A-Depth is A-OK
Certain Canon cameras, including the T1i, offer an A-Depth mode. When the camera is set to this mode, it "sees" all the elements in the scene and picks the best focus point for good depth-of- field. It's an A-OK mode for quick snapshots.
For max depth-of-field for scenic photographs, here is what I do:
1) Use a wide-angle lens;
2) Select a small aperture;
3) Set the focus 1/3 into the scene.
I photographed this biplane at the Old Rhinebeck Aerodrome in Upstate NY. A great place for fun - and fun photographs.
The top photo is the straight shot. I created the bottom photograph using Topaz Adjust. See my plug-in site for more info - and how-to tips.
Make pictures,
