Thanks for the example photo . It made me investigate further rather than just put up with it. To clarify, when I view pictures exported from LR (using old & new laptop) on my new laptop they both look much darker than the same photo processed from camera and displayed on my new laptop. I was digging around and found another thread which made me check my camera settings and think It mentions the cause of the problem. EM-5: Gradation Auto or Normal?: Micro Four Thirds Talk Forum: Digital Photography Review "Auto gradation affects exposure, so while you won't see the shadow lifting part if you shoot raw and use Lightroom or other non Olympus software, you will see a darker exposure (about 1/3 stop darker). Not really a problem, but you will see people complain that their camera tends to 'underexpose' because they think auto gradation has no affect on raw shooting." I tested with the below pics ( not the greatest to show the issue but you can see the effect ) Pic below taken with auto gradation. LR natural left & JPG Natural right (brighter) Pic below taken with Normal gradation. LR natural left & JPG Natural right (very similar) So I can now use Normal gradiation and the pictures will match the Olympus colours. Thanks again for all the suggestions. TIL not to use autogradiation.. Guess I must have changed the setting at somestage... ... View more

I tried the below. Changing the display profile and it didn't make any difference that I could see. I actually forgot to note the default profile so have left it on the adobe one. The only colour profile (Srgb adobe rgb) or I could see was for exporting the image and I can see the darkness prior to exporting so left srgb. Its srgb on both LR & Olympus Viewer  I'm using the Natural camera profile in both LR & Olympus Viewer. Went back to my old laptop, reset LR and exported the same RAW file and viewed on my new laptop. The RAW file exported (Natural profile - no other changes) on my old laptop and new laptop were identical when viewed on my new laptop. Both a lot darker/ more contrast than the RAW file exported with Olympus Viewer. I`ve changed some settings in lightroom to try and match the Olympus viewer profiles. I think Lightrooms Natural (which should be a match for the Olympus Natural one) camera profile applies a lot more contrast & darkens RAW files compared to Olympus natural profile. It looks like my new laptop's display also does display more detail which initially helped confuse matters and  exaggerated the difference but I can still the difference in the sample photos (see the visible fence in sunset view)  when using a different monitor (at work) . Many thanks for the suggestions, If there's anything else I can try let me know. Otherwise, I`ll keep using LR and tweak the default settings to make it more like the Olympus colors I guess. ...

Thanks Axel, Ive tried to reset the preferences but it makes no difference. I checked this as I initially increased exposure +0.2 and it then reset back to 0 when I reset the prefrences. No, my monitor is not calibrated, however, the new laptop is a higher quality screen and better resolution so this may explain why I'm seeing such a difference now? I forgot about the colour profiles & will check when I get back home  That may be it. Hamish ... View more
