Cropping Tips

Minimize Pixel Loss

Crop to ratios close to your camera’s native ratio (usually 3:2 or 4:3) to preserve the most pixels. Extreme crops like 16:9 from 4:3 lose significant resolution.

Plan Your Crops

If you know you’ll need specific crops, compose with extra space around your subject. This gives flexibility without losing important elements.
