demo - f-stops / ISO / shutterspeed / light levels

I posted this on the other site, but thought it could be on here too. Hope it's OK to do that

I expect the stuff on here is old hat to most people, but I found this site a while ago and liked the way it explained things visually.

It shows what is likely to happen when you change a combination of f-stops (f2.8 -> f16), ISO (100 -> 1600) and / or shutterspeed (1s -> 1/1000s) in three different outdoor light (illumination) levels and with five different camera settings - auto, programme, aperture priority, shutter priority and manual.

At the top of the page it shows what happens to the aperture when the f-stop is changed. The main picture changes too, showing different depths of field and so on.

It's a bit of fun, even if you know what you're doing.

The site's here - camera demo -

Thanks

I put the same link on the other (international) site, some people have come back and said they caught trojans. I've visited this site quite a few times without any problems at all, so have other people I know. None of us has ever had a pop-up, never been asked to download anything, so what's happened comes as a bit of a surprise. I've followed the link again this evening, no problems at all.

This is what it says on the front page ....

I'm testing a new Flash movie designed to teach exposure concepts as they relate to digital cameras. Anyone can use it but it was originally designed for my students at the University of Oregon in the Digital Arts, Digital Imaging class. It still has a few rough edges and bugs, but you can try it out.

I have not had a problem with trojans from this site, I think it helps to keep all programs upto date otherwise these horible trojans can find a back door.
