DFC Computer - taketoshi ikegami - 07-26-2010 DOF (Depth of field) Computer http://kingfisher.in.coocan.jp/boke2/bokekeisan2e.html I made DFC Computer. In the portrait, the important bokeh is understood well. Please use it. The link is free. DFC Computer - Rainer - 07-26-2010 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. DFC Computer - Sibbi - 07-26-2010 Yep, I have the same Problem - using FF 3.0.17... Bye Sebastian DFC Computer - taketoshi ikegami - 07-27-2010 I'm sorry very much. I am confirming operation with IE8.0, firefox3.68, and safari5.0. However, I who had remained Japanese in the program because of the comment corrected it. I'm sorry, could you try again? http://kingfisher.in.coocan.jp/keisan.html http://kingfisher.in.coocan.jp/boke/bokekeisan.html Will you also operate these?

I tried all three links again ... the first remains unchanged for me... the latter two have each and everything covered in strange characters ... I assume it would be japanese signs but my browser is unable to display them. (The image of the lady has improved a little in the last link though ;-) ) My suggestion is, you download firefox in an english version and install it parallel to your standard japanese version (which should be possible if you select user defined settings when installing). Then you can retry most things directly. Regards ... Rainer DFC Computer - taketoshi ikegami - 07-27-2010 I tried advising in firefox English version. This program did not move. Two byte characters other than the program were removed, and it came to move. Thank you. http://kingfisher.in.coocan.jp/boke2/bokekeisan2e.html DFC Computer - Rainer - 07-27-2010 [quote name='dai123' timestamp='1280217424' post='1327'] [url="http://kingfisher.in.coocan.jp/boke2/bokekeisan2e.html"]http://kingfisher.in...kekeisan2e.html[/url] [/quote] Now, this works ... if your calculation of the blur is correct, this is a definate improvement over other calculators (like the one I linked) that only sipply numerical output. There is one effect that you might integrate into your calculation ... that is diffraction ... especially with smaller sensors, this effect becomes an important and visible factor relatively soon.

One little bug: you can have the background in front of your subject, then it looks funny. Perhaps a numerical check to make sure background is behind subjects? Correction. It doesn't quite work correctly. I first changed the focal lengths, and that seemed to work fine. However, when I do nothing else but change from F 2.8 to f1.8, it first works, but then the image gets updated only sporadically. I.e. the graph at the bottom is updated (when I click the calculate button), but the image at the right not always. Sometimes it gets updated when I press the enter key on the keyboard, instead of the "calculate" button.

It's fun to use and sure it is fancier than the one I use (the one Rainer already posted: http://www.dofmaster.com/dofjs.html). OTOH, I think the background blur in this calculator is not just calculated but also speculated... It changes from lens to lens...

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. |
