Further update: It looks like it works. The impression that it is not updated changing from 2.8 to f1.8 and back and forth was that I didn't notice the small changes in the background, because, when you start out, the background is sharp, and I immediately associated it with the default values that are set in the panel when you come to that web site, which is not true.

Thank you for the comment.



I do not understand well though I confirmed.

It calculates with JAVASCRIPT, and this program switches, and displays the image.



I think that the figure of Bokeh of subject 2 and Bokeh of background is accurate.

However, the image is not in strictness because the image of the background has switched about 100 kinds.

It seems to me, that this DOF-Calculator might need

some improvement ... at least, if I use the numbers

and settings it starts with (7D,50mm,f/2.8,2.5,4,10)

and then click "calculate", it does absolutely nothing.



Also, if I change the settings to something reasonable

and then click calculate, absolutely nothing happens.



The only visible reaction is when I click the "reset" button.



So, for now, I will stay with the wellknown ...

[url="http://www.dofmaster.com/dofjs.html"]http://www.dofmaster.com/dofjs.html[/url]

... which at least does what I ask.



So, it seems, there is always a bit room for improvement.



Just my 2cts ... Rainer



PS: I should add, that the browser in use was a Firefox 3.6.8

with javascript enabled.

The DOFMASTER is not all that clever. If you calclate in feet, the C of C remains metric. It would have been .03mm = .00118".
