Examples

1. Optimizing Nikon Coolpix Photos for Web

Travel Blogger
Background
A travel blogger took several landscape photos using a Nikon Coolpix camera in NRW RAW format. They need to upload these photos to their blog quickly.
Problem
The raw NRW files are too large for web upload and cannot be viewed directly in web browsers.
How to Use
Upload the NRW file, set the JPEG quality to 90, set the maximum width to 1920 pixels, and slightly increase saturation to 1.1 for more vivid colors.
Example Config
Quality: 90, Width: 1920, Saturation: 1.1
Outcome
A web-ready, vibrant JPEG image under 2MB that loads quickly on browsers while retaining metadata.

2. Recovering Highlights in Overexposed RAW Shots

Amateur Photographer
Background
An amateur photographer captured a bright outdoor scene, but the sky highlights in the NRW RAW file are slightly blown out.
Problem
The sky details are lost, and the overall image looks slightly dark in the shadows.
How to Use
Upload the NRW file, set highlight recovery to 5 to restore sky details, and increase brightness to 1.2 to lift the shadows.
Example Config
Highlight Recovery: 5, Brightness: 1.2, Quality: 95
Outcome
A balanced JPEG image with recovered sky details and improved shadow visibility.
