I've seen different opinions on this, I'm curious as to what others do. Read something recently about photographers in medium format using f/13 and above in studio. I realize this has a lot to do with the equivalent DOF of a larger format, and also with the intended use of the image. An image destined for 16x20 obviously requires more retained details then one printed at 8x10 to maintain the same level of sharpness. In studio my general go to is f/5.6 on the crop sensor and f/8 on the full frame. That seems to give me a good balance between DOF, light power, and details in the image. Recently I've been experimenting with raising the power (and aperture), with the result that the skin on the face appears brighter, more translucent. Surprisingly I didn't notice significant increases in skin retouching as the shadows filled more decreasing how noticeable the blemish was. Any thoughts on this by other????
