    A few shots with the E-M5II and 12-40 taken on a walk in the park. No tripod, but I still got 40+ MP (actually 61 average before cropping) by shooting short high speed bursts and then stacking 7-12 raw shots from each scene in PhotoAcute3 to generate a higher res final image.

    Thanks Bart. I have already been using the 3.0.1 version.
    But the 3.0.0 version already supported all the E-M5 II files.
    AFAIK I now have the following choices for editing the hi res files.

    CS6
    CS6 with Olympus plugin
    Iridient Developer
    Capture One Pro

    RPP64 also can handle the hi res files.

    I have to gain more experience with the latest Capture One Pro to make up my mind which editor to prefer. But so far Iridient Developer for conversion with subsequent use of CS6 and Nik seem to work pretty well.
    With best regards, K-H.

    You can add the latest Affinity Photo Beta to your list of apps that will process HR ORF files.

    Re: Fun with Olympus EM5 Mark ii 40mp only

    A series of detail shots of an old boxcar taken with the E-M5II+12-40 lens on a tripod in HR mode. The ORF files were batch processed through Irident using default parameters with full 64 MP tif output to LR. No further adjustments or sharpening in LR. Images were downsized 50% and exported as jpegs to Flickr.

    It was very windy and cold when I took these shots and although I didn't anticipate any subject movement the first shot below reveals that a heavy chain was moved enough by the wind to create blur and artifacts.











    edit: I was able to repair the blurry, swinging chain in the first image by blending in the chain image from the ORI file.

    Grrreat rusty train running gear, but if you want to see some more of the rocky southwest, have a look at
    Olympus OM-D E-M5 Mark II: Exploring landscapes with 40 Megapixels | atmtx photo blog .
    (not my work, just a link). He's shooting jpegs. Also, over at the Kirk Tuck blog, Kirk describes doing still life shots of electronic components with the M5ii on a sturdy tripod and finding that floor vibrations were a detectable problem. He also went to WiFi shutter activation to further sharpen things. A commenter subsequently pointed out that one level deeper in the menu that sets up the HR is a control to set a shutter delay.

    Thanks Scott. The SW environment is ideal for HR landscape work with the E-M5II. The 64 MP tif files from the latest version of Irident Developer are very nice, thanks primarily to significant improvements in sharpening and noise reduction. I also process the ORI files identically to the companion HR ORF files and then use the ORI to mask out any movement artifacts when necessary.

    This picture is my favorite of the lot. I like the red colors and the round wheel contrasting against all the squared shapes.
    I think that I prefer the version where the chain is moving. It adds a little something to the whole, one can imagine the wind blowing..

    However that is just looking at my iPad : not sure how theses artifacts would do in a print.

    Sandy's AccuRaw Monochrome will also now process the HR ORF files from the E-M5II. Default output file size is 9274x6932 pixels. Nice option if you want high resolution monochrome files. Here is a sample image taken awhile ago and processed through AccuRaw Monochrome. Click for larger file that is a 25% linear reduction of the original.



    Two more from AccuRaw Monochrome with some toning.

    LR CC now supports E-M5II ORF and HR ORF files. Also, some nice new features for merging files to stacks, HDR, and panos. Here I used 3 HR ORF files from the EM5II + 75mm in LR CC to create a focus stack in Helicon Focus without having to use intermediary TIFS. Click for full size 64 MP image.

    Hi Carl,

    first, thanks for posting these examples
    Now that shot with the piece of wood is pretty clean, whereas the rock garden is very noisy.
    Also artefacts are found all over the image.
    Any thought what may have caused the difference between these two shots ?
    Low light ? Some wind ? Other processing ?

    Kind regards.

    Hi Bart,

    Thanks for the comments. The differences between the two images are lens (75 vs 12-40), aperture (f/5.6 vs f/8), and processing of the rock garden image included some contrast adjustment with Topaz Adjust. It is probably the latter that is causing what you refer to as noise and artifacts. There are no motion artifacts (diagonal line patterns) that I could see.

    Two more 64 MPx example files to play with

    My first tries, medium weight tripod, 4 sec delay before each shot:



    and a long shot -- a Moire tester



    The originals and various full size (30 MB) jpegs are all here.

    Other files: ...i.jpg means that I rendered the 16 MB first frame of the series. And ...OLY.jpg is the in-camera processed 40 MPx jpg that Olympus provides. The picture of the building has Moire on the window sun-grilles when viewed at 100%. It's faint but visible in the jpegs which I developed in Capture One or in the AccuRaw results from Sandy McGuffog, but it is strong and accompanied by a "mosaic" or "stairstep" artifact in the in-camera 40 MPx jpeg.

    Think about that for a moment. In the course of taking the 8 exposures, each pixel location has had all four of the Bayer filters in front of it for a single exposure (and the same applies to the second group of four shots, displaced by half a pixel-spacing in the x and y directions. So this has become in principle a Foveon-like image, with all three colors measured at every pixel. So why is there any Moire at all?

    Maybe I've got the wrong impression about where the chip moves for its 8 shots. Or maybe this is because, in order to allow fairly standard rendering programs, which expect to see a Bayer array image, Olympus has had to translate their lovely Foveon style image back into a virtual Bayer array with finer spacing, which can then indeed have Moire! Sandy tells me that the big 100 MB .ORF files are coded to represent a 64 MPx array of pixels with standard RGGB Bayer color filters.

    Hi Scott,

    Results are looking good. I downloaded your distant buildings ORF file and processed through both LR and Irident. Similar results to what you obtained with C1 and AccuRaw. Screen grab comparison below with Irident left and Lightroom right. Looks like a bit less moire in the Irident file, but some strange demosaicing artifacts that look similar to what I've seen before from Fuji X files.

    Scott, Carl,

    FYI, this is what the same section looks like processed via AccuRaw (at default settings)

    Re: Fun with Olympus EM5 Mark ii 40mp only

    This is just a test. Bookshelf at 2 m, 75/1.8 @ f/5.6. The full image:



    and an excerpt at full size (1200 pixels wide)



    The .ORF, and jpegs from the big ORF, the first frame of the 8 and one courtesy of Olympus are here.

    (The bookshelf slopes, not the camera.)

    scott

    P.S. I shot first at f/8, but there was a loss of contrast due to diffraction. From 2.8 to 5.6 was equally sharp. At 1.8, there was some loss of resolution, probably due to depth of field -- the books aren't lined up very well.

    Here's another stress test:



    It's a huge cemetery on the western approaches to Jerusalem. I may need to get an even sturdier tripod. This 8-shot HR composite was only slightly sharper then the first frame taken by itself (and of course the moving branches were not a problem in the individual frame).

    OM-D E-M5.2 12/2.0 @ f/8 processed in C1 8.2.2
    The original files will be found here

    Boathouse window. A relatively safe subject for the E-M5II in HR mode. E-M5II+12-40.



    Another window HR shot with embedded link to full size (52 MP) version.

    Here's one with enough detail to make 64 MPixels work a bit. First the easy-downloadin' version:



    and then a link to the RealThing.
    Note the topless runner in orange shorts appearing in two positions on the field.

    The full .ORF, the jpg created by Olympus, and jpgs rendered by CaptureOne 8.2.2 from the first frame and from the 64MPx composite can all be found here.

    Oh, 40-150/2.8 @f/5.6. Distance about 500-600 m.

    The "RealThing" however and looking at the scaffolding appears to be less crisp.

    Please, refrain from posting pictures larger than the max authorized of 1200 pix in the largest dimension. It is useless because everything is downsampled to 1200 pixels anyway. But this is a nuisance for those if us using ipads : the downsizing occurs on our individual machines and this freezes the ipads. Once there are several of those pictures in the same thread, the ipads become irresponsive : it takes several minutes to download and resample. The like buttons don't work as intended and the comment editor crashes or freezes.
    This isn't fair for other forumers and the benefit you hope to get isn't there anyway. I too measured 2400 dpi on the longer side of the picture you included directly in your post.

    I sharpened the full 64 MP jpeg as much as I dared. Viewed at 50% (down to 16 MP) it is crisper and clearer than the first frame seen at 100%, which doesn't always happen, if your tripod is a little old, or the wind is blowing. So I sharpened it twice as much (see P5240423 1.jpg) and now I think it looks pretty good at 100%, but I'll have to check it at home on a big screen to be sure there are no artifacts.

    scott

    P.S. Driving the sharpening slider in COne 8.2.2 all the way to the right works pretty well on this file.

    Here's a Moire-challenging shot, cloth flowers. First the whole frame, reduced beyond recognition to 1200 pixels width:



    and then a 100% crop:



    The full size versions (64 MP, 40 MP, and the first frame at 16 MP) are all here


    using the 40-150/2.8 at 150/8. Sharpened in Capture One 8.2.2 to 80 on a scale of 100.

    Well, with the site's new flaky software, I can often see my pictures at 2400 pixels wide. I was looking at stuff on an Android tablet the other night, and everything came down wider than 1200, because I had squeezed the frame width before connecting to the site.

    I'm really digging the 40mp shots. Two shot pano yielded this 8800x4500 shot. works well on long expo as well
