Focus on Distant Subject

Same Composition, Different Focusing Points
In the warm light of late day, I ventured out to my collection of old trucks and ranching equipment. For this photo, I couldn't decide which should be the main focal point and, thus, sharply focused - the diagonal yellow subject or the distant wheel ... easy solution: I shot two versions! In this picture, I focused directly on the wheel, and then used a small aperture in order to make the grass at the lower right fairly sharp too. Note: Due to the extreme closeness of the foreground subject, it was impossible to get total front-to-back sharpness (deep DOF). Data: f/22; 1/6th sec.; 105mm lens; 100 ISO; tripod and cable release
In this second image (right), I switched focusing points. As shown, the subject was super-close to the camera, thanks to my macro lens. But, although it was impossible to get both foreground and background sharp, I still chose a small aperture (high f/number), in order to ensure crispness throughout the front subject. I'm not sure which version I like best, but I'm glad that I photographed the scene both ways!

Same Composition, Different Apertures
Photogenic government buildings can make great subjects ... when they're closed, that is! Normally busy, this stairway outside the front entrance to a courthouse made a fine subject for the soft overcast light on a weekend day. I used a telephoto lens - 105mm - to zero in for a tight composition, including a very close subject (green railing). Since I wasn't sure how much - or how little - Depth of Field would be best, I shot it two ways: at right, with a small aperture (high f/number) at right; and, below, with a larger aperture (lower f/number). It turns out that I like both versions! Data for More Depth of Field: f/32 for a fairly deep Depth of Field; 105mm lens; point of focus on close-up green railing; polarizer (to reduce glare and deepen colors); and tripod!
In Less Depth of Field, I wanted a narrow range of sharpness, in order to isolate the focused subject (railing) against a blurred backdrop. Because the railing is very close to the camera and I was using a telephoto lens, I needed to stop the lens down a little - to f/8 - in order to keep the entire railing sharp. A wider aperture would have made the background even blurrier (nice!), but wouldn't have kept the entire railing sharp (not so nice). Data: Overcast, f/8 for a shallow Depth of Field; 105mm lens; point of focus on close-up green railing; Polarizer (to reduce glare and deepen colors); tripod!
