Originally posted by Dartmoor Dave I had to be in Launceston for an appointment this morning, so I stopped by the castle to grab a snap. The castle is closed at this time of year, so this angle was the best I could manage without climbing over the fence -- which I couldn't do because there was a security camera pointing right at me. With the Takumar 17mm again. And for some reason, uploading to Flickr seems to have added a sort of faint crosshatching effect, at least on my monitor.
Nice photo! Glad you didn't get caught by security. haha :P
Below are some shots I took just now... I've been lamenting my K10D's low light performance lately (slow focusing, fuzzy shots) and so I decided to experiment with letting the camera go to ISO 1600. Per recommendations I've read online I've usually limited it to 800 max in the past. I figure if I can shoot a step higher in ISO it won't help with focusing but should reduce blur in my shots.
What I found is that the color noise can be handled quite nicely in post processing, and the grain noise I don't seem to mind at all... I think I actually like it. The colors are still great, maybe because of the CCD sensor, I don't know. I did find that I can adjust the exposure much, much less than an ISO 100 photo. Way less. So it's more important to get the exposure right - but when you do the images still look great (IMO). And another thing I found is that the high ISO noise is actually quite pleasant (again, IMO) in black and white photos!
One other observation is that high ISO and shadows do not mix well. But again, if I don't touch the exposure it is fine. If it's a bright scene I can actually adjust the exposure post-processing if need be, but dark scenes give no latitude at 1600. Still, if it's a choice between 1600 or 800 and a blurry shot, I think I'll be letting the camera go to 1600 from now on.
