add a bit of contrast, reduce highlights, increase shadows, add white (watch histogram, don't go too far), add black (watch histogram again), add a touch of clarity (maybe some sharpening). Job done I might even leave the vegetation in the bottom as it adds a bit of interest (I find water a boring foreground, personally)
Pretty much what Jim said, although I don't bother with clarity. Coming from film (Velvia) you generally had to make a choice between blocked shadows and overdone highlights and I preferred the former (and still do).
But in all honesty, it's a bit of a nothing shot so there's not a lot that can be done with it.
Is it Llyn Crafnant, btw?
I can't see much to edit here. Tonally, nothing seems beyond the pale. I think more that it needed more attention at the taking stage.
The bit of shore at the right is an intrusive distraction. But overall, what's interesting here? Well there are those oak trees along the left, there's the texture of the ripples, and the hint of grasses bottom left ...
But as a whole image, it's somewhat generalised and vague, and needs more focus of interest.
Two things with landscapes (apart from judging the light) are deciding where to draw the frame, and where to focus, and all these things have to conspire together and integrate to form the image as a whole. So I'd go back there (if possible) and explore possibilties some more.
You could go low, for instance, focus on the foreground grasses, and let the distance blur - that's just an idea, not a recipe. It's about being adventurous, I feel - but more decisive too.
Sometimes a landscape overall might not hold much interest, but you can extract details from it.
Thankyou for all of the replies, there are some interesting and varied thoughts here
Now thats a point of interest
Toni, that last one of yours was fun, and interesting.
This one, I thought, was taking the p***, which is an unkind thing to do to a recent poster ...
As for Kipax's effort, well - an example of serious cultural depravity! (Culture = soccer in some circles. Counselling might be available ).
Apologies if this is posted in the wrong section. How would you edit this shot? I'm after peoples opinions with this one, other than cropping out the plants at the bottom.
