[Exporting images for Retina]

I am trying to get the workflow down for saving images for Retina displays. In Photoshop, you would place a 3x larger image in your file as a smart object sized down to 1x. This would preserve the larger dimensioned image for exporting for Retina images.

 

Since AP does not do smart objects, when you go to export your image @2x and @3x from a @1x size, how does the export compensate for the larger size Retina images? It might make sense to place a @3x image size and then downsample to @2x and @1x for exporting but I don't think AP does that?

 

I'd like to get a workflow down. Can you advise?

 

Thanks much and a super great product!
