>61MP image files for peepers
« on: October 01, 2010, 06:41:21 AM »

I thought this is worth a separate thread which may last a while.
Over the next weeks/ months we'll have more and more photographers/ reps/ reviewers buying and using the new Aptus-II 12 and Aptus-II 12R backs.
I know there are many people here who are interested in seeing what this new product is capable of and do not have an easy or immediate access to it. Some simply like or need to see what the current top-end sensor/ back/ lens technology can deliver as they consider it over a competitive product (for example a multi-shot camera)

The idea is to provide raw files, however at this point in time the software required for opening them is not published yet, so initially we will have to do with full size processed images

Here's a couple available for download:

Enjoy, yair

Hi Yair,

thanks for providing the file!

2 questions:
- is it a hand held or tripod shot?
- is it the 80D, or the 80LS lens?

BTW: apparently it's a 61MB file...

Unfortunately, the link is not valid any more. Could you upload it somewhere else?

Hi, Yair...

Was this post processed, or just default sharpening?

I notice that there are black pixels adjacent to the white pixels, left end of hand rail, center of picture.

It seems that the back does not out-resolve the lens.

Hi Dick, it was processed using Product presets in Leaf Capture, no post processing done to it

Modified the link above and added another file there

Thanks for posting, Yair.

All, I purchased a 5GB/48hr download rights to the site where the files are hosted, but obviously won't be able to use all the capacity in that time.  You are welcome to use my code to access these files for as long as it remains valid.

stunning.

Sorry. I have to post this...

For A12__000041, 100% 1/3 from the bottom where the people are on the green. The sensor seems to have an issue resolving the people and the grass separately. There is a person kicking a ball around who's face looks like the Hulk. Also the large woman in the foreground facing the camera has black spots all over her. Maybe this is normal, but I haven't seen this anywhere before. However, the image of the fabrics looks really great.

I might be too critical. "Stunning" would be the last thing I think of. 80 iso should be better.

aren't these typical things that get sorted out in a final release? I guess it's firmware version 0.9 and just a beta of the raw software. All the images also show a line on the top image border... so I'm sure this is not the final version.

Jonathan, she's also out-of-focus and her "face" is at about -2.5 EV from midtones so yes I think you're being too critical:-)

I guess you have not seen this before 'cause you have not seen so much detail before at this size...I think I can see a bold eagle inside the net cage at the Zoo on the Right

Focus is on the people+trees (not on infinity) at the centre of the frame and at f10 with a standard lens I think the broad DOF is also quite good.

Yair,
The relationship of the sensor size to it's resolution is too far apart. I don't know where the limit was for this sensor's dimensions, but it seems like it was around 60mp. Maybe if there was a more accurate algorithm for interpolating the pixels it would be a different story.

I have no data to support what I am saying. It's just what my eye is telling me. Grass shouldn't be on someones face unless its really on their face.

The fabrics shot looks great. I find it hard to describe the rest.. to be honest, 100% crop from P45+ looks in my opinion better. Better is of course a highly subjective term and I'm using it on purpose- maybe there is some extra pixel count, maybe there are some details which you wouldn't normally see, but come on, in general the whole image is rippled/smudged! It gives me a terrible, plastic feeling about the whole image and I'd rather scan transparents than have a digital back producing something like that. Maybe it's the defaults with which the image was processed.. I know that I like a file from P45+ with defaults than this. Maybe studio / artificial light will do this sensor justice, maybe its the lenses (I don't have experience with DF and new lenses lineup).. something is definitely wrong in my opinion. Again- subjective opinion.

Actually there are black spots everywhere not just on the big ladies face, but it didn't concern me as I expect they'll get that sorted out with final versions of firmware and software. Overall these look very promising to me.  Probably the reason why the fabric image looked great comparatively was that it was shot with the Rodenstock 90mm APO which is a stunning lens and in studio with controlled light etc.

Thanks for sharing these images.

i think the files look very very impressive, apart from some conversion errors as these dots which i cant imagine to be  a problem
to be fixed in later sw versions.  resolution, color definition, sharpness and SIZE are really impressive i.m.o.

I think before anyone can judge those files, they need more refinement either in processing or software.

Looks like pretty heavy sharpening to me.

obviously there will be some refinement but at least they already show that a decent standard lens won't have problems to resolve high enough edge to edge...
The city park scene is a handheld shot (I've seen it already at Photokina and Yair told me so) ... which I am finding quite impressive therefore.
Whether the river scene is a handheld or tripod shot, I don't know... I guess it is handheld, too.
So for someone looking for a high rez capture device the samples are very, very promising, IMO, ... in particular the fabrics shot, naturally.

Seeing as you are pixel peeping the guy kicking the football has his face made up of 1.5 mm or less from the total width of the image which is 870 mm...
I can't see a trannie or neg then being scanned etc giving anything better.
The big woman in the foreground occupies 21 mm of the 870 and is out of focus and is somewhere in the 3/4 tone area of the image and it has been slightly over sharpened.
I think in the greater scheme of things, I guess hand held, 80mm lens maybe not the best lens out there and the 2 elements you referred to Jonathan the result is quite impressive just the same. :-*

...image and it has been slightly over sharpened.
I think Yair said the the images were un-sharpened, or "default".

I would hope that there are options to sharpen less, for example for portraiture... perhaps there is a default  (but customizable) level of sharpening for portraiture and another for landscape... but pros and advanced amateurs like to have options,,, and be in control.
