When trying to photograph detailed landscape photos, the natural inclination is achieve the greatest depth of field possible. Why? The detail resolved in a DSLR photography will exhibit much greater definition than a capture created by a cellphone or compact camera. The differences in medium may not be apparent until an image is displayed at its largest size.
Are there times when it is “okay” to intentionally limit the depth of field in a landscape view? Yes. There are no laws in art creation, and an artist does not advance in his/her field by conforming to the norm. The scene that I have presented here does quickly fade to soft focus. Why? Because I like it that that way.
