The easiest would be to change the ISO value. To "assist" the HDR merge program(s), you will then also need to adjust the exposure settings in the EXIF meta embedded in the TIFF files generated. Which can be applied to the raw processing. You can then merge these images in an HDR program to take advantage of the lightened shadows and darkened highlights.ĭcraw also has a highlight recovery option: -H Highlight mode (0=clip, 1=unclip, 2=blend, 3+=rebuild) This will create a series of TIFF images with varying levels of brightness as well as being 16bit linear Tiffs. Note it will probably take some messing around. I've used it for this purpose before, to "convince" the HDR merge programs to make use of the information. The 'dcraw' program allows you to specify a variety of options including the Gamma and Exposure level settings to apply to the output file. There is a Mac version for download from the site, the source code, and if you have HomeBrew installed, you can install it via 'brew install dcraw'. ![]() If you are interested in this, I would suggest getting 'dcraw' which is a command line RAW converter.
