Do all your tests on the Aptus II 12 as well and see how they compare.

1) Performance when shooting tethered to:
a) Macbook Pro i7 with 8GB RAM
b) Mac Pro 12 core with 8GB RAM
(30 images in continuous mode)
and direct to CF card
2) ISO 35 - 2 minutes exposure - noise in dark area
3) ISO 35 - how long we can expose in about 32 degrees F
4) Performance - battery in about 32 degrees F
5) Shooting with Alpa or Arca RMD3Di with wide lens :Schneider Apo-Digitar 5.6/24 mm XL ( with tilt)




#5 was easy - the 24mm will not cover on either the IQ160 or IQ180 (nor on the P65+, Aptus-II 12, etc).

I agree!
That is really interesting to see.

So - since this is cross posting to GetDPI, the combined tests from both forums that have been suggested are:


*Large movements with wide lenses on tech camera

*C1 handling of casts and falloff

*Dynamic range in practice

*New screen in use with tech camera

*Perceived image quality compared to P65+ (other than MP)

*Video screen capture of the live view

*Blooming control - shoot through tree tops with sun, etc, car bumpers in sun

*Freezing, elephants, car driving over, molten lava

*Powered off to shooting time

*Real world long exposure limits

*Focus mask evaluation

*Tethered performance 30 consecutive captures when tethered to: macbook pro i7/8GB, 12 core tower/8GB, and also to cf card

*Iso 35 2 minute exposure

*Iso 35 how long can one expose in 32 degrees

*Battery performance at 32 degrees

*Compared to Aptus II 12

*General video tutorial

*Iso performance

*P1 lenses, 28mm, 45mm, 75-150, with and without lcc to check shadow color cast

*Frame count for first battery charge, including messing around with menus, etc, reviewing images, etc.

*Composition mode - how long to 100% zoom

*Color anomalies

*P+ > IQ menu differences

*Features that work (or don't) with Contax


We'll have all these finished by the end of the day. Complete results tomorrow. May be a delay in the elephant testing and the molten lava (wickedly suggested by Nick T).

In all seriousness, we'll begin these right away and post results as we confirm them.

Thanks everyone for the input - and always open to more.

Hi Steve,

If there is still time to add to the list I would like to see
how the back performs in a landscape-type application with lenses
such as the 28 and 45 mm with apertures moving from f11 through to f22 to
see how serious the image degrades relative to aperture

Color Rendition of the IQ against Drum scanned Kodak Ektar 100 4x5 inch film.

Steve, just to clarify:  With my #4, I am more interested in the process of focusing using a tech camera and the IQ180.  i.e. how the combination of the high-res screen, zoom and any other enabled firmware work together.  Maybe also a comment on how the new IQ workflow compares to other DB's.

I suspect this will all come out in the wash anyway as you do your testing.  Thanks again for doing these tests.

Sorry bud, that ship sailed years ago...seriously, it's not in the bit useful to compare MF digital capture to film. Film sucks...move on.

Hi,

With both Ektar (or any negative film) "correct" color essentially arises in post. It is simply not meaningful of discussion color rendition of scanned film or a digital sensor. A digital sensor is essentially a black and white device with color information. The color information is applied in raw conversion.

That said, the CGA (Color Grid Array) can have different properties (transmission characteristics), so different sensors can have different potential of capturing color. But, most of the color is actually created in postprocessing and that is highly variable.

Best regards
Erik

I think Jeff is okay - I just remember his sentence (from a video):
"Why be subtle, when you can be ...unsubtle ?"

The confrontation was a little bit painful, but helpful as well,
because it forced me to overthink some questions.
I'm not made of sugar.
And I'll still not give up film.
Peace.

Maybe color film anyway. There's something about B&W that still appeals to me especially for art work, and actually instant film too.  I know people will write how you can recreate these looks in post, but overall I don't see it as the same.  The market still rewards real film with higher selling prices too.  That said I don't shoot that much film, and what's all this got to do with the IQ 180 anyhow?

Hi Guys,

Do you have any results which you could share?

With all due respect I don't agree with you. There are many photogs all around the turf that still find film more beautiful or love the difference. The 39mp 48X36 sensor was comparable to 4X5. MR kinda say that the newer backs may aproach 8X10. Maybe  that's the comparison that many want to see now at Lula.
Jesus, I can't believe I'm addressing this to someone with your credentials!  ;)

If film was twice as beautiful as digital capture, which I think in some instances it may be, in the world of advertising and commerce it's just not viable.  At least for large projects.

We just finished two projects and both times, three days  later. . . max., the clients have galleries of 6,000 images and web play video from the RED.

Three days after that the AD's have inserted images for POS and our studios has cut and delivered 3 minute intro video of the campaign.

In the world of instant commerce film doesn't register.

Now with that being said I've seen more than a few people go back to film for their personal work and smaller production commerce. 

It's pretty, still requires some kind of post work, but with the older large legacy cameras it makes kind of a retro statement that not only gives a little different look, but is a nice marketing slant for the artist.

Then of course there's the widelux, which nobody has done with digital in a camera that is smaller than a toyota.

Hi,

There is one area where I actually would suggest film is superior digital and that is the reproduction of specular highlights. Film saturates and digital clips. It may be that film would saturate before digital clips, but there is still a difference.

For the rest of it I don't think there are magical properties of film. I'd suggest that film like effects can be achieved using curves and controls in raw development. On the other hand there has been a lot of research going on in developing the characteristics of film.

Once I tested settings in "Alien Skin" emulating Velvia, the colors got much more snap! That is until I found out what was happening, saturation was increased and shadow detail clipped. So the shadows I spent a long time on so they would show decent detail just went black!

Best regards
Erik

Christoph asked for color rendition in scene with fog and water reflections.
Water reflections contain specular highlights and good fog rendition was easy to record due to the random position of the silver halides. I can assume that Christoph may find these 2 questionable. At least every now and then.
