HDR and Low EV values

Look at these and the EV values: http://www.hdrsoft.com …ry/gallery.php?​id=2&gid=0

The EV= 1 or 2, these sites provide a calculator:

Is it a general rule to have or go for Low EV values for HDR photographs?

Thanks

You misinterpreted what you saw in the first link. The "EV" you see in the legend is actually the EV difference between the bracketed shots used for the HDR (1/30 , then -2EV = 1/125, then -2EV =1/500) The exposures are at f/8 and ISO 100 at those speeds so these were at EV11, 13 and 15; a series differing by 2EV!

Thanks, on the 40D one would then set f8, ISO 100 and bracket the shots. get three at EV11, 13 and 15. And then post process. The EV difference of 1 or two indicates the bracketing (makes more sense). Will check what the 40D supports for auto bracketing.

Thanks
