Thanks for that correction, must have been remembering my older D200.

That's why an EVF/LCD finder is so handy. It can easily ramp up the gain in dim lighting conditions to provide precise focusing and framing accuracy under conditions exactly like are available for this image. You're not very bright, are you. If only we could ramp up the gain between your ears. But then you can't even comprehend what an f-stop is yet. We've already all seen that joke of a discussion you had. I was hoping it would have gone on and on. So many free laughs, but you gave up trying to figure out how apertures work. >DOF is longer behind the subject than in front of it. > >This guy planned his shot and did a HDR: >http://www.flickr.com/photos/sharpshutter/4318395969/ > >Well done, you took the shot and I did not. >Anyone criticizing you should come up with something better or shut >up. > >DanP

To take that shot at 1/10,000 s you MUST use flash. CHDK would let you do it only at f/8 and maxing up ISO is still not enough. And you know how bad it is to go past ISO 800 with a P&S. No flash makes you a liar. Can be done with 1/200 s http://www.flickr.com/photos/csummers/1027755241/meta/ DanP |
