While usual HDR technique involves fusing exposure bracketed images into a HDR image with further tone mapping, HDR can still be applied to a single RAW.
A RAW image contains higher dynamic range than a JPEG (or any other 8-bit format) can contain. Therefore, it's a good idea to use tone mapping for RAW-to-JPEG conversion to preserve the details available in RAW.
PhotoAcute's Tone Mapping workflow allows single-RAW processing. But PhotoAcute is still mainly a stacking application, therefore we have decided to release a lightweight application intended solely for single RAW HDR:
HDRAW.
HDRAW is a simple yet powerful tool dedicated to a single function: preserve details while fitting the image into 8-bit (8 stops) dynamic range. It can be used as a substitution for RAW converters, providing a highly accessible one-click conversion of RAW photos into stunning images with vivid colors and rich detail.
Good news for registered PhotoAcute users: You can use
HDRAW for free, it accepts PhotoAcute 3 registration codes.
Good news for those who have not yet bought PhotoAcute:
HDRAW is available at low introductory price and comes with a complimentary promo pack including a discount coupon for PhotoAcute.
