Hi thoongeng,,
School just re-opened and not so many home work.

I am not some master or anything. I am still learning a lot and the beautiful part about learning photography is never ending...
There is a reason why this is the second time I commented on your photos. I find that you are helpful with some of the CS members and you actually bother to give C&C with encouragement. That is good and I would like to share with you what I know but I am still a newbie.
I am quite sure that most of us shoot in raw all the time. Take example of raw food.
Raw food we need to cook before we can eat. If you cook it properly with the right ingredients, it will really taste nice and delicious.
So for the raw files in photography, if you process it properly with the right tools and the right ways to extract those details, it will be really nice.
Of course, you will need lot of practice, reading, experiment and the result will not be disappointing. Talk is easy and if you don't try, you will never find out how.
What I'm saying here is that, taking a good shot with a good composition is as equal importance to a proper post processing.
If I remember. hyperfocal= focal length / aperture + CoC. Is this right?:think:
Anyway, I have not been using this hyperfocal for most of my shots. I have been using another method which is my own....

I'm not saying how...
I am also using the same lens as you and I don't find it sharp at all. My kit lens is much better in sharpness. If shooting at f16, it is terrible. Shooting below f16 is much better but still not sharp. i guess the lens is like this and I am not technical at all.
