    I am using Mac OS 10.10.3.
    Thanks K-H. I have the plugin installed and use it with CS6. I thought you were trying to use ACR to open the files. Is 10.10.3 still in beta?

    Yup, still in beta. I signed up for it.

    The plugin seems to only open the high res files but not the regular ones of the E-M5 II.
    ACR doesn't open any of the E-M5 II files. CS6 just opens the .JPG files.
    That's my experience.

    You're describing the bag I'm planning to take on a trip to China later this year (with the 40-150 + TC that just arrived). Two bodies: EM1 and EM5. I have two of the latter, but might replace those (and the 12-50 and 75-300 II which won't get much use with the 12-40 and 40-150 here) for one Mark II. Like you, I mostly prefer the body size of the EM5 over the EM1. The latter is a natural fit for the 40-150 though. I use it without the grip, which I did receive for free due to a promotion here. As with the EM5, I think these grips make these cameras oversized.

Olympus seems to have put in a little sharpening, appropriate for web viewing or prints of a moderate size, in their OOC jpeg recipe. It gives rise to a halo extending about 2-3 pixels around each vertical or horizontal straight wire in your snowy porch picture. It is also visible at edges between regions of solid differing colors in Robin's pictures, such the hamburger buns, and lettuce leaves. Once we get some experience with the humongous .ORF raw files, it should be possible to sharpen only as is required.

    So who has seen shareable example of full RAW .ORF high resolution files from the M5 II?

    Re: OM-D E-M5 Mark II Pre-Order

    We Went to Crufts
    These are all with the 40-150 (I think)

    Jenni and Sooty (best young dog)


    Radka and Suzie (3rd best bitch)


    Blue


    Gasti - best dog - runner up best of breed


    Blue - runner up best bitch



    I shot ORF+jpg - but these were all processed from jpg (easier right now)

    The camera did really well in disgusting lighting and very fast moving action (these dogs are FAAAAAST!)

    Thanks Scott. Could you please post a 100% crop of my OOC JPG image demonstrating the effect? Also, I made available the .ORF file. When/if you develop your own JPG from it what do you get? TIA.

    I would like to clearly see and understand your observations. Thanks.

    Dog show @Jono -- How can the best dog only be the runner-up for Best of Breed? Incidentally, did you add flash or maneuver some lights into place to get the nice headshots on the dogs in what looks like a pretty dark setting?

    Here's what I hope will be a 100% crop from the fence wire shot, Which I understand was rendered in camera as a super fine resolution jpeg after taking one of the magic 40 MPx shots with the E-M5 II:



    What I see on my editing display is a white area surrounding each of the wires, horizontal, vertical or hexagonal. Let's see if works in web display.

    Mostly S-AF - you should have thought harder Scott (I'd have bet on you) - because the best bitch won best of breed

    No light manouvering, no flash, disgusting light

    Hi Scott, many thanks indeed. I am marveling at your excellent eye sight and skillful observations.
    Of course, you have correctly identified the white areas surrounding each of the wires, horizontal, vertical or hexagonal.
    I can see them now as well.
    Before I got fooled by some transient display feature of smugmug that has nothing to do with the phenomena you have described.
    Enough of that though.

    What I have done is look in detail at the following 4 images and extract 200% 1024x1024 crops.
    Here they are:

    • OOC JPG


    • This image is derived from the high res .ORF file with CS6 and the Olympus plugin.
    • Apparently some sharpening is baked into the plugin.
    • No further processing


    • This image is derived from the high res .ORF file with Iridient and sharpening applied by Iridient


    • This image is derived from the high res .ORF file with Iridient and no sharpening applied.


    - I have also tried the Olympus Viewer 3. But it cannot display correctly yet a hi res image with full resolution.

    So it appears sharpening has something to do with the white features you have pointed to.
    Thanks again for being so accurately observant and pointing it out. Thank you.

    PS: I took then the last unsharpened image and sharpened it with Nik. Also enhanced contrast a bit.


    The full resolution image is here: http://winklers.smugmug.com/2015-02-..._sharpened.jpg


    Scott, please let me know if you can see any of the white stripes. TIA.

    That last version is pretty nice. Haloes are gone. You hit the right sharpening approach with your Nik setting (in photoshop terms there are two parameters to play with, size and strength, and both matter).

    But I suspect that the best approach with these 40 MPx or 64 MPx images will depend on the image itself. Your dark grey wires against a snowy background are an invitation to form haloes (just as they naturally give rise to double line bokeh). Olympus probably cooked what they felt was a good typical setting into their OOC jpeg formula, and then cranked it up a bit to be on the safe side for early web reviews. I hope they dial it back a bit once we all trust them and they can trust us to only sharpen when it is needed.

    Note that the oversampled images will need some sharpening. Each pixel that has sampled all four Bayer filter values (sometimes the two greens differ) gets true color information but draws it from twice the original pixel spacing. Signal processing algorithms ("deconvolution") can correctly move image information below the Nyquist spatial frequency (that means stuff that varies smoothly over at least two pixel spacings) back to where it belonged. But high frequency information, which would be aliased anyway, and noise end up contributing to blur.

    Look at the experiments with the 100 MB RAW files that Dave Etchells (who knows about this stuff) did at Imaging Resource. He used a beta ACR and found things were a little soft. Then he added some sharpening that seemed just right for his fabric and typeface test image. The results beat a Nikon 810 and held up OK against a Pentax 645.

    I'll play with trial Iridient and whatever files I can find and hope that Capture One comes through soon in 8.2 or 8.3. That's my preferred tool, and they are the ones who have handled Fuji's funky files best.

    Re: OM-D E-M5 Mark II Pre-Order

    A HR shot of my silver maple tree using the 12-40 on the E-M5 II. This image has a lot of fine textural detail. Processed in Olympus HR plugin for Photoshop with default settings and then exported 64 MP tif file to LR. I only added light adaptive pre-sharpening in the NIK plugin and then exported a slightly cropped jpg to Flickr. If anyone would like to try alternative processing the original HR ORF file is available for download from my dropbox. I'm also interested in suggestions for alternative processing/sharpening workflows for these HR image files.

    Very nice K-H. What are your sharpening settings in NIK? I've been using about 50-70 % adaptive raw pre-sharpening in the LR plugin which works well for most of my HR images.

    Many thanks Carl.
    I typically use the default value (50%, never more than that though) of the Nik adaptive raw pre-sharpening, but exclude the sky from sharpening. If I use output sharpening at all, it would be typically at 25% or at most 30%. Higher can very easily produce jaggies. Also before any sharpening I use Define to rid the image of noise caused by high ISO or by increased clarity.

    A quick note. If one carefully looks at this hi res image then one can detect artifacts/jaggies around sharp edges. I also compared the images derived from the hi res ORF file with either CS6 or Iridient and found that CS6 seems to generate significantly stronger artifacts than Iridient. In order to avoid these kinds of issues it's probably best to display or print these hi res images at 50% resolution.

    K-H,

    many thanks for posting these and taking the effort!

    Having said that, one can see significant artifacts in the high res images , so I hope this will improve with further development of conversion SW.

    K-H, I have the same reaction to the 64MPx images that you are getting. They seem to have been taken a bit too far, perhaps losing something. Olympus seems to think that the real power of their multishot HR is 40 MPx, and they have designed an in-camera transform to jpg to achieve that. Maybe if you output 48 MPx jpeg files from Iridient's processing rather than 64 MPx, you would also catch that sweet spot.

    I see some cross hatching artifacts in a few areas of the rocks that are indicative of movement. I assume you were not experiencing an earthquake so could it also be some camera movement?

    Artifacts in these HR files tend to be subject (contrast, edge types), environmental (light, wind etc.), and post processing affected and I wouldn't generalize based on a few samples. I've made several excellent images and large prints using the 64 MP tif output from the plugin as well as Irident 40 MP output. It takes awhile to learn what will and will not work, but for me I like what is possible now and this little camera is giving my Sony A7r a run for the money.

    Thanks John. That's good to know.
    Are there different L-plate/grip for E-M1, EM5, or E-M5 Mark II?
    Or are they all the same?
    TIA.

    Re: OM-D E-M5 Mark II Pre-Order

    they are all different due to changes in the base shape and hole locations, etc... the Em1 does not need the grip portion but both the EM-5 versions can use one.

    the rotating LCD on the Mark II makes that end not so useable for the L-plate, so for that model, i am putting it on the other end (with card access, of course)

    Scott and Carl, Many thanks for your feedback. Much appreciated.

    After checking into this image a bit more I would like to come back to the apparent issue in a bit more detail. As my snow image above has demonstrated at least to me, the E-M5 II is capable of high resolution, pretty much artifact free quality images, provided one uses sufficient care in shooting and post-processing an image. So if something doesn't look quite right, the question arises: WHY?

    The snow scene I shot from within my house, wind not causing camera motion. The tree branches may have been minimally affected by wind, but certainly not the fence wires. Also the grey stripes, in the first version of the image derived from the raw file, could be traced back to post-processing inadequacies and eventually avoided.

    The current image



    was shot about 15 yards away from a road with heavy car traffic. There might also have been an occasional minimal puff of wind. This could have possibly had a slight impact on camera motion with negative consequences. So I would like to examine the central part of the image a little closer.

    When shooting in high res mode the E-M5 Mark II, one has to use a tripod and one gets three files per shot if the camera settings are set to SL F + RAW and High Res Shot, namely an .ORF, .ORI, and a 7296x5472 .JPG image. Of course, PS CS6 can read the .JPG image. With the help of the Olympus High Res Shot Raw File Photoshop Plug-in Software Software Download | Olympus High Res Shot Raw File Photoshop Plug-in | OLYMPUS IMAGING CS6 can also read in the .ORF file, resulting in a 9216x6912 image. However, so far I am not aware how to directly read in a .ORI file with CS6.

    In contrast Iridient can read in all 3 files, the .ORF, .ORI, and the 7296x5472 .JPG image.

    Iridient can also save the .ORF file as a 16 bit .tif image in these pixel sizes 4608x3456, 7296x5472, 9216x6912, and 12288x9216. Other pixel sizes seem possible, but I have not tried them.

    Likewise Iridient handles .ORI files.

    Whereas for the .ORF file the E-M5 Mark II has combined several shots into a single file, with advantages and apparent disadvantages, the .ORI file contains the data just from a single shot. So it's very convenient to retreat to a single shot image if the multiple shot composite doesn't give the desired outcome, for whatever reason.

    In the following I have used CS6 (with Olympus Plugin) and Iridient to generate images and crop out the central part.

    Processed with CS6 (with Olympus Plugin), default settings. Image shot at Date Time: Mar 11, 2015, 6:21:19 PM.

    I clearly can see the diagonal stripes in many parts of this crop, going from the upper left to the lower right.

    Iridient has the following panels: Expo Color Mono Curves Detail Lens.
    Processed with Iridient, default settings except all boxes checked in the Lens panel. Image shot at Date Time: Mar 11, 2015, 6:21:19 PM.

    Here the diagonal stripes seem less pronounced and are barely visible to my eyes.
    Clearly some sort of pattern is visible as an artifact in the image.
    Can one make that pattern more visible or preferentially make it disappear?

    Processed with Iridient, default settings except all boxes checked in the Lens panel. Image shot at Date Time: Mar 11, 2015, 6:21:19 PM.
    Here I also set in the Detail panel, Edge Detail from 100 to 500 = max, Texture/Micro Detail from 5 to 25 = max.

    Now the stripes have become more visible to me eyes.

    So in conclusion I agree with Carl that some unintended camera motion must have affected this composite image.


    The next question on mind is what does the image look like that can be derived from the one shot .ORI file?
    Here is the crop from it, processed the same way as the last image and mapped to the same size.
    Image shot at Date Time: Mar 11, 2015, 6:21:19 PM.

    Of course no sign of camera motion. To my eyes this image also has coarser features.

    K-H, Thanks for your tests and comparisons. Have you tried using the ORI file as temporary background layer and then brushing out the diagonal line artifacts? Also, I find that simply downsizing will remove most of these motion induced diagonal line artifacts you are being in 64 MP files at 100%.

    Thanks Carl. No, I won't do that as I have a better shot.
    But first let me finish my train of thought.

    So next I take the multiple shot images and compare them to the single shot image but at 4608x3456, so at 50% size for the larger images.

    .ORF processed with CS6 (with Olympus Plugin), default settings. Image shot at Date Time: Mar 11, 2015, 6:21:19 PM.


    .ORF processed with Iridient and in the Detail panel, Edge Detail = 500 = max, Texture/Micro Detail = 25 = max. Image shot at Date Time: Mar 11, 2015, 6:21:19 PM.


    .ORI processed with Iridient and in the Detail panel, Edge Detail = 500 = max, Texture/Micro Detail = 25 = max. Image shot at Date Time: Mar 11, 2015, 6:21:19 PM.

    This was a surprise as it looks completely over processed.

    So I decided to set the two parameters back to its default values.
    .ORI processed with Iridient and in the Detail panel, Edge Detail = 100, Texture/Micro Detail = 5. Image shot at Date Time: Mar 11, 2015, 6:21:19 PM.


    It appears that through this mapping process the artifacts seem to have been removed from the image.
    However, my eyes are not good enough to determine whether the down-mapped multiple shot images are any better than the single shot image.

    Luckily at Date Time: Mar 11, 2015, 6:21:30 PM, i.e. 11 seconds after the previous shot at Date Time: Mar 11, 2015, 6:21:19 PM I took another image that doesn't seem as badly affected by camera motion.

    Here is a crop of the image derived with CS6 from the .ORF file and mapped to 12288x9216.


    This is the corresponding image derived with Iridient.


    And this is the downsized complete image developed with Iridient from the .ORF file.
    With best regards, K-H.

    Re: OM-D E-M5 Mark II Pre-Order

    Now a fun shot. I am really amazed by what this camera, the E-M5 II, can do.



    I was far from any vehicular traffic and there was no noticeable wind.
    Please, let me know if you can detect any obvious or not so obvious artifacts in the high resolution versions below. TIA.
    The original image from Iridient was 12288x9216 in size.
    I then cropped it to 12288x6912. Then stepwise cut the linear size in half. Here we go.

    Very nice detail. The sweet spot seems to be between 20-30 MP based on the 50% downsize of the largest file. I didn't see any artifacts.

    They all look good. Was that "lucky" shot a 100% crop detail? What happened to the wooden ladders they used to have leaning against the cliff to give tourists access to the 2nd story dwellings?

    Thanks Carl. No, that's the entire image. But here is the high resolution version:
    http://winklers.smugmug.com/2015-03-...toContrast.jpg
    I would say the image is pretty much in focus and sharp, not much of any motion blur that I can detect.

    Of course, the wooden ladders are still all there!

    That EE-1 Dot Sight should be very useful with the 300/4 lens coming later this year.
    Just got the email from Olympus for the EE-1: Shipped Fedex 2nd Day.
    With best regards, K-H.

    Thanks Bart. Will do.
    I will try it on the turkey vultures when they return to their roost in the evening.
    As it's getting already dark then. not only is aiming a challenge but also AF with my OM-D cameras.
    Under those circumstances I never could get AF-C really to focus when the birds fly by pretty fast.
    However, AF-S seems to work quite well.
    So, it will be interesting to see what improvements. if any, the EE-1 will bring.
    With best regards, K-H.

    Re: OM-D E-M5 Mark II Pre-Order

    My first quick feedback for the Olympus Dot Sight EE-1 on E-M1 + M.40-150mm F2.8 + MC-14. The image below was shot with these devices.



    Well, the brightness of the illuminated red sighting circle can be adjusted and obviously needs a battery stuck in the right way.
    Then there are two adjustment wheels - left-right and up-down - so that what one points the red sighting circle at appears in the center of the image.

    To me this sighting device is a real help by being able to point the camera in the right direction.
    The challenge is with the pretty slow focussing of the OM-D cameras.
    Af-C is hopeless for my scenarios. AF-S focuses very slowly and then loses the focus in continuous shooting.
    I got the shot above by being able to point the EE-1 at the vulture for a few seconds before the camera was able to focus and take shots.

    I now have the EE-1 on my Nikon D800E + AF-S 80-400/4.5-5.6 VR lens. This system focuses really fast.
    So, as long as the subjects are large enough so that the EE-1 actually points the focus point at the intended subject then the right subjects are in focus.
    For tiny hummingbirds that seems to be a bit of a challenge.
    I am hopeful that for larger birds this won't be a problem.

    So, I give the EE-1:

    Does setting the AF target circle to its smallest size make S-AF work better or faster for birds against the sky in the M5.2?

    Thanks Scott.

    I assume you are referring to the square or rectangular focus area in the viewfinder and not the circular sight in the EE-1 that is always the same size but can appear stronger or weaker.

    I have played with the E-M5MarkII focus area just a little bit. My impression is that the smaller area is helpful to put the focus on a small subject and not the background.
    With a bird in the sky there is no background really. So, with a larger focus area one has a better change of getting the camera to focus on something, like a flying bird.

    My 2 cents. Please, let me know what your experience is. TIA.
    With best regards, K-H.
