Can PNG files be used for bracketed HDR?

Yes, a PNG sequence can be used for an HDR-style workflow if the images are separate exposures of the same scene and stay organized in the correct folder.

How should a bracketed PNG sequence be organized?

Keep one room or scene per folder, include at least two exposures, avoid mixing different rooms, and keep filenames in a clear capture order.

Does Lumaro support PNG bracketed images?

Lumaro accepts JPG, JPEG, and PNG bracket images in its folder-based local processing workflow.

PNG Sequence Bracketed HDR Workflow

A PNG sequence can be used in a bracketed HDR workflow when the files are separate exposures of the same real estate scene. The important part is organization: one room per folder, enough exposure range, and a clear path from merge to review.

01 PNG sequence Keep the bracketed exposures for one scene together.

02 Align Correct small frame shifts before exposure blending.

03 HDR base Blend useful highlight and shadow detail naturally.

04 Review Adjust and export the finished listing image.

What "PNG sequence bracketed HDR" means

In this context, a PNG sequence is a set of PNG images captured or exported from the same scene at different brightness levels. A darker frame holds more window detail, a middle frame gives the room reference, and a brighter frame can help recover interior shadows.

The sequence should not be treated like a video frame sequence. For real estate HDR, each file is a separate exposure that contributes different light information to the final image.

How to organize the folder

Use one folder per room or camera angle.
Include at least two exposures; three or more is usually better.
Keep filenames in a clear order when possible.
Do not mix PNG files from different scenes in the same folder.
Review the final result for ghosting if the camera moved between exposures.

PNG versus JPG for bracketed real estate edits

PNG can preserve clean graphics or exported image data without additional JPG compression, but it may create larger files. JPG is more common for camera capture and real estate delivery. The best choice depends on how the brackets were captured or exported.

Lumaro supports JPG, JPEG, and PNG bracket images, so the workflow can start from either common format when the files represent a valid bracket set.

Where Lumaro fits

Lumaro uses a folder-based workflow. You select the bracket folder, process the scene locally, review the Natural HDR Base and Premium Launch Result, adjust if needed, and export. This makes it suitable for organized PNG or JPG bracket sets from real estate interiors.
