Hello refsvik and welcome!
I don't know if Autopano will be XGrid aware, even if a network render mode is already envisaged for another declinason of the product.
For now, autopano Pro already support RAW files as input, using a straight conversion, leaving image untouched (no NR / CA reduction / sharpen / color profiles).
16bit Tiff from your favourite RAW converter is an alternative.
About Aperture : I saw that all files 'imported' in Aperture are enclosed in a single file ( in the review at http://arstechnica.com/reviews/apps/aperture.ars/3
). I think it's bad, bad, BAD !! no.. just kidding.. that's EVIL !!!
I think users would be crazy to trust such a bad thing because what appends :
- Users are locked ( I cannot import my files in other apps
- Users are locked on this particular raw developpement software ( one of the big plus of RAW is that you convert files with one or another software, depending the strenght of each particular raw converter.
- Users will lose their work if Apple cancel support of Aperture ( probable scenario : the new Adobe Lightroom kill Apertur sales, Apple kills Aperture )
- What about file corruption.. and backups ?
Did i already said.. EVIL !
Use standard formats and never allow software (or hardware..) companies to lock your work in a closed black box.
