I've been using Aperture for several years now, and since APple will no longer be supporting ( ), I am now in the process of evaluating LR and C1 Pro as alternatives.
So far, C1 Pro seems to be coming out ahead in all areas from the management side of things to also the raw processing side of things (frankly Im stunned by how good the imported NEF files look in capture 1 compared to LR and Aperture). Im still trying to get a handle on importing and the differences between catalogs and collections, but I am really liking what I see so far with that program.
Downside so far is no integration of NIK software, and some features that I got used to in Aperture are not in C1 (such showing where the focus points are).
What are other Aperture users here going to switch to?
The way C1 works with NIK or any other editor is pretty easy.
Just right click on the photo, pick "Edit With"
Once thats open, just Click "Open With"
at the bottom.
If your third part app isn't on the list, you can find it by clicking "other".
Remember there are some settings you may want to change at the top, like whether you want it to be a Tiff or Jpeg.
I just tried it with Silver Efex Pro and it converted the RAW to a Tiff and opened it up in SEP. I made some adjustments then saved.
The adjusted file appeared in C1.
If you want to open the RAW file in another Raw convertor, right click and pick "Open With".
I hope that helps.
