Export from Lightroom to ISO100

Recommended export settings

Choose export size for the work

• A 3:2 landscape at 2560px on its long edge is about 2560 × 1707px. A portrait at the same long-edge setting is about 1707 × 2560px.
• A 2:3 portrait needs about 3840px on its long edge to be 2560px wide. Allow more source detail for a tight crop. Public display still follows the Free 1600px or Plus 2560px width limit.
• Use quality around 85 to 92 instead of 100. The visual difference is usually negligible on the web while the file can be much smaller.
• Avoid exporting an already compressed social-media download. Export directly from the edited master.
