Big open windows with north light or overcast day with perhaps some flash fill and good natural post processing…..
Overcast skies with great fill and good lens selection along with good natural post processing.
If you look thru her blog, you will notice a lot of her work is VERY consistent. I would bet that this is due to her knowing her limits to natural light. Most so call "Natural Light" photographers are re-active to a lighting situation -vs- being pro-active. Notice that you picked ALL images that were shot on overcast days and most of her work "that she shows" were shot on overcast days. There are virtually no images shown on bright sunny days unless it's at dusk or once the sun has already gone down. So does she know ahead of time (weeks or days) what days will be sunny and what days will be overcast? Of course she doesn't, but what she does do is ONLY SHOW you her best work which just happens to be on overcast days. So, not only does she know how to control her lighting (on overcast days) but she tops that off with proper natural post processing as well as only knowing to show her best work that she has shot, not every work that she shoots…..
