Fun to try

This is so excellent! I can learn some of the basics and practice them. I was able to bring out several different things in just a few minutes with this and I can't wait to get more free time to play with it some more.

Super big Thanx!

Good learning tool! :)

yeah , real fun ! sad it has no DOF button

thanks for the tipp

Change the F-stop..

Interesting. But I've got the real thing, and the trash-button is easy for all those practice shots I'm not planning on keeping. The subject doesn't have to be anything worthwhile or interesing for such experiments.

I guess it's handy for those considering getting a camera with manual mode controls so they can see what's involved. One way to learn if that floats your boat and provides the artistic options you want, or if you want to stick with point-and-shoot.

This is a  good way to demonstrate reather than just talk about the relationships of ISO, aperture and shutter speed. I see this working pretty well in a class environment where everyone does not have a suitable camera. Honestly, for introduction, this would be faster and more class friendly than working with actual cameras. 

BTW, using manual mode it will also reasonably simulate results of rules of thumb like the "sunny sixteen"

A trick here is to get shallow dof and keep the pinwheel blurred...now that is a trick! It is easy to realize  that  light and action require compromises in what you can do.
