Top Tips to Speed Up HDR Efex Pro
Use 16-bit TIFF files
When importing images for HDR processing, using 16-bit TIFF files instead of 8-bit helps maintain higher image quality and better tonal range, allowing the software to work with more detailed data.Optimize Presets and Settings
HDR Efex Pro offers numerous presets. Choose a preset close to your desired outcome, then fine-tune the settings manually for faster results. This reduces the time spent on adjustments while still achieving a polished look.Update Your GPU Drivers
Regularly update your NVIDIA or AMD drivers to ensure compatibility and optimal performance. Updated drivers often bring better GPU utilization, especially for photo editing applications.Avoid Ghosting with Manual Control
Use the ghosting correction feature when processing multiple exposures to reduce artifacts from moving elements in your photos. This is particularly useful when merging bracketed exposures.
