Assuming this is a Pentax DSLR, to do open aperture metering you'd have to be using an A, F, FA or DA lens. You could set the mode selection to any setting other than M or B. If the lens has an aperture ring, you'd set the ring to "A," then choose your aperture or shutter speed using the camera's dials. The camera would then meter with the aperture open and you would be free to focus and shoot. Because the Pentax DSLRs don't have ....uh....certain hardware, you can't do open aperture metering with M or K series lenses.
