Why not show the result in real time as you adjust the sliders? You can still show the preview off to one side or whatever. It would help develop a tighter iterative loop for experimenting and save the cognitive overhead of trying to remember what was wrong with the one before. Have some image 'troughs' which you can populate with screen grabs including the settings you used to allow quick reference to settings from…

willyt, the Mac/Windows version of this sim lets you see the effects of ISO, f-stop, and all those other "post-snap" adjustments in real time.

Yes, for people who understand how aperture relates to depth of field. But there seem to be a good number of people who understand what depth of field is, without understanding how to control for it using aperture.

Depth of field is controlled by aperture, focal length, and distance to subject. The degree to which the subject is actually isolated from the background is also very important. This simulator manages to bury one aspect of this information and ignore the rest. All else being equal, to increase subject isolation: * Get closer to the subject * Increase focal length ("zoom in") * Increase aperture operning (smaller aper…

Yes, this is indeed the case! I shoot with a prime, so the ability to change the focal length doesn't really come to me. But I think it's very important that you brought up specifically the fact that the distance spatially between the camera, the subject, and the background are very important!

Can you expand on that a little... I'm looking to buy a D5100, is this using the LCD or the viewfinder?

I do have d5100 and I confirm that there is no DoF Preview button. You can read about it's purpose here http://www.kenrockwell.com/tech/dof-button.htm If you really need this button d7000 have same sensor and does same quality photos. It allows for more control using physical buttons (in d5100 you need to use info menu to set some setting). It is also better suited then d5100 for manual lenses. That said it is also m…

Great, will read through the article and play around to see what the option does on my brothers Nikon D60 (I've been playing around with his camera before deciding whether to splash out). Great pictures, looked at them briefly, will look at them properly tonight. Thanks.
