Ok so i imported a RAW photo with lots of noise from my Nikon D3300.
Touched up the White balance, Highlights and Shadows.
Applied some extreme DeNoise
Then Applied Sharpening
Developing took a couple of minutes and seemed to hang my 2011 MBP with the colour wheel. Bearing in mind i have 16Gb of RAM and i'm running on a Kingston SSD drive. The photo however was stored on an external thunderbolt drive.
Everything else was very fluid and responsive.
Uncompressed the resulting JPEG was 22meg, at 90% the resulting JPEG is just over 3meg.
Both images have been cropped from the original due to it's rather large dimensions :unsure:
