Hi 'Sach'. I'm not sure if you are looking for critique on this shot, as you've posted it along with no comments.
But, here it goes.
I think you've got something there as far as the composition goes. But there are too many other deterrents that override your good composition.
Firstly, the colours are way off. The water is yellow, the trees are yellow, and the sky is over saturated. If that was your intention, then forgive me for correcting you, but it doesn't work for me. Sorry.
Secondly, I'm glad you've found the adjustment brush in whatever post processing software you're using, but may I suggest a little more discretion next time? Or at least use a smaller brush, so that it's not quite as blatantly obvious as it is here.
Again, I hope you were looking for feedback, and I hope I wasn't too harsh, but maybe you'll take it as constructive criticism, and learn a little something. We're all here to help.
Agreed with Andrew on both the attributes and the weaknesses.
I wonder if you were using a polarizer. If so, you probably could have increased the visibility of the rainbow, which is barely noticeable.
@ Andrew and Mike: thanx for the feed backs, I am just learning how to do post processing photographs all by myself. These feed backs will definitely change my views on post processing, more feed backs are welcome. But please don't be too harsh as I've already told you I am new in post processing
Hi Sach, this looks to be an interesting image PP wise. I wonder what the raw or original image looked like. If you were to post the original image, I am sure there would be no shortage of people willing to have a go and then tell you what they have done. I think it could be a great learning experience.
WoW !! Looks like that Planet where 'AVATAR' was filmed !
I am new to PP as well.
What I am looking for in an image is a "natural to me look" that POPS.
In other words, the colours and image look natural, but it pops and grabs your attention.
Maybe because the colours are just that little more vibrant and crisp/sharp.
Or maybe because it is a starkly simple "clean" image.
As I look at some of my photos from the past, they are too cluttered, too busy, not nice and clean.
Anyway, enjoy your new hobby, it is fun.
And the people on this forum are amazingly helpful.
