I don't know about you all, but I'm just amazed by this camera's abilities at high ISO speeds. Next I have to have some prints made but they look very good to my eyes even at their largest sizes. And I'm talking about in color, too. Most of you will remember my claim of taking this picture at an ISO of 64,000 - it was really a mistake in my zeroes, not an on purpose exaggeration. In reality it was taken at 1/2500 @ f/8 ISO 6400 <a href="http://www.flickr.com/photos/otra/5727745915/" title="5-11-205-Edit-2.jpg by BBW: BB Wylie Walden, on Flickr">"1024" height="680" alt="5-11-205-Edit-2.jpg"></a> I have a whole bunch of photographs from our daughter's graduation that I am slowly making my way through. Don't worry, I promise I won't post them all here, but I thought it might be interesting for some of us to show examples of high ISO images that we think have worked out well. Here's one example of a photograph at 1/55th @ f/2.8 ISO 5000. In this case I did use Nik's Define directly from the DNG file - just their automatic setting.. I don't really know how to use it but I used it. Then I used Color Efex Pro Contrast...then back into Lightroom and did my own thing. If anyone has any interest you can see two other versions of this picture - one with no noise compensation...and one with just using LR's de-noise slider...if you click here. <a href="http://www.flickr.com/photos/otra/5815561538/" title="5-11-251-Edit-2-Edit.jpg by BBW: BB Wylie Walden, on Flickr">"1024" height="680" alt="5-11-251-Edit-2-Edit.jpg"></a> I hope others will add their pictures here if they were taken at what most of us would consider high ISO speeds because I think this is one of the X100's highlights. Of course it makes great photos at ISO 200, too.
