The "studio" setting didn't help me to get in the mood of listening either. Just thought of giving some honest feedback regarding the effort because I appreciate your motives.

However, don't forget about the "circle of confusion". Different formats have different "COC". This can help one be more accurate in terms of "acceptablly sharp" within the "DOF". Best, DM Brown Stephen-

Great video.

However, don’t forget about the “circle of confusion”. Different formats have different “COC”. This can help one be more accurate in terms of “acceptablly sharp” within the “DOF”.

Best,

As mentioned before a 0.001 mm circle of confusion is outside the realm of physics even in outer space, unless you have x-ray eyes you are right. i just wanted to exaggerate my point and just chose the smallest CoC available on the calculator. but, as most of my photographs are in the infinity-area (land- and cityscapes) i tested many focussing-concepts and only the infinity-concept gave me the results i wanted (and a lot of users around the web are reporting the same). there is also a nice video about different focussing-techniques (especially on a rangefinder): Focus and Depth of Field The Figital Revolution [...] [...] Zitat von SJP + 1 The original concepts are fine & there is no need to completely rethink the basics.

I think it will become clear that at infinity the distant objects are very sharp and that the near and middle objects are also acceptably sharp. All of the other info in the article is nice tech stuff to know but seeing a side by side that you just shot is the best proof. For a portrait at a standard working distance of say 5-10 feet I would use the point or spot focus method.

There is no real life example in that text, only scientific approach IMHO. Could you give an example of using this method( steps I need to take before shot) when making a portrait or a landscape. Please!!! I do not understand the infinity focus technique, although I read it several times.
