Capture One Pro 7 works for me a couple of week now. Its running as fast and as stable as the former versions, it only crashed once when I cataloguing over 3TB of pictures on one internal-, and three internal drives.
As it crashed, a message came to life asking what I did at the moment things went wrong. The message was send to Phase One for diagnosis. Very well programming!
I start with engine 6 for standard. So I could make duplicates and compare pictures by ´developing´ the original with the version 6 engine and the duplicate with the 7 engine. I say, to my liking, the engine 7 makes really better pictures. I´m conviced, now I use standard the 7 engine.
I regret that my old 32bit computer still has to do with Capture One Pro 6. But then, its my spare.
Shamael: Capture One, despite being one of the best workflow software I ever used, sucks. At every update of a few new cameras, they sell you an expensive update. The latest cameras that just came out are not contained, buy the soft now and in 3 month you buy another expensive update to see you camera raw file being opened in it. PS sucks with their limited updates of ACR and they force you to buy a new version and a new computer at every version when they stop supporting or updating the software. Latest version of ACR does not work in PS CR5, you have to get version 6 and here the memory overflow is that big, you have to change to the highest level in computer technology to be able to use it.
If I consider the' price paid for any of those software, I expect at least to be able to get updates a year after the new version comes out. PS sucks in this matter and C1 is a real mess, a money sucking crap in my point of view.
In fact C1 provided with version 6 over 2 years quite a lot of free updates. Not only to repair small bugs but camera updates were also included. Better stick to facts and not to unjustified emotions.
