  • High res shot problem

    Hello all.

    Just been photographing an original artwork with high res shot (EM5 Mk2) and have come across a problem. The bottom edge of the image seems a lot softer than the top edge (see images attached).

    I've run a test as a single shot on both my EM5 Mk2 and EM1 and both are sharp in all 4 corners.

    Anyone have any ideas what could be causing this?

    Thanks in advance

    Could camera ( sensor) be slightly angled to the plane of the art? Work

      Hi Ed

      The camera is perfectly square to the artwork. As I mentioned, I have taken single shots with exactly the same setup and they are sharp all over the frame.

        Can you share larger versions of a specific subject taken

        a. as a single shot jpg (at the best resolution)
        and then
        b. exact same target and camera set up ( No other changes ) but taken as a high res jpg shot

        Cant really tell from your attached thumbnails.

          Hi Dave, Unfortunately, I can't share the full images due to copyright of the original artwork. The single shot's I've taken are perfectly sharp across the frame.

          It's unfortunate that the EM1 doesn't have the high res shot, as that would have been a good comparison between the 2 cameras.

            OK I understand.

            Cant you try another target?
            Even a picture of some carpet, or some rough cardboard. If there is a difference it will show up.

              Hi Dave, If I find the time, I'll setup a different target, although may not be for a few days.

                Assuming you used a tripod, was the IS switched off?

                  In high res shot mode, IBIS is automatically disabled. I disabled it for the single shots.

                    OK. I've not yet tried HiRes mode. I didn't realise the IBIS switched off automatically. I suppose I should have realised given the way HiRes works.

                      Was it repeatable? Does it use electronic shutter or mechanical?

                        I read an article about the hi-res mode the other day, and it cited that the tripod really must be perfectly still and remote (wireless) release was ideal. There were a number of other significant caveats too (link below).

                        http://www.stevehuffphoto.com/2016/0...y-brad-nichol/

                        "..fact is pretty much the majority of tripods that photographers are using out there will be practically useless with HR mode. Trust me on this, even the slightest amount of movement will obliterate the advantage of the HR mode and most tripods move at least a little bit, especially those with little mass"

                        "Note, probably better than the cable release is to use the Olympus smart phone app to trigger the shutter thus eliminating any chance of induced movement"

                        It might all be something you are well aware of, but I found it an interesting read, in that the feature is hard to get exactly right!

                          Think that accounts for my trails on getting the moon on HR. At first I thought was the earth's rotation that caused the failure.

                            I took 85 in a row on a tripod and had no failures.....
