How to export and import images while maintaining the resolution?

Hi there
I wish to export a figure with a given pixel resolution (i.e. Matrix size) to a format understood by Photoshop, perform a few basic changes, and import it again (using f.ex. imread), such that it has the same resolution upon re-import. Currently when I export a figure using print, imwrite or export_fig the figure returns with slightly less resolution upon import.
Does anyone know how to fix this?
Thanks in advance!

If anyone else was wondering: By chance, I just stumbled across a solution to this myself, when I read this recent blog on lossy/lossless image exporting:
