Most of the wildflowers were finished when I visted Strathcona Park on Vancouver Island, BC, but I did make this image of a Tiger Lily.
To make this image, I set my camera up on the tripod with my 70-300mm lens. Normally you would have to be at least 5 feet away from the subject to focus with that lens. But I added a 500D close-up filter to the telephoto lens which allows a shorter focusing distance.
Of course a dedicated macro lens would be better, but I don’t have one of those.
With the 500D close-up filter attached, the depth of field is razor thin. This image was made at f/16 so I could get both the stamen and the entire petals in focus.
