Mastering Lightroom Export Settings: The Difference Between Good and “Wow”

I used to be that person. You know the one—I’d spend two hours color grading a portrait, nail the skin tones, get the highlights just right, hit export with default settings, and then wonder why the photo looked flat and lifeless on Instagram. Turns out, export settings aren’t just technical minutiae. They’re the final boss between your vision and what everyone else actually sees.

Let me walk you through what I’ve learned about keeping your edits intact during export, because this matters more than you think.

Color Space: sRGB vs. ProPhoto (And Why It Matters)

Here’s the thing about color spaces that nobody explains clearly: sRGB is your friend for web content. ProPhoto RGB captures a wider range of colors, but most browsers and social platforms don’t know what to do with it—they’ll compress it anyway, so you’re just creating an unnecessary middleman.

When I export for Instagram, web, or client proofs, I always choose sRGB. It’s smaller, it’s consistent across devices, and it looks exactly how I intended it to look. If I’m archiving a master file or preparing for print, I’ll use ProPhoto RGB instead. Different tools for different jobs.

Resolution and File Size: Finding Your Sweet Spot

I learned this the hard way: bigger isn’t always better. Exporting at 300 DPI for web is like bringing a tuxedo to a beach party—technically fancy, but totally unnecessary and bloated.

For social media and web galleries, I export at 72 DPI with a long edge of 2400-3000 pixels. This keeps file sizes manageable (usually under 2MB) while maintaining enough resolution for detail. For print work, I bump it to 300 DPI because printers actually need that information. The math changes the game.

Sharpening: The Secret Nobody Talks About

This is where I see most people mess up. Lightroom’s export sharpening is different from the Develop module sharpening—and you need both.

In the Export dialog, I use the Sharpening section under File Settings. For web images, I set it to “Screen” with an Amount of 80-100. This adds micro-contrast that accounts for screen compression and makes colors pop without looking over-processed. For print, I switch to “Matte Paper” or “Glossy Paper” depending on the final output, with higher amounts (120+).

The before-and-after is honestly shocking. It’s the difference between a photo that looks good and one that makes people stop scrolling.

Color Grading Survival: Don’t Let Compression Kill Your Work

Here’s my non-negotiable rule: always export as JPEG with a quality slider set to 80 or higher. This is where I see people lose their color grades entirely—overly aggressive compression destroys the subtle color work you spent time on.

I actually test this. I’ll export the same image at quality 75, 85, and 95, then zoom in and compare. Honestly, 85 is usually the sweet spot where the file size is reasonable but the color integrity is still there. Anything below 80 and your greens start getting weird, your shadows crush, and all that careful color grading work becomes invisible.

Metadata: The Boring Essential

Toggle on “Include Copyright” and “Include All Metadata” before you export. I tag every export with my name, the shoot date, and location. It’s not exciting, but it’s protected my work legally more than once, and it’s saved me hours searching for specific shoots.

The Final Test

After I export, I never immediately upload. I close Lightroom, open the exported file fresh in a browser or preview app, and see it with completely fresh eyes. That’s when you catch the color cast you missed, or realize the contrast needs another pass.

Export settings aren’t sexy, but they’re the difference between “nice photo” and “how did you make that look so good?” Trust me on this one.
