Thanks for your contribution to the previous post. They have been most helpful.

So how much sharpness or depth of field is enough? I assume f64 means sharpness throughout the whole photograph. Supposing I made a photograph with most of the main subjects tack sharp and had left the background just out of the depth of fi eld (bokeh, I suppose). Would that be acceptable by your definition of sharpness (I'm not talking soft focus here)? Also, with the Ansel's style of cold/neutral toned, deep black prints that many of us had stayed on as a "tradition", how wo uld it matter to you to make a switch to slightly or extremely warm-tone paper? How about semi-matt as oppose to glossy surface (surely we don't see a gloss in front of the image that we see in real life)? And there are non-traditional proc esses, that by nature of the process and paper stock used, sharpness is compromi sed to some extend. Can we find a balance between truth (defined as f64) and tas te (defined as artistic judgement)?

Many Thanks,

Aaron
