Bradley,
This quite a beautiful landscape image. Picture - postcard. I’m really enjoying the colors, the blue sky with the puffy clouds… the reflection. This is a wonderful composition. Again on the colors, I think you’ve processed this quite nicely.
I had similar thoughts as Igor regarding the grasses at the bottom. In the end, I think they work great; they’re not cut off and have enough presence in the frame to work as almost an anchor, or resting place for the eye. The ONLY suggestion I do have would be to clone out the pieces of grass in the LRC, lower right corner.
Quite a number of variables here, so no clear answer, but here are my thoughts - and all just relevant to this particular image. The trees here are just one of the elements of this landscape image and so for me, it’s not critical that you have super sharp leaves; One thing, they’re too far away to really even notice if they’re sharp - and/or blowing in the wind. If the image was a closer look at the trees and they were the primary subject, then yes, sharpness might matter a bit more.
The other factors of course would be the aperture, depth of field and where was the focus point. At f/9 you’re probably going to have decent depth of field - depending on where you focused. The grasses at the bottom look pretty sharp, so I’m wondering if you focused there.
Not sure if you handheld or used a tripod? You should have been able to hand hold at 1/125th. And then there’s the sharpness of the lens itself.
but to your question of shutter speed… here in lies the consideration of “equivalent exposures” and those relationships between shutter speed, aperture and film speed. I order to “freeze” something you need pretty fast shutter speeds. The fast the shutter speed needed, the wider the aperature and/or higher the ISO. And the last two, aperture and iso, sharpness and noise are affected. If you stop down to your sharpest f/stop - maybe f/11? or whatever it is, the smaller the aperture, the longer the shutter speed. there’s always a give and take.
And so with that, there are techniques like focus-stacking where you can combine multple images to maximize sharpness in any given image.
Anyway, this may or may not have helped. In the end, IMHO with this particular scene, having leaves “tack sharp” probably isn’t at the top of my list. And lastly, really hard to judge sharpness with these small jpegs. This might be a good candidate if you’re up for it, to put in the “Image Process challenge” forum to see what others might come up with. You would have to upload the RAW image
Thanks for posting. This is my favorite of the images you have posted so far.
