These are shots I took in and around Pasadena(San Marino, aka The Huntington, is just south of the eastern portion of Pasadena) last Saturday. All of these shots were trying a different technique that I’d not used before, mainly different filters on the cameras.
Focus Stacking.
This is a demonstration shot of the focus stacking technique(one reason why the branch is sticking into the frame). Focus stacking involves shooting multiple shots as different focus and then putting them together in Photoshop(or another program).
Technical Explanation about Depth of Field(tl;dr)
The aperture on a lens controls how much of a photograph will be in focus(if it’s open all the way(a low f number), the distance that will be in focus is short, and if it’s smaller(a high f number) the distance that will be in focus will be greater). Shooting with a wide open lens lets in more light(good for astrophotography) and the focus is sharper. So shooting multiple shots at a wide aperture refocusing at each distance will produce a sharper shot. Fortunately my camera has software that does this for me.
