Here is a classic technique to "maximize" depth of field (DOF) using hyperfocal. Hyperfocal works well for wide angle lenses (35mm and wider) with a DOF scale.
The image below was shot hyperfocal at f/5.6 using a 35mm Summilux ASPH lens. Notice how the image looks sharp from foreground (the subject's face) to the background (buildings behind arc).
How to focus using hyperfocal:
Here is a simple technique to "maximize" depth of field (DOF).
The image below was shot handheld and wide open at f/1.4 using a 50mm Summilux ASPH lens. Notice how the Zumba instructor (on the right) and the students (on the left) both look sharp suggesting a really "deep" DOF?
The scene was dark and the subjects were doing a zumba. It was a no brainer that I have to shoot wide open at f/1.4 to get any usable image. I first tried 1/60s but found that insufficient so I went faster to 1/125. The final exposure used was as follows:
I then proceeded to shoot two images: one with the focus on the instructor (right); another, on the students (left). Both images were shot with the same exposure and processed exactly the same way (i.e., with the same adjustment settings). The final image is therefore a composite of these two images using masking technique (I used Perfect Mask).
Here is a simple trick to put "motion" to a still picture of a moving subject:
Compare at the two compositions below:
Shooting at high ISO can yield usable images if shot under the right condition. This is my favorite recipe for a successful high ISO photography using available light:
The following images were taken during a gathering at Riddhi's house in Clifton, NJ. All shots taken with a Leica M9 and a 50mm Summicron at ISO 1600 wide open at f/2. For moving subjects (people especially children), I would set the shutter speed to at least 1/45s to 1/60s.
Another picnic on another nice summer day hosted by Will Waterfield and family at their residence in Cornwall, NY. All shots taken without flash or reflectors using Leica M9 and 50mm Summicron.
