HDR Photography: Merging Exposures for Maximum Dynamic Range

Description

High Dynamic Range photography solves the fundamental problem of scenes that exceed the sensor’s single-exposure dynamic range capability, and this guide provides a sophisticated framework for achieving natural-looking HDR results rather than the oversaturated, halo-riddled images that characterise poor HDR practice. Bracketing sequence selection covers the number of exposures appropriate for different scene dynamic range widths, the exposure increment interval, and the camera settings required for consistent alignment across the bracket set. Lightroom’s HDR Merge function is evaluated against manual Photoshop luminosity mask blending for different scene types, with practical guidance on when the automated approach produces excellent results and when manual control is required. Tone mapping — the process of compressing the merged high dynamic range data into a displayable image — is addressed with emphasis on preserving natural-looking local contrast and avoiding the halos and colour shifts that signal over-processed HDR. Specific applications including interior architecture, real estate, landscape, and twilight photography are each addressed with tailored bracket and processing recommendations.
