The amazing thing about the great outdoors, when it comes to photography, is the endless possibilities that are presented before the person behind the camera. Different lighting sources (sunlight, shadow, cloud, flash) and the ever-changing backdrop (or should I say background). And on top of that, I don't know anyone who would rather stay indoors when beautiful weather is calling your name.
The cherry on top has got to be the natural look your subject seems to look outdoors. Coincidence? I don't think so, I mean there's a reason why they call it 'natural' look... because it is cones from the fresh outside. I so I believe, in my vast knowledge as a photographer (personal joke) the only essentials you need to create stunning photos during anytime of the day are: 5 in 1 reflector, a flash mounted on your camera and a willing pair of hands. That's it. You can circumvent around harsh midday sunlight with your reflector acting as a diffuser and using the flash unit to create depth in your portrait.
So now te questions is not so much which scenery or garden to pick from but rather how much time do I have in taking breathtaking pictures outside.
Happy shooting!
