But there are a couple big problems with using Aperture now on Sierra:
1. The raw converter is provided by the OS, but Aperture is "locked" to using the raw converter from when it shipped. So even though the raw converter in OS X (er, sorry, macOS) has improved a lot in the past 3 years (it can be used in Photos), the one in Aperture has not. And raw converters have improved in the past 3+ years.
Bill, I don’t think that’s true. AFAIK, Aperture has never had it’s own RAW converter, it’s always used what the system provided. I’m not on Sierra yet, still using El Cap, but in Aperture menu -> About Aperture it says it’s using Digital Camera RAW 6.21, which dates from July 2016. And you can dig around using, for instance, the Info button in Activity Monitor, then look at Open Files and Ports and you’ll see the same Camera RAW 6.21 referenced. So what are you seeing that leads you to think it’s not using the latest in Sierra?
As for the rest of the discussion, I’d like to clarify what I said at the top, for whatever it did to send us off in this direction.
1) When I see the term RAW converter, I interpret that narrowly. For instance, Raw Photo Processor and AccuRaw are RAW converters, that’s all they do. Aperture and Lightroom do convert RAW, obviously, but they also do far more than that. To refer to them as RAW converters is a misnomer, IMO, since that’s only one part of what they do.
2) So just for the record, I largely agree with Bob, in that for my purposes Aperture (still) offers the best combination of u.i., conversion, editing, keywording, cataloging, and printing, and I’m still bummed that Apple decided to drop it. But I also agree with John if you pick any one of those areas, you can find other products that will produce better results, if you’re willing to put in the time to learn how to do it. And specifically in the conversion step, to address another comment; I wish my shots always came out so beautifully lit and perfectly exposed that I didn’t need noise reduction or highlight recovery. For some reason, the world refuses to cooperate.
Anyway, if there’s going to be any more discussion on this, can we please do without the personal insults?
