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.
