The reason for downloading the collection is Silver Efex Pro 2. I find that Lightroom is not that good for post-processing my scanned black and white files --- they come out a bit flat and they lack a rich tonality. I've been without Silver Efex Pro 2 since I upgraded the Mac's operating system to Yosemite, and I've missed using it for post-processing my black and white medium format negatives. Silver Efex Pro works well, but it is now part of a package, rather than a standalone software. Hence the download.
I have started exploring Analog Efex Pro---a film emulation program---to see what it offers. When people nowadays think of the film look, and when they go ga-ga over the film look, they aren't really going ga-ga over the look of film. They're fetishising a simulation of an idea. An implanted memory of something that didn't really exist. That's Analog Efex Pro.
I'm not interested in its gimmicks (eg., adding dirt and scratches to the image), but I am willing to explore how the various types of retro or aged looks would work with black and white medium format. Will the software add anything? Or should I just stick to using Silver Efex Pro?
