I have a lot of lovely images with Poppyseed, and here are two of them, from different occasions:
The first was shot near a mansion with a 24-70mm (at 70mm) ƒ. 2.8 to get a low depth of field, and the camera standing on the ground to eliminate as much of that as possible, and frame her against the darker grennery.
The second is a studio also shot with a 24-70mm at 60mm ƒ5.0
I tend to use 24-70mm for most of my work, except when I want an interesting bokeh or a very shallow depth of field.
Both uses natural light only.
