bobmcg Posted March 21, 2018 Share #1 Posted March 21, 2018 Advertisement (gone after registration) Has anyone noticed a fall-off in sharpness when converting from RAW to JPEG in Lightroom for web posting? The sharpness on the Q is nothing less than amazing but I'm noticing in Lightroom that when I export from RAW to JPEG and downsize for web posting, I seem to see a lessening in the sharpness of the final output. To be clear, the photos are very sharp in RAW format but lose something when I export. I've never seen this before with Nikon and Canon. Thanks in advance.

marchyman Posted March 21, 2018 Share #2 Posted March 21, 2018 There is a output sharpening setting in the export dialogs in lightroom. How is yours set? Link to post Share on other sites More sharing options...
bobmcg Posted March 22, 2018 Author Share #3 Posted March 22, 2018 It's set at "high" for "screen." Link to post Share on other sites More sharing options...
frame-it Posted March 22, 2018 Share #4 Posted March 22, 2018 and what file size are you exporting ? if the raw is 30++mb and converted jpg is 500kb it can tricky to get a sharp image as its heavily compressed..and many web forums re-compress the images as well Link to post Share on other sites More sharing options...
jaapv Posted March 22, 2018 Share #5 Posted March 22, 2018 Still, the downsizing will lose sharpness. One of the reasons I use Photoshop for postprocessing. Much more control. also for sharpening. Link to post Share on other sites More sharing options...
bobmcg Posted March 22, 2018 Author Share #6 Posted March 22, 2018 I'm going to 1,300 kb, the maximum size for the website. I might try Photoshop. Link to post Share on other sites More sharing options...
beez Posted March 22, 2018 Share #7 Posted March 22, 2018 (edited) Advertisement (gone after registration) I'm going to 1,300 kb, the maximum size for the website. I might try Photoshop. When making that big of a reduction, it's better to use Photoshop and apply some "unsharp mask" filter to the photoshop file before making the jpeg. First, resize the dimensions of the file (for instance: from 6000px wide to 1280 px wide or whatever works for you), then add the unsharp mask filter to the result. Unsharp mask is in the filter menu then go to sharpen - it's the bottom one. Then do a "save as" to make a high quality (#11 or 12) jpeg. Unsharp mask is the best way to sharpen pictures without looking fake or adding to jpeg compression artifacts in the pictures. - it finds the edges of things in the picture and sharpens them using contrast - the regular "sharpen" commands sharpen the pixels, and looks terrible. You don't want to sharpen a jpeg file after it has been compressed or already made. A little unsharp mask goes a along way, but you'll need to experiment with it to see what works for you. Here's a tutorial on the unsharp mask filter: https://helpx.adobe.com/photoshop/atv/cs6-tutorials/sharpening-an-image-with-unsharp-mask.html This is for CS6 - but it works the same way with CC.
