Hello, Heather......so pleased to hear you are enjoying this thread.
I suppose to answer your question; we would need to know your OH's level of skill or willingness to go further into it.
There three basic types of camera, each will do what you require with varying degrees of accuracy.
Compact cameras are mainly point 'n shoot cameras, although many of those at the higher end are capable of taking stunning pics.
DSLR cameras are those chosen by keen amateurs and professionals....these have interchangeable lenses and are the most expensive & complicated.
Bridge cameras are a kindda midway house between compact & DSLR.
My choice would probably be:
Compact Canon PowerShot SX500
DSLR Nikon D3200
Bridge Canon PowerShot SX50HS
There are of course very good camera phones, which I know absolutely nothing about.
It's a starting point, but I'm sure others will have good suggestions.
PS. IMHO Canon & Nikon make the best cameras.
