized camera obscura is an amazing experience c.f. Uncomfortably Close: Richard Learoyd's, Presences, that will not contradict this observation!

It's cost (and weight), not quality that keeps sensors small!

n.b. Obviously having a high number of megapixel is nice as lenses can produce (barely) visible/usable "details" up to MTF 5-2% transmission = at very high spatial frequencies. To sample those a high resolution is needed. High megapixel is good, but could not replace using the lens at its best ! As long as the sensor can sample at least the lens details at its MTF50 threshold, a 56x56 mm image will always be better than a 24x36 image, no matter the pixel count (as long as the lenses are good).

n.b. I'm wondering if semi / cropped - medium format digital camera with sensors as (too) small as 33 x 44 mm (Hasselblad H4D-40), 30 x 45 mm (Leica S2), up to (better) 49.1 x 36.8 mm (Hasselblad CFV-50), 56 x 36 mm (Leaf Aptus-II 10) 53.7 x 40.4 mm (Leaf Aptus-II 12) are worth the price! Compared to 24x36 they will, respectively, get a reduction - compared to 24x36 ff - in lens used spatial frequencies (= uncrop factor) of 1.27, 1.24, 1.42, 1.54, 1.55 (a detail corresponding to a spatial frequency of 50lp/mm would be reduced to, respectively 39.4, 40.3, 35.2, 32.47, 32.25 lp/mm)...

p.s. 'bought a Hasselblad CFV-50 digital back (with a KAF-50100 49.1 x 36.8mm - 2x FF surface! - 50Mpx CCD sensor from TrueSense=Kodak) Aug. 2012 ... (giving a 30% reduction in spatial frequencies for same view angle compared to 24x36 FF) to fit a 1980 used 500C/M, forming an acceptably cropped MF system. ;-)

Almost affordable Hasselblad


Seen on a endgadget post.


31 megapixel Medium Format (sensor likely only 48mm x 36mm like on H4D-40) + lens; under 10000 euros: 9995 euros ($13355) (13210 CHF) + taxes.

do I want a cropped medium format camera?

With such a "small" medium format 48mm x 36mm sensor (= 60mm diagonal versus 43.3mm for 35mm full frame [ff]) there is a 0.72 crop factor (or 1.39x uncrop factor) compared to ff. The corresponding lens for a ff 43.3mm would be a 60mm; the reduction in dof would be 1.39 x (~= the crop factor) for the same aperture on a subject at the same distance (with the increase in sensor size, there will be an increase in dof - as less magnification is required to produce a same sized image - of 1.39 over a concomitant decrease of 1.39 ^2 due to the lens focal increase (to preserve the angle view): 1.39 ^2 / 1.39 = 1.39). A depth of field reduced by ~1.4: nice - if you like pictures with "relief"/focus-contrast!

BUT medium format lenses don't have great maximum apertures! Here the 80mm "standard" lens opens only at 2.8: what you gain in loss of dof by having a longer focal lenght (for the same view angle and aperture) you lose it by not having the lens fast enough! from ff with a 50mm to cmf with a 70mm (does not exists, lets consider 80mm f/2.8) you have ~ 1.4 less dof, but from f1.4 to f2.8 you have ~ 2x more dof! So in fact you could have shallower depth of field with the 35mm ff!
c.f. normankoren dof tutorial, and Depth of field tutorial and Eliminate Depth of Field Confusion
n.b. going from 35mm ff to APS-C you get 1.6 x increased dof but here the APS-C or other smaller crop sensor lenses are not (>=1.35 f-stop) faster than 35mm ff to compensate!...

So 24x36mm "full frame" with fast lenses is equivalent or better than 48x36mm "medium" format with slow lenses for having a shallow dof! (when being 2 f-stops faster, for the same view angle on its system).
But the medium format "magic" is not just about shallow dof: it's the increased focus contrast out-of-focus regions (if any) and in-focus regions with higher micro contrast. As any lens is better at resolving larger details and as details to resolve are bigger on a larger sensor area: the whole image is better resolved = has a higher micro contrast = higher fidelity / life-likeness.

A Hasselblad CFV-50 digital back (with a KAF-50100 49.1x36.8mm 50Mpx CCD sensor from TrueSense[Kodak]) looks tempting

Megapixel Saneness

I don't understand all the fuzz about digital sensor size and resolution versus lens resolution. Higher resolution is NOT (completely) madness! To me the "megapixel madness" meme is "sampling misunderstanding"!
I don't understand this worry about sensors out resolving lenses wrongly calculated by considering that one (lens) cycle should not be covered by more than 2 sensor pixels...


For example if you have 6.4um pixel size sensor (like my Canon 5DII 21Mpx 24x36mm sensor) you have like (1000/6.4) 156 pixels / mm but this doesn't mean you need a lens that can resolve at least 156 lp / mm to make good use of the sensor! First lp means line pairs! (a black plus a white line! otherwise how can you see that there are lines!) so that would be ~ 68 lp/mm for the limit where the lens "could" be out-resolved by the sensor (n.b. >= 68lp/mm is ~ a common lens resolution). Moreover lp/mm: well, yes; but at what contrast? the world is not black or white! (Lp/mm is an old crude, non objective measure, now we use MTF measures). To represent a transition from black to white shouldn't we use more than 2 pixel?! The smallest "detail" a lens can resolve doesn't exists on its own but only in contrast with another detail (or background) + considering the phase/alignment (to the digital sensor) "it" should therefore be sampled with more than one pixels.
I know, when stopped down, lenses have their resolving power going down due to light diffraction: some think that they are then out-resolved by the sensor (see Why Moore?s Law Does Not Apply to Digital Photography) and anyway many lenses are not that good, but to me a "perfect" - or a good enough - high-end sensor must be able to sample - with more than 1 pixel! - the finest details from what the best lens could get at its best aperture under the best conditions! Not very important for vacation "souvenir" small prints, but for large ones yes!

To correctly record all lens analogical "points" - ~ corresponding to the smallest confusion circle the lens can produce - one must sample them at greater than their resolution (See Nyquist frequency "aliasing can be avoided if the Nyquist frequency is greater than the bandwidth, or maximum component frequency, of the signal being sampled").

How well a spatial frequency pattern is resolved by a pixel grid depends on the precise alignment (phase) of the pattern with their grid. On average, you can reliably resolve only about 70% of Nyquist; the reduction is known as the Kell factor. In other words, you need at least something like 2.8 pixels/cycle for reliable resolution and reconstruction of a spatial frequency. ... A small amount of oversampling is good, but more is overkill
Camera Lenses: From Box Camera to Digital (via google books)

Let's say we want 3 pixels to sample a cycle (line pair "section"), and we use a good 80 lp/mm (?at 50% contrast?) 35mm lens, so we need a 240 pixel/mm sensor; for 24mm = 5760 pixel vertically = 5760 x 8640 pixels = we need at least 50 megapixels before the (35mm full frame) sensor really out-resolves the lens (technicaly that sensor would be out resolving the lens, but this is required for a perfect sampling).
Moreover one must also remember that almost all sensors are bayer matrices (via a color filter array) where half of the pixels are sensitive to green and 25% to red, 25% to blue; their spatial resolution is higher than their color resolution could we say. The real colors are interpolated by demosaicing. I'm sure (high sensitivity, low noise) 50 megapixels for a 35mm full frame sensors wouldn't be a crazy thing!
To summary: (35mm) sensors are not yet lens limited.

And if we go to medium or large format: this is interesting. Due to the requirement of a larger image circle, and therefore construction difficulties (design compromises) medium format lenses have less resolving power per mm ... so considering a (>=) 60 lp/mm lens = (still with 3px for one lp) 180 pixel/mm x 56mm = 10080 pixels horizontally = 10080 x 7560 pixels for a ~ 56 x 42mm "645" sensor (e.g. the Phase One P 65+) = (>=) 76 megapixels (pixel size: 5.6um)...
With the "small" Hasselblad 40x54mm (e.g. H4D-60) sensor you'll need (>=) 70 megapixels. In short 100Mpx would be nice for small digital MF sensors.

I think the mega-pixels race (and also the higher sensitivity / lower noise + wide dynamic range + high color depth race) is not over! There will be a limit where additional sensor resolution won't be useful, but we're not that quite there yet! (but not far) ... For 35mm (full frame) sensor format: 1 more additional (pixel number) doubling would be nice, then halving of the cost, increasing quality/sensitivity would represent a more interesting Moore?s Law.

n.b. for the nostalgics: I've heard that film is not as crisp as digital, in part due to scattering of light in the emulsion, inter-reflections (= less resolving power, less micro contrast) and higher noise (~ grain)! The resolving power of Fuji Reala (100iso) - my favorite film with fuji nps 160 - is rated 63 "lines" (yes, line widths; black and white, not cycles/pairs or it's a typo?) per millimeter at a 1.6 to 1 target (weak) contrast ratio = 32 lp/mm, and 125 l/mm at 1000:1 (not a current micro-contrast, more for astronomic photography!?) = 62 lp/mm representing, for 35mm, (125x24 x 125x36) 13Mpx (at 1.6:1 of subject contrast would be 63x24x63x36 = 3.5Mpx). (n.b. those "old" resolution numbers/units look strange ... on the fuji provided MTF graph MTF 50% looks like 60 lp/mm : 13Mpx)
To correctly sample that film one would need 1.11^2 times more pixels, but in itself the film represents 4 to 13 millions of analogic "points" and should be for sure spatially maxed out by a ~ 13Mpx digital sensor (nevertheless as color film "dots" can capture any color - no bayer matrix!- film is probably not so bad in "chrominance" resolution, although with its complex layer system, reflexion etc I'm not so sure). I would say that it looks like actual 35mm full frame sensor (e.g. Canon 5DII 21 megapixels) are better than film but not uselessly out-resolving a 80 lp/mm lens ...

Cool site:

Today, the pyramids of the industrial revolution just uselessly stand in the way, they're a scar in the landscape.
The deafening noises have been replaced by silence, but if you listen carefully they will tell you their story.

Seitz 160Mpx digital camera

High end Swiss 6x17 panoramic camera with a special 160Mpx! sensor [21'250 x 7'500px, ISO 500-10'000!, 48-bit depth, high dynamic range] developed by DALSA Corporation.
OK, it's not a normal (area-array) sensor, but a linear/scan sensor; it doesn't cover the entire image area, the image must be scanned across the sensor as it builds up the image from the captured rows of pixels (not great for action photography)! A 160 million pixel 6x17 panorama takes one second.

45'500 CHF (28'900 Euro) [Mobile version]
Too expensive for a non professional! ...

A 6x17 digital panorama (uncompressed) has about 950 MB! Data is transferred by gigabit ethernet from the sensor to a storage device or computer.

For those who might think - do we need such high resolution: I'll just say 2 words: "giant prints!"... (obviously it's not meant for vacation pictures that you watch on a computer screen!)

It's a small world after all that frame tilting

How To Make Anything Look Like a Toy

In artist Olivo Barbieri 's photographs, the six-acre Roman Colosseum resembles an upside-down soda cap, Las Vegas and Rome look like model-train landscapes, and an 80,000-ton boat seems as if a child could pluck it from the water.

It's often hard to convince people that Olivo Barbieri's aerial photographs are real!

To create this effect, Barbieri uses a tilt-frame camera to shift the plane of focus so that it is out of alignment with the film. Normally, this allows wide-angle aerial views to be captured in proper perspective. But used incorrectly, an optical illusion occurs.

Japanese photographer Naoki Honjo (and now many others) uses the same technique

Gimmicky? but really cool! Likely a trend that's gonna be over used!

Could we do the same with a simple shift/tilt lense ?

Canon EOS 5Dii

First affordable full-frame (35 mm) sensor digital camera (5D [12.8Mpix] released October 2005, 5D mark II [21Mpix] Sept 2008).

Canon 5D mark II review

  • 21 megapixel full frame (35mm) CMOS sensor (identical to the sensor in the EOS-1Ds Mark III). Excellent resolution, very good high ISO performance!
  • 1080 24p video usable in low light conditions with very good quality!


We have always placed a heavy emphasis on image quality, and all other things aside this means the 5D Mark II has to receive our highest rating. When you consider the price of the EOS-1Ds Mark III, the 5D Mark II seems like quite a bargain.

via body now (April 2011) at ~2200 CHF (2700$, 1900euro)

(p.s. 'bought one - with 50mm/f1.4 - June 17 2009 ... stolen Nov 2009, again! Nov. 2012 .. replaced by 6D)

First 100+ Million Pixel CCD Image Sensor

First 4x4 inch captor! 10,560 x 10,560 pixels (111 million pixels), developed by DALSA Semiconductor (to aid the U.S. Naval Observatory's Astrometry Department in precisely determining the position and motion of celestial objects).
I hope this kind of sensor will be used for future large format digital camera! + it's a sign that sensors CAN be bigger and have very high resolution!
It looks it was custom made, probably cost 'quite a lot'!...

Understanding Digital Blending

High Dynamic Range imaging (tiring, often kitch and dramatic) is all the rage these days and it can be done easily with images from even low end digital cameras and without an expensive Photoshop plugin.

This is funny: in fact it's the opposite of High Dynamic Range imaging! It's representing a high dynamic range into the limited dynamic range of your jpeg & display (8bits/channel) = technically it's "dynamic range reduction", generally using badly applied "Local Adaptation" method via photoshop!...

Is there something uglier than those HDR images!? yes: light-painting-photography ;-)

Digital details

Film vs. Digital Cameras


How much detail can you capture and scan?

Digital cameras will match Fujichrome Velvi 35mm film when they reach more than about 10 megapixels. Somewhere in the 12-16 megapixels will produce color image quality comparable to 35 mm film (this is a compromise of more intensity detail and less color detail than film). Somewhat fewer megapixels, approximately 8-10 Mpixels will match 35mm film intensity detail but at below 35mm film color detail.

Medium format film: about 50 megapixels are needed to match Fujichrome Velvia in 6 x 4.5 cm.

Large format: more than 200 megapixels are needed to match 4x5 Fujichrome Velvia film. How much more needs further testing.

n.b. (aug 2009): see my 1st n.b. in my Megapixel Saneness article
My (~theoretical) calculation, based on declared Fuji Reala film resolution indicates that 13Mpix (for 35mm format) will be required to reach film maximum resolution. Note: but when you scan a film it's better to do it at 1.11 - 1.4x it's resolution (in one dimension) (at a resolution high enough to resolve all the details without aliasing/phase problems) = 24Mpix for (35mm) reala = ~4200dpi!

(Very!) Old color photos

Monastery from the Solarium (Russia, ~1909)

seen Sept 2010:

Studies on Lindozero (laika [dog]) 1915

Using Harris Shutter Effect (combination of individual monochrome photos taken and reproduced with color filters)

IMO photography is the greatest , although not most advanced, invention of humanity. The fact that something so simple can not only transport you to another place and time, but that it can also stir emotions without a word. Always amazing.

America in color, 1939-1943

Exhibition at the Library of Congress
Bound for glory; America in color, 1939-1943.

America in Color is the first major exhibition of the little known color images taken by photographers of the Farm Security Administration/Office of War Information (FSA/OWI). Comprised of seventy digital prints made from color transparencies taken between 1939 and 1943, this exhibition reveals a surprisingly vibrant world that has typically been viewed only through black-and-white images. These vivid scenes and portraits capture the effects of the Depression on America's rural and small town populations, the nation's subsequent economic recovery and industrial growth, and the country's great mobilization for World War II.
