First CX1 samples (now also full resolution files)!

I just found this Chinese page with some CX1 samples. Unfortunately, all of them are very small and taken only at ISO80-100. So it's impossible to say anything about CX1 image quality...

Here is another Chinese page. First seven shots are an example of new multi AF feature. However, much more interesting are the bottom two photos, displaying the difference between the non-DR and DR mode! These two indoor shots were taken at ISO200. Unfortunately, still too small. But the DR one looks very promising!

And one more, this time Japanese, which, as I believe, displays DR mode in action...

Re: First (small) CX1 samples!

Tim, I wouldn't say it's underexposed. It's just the first image that seems to be overexposed ;) And it's hard to say what level of DR has been used in the second shot? I think we will have to wait for some real and higher res. samples.
 
Ricoh Japan just updated their CX1 specification page with full resolution samples, including the "interior with china" photo.

Although all published shots were taken at low ISO, I really think they look much better than files form R8/R10. grainy in shadows and foliage, but that's good news! At least they do not seem to be smeared and oversharpened to death like photos from its predecessors. I hope to see some real and high ISO samples soon.

Hello,

Note: I was somewhat confused and posted this in another thread first...

thelps wrote that the china (porcellain) sample image (sample_06) with NR looks underexposed. I compared both versions and to my taste, the china looks much nicer in the original image without NR. So, I used Photoshop Elements 6* to push the NR version in the direction of the original version. Here is my result (small version):
sample_06_gw_sm.jpg

Large version: http://www.waloszek.de/sample_06_gw.jpg
My wife, who might be a CX1 candidate, liked the result!

Best regards, Gerd

*) Überarbeiten -> Beleuchtung anpassen -> Tiefen/Lichter: Tiefen aufhellen (40%), Mittelton-Kontrast (50%) <- regrettably only in German
 
Yes Gerd, your edited china shot looks much warmer and brighter. I think there will be enough options directly in CX1 menu to make the DR result brighter or darker. There are 4 levels of DR strength and one should also be able to use exposure compensation.
 
Gerd, your version certainly shows a lot of detail in the curtains - very well done. :) Goes to show what can be done with a jpg. I suppose it is a bit unfair of me to say the example was underexposed as my monitor is not calibrated. :eek:

Ahh, I was not aware of the 4 levels. :shock: It would be interesting to see an image with all 4 applied and one normal (no DR) side by side to see the effects. :?:

I will surely do such test Tim ;) I'm also planing to do a comparison of R7, R8, R10 and CX1 in terms of high ISO noise, sharpening and image processing in general.
 
Tim and Pavel,

Just wrote a post in reply to you, thought I save it and off it was gone (it must be somewhere)... So, here is my second try...

I found the porcellain image on the Chinese/Japane site and thought, I process it in response to Tim's post. However, soon after, I found the same photo on the Ricoh site in larger size and decided to use that photo for processing. Only later, I found out that the Ricoh version shows much more details than the darker C/J version. Thus, my processing attempt started from an already better version.

Best regards and sorry for the confusion, Gerd

For comparison, all samples in 500*375 (as on the C/J site):

114988433.jpg
(light C/J version)

114988434.jpg
(dark C/J version)

sample_06_sm.jpg
(Ricoh version)

sample_06_gw_sm.jpg
(my processed version of Ricoh version)
 
Thanks for this comparison Gerd! The last two photos look best with slight edge for your edited photo. I prefer warm colors in photos and your processing shows warm tones and details in shadows. Well done!

As for saved posts (drafts), you can find them in User Control Panel...

Thank you for the hint, Pavel! I don't know why I overlooked the user control panel -- I never took notice of it (up to now)...

Some new full size shots...

adapterik, you are right. This shot is most probably taken in DR mode. But I think this set shows much better what the CX1 DR mode can do...

Yes, I think the building show shows the double-shot DR enhancement very well -- should be something that impressive on the Ricoh site!

However, for me this example of the "double exposure" double shot pretty much shoots down the magic of this feature. Is it useful only on a tripod?

The software to handle the matching of the two shots should be much better than that at matching the images. When you think about it, there would need to be some pretty neat tricks to do this in-camera process well. There really should be really good effort to reduce any possible double-exposure effects. Camera movement needs to be compensated for as precisely as possible. Subjects in motion should not be "double shot" at all. And perhaps some areas of the photo don't need any DR adjustment -- the exposure should be fine for the primary subject, and just one extreme or the other (e.g. highlights) be compensated for in the second exposure (maybe a setting to go for more shadow or more highlight.). Better yet, keep both images, and allow the combining of the images to be tweaked later.

Then again, maybe I'm just a grumpy guy whose been looking for something mind-blowing from Ricoh :)

Erik.
 
From my experience with HDR software, the perfect alignment is the most critical part of HDR photography. In the Sony article about CMOS sensor used in CX1 is described how the sensor compensates the camera movements. The question is, if this "motion vector" feature is implemented in CX1?
http://www.sony.net/Products/SC-HP/cx_n ... ring3.html

In any case, in the flickr picture you pointed at, there is clearly visible that slow shutter speeds and moving subjects in general are not very DR mode friendly. I think that tripod is a must for slow shutters and if there are people or other moving subjects, you can expect motion artifacts to be seen in result photo even with fast shutter speeds.
