Today is hopefully a brief follow-up regarding the Aperture 3 curves tool along with some other connected bits. First off a working method. Due to the unique property of all the original tonal information being available within Aperture 3's curves tool rather than some truncated version I happen to choose a specific working method out of convenience. Specifically I will use the exposure control to boost exposure and then the curves tool to reshape the output response to my particular desire of the moment.

Here's the original post, follow-up Part I, Part II, Part III and finally the new one, Part IV.
