This is more of an out and out rant, quite a long time in the making, than a question or any sort. Why does Apple insist on changing the default RAW processing every time they issue an upgrade for Aperture 3? Generally speaking, the change is fairly minor, and quite easy to adjust to, but no recently upgrading to v3.5.1 - wow, I'm blown away, and thats not a good thing... On uploading EM5 files to Aperture they look great - great, accurate colour, good balance between noise control and detail retention, good dynamic range and nice transitions between highlights and shadows. In the past this has been how they've stayed, Aperture 3 seemingly willing to leave the files essentially as-shot and thus leaving me to work on subtle edits to achieve The Look. The EM5 does a great job in-camera and for me RAW processing has always been about tweeking. Not now though, by the time it's finished processing the files have been butchered. Massively oversaturated, brutal clipping of the individual colour channels, especially red and blue, terrible colour noise, terrible skin tones, terrible shadow/highlight transitions, the list goes on. I've spent a month trying to work out a general default preset to use as a base and I'm getting no where. Frankly I'm tired of having to work out the basics on every single file I use. I've been resisting the call of Lightroom for a while now but I'm over it - Apple I'm done.
