The (now) green water of the Potomac ricochets through the dense rock of Great Falls, Virginia.
Another focus stack exercise. This time 5 images stacked at 14mm ~f/14, 1/6 sec, ISO 50. 5dm2 & 14-24
I purposely went a little darker here... perhaps too dark? Your thoughts? To really see you may should view large.

19 commentsYour focus stacking worked very well. It's a very dynamic image and I don't find it too dark at all.
Really nice.
You consistently come up with different/new perspectives on GFalls.
I really like the low angle and the water capture,of course the location you selected is outstanding also.
I am jealous
I like your processing and exposure, not too dark at all for my tastes.
Well done.
Just my personal take, but i kind of think a 5 image stack for focus might be overkill here. You probably could have hyperfocused at f/16 or so and got 99% of this in focus. The blend almost always causes issues. Im not sure if it's the blend or just the ss here, but for example there is a weird spot on the left side of the lrhc rock that looks like water on the lens or something.
Really nice regardless.
appreciate thoughts on the brightness of the image. looks to be about a 50/50 split.
stan - thanks for the comment re: focus stacking. while in the field, i tried to determine exactly how many frames i'd need for the most FG rock to the trees to all be as sharp as possible at something of a middle tier aperture (to use the lens at its peak setting for sharpness and limit the CA i often get with my lens -- does anyone else get significant CA with their Nikkor 14-24mm?). i think i was probably around f/11-f/14 in these frames (with the nikkor lens mounted on a canon I can never be sure). i guess what i'm saying is i tried my best to NOT stop down, perhaps tried a bit too much.
Good eye - on the left side of the RHC rock there was a bit of an issue with the motion due to the focus stack. when comparing to the original frame for that focal length, though, it wasn't significantly different so i alleviated it to an extent by cloning. I think i'll take another pass through now that you pointed it out though. overall, i was very pleased/surprised with the way Helicon focus handled the motion throughout the stacked image -- I really couldn't find any other aberrations.
thanks again for your comments...

On the positive side, I love the low angle perspective you chose, it makes for a very dynamic comp! Love that green color in the water as well!

You'll only notice the difference in the large file, which I have posted to Flickr (as to not post too large a file on NPN). Additional thoughts welcome:

Any interest in doing an outing with DC Metro (MD-VA) NPN'ers?
Or getting together on a somewhat regular basis?
I would be up for joining a DC Metro NPN get together.
