Examples

1. Optimizing Sony RAW Photos for Web Portfolios

Professional Photographer
Background
A photographer shot a series of portraits on a Sony Alpha camera in ARW format and needs to upload them to a web portfolio that only accepts standard image formats.
Problem
The raw ARW files are too large for web display and cannot be viewed directly in web browsers.
How to Use
Upload the ARW file, set the PNG compression level to 8 for a smaller file size, and specify a maximum width of 1920 pixels.
Example Config
Compression Level: 8, Width: 1920
Outcome
A web-ready, high-quality PNG image that loads quickly and retains the original photo's details.

2. Recovering Highlights in Sunset Landscape Photos

Hobbyist Landscape Photographer
Background
A hobbyist captured a sunset scene, but the sky highlights are slightly blown out in the raw ARW file.
Problem
The bright areas of the sky lack detail, and the colors look slightly muted.
How to Use
Upload the ARW file, set Highlight Recovery to 5, and increase Saturation to 1.2 to enhance the sunset colors.
Example Config
Highlight Recovery: 5, Saturation: 1.2, Brightness: 0.95
Outcome
A vibrant PNG image with restored cloud details in the sky and richer sunset tones.
