LevelB Posted December 28, 2016 Share Posted December 28, 2016 Prior to creating a new Exposure Stack or HDR Merge, is it necessary to remove noise, and then save in a lossless format such as .tiff? Thanks! Quote Link to comment Share on other sites More sharing options...
Staff James Ritson Posted December 28, 2016 Staff Share Posted December 28, 2016 Hey Fred, You can optionally pre-process raw files and save them as JPEGs or TIFFs. This gives you two advantages: 1) Faster processing of images since Photo doesn't have to decode each raw before merging/stacking. 2) External handling of raw processing if you prefer the results that other software offers (for example, Photo doesn't have camera picture profile support at the moment; emulations of in-camera profiles like Vivid, Portrait, Natural, etc). You don't have to pre-process though. Just start a new HDR merge and add your raw files. Noise reduction is already checked, which will denoise the merged result. You may want to experiment with the strength though, as I've found the default value of 40 can be a little aggressive. 10-20 seems to work better for most low ISO HDR work. Hope that helps!
