Satisfied with the photos taken during the last photo walk, I’ve decided to convert most of the photos taken this time around to black-and-white as well. Although I’ve developed black-and-white and color photos side-by-side many a time in the past and always felt that the monochrome mode was faster, I’ve never observed such an extreme speed difference between the two modes in Sigma Photo Pro, like during today’s post processing session. This time around the RAW converter appeared downright fast in the monochrome mode, which perplexed me quite a bit, because the application isn’t known for its speed. The difference was especially large while exporting X3Fs as 16 bit TIFFs. SPP 6.2 was able to save BW TIFFs over 60% faster than color TIFFs. We are talking about a difference between 8 and 21 seconds on my notebook with a dual-core i5 4200U CPU, 8 GB RAM and a slow notebook hard drive. I, however, didn’t run a test on my desktop PC with a quad-core CPU and a SSD.
Now I’m wondering whether SPP was always that much faster in monochrome mode – actually since version 5.5, which is when that mode was introduced – or whether it has gotten that fast with one of the 6.x.x versions?
