Does she do photos professionally? The most important thing for anyone photo editing should be the screen, nothing worse than having a so called 'performance' laptop only to be working on a poor FHD screen and get poor colour accuracy (IPS does not mean that it's a good screen, and in fact can be far worse than a TN). I would highly recommend
against the one above, you need at the bare minimum 90% srgb as a photographer(and you should aim be towards 99% adobe rgb), the one above is a horrible 60% srgb. How can you reliably edit photos when half of the colours cannot be reproduced by the horrible screen? These sub 1000$ laptops are very poor for photo editing purposes with the screen usually being the biggest drawback.
Get either the Lenovo X1 carbon, or X1 Yoga (carbon is a normal laptop and slightly thinner, yoga is a 2-1. They go on sale all the time at 30-40% off on the EPP site and you can get one in the 1500-1800 range.
This meets all your criteria, and this is what I got for similar reasons. I got the X1 Yoga with the HDR 1440p screen because it doubles as a tablet which is great for wedding presentations (and great in tent mode for watching movies in bed!). You can also edit direct on the screen which is a big plus for photo editing.

Macbook, Surface are also decent options, but have drawbacks as well, I considered the Surface Laptop but it's always a generation behind and has some really awkward design choices. Macbook performance per dollar is pretty poor.
