my camera takes RAW and JPG images at once. Of course both are shown in lightroom side-by-side. Is it possible to hide the duplicate image? E.g. only RAWs will be shown, but when clicking on it I can see the JPG version as well?
In Lightroom 4.2 there are some filtering features that enable the user to filter on file type as well as the number of stars and other characteristics of the image. I cannot give you a lot of detailed information because, frankly, I haven't used the feature extensively. I am primarily a Lightroom Classic user.
Good news. In 'new' Lightroom / "Photoshop Lightroom" / whichever nomenclature is canonical to represent the Lightroom application that's not 'Classic', this is doable. I also shoot RAW + JPG and found the duplicates annoying 😊
Upon clicking in the 'Search' field, a number of filter options come up. Clicking the 'Extension' button then selecting 'jpg' (or RAW etc.) hides all of the other images 👍🏻. Note that you do have to click the search field and not the Filter (funnel icon) button — the "Extension" filter isn't present in the quick-filter bar.
Adding the extension filter works great and totally satisfies my workflow. Hope that helps all!
